Glean vs Tettra
Side-by-side comparison of features, pricing, ratings, and alternatives.
Glean is an enterprise AI platform that connects an organization's knowledge across more than 35 applications, including Slack, Google Drive, Jira, Confluence, SharePoint, GitHub, and Salesforce, to power permission-aware search and answers. Beyond search, Glean lets teams build custom AI agents without code on top of that connected knowledge layer, positioning itself as a horizontal workplace productivity platform rather than a single point tool.
Tettra is an internal knowledge management platform built to stop teams from re-answering the same questions in Slack. It centralizes company knowledge imported from Google Docs, PDFs, and Notion, and its AI bot, Kai, searches that content to answer employee questions instantly, in-channel or via direct message.
- Connects a very wide range of enterprise apps rather than a narrow set
- Permission-aware search reduces the risk of surfacing content a user shouldn't see
- No-code agent builder extends beyond search into workflow automation

- Built for large organizations with many connected systems, likely overkill for small teams
- Value depends heavily on how much of the org's knowledge actually lives in supported integrations
- Scaling plan has a 10-user minimum, which raises the entry cost for very small teams.
- No public free tier; pricing requires a paid subscription after the trial.
- Enterprise pricing is not published and requires contacting sales.
