What are the best Guru alternatives?
The best Guru alternative depends on which half of Guru you actually use. Guru does two jobs: it keeps a library of short answers verified by named owners, and it answers questions from that library inside Slack, Teams and the browser. Most alternatives do one of those jobs well, so name yours first.
If verification is the job, look at the wiki you already pay for. Notion Business includes "Verify any page", and the verified badge carries into Notion's search and AI citations. Tettra is the closest match to Guru's old model, with verification and a Slack bot at $8 per user per month billed yearly, though it has a 10 user minimum like Guru did. Slite sells a similar team wiki with AI answers at $10 and $20 per member.
If a curated hub with a services team is the job, Bloomfire is the comparable purchase. It also sells by quote, on multi-year terms, and its strength is searching the spoken word in recorded video.
If the real complaint is that people cannot find answers, a second library usually makes it worse, because it adds another place to look. The fix is a search layer across the tools where the answer already lives. Glean is the category leader and sells by quote. InSearch connects Drive, Slack, Notion, Confluence, Gmail, Jira and Salesforce, enforces each source's permissions at query time and returns one written answer with citations, at $20 per user per month for Drive, Slack and Notion on Team or $32 on Business with all seven connectors.
