Best AI Captioning and Subtitling Software in 2026
AI captioning and subtitling software turns the speech in a video or audio file into timed text, then lets you edit, translate, style and export it as captions or subtitle files such as SRT, using speech recognition and machine translation. It is not a plain transcript service, and it is not a full video editor, although several vendors sell both in one account.
Quick answer
Happy Scribe ranks first because its plan prices, language counts, SOC 2 claim and opt-in training policy are all printed. Sonix suits teams that pay by the hour and want a written no-training promise. Kapwing suits creators who edit and caption in one browser.
A buyer of captioning software usually has one of three jobs: subtitles for a backlog of recorded video, burned-in captions for short social clips, or live captions for a classroom, broadcast or event. The products behind those jobs differ more than their landing pages suggest. Some bill by the audio hour, some by video count, and the enterprise vendors publish no price at all. This ranking weighs printed prices, stated language coverage, what the vendor says about training on your files, how easily subtitles leave the product, and how much of the plan is gated behind a sales call. We read vendor pages in November 2026 and ran no tool, so accuracy claims are the vendors' own.

Happy Scribe ranks first because a buyer can check more of it than of any rival. Five plans are priced in euros, speech-to-text covers 150+ languages, and the privacy policy calls model training opt-in and describes a SOC 2 Type II audited program. Human proofreading is sold by the minute. The weak spots are a thin free tier for uploads and conflicting seat prices on Pro and Business.
Strong on
- Speech-to-text in 150+ languages and AI translation in 80+ languages
- Training on customer data is described as opt-in in the privacy policy
- Free plan exports SRT and TXT, so subtitle files can be tested at no cost
Weak on
- Free allows only 10 one-time minutes for uploaded files and watermarks MP4 exports
- Pro and Business list extra-seat prices of both €19 and €29 a month
Skip it if: Teams that need live captions for events or a named human-reviewed accuracy commitment, which the pages do not describe. Free covers 45-minute recordings and SRT export; Basic is €17 monthly or €8.50 billed annually.
- 2
Sonix takes second place on clarity of terms. Pay As You Go is $10 an hour with no subscription, three subscription tiers separate transcription hours from AI workspace hours, and the security page states that customer media is never used for training. SOC 2 Type 2 and HIPAA through Medical Sonix are named. Data is stored in the USA, and other regions are an Enterprise arrangement.
Strong on
- Security page says audio, video and transcripts never train Sonix models on any plan
- Pay As You Go is prorated to the second, so light users avoid subscriptions
- SOC 2 Type 2 is stated, with HIPAA support through Medical Sonix and BAAs
Weak on
- All customer data sits with AWS in the USA unless an Enterprise deal says otherwise
- Core includes only 5 hours a month, with email support answering within 48 hours
Skip it if: Buyers who need EU data residency on a self-serve plan, since non-US storage is a custom Enterprise arrangement. Pay As You Go bills per hour of media with no subscription; the 30-minute free trial needs no credit card.
- 3
Maestra ranks third because the plan ladder is printed and the upper tiers add real controls. Premium at $79 a month brings API access, Teams and OpenAI translation with prompts, and Business adds DeepL and a translation glossary. The policy states US hosting and about 30 days of retention after service ends but says nothing on model training, which keeps it below Sonix on data clarity.
Strong on
- Premium adds API access, Teams with central billing and AI rewriting of subtitles
- Translation engine is selectable: OpenAI with prompts or DeepL on higher tiers
- Pay As You Go credit packs avoid a subscription for occasional jobs
Weak on
- Policy gives no statement on training with customer data and no certifications
- Pay As You Go is sold only in 60-credit packs, and translated subtitles use credits twice as fast
Skip it if: Buyers who need a documented no-training commitment or EU hosting, as the policy names US hosting only. Pay As You Go sells 60-credit packs; a free trial is named but its length and terms are not stated.
- 4
Kapwing ranks fourth because captions are one feature of a larger editor. Free offers auto-subtitling up to 10 minutes, Pro lists 1,000 subtitle minutes a month with 4K and no watermark, and Business lists 4,000. The pricing page does not state whether $16 and $50 are monthly, and the privacy page returned no usable text, so data handling is unchecked.
