How we grade them
| 3.0GPATettraVery good | 3.0GPAYou Need A WikiVery good | |
|---|---|---|
| Value for money | BScaling is $8 a user a month billed yearly, or $10 monthly, which is under what's typical here, and AI answers, the Slack bot and the API are all in. But the 10-user minimum sets the floor at ten seats, and SAML SSO and SCIM are paid add-ons unless you go Enterprise. | A$19 a month covers up to 10 users, and that's for the whole team, not each. $49 covers 25 and $99 covers 75, all with the same features and unlimited read-only users. Hard to find a team wiki for less. It's monthly billing only, so there's no annual discount. |
| Free plan and trial | CNo free plan. The trial is a decent one, though: 30 days with all features included and no credit card required. When it ends, you need a card to carry on. | BOne user can use it free, with the same feature set the paid tiers list. Fine for a wiki you write alone and share read-only. The moment a second person needs to be a user, it's $19 a month, and no trial of the paid tiers is listed. |
| Features | APages you write or build from Google Docs and Markdown files, a store of answered questions, and Kai answering from all of it in Tettra and Slack. Experts verify pages on a schedule, and reports list what's stale or unowned. Read-only users, guests and page locking round it out. | BIt does one thing and does it fully: Drive folders become a wiki with a nested tree menu, search inside the documents, team or public sharing, a read-only mode and a custom domain alias. Editing and live collaboration come from Google Docs. That's the whole list, though. |
| Ease of use | BNo rating on record to go by, so a B is as high as we go. It's used in a browser and through Slack, so there's nothing to install, and you can bring in the Google Docs you already have. The interface is English-only. | BNo rating on record, so a B is as high as we go. There's nothing new to learn, since pages are just Google Docs. You do have to share the wiki folder with a You Need A Wiki service account so its server can act on the files. |
| Platforms and integrations | BWeb only: Tettra's site lists no desktop or mobile apps. It works through Slack and connects to Google Workspace, GitHub and Zapier, with API access on the Scaling plan. | CA web app and nothing else. The only things it connects to are Google Drive and Google Docs, because that's where every page lives. You can embed a wiki in another page as an iframe, and that's about it. |
| Best for | Slack teams tired of answering the same question | turning a Google Drive folder into a wiki |

Key features
Tettra
- Internal knowledge base
- Pages are written in Tettra's editor or built from existing Google Docs, Markdown files and other content, then grouped into categories with unlimited version history.
- AI answers from Kai
- When someone asks a question in Tettra or Slack, the Kai bot searches the knowledge base and replies. If it finds nothing, it helps assign the question to the right person.
- Questions and answers
- Questions and their answers are stored alongside pages, so a question that has been answered once can be found again instead of asked again.
- Verification and content reports
- Subject-matter experts verify pages on a set schedule, teammates can request new pages or updates, and reports list stale, unowned and public content.
- Slack integration
- From Slack, teammates can search Tettra, get AI answers in channels and direct messages, summarize threads and turn existing answers into knowledge base content.
- Sharing and permissions
- Single pages can be shared by link and whole categories published as external sites. Read-only users, guest users, invite-only categories and page locking control access.
You Need A Wiki
- Wiki from existing Drive folders
- Existing Google Drive folders and files are imported into a wiki with a nested tree menu. Changes made in Docs or Drive show up in the wiki, and everything is saved to Drive.
- Google Docs as the editor
- Pages are edited in Google Docs, so live collaboration, suggestions and formatting come from Docs. The wiki shows who last edited a page.
- Search across document content
- Search covers the text inside documents. To speed it up, document content is cached for up to a month, which can be turned off in settings.
- Team, contact and public sharing
- A wiki can be shared with a team or individual contacts or made publicly accessible. Read-only users are unlimited, and a read-only mode guards against accidental edits.
- Custom domain and embedding
- The plans list a custom domain alias, a custom sidebar color and the option to embed a wiki in another page as an iframe.
