Tettra: cost, fit and limits
Tettra is an internal knowledge base made by Tettra, Inc. that stores company documentation and uses an AI bot called Kai to answer questions in Tettra or Slack and route unanswered questions to the right person, for teams that run on Slack.
What to know first
Tettra sells per-user plans named Basic, Scaling, Professional and Enterprise, with a 10-user minimum on the per-user plans. Basic and Scaling have a free trial and then require a card, while Professional and Enterprise add invoicing and ACH or wire payment. Amounts were not captured. Kai answers from the knowledge base and escalates when it cannot, and the product also generates FAQs and summarizes threads.

Who Tettra is best for
Slack-first companies
Kai answers in Slack and Tettra, and sign-in with Slack keeps access simple for teams that already live in that tool.
Teams moving docs from other tools
Import from Google Docs, Notion and local files means a team can bring an existing set of documents without retyping them.
Support-heavy internal teams
When Kai cannot answer, it finds the right person to respond, which helps teams where answers sit with a few experts.
Tettra plans and pricing
| Plan | Price | What it includes |
|---|---|---|
| Basic | Not captured (per user per month) | Free trial, then a card is required. Per-user pricing carries a 10-user minimum, according to the pricing page. |
| Scaling | Not captured (per user per month) | Free trial, then a card is required, under the same 10-user minimum that applies to the per-user plans. |
| Professional | Not captured (per user per month) | Adds invoicing and ACH or wire payment options, so a finance team can pay by invoice instead of by card. |
| Enterprise | Custom pricing | Discounted per-user rates past 250 licenses, arranged by contacting sales, plus the invoicing and ACH or wire options. |

What Tettra does
- Documentation editor
- An internal documentation editor, with import from Google Docs, Notion and local files, so a team can start from documents it already has. The pages do not state a page or storage limit for any plan.
- Kai AI bot
- Kai searches the knowledge base and answers questions in Tettra or Slack, so staff get an answer without opening the wiki. The bot is the center of the AI pitch, and the pages do not state an accuracy figure.
- Escalation to a person
- When Kai cannot answer, it finds the right person to respond, which routes gaps to a human and surfaces missing documentation. That makes gaps in the documentation visible, because each unanswered question points to a missing page.
- Slack integration
- Slack notifications and a sign-in with Slack keep Tettra inside the chat tool where questions are asked in the first place. The Slack link covers both notifications and login, which cuts one more password for staff.
- AI FAQ generation
- Generates FAQs from content, so a team can build a question list from existing pages without writing each entry manually. The vendor lists this next to Kai, and the pages do not state an output limit.
- AI thread summaries
- Summarizes Slack threads, so a long discussion can become a short record that is easier to turn into documentation. The summary can then be saved as a page, though the pages do not describe how that step works.
How Tettra handles your data
The pricing page and homepage opened for Tettra did not state where data is hosted, how long it is retained, whether customer content trains Kai or the FAQ and summary features, or which security certifications the company holds. Kai reads the knowledge base and Slack content, so the question matters in practice. Payment terms differ by plan, with invoicing and ACH or wire on Professional and Enterprise only. A buyer should ask for the security documentation, the data processing agreement and the AI subprocessor list before connecting a Slack workspace.
Where Tettra falls short in practice
- Ten-user minimum. Per-user plans require at least 10 users, so a small team pays for ten seats or looks elsewhere, whatever the actual headcount. The pricing page calls it a minimum, so a smaller team cannot choose fewer seats.
- Card after the trial. Basic and Scaling require a credit card after the free trial, and invoicing or ACH is reserved for Professional and Enterprise, which affects finance teams.
- No prices or security detail. Amounts per plan and any certification or training statement were not captured, so a buyer must gather them directly before comparing against tools that print prices.

Alternatives to Tettra
Tettra: common questions
Is there a minimum number of users for Tettra?
Yes. The pricing page states a 10-user minimum on the per-user plans. A team of five would pay for ten. Enterprise offers discounted per-user rates past 250 licenses, so the plan structure favors mid-sized companies over very small ones. Larger teams that exceed 250 licenses can ask about discounts.
What happens after the Tettra free trial?
Basic and Scaling have a free trial and then require a card. Professional and Enterprise add invoicing and ACH or wire payment. The pages did not state trial length, so ask how long it runs and what happens to the content if you do not convert.
What does Kai do in Tettra?
Kai is the AI bot that searches the knowledge base and answers questions in Tettra or Slack. When it cannot answer, it finds the right person to respond. Test it with questions your staff actually ask, and look at how many need a human.
Can I import documents into Tettra?
Yes. The vendor lists import from Google Docs, Notion and local files. The pages did not describe formatting fidelity or limits, so import one representative folder first and check headings, tables and images before moving the whole library. Ask the vendor whether images embedded in a Google Doc come across.
Does Tettra publish its prices?
The captured pricing page showed per-user pricing for Basic, Scaling and Professional but the amounts were not captured, and Enterprise is custom. Open the live page for current figures, and ask whether Kai and the AI features are included in every plan.