Strong on
- Auto-subtitling is included on Free, with 1,000 minutes a month on Pro
- Pro and Business export up to 4K with videos up to 120 minutes
- Subtitles and editing happen in the same project, which saves a round trip
Weak on
- Free plan caps videos at 4 minutes, 720p and 30 export minutes a month with a watermark
- Training and retention policy was not checked because the privacy page returned no text
Skip it if: Teams that need subtitle files, human review or compliance documents, since the pages describe captioning only as an editor feature. Free caps videos at 4 minutes with a watermark; Pro is listed at $16 without a stated billing period.
- 5
Submagic sits fifth as a specialist for vertical clips. Starter prices at $19 per member with 15 videos and a 2-minute cap, Pro at $39 allows 5 minutes, and Business at $69 allows 30. AI Auto Captions, AI Translate captions and caption templates are named. Short length caps, an unclear API figure on the pricing page and an unreachable privacy page hold it back.
Strong on
- Starter lists AI Auto Captions and AI Translate captions, plus AI Clean audio and Hook titles
- Pro adds AI Auto zooms and Storyblocks b-rolls and audio
- Business reaches 4K at 60 FPS and videos up to 30 minutes
Weak on
- Starter caps videos at 2 minutes and 15 videos a month
- Pricing page lists API and integrations at both 100 and 10 minutes a month
Skip it if: Teams captioning long lectures or webinars, since even Business stops at 30-minute videos. Starter is $12 per member monthly when billed yearly; a free try is offered but its terms are not stated.
- 6
Zubtitle ranks sixth because it is simple and its policy is clear, but its limits bind quickly. Guru at $19 covers 10 videos a month, Agency at $49 covers 30, and the free plan adds a watermark at 720p. The privacy policy says content is not used to train public or generalized AI models. The Guru yearly price appears as both $190 and $90 on the pricing page.
Strong on
- Privacy policy states content is not used to train public or generalized AI models
- Brand styling, fonts and progress bars come with every plan including free
- Resizing presets exist for TikTok, Instagram, YouTube, LinkedIn, Facebook and Twitter
Weak on
- Video counts are small: 2 a month free, 10 on Guru, 30 on Agency
- Guru yearly price shows as both $190 and $90 on the pricing page
Skip it if: Agencies and educators who caption long or high-volume recordings, since plans count videos and Guru lists a 20-minute upload limit on annual billing. Bootstrapper allows 2 videos a month at 720p with a watermark; Guru is $19 monthly or $190 yearly.
- 7
Captions ranks seventh because captioning is now one tool among many AI video features. The free plan has one caption template and no AI credits, Max at $24.99 on iOS gives 500 credits, and Frontier tiers run to $139.99. The terms grant a license to use content to improve products without a clear training statement, and the vendor name varies across pages.
Strong on
- Caption templates grow from 1 on Free to 100+ on paid plans
- Captions in 100+ languages, with AI Translate, Lipdub and Voiceover
- Max and Frontier add chat-based editing and AI Edit styles
Weak on
- Free plan includes no AI credits and only one caption template
- Terms license Input and Output for improving products, with no explicit training exclusion
Skip it if: Buyers who need subtitle files, team administration or a stated data policy, since the pages we read describe an editing app. Prices shown are iOS plan prices in USD excluding taxes; yearly prices are not listed.
- 8
Amara ranks eighth because the editor and review workflows are real but little else is published. The homepage describes a cloud subtitle editor with waveforms, role-based review and approval, YouTube and Vimeo import and export, an API and Amara On Demand with human linguists in 50+ languages. No prices, free plan, training or hosting statements appear, and Auto Captions are named without detail.
Strong on
- Customizable review and approval workflows with role-based permissions for team subtitle projects
- Import and export with YouTube, Vimeo and other video hosts
- Amara On Demand offers human subtitles in 50+ languages
Weak on
- No platform prices, free plan or trial are named on the homepage
- Auto Captions are mentioned with no detail on languages or accuracy
Skip it if: Buyers who need a fast, self-serve automatic captioning price and a stated data policy before talking to anyone. No prices are published on the homepage; Amara On Demand invites a pricing request.
- 9
Verbit ranks ninth because the product breadth is wide while the buyer-facing facts are few. Captivate Live, Captivate Post, Enterprise Capture and Campus Complete cover live captions, post-production captions and audio description, with AI captioning in 100+ languages and live translation in 117. Every plan is quote only, and the privacy policy says customer data is used to improve its speech recognition.
