Who Mochi is best for
Developers and automators
Pro includes an HTTP API and API keys for reading and writing cards, so scripts can add cards from notes, code or other tools.
Privacy-minded learners
Free stores cards locally with no sync, and the privacy page says Mochi does not store data on its servers without an account.
Language learners
The page lists dictionary lookup, translation, transcription and text to speech, which fit word cards better than long prose, so a vocabulary learner can look up a term and make a card from the result.

What Mochi does
- Offline-first editor
- Cards are edited and reviewed locally on desktop and mobile apps, so studying does not need a connection. The Free plan keeps cards on the device with import and export, while sync is a Pro feature.
- AI completion
- The AI makes cards and rewrites text from your prompts, within a monthly token allowance that resets on the first of the month. Free allows 5,000 tokens and Pro 500,000, and the page lists no deck generation from files.
- Dynamic fields
- On Pro, card content can be filled from a data source, which helps with templated cards such as vocabulary lists, where the same fields repeat across hundreds of entries and are better pulled in than typed.
- Deck publishing
- Pro users publish decks by link or in the deck library, so a teacher can share a set without a classroom tool. Anyone with the link can then study it, and Free users cannot publish.
- HTTP API
- Pro API keys allow programs to read and write cards, with card templates available on both plans. Rate limits and endpoint documentation were not on the pricing page, so check the docs first.
How Mochi handles your data
The privacy page says the Free plan stores data on the user's own computer and that Mochi does not store data on its servers unless you have an account. It also says Pro data is not encrypted in the database. The pages we read name no hosting region, no retention period, no certification and no position on training AI models, so those are unverified. Free usage limits reset on the first of each calendar month and unused amounts do not carry over.
Where Mochi falls short in practice
- Free AI is tiny. 5,000 tokens and 20 dictionary lookups a month run out within a few sessions, so regular AI use needs Pro, and a few long prompts or a batch of lookups can empty the Free allowance within one study session.
- No server-side encryption at rest. The privacy page says Pro data is not encrypted in the database, which rules it out for sensitive study material, and a learner should keep such cards on the Free plan, where data stays on the computer.
- Allowances do not roll over. Unused tokens and lookups vanish each month, so a quiet month does not build credit for exam season, and heavy users should compare the 500,000 Pro tokens with their real use.

Mochi: common questions
How much does Mochi Pro cost?
As of November 2026, Pro is $5 a month billed annually, and the page also offers a pay-monthly option whose price was not read. The page says yearly billing saves $12 a year. Free is $0 forever with unlimited offline cards and decks. Pro includes a Try it free button.
Does Mochi have an API?
Yes, on Pro. API keys let you read and write cards through an HTTP API, which is rare among flashcard apps at this price. Free has no API keys. The pages we read do not list rate limits or endpoint documentation, so check the docs before building anything on it.
What AI can Mochi do?
The page describes AI completion that makes cards and rewrites text, plus translation, dictionary lookup, transcription and text to speech. Free is capped at 5,000 tokens a month and 20 dictionary lookups, and Pro at 500,000 tokens and 1,000 lookups. It does not describe generating a deck from a PDF.
Is Mochi data encrypted?
The privacy page says Pro data is not encrypted in the database. On Free, data stays on your own computer and Mochi says it does not store it on its servers without an account. If you hold sensitive material, keep to the Free plan or read the full privacy page first.
Can Mochi work without an internet connection?
Yes. Mochi describes itself as offline-first, with unlimited offline cards and decks on the Free plan and apps for Mac, Windows, Linux, iOS and Android. Sync, publishing and the API need a Pro account, so offline use on several devices requires Pro to keep the copies aligned.