Strong on
- Campus Complete bundles live and post-production captions, audio description and translation
- Multilingual AI captioning in 100+ languages with live translation in 117
- Zoom and Microsoft Teams integrations are named, with API on Custom Plan
Weak on
- No prices, free plan or trial are published
- Privacy policy says Customer Data improves its recognition engine; the opt-out was not checked
Skip it if: Individual creators and small teams, since buying starts with a demo and no self-serve plan is listed. No prices, billing basis or trial are published; every plan routes to a demo or sales call.
- 10
3Play Media ranks tenth because the homepage supports a service pitch but few checkable facts. It sells captioning for recorded video, scheduled live captioning and captions integrated into video platforms, described as 99%+ accurate. Pulse is named as AI-powered accessibility insights that route low-accuracy content to human review. No prices, legal entity, country or data policy were found on the opened pages.
Strong on
- Recorded, scheduled live and platform-integrated captioning are all offered
- Pulse audits video libraries and routes weak content to human review
Weak on
- Pricing page returned 404 and no price is on the homepage
- Privacy policy was not opened, so data handling is unchecked
Skip it if: Teams that want a self-serve AI tool with printed prices, because the pages describe a service sold through contact. No prices are on the homepage and the pricing page returned a 404, so no plan was verified.
- 11
AI-Media ranks last of the eleven because its LEXI line targets live and broadcast environments, which sit furthest from a self-serve subtitle workflow. LEXI Text produces AI live captions, LEXI Recorded handles recorded media, LEXI Translate and LEXI AD add translation and audio description, and an on-premises option exists. No prices, legal entity, country or data policy are on the opened page.
Strong on
- LEXI Text provides AI-generated live captions, with LEXI Voice for live voice translation
- LEXI Local on-premises option and LEXI DR disaster recovery are named
Weak on
- Live products depend on a hardware encoder or cloud encoder plus a viewer
- Hardware-as-a-subscription has a minimum 12-month term and no published price
Skip it if: Creators and small teams captioning recorded files, since the offer centers on live encoders and sales conversations. No prices are published; buyers are directed to an account manager, and the LEXI Encoder carries a minimum 12-month subscription.
How these AI captioning and subtitling software were judged
How accurate are AI captions, and who checks them?
Vendors rarely publish measured accuracy, so read the claims as claims. 3Play Media describes its integrated captioning as 99%+ accurate and routes low-accuracy content to human review. AI-Media says its LEXI Text live captions rival human quality. Happy Scribe lists speech-to-text in 150+ languages and Verbit and Captions each list 100+. Amara names Auto Captions without saying how they work. None of these figures replaces a test: upload a two-minute clip with accents, product names and crosstalk, then count corrections and time spent fixing line breaks and timing.
What does AI captioning software cost?
Self-serve entry prices run from free to about $25 a month. As of November 2026, Happy Scribe Basic is €8.50 billed annually with 120 minutes, Sonix charges $10 per hour pay as you go, and Maestra sells 60 credits for $12. Zubtitle Guru is $19 for 10 videos, Submagic Starter $19 per member, and Captions Max $24.99 on iOS. Kapwing lists Pro at $16 without naming the billing period. Amara, Verbit, 3Play Media and AI-Media publish no prices, so budget time for a sales call before comparing them.
Do captioning tools train on your videos?
Policies differ sharply. Sonix states it never uses customer audio, video or transcripts to train its models on any plan or trial. Happy Scribe describes training as opt-in. Zubtitle says content is not used to train public or generalized models. Verbit says customer data helps improve its speech recognition, and Captions grants itself a license to improve its products without a clear training statement. Maestra's policy is silent on training. For Kapwing, Submagic, 3Play Media and AI-Media, we did not check the policy, and Amara states nothing on its homepage.
How easily can you move subtitles to another tool?
Subtitle files are portable, styled captions are not. Happy Scribe exports TXT and SRT even on Free, with all formats from Pro, and Amara imports from and exports to YouTube and Vimeo. Editor-led tools such as Kapwing, Submagic and Zubtitle mostly deliver captions burned into video, so the styling stays behind if you leave. Sonix keeps files after a subscription ends, Maestra deletes data roughly 30 days after service ends, and AI-Media's live encoder carries a minimum 12-month hardware subscription. Export your SRT files before canceling anything.
Which captioning tool fits which job?
Match the tool to the footage. A multilingual interview archive fits Happy Scribe or Sonix, while Maestra suits developers who want API access from its Premium tier. Vertical social clips fit Submagic, Zubtitle, Captions or Kapwing, depending on how much editing surrounds the captions. Reviewed subtitle translation with approval roles fits Amara. Lecture capture, broadcast and legal proceedings point to Verbit, 3Play Media or AI-Media, where live service and compliance documents matter more than a monthly price. Verbit's Campus Complete names ADA Title II and WCAG 2.1 AA.
How to choose an AI captioning and subtitling tool in three steps
- Sort your footage by job and count minutes. Split next quarter's video into live events, recorded backlog and short social clips, then total the minutes in each. Hourly or minute-based tools such as Sonix and Happy Scribe suit the backlog, video-count plans such as Zubtitle suit clips, and live work needs a quote from Verbit, 3Play Media or AI-Media. A rough minutes-per-month figure also shows which allowance is realistic, for example 120 minutes on Happy Scribe Basic or 360 on Maestra Basic, before you compare entry prices. Round up, because real footage always grows.
- Run one hard clip through two or three free tiers. Pick a clip with fast speech, an accent and named products. Happy Scribe Free, the 30-minute Sonix trial, Kapwing's free auto-subtitling up to 10 minutes and Zubtitle's free Bootstrapper plan all let you test without paying. Compare the number of corrections per minute, how the editor handles line breaks, and whether the translation of one sentence reads naturally to a native speaker. Note watermarks and resolution caps so the test reflects what a paid export would look like. Keep the same clip for every tool.
- Check data terms and the export before you commit. Read the privacy policy for training language, retention and hosting region, then export one finished subtitle file and open it in a text editor. A clean SRT or VTT proves you can leave. Ask the vendor in writing about anything the page does not state, such as Submagic's or Kapwing's training policy, which we did not verify. If a publisher or school requires accessibility compliance, ask which standard the vendor documents and who signs off the human-reviewed tier. Keep the answers with your records.
Frequently asked questions
What is the best AI captioning and subtitling software in 2026?
Happy Scribe ranks first here because it prints five plan prices, lists 150+ speech-to-text languages, describes training as opt-in and states a SOC 2 Type II audit. Sonix is the pick for hourly billing with a no-training statement, and Kapwing suits creators who want captions and editing in one browser tool.
Is there free AI captioning software worth using?
Yes, within limits. Happy Scribe Free exports SRT and TXT but gives only 10 one-time minutes for uploads and watermarks MP4 files. Kapwing Free allows auto-subtitling up to 10 minutes with a 720p watermarked export, and Zubtitle Bootstrapper allows 2 videos a month at 720p with a watermark. Sonix offers a 30-minute trial instead of a free plan.
How much does AI subtitle generation cost per hour of video?
It depends on the billing model. Sonix pay as you go is $10 per hour of media, prorated to the second. Maestra sells 60 minutes of subtitles for $12, which is $12 per hour at its smallest pack. Subscriptions lower the rate if you use the allowance, for example Happy Scribe Basic at 120 minutes a month. Enterprise vendors quote privately.
Can AI captioning replace human captioners for compliance?
The vendors treat it as a first draft for regulated work. 3Play Media routes low-accuracy content to human review, Verbit sells an optional human quality layer in Post Plus, and Amara offers human linguists on demand. If a regulator or contract requires a stated accuracy level, ask the vendor which tier carries that commitment in writing.
Which captioning tools state that they do not train on customer files?
Of the tools we read, Sonix states it never trains on customer audio, video or transcripts, and Zubtitle says content is not used for public or generalized AI models. Happy Scribe says training is opt-in. Verbit says it does use customer data to improve recognition. For several others the policy was not checked.
Do captioning tools support translation into other languages?
Most do. Happy Scribe lists AI translation in 80+ languages, Submagic has AI Translate captions, Captions lists translation and 100+ caption languages, and Maestra translates through OpenAI or DeepL depending on plan. Verbit lists live translation in 117 languages on Enterprise Capture. Quality varies by language pair, so test yours before buying.
What is the difference between captions and subtitles?
Captions transcribe speech and usually mark speaker changes and sound effects for viewers who cannot hear the audio. Subtitles assume the viewer can hear and translate or transcribe the dialogue. Verbit's Captivate Post lists sound-effect labels for captions, while tools such as Amara and Maestra emphasize subtitle translation. Most products on this list produce both from the same transcript.
Which tool is best for short TikTok and Reels captions?
Submagic, Zubtitle, Captions and Kapwing target that job with styled caption templates. Submagic Starter limits videos to 2 minutes and 15 a month, Zubtitle Guru covers 10 videos a month at $19, and Kapwing Pro allows videos up to 120 minutes. Pick by monthly video count and how much editing you do around the captions.
