Guru positions itself as an enterprise governed knowledge layer, with expert-verification workflows that automatically flag stale or conflicting content. Inside Slack, any message or thread becomes a Guru Card from the message menu, and a Knowledge Agent auto-suggests cited answers or responds to @guru mentions — inheriting Slack permissions directly, with approved channels becoming governed knowledge sources.
The reason to look elsewhere is usually that answering questions isn't the whole job.

If people need teaching, not answering: Poplearn
A knowledge base is pull-based — it serves people who know they have a question. It does nothing for the new hire unaware the expense policy exists, or the compliance rule requiring everyone to confirm they've read the code of conduct.
/courses new turns a document into modules with quizzes written automatically. /assign #support pushes it to a person, a channel, or every new hire from that date forward, with reminders. /progress gives live completion by team, exportable when someone asks for evidence.
That record is the capability no knowledge base provides: proof a specific person completed specific training on a specific date. Free under 20 seats.
Poplearn has no search and no answer agent — it complements a knowledge base rather than replacing one.
If you want a simpler wiki: Slab
A knowledge base aimed at whole-organisation documentation, with /slab search in Slack, a shortcut converting messages into posts, Slack SSO, and unified search across connected tools like Google Drive and GitHub.
Less governance than Guru, more pleasant to write in.
If you want docs and projects together: Nuclino
Docs, wiki, and project coordination in one workspace, with List, Board, Table, and Graph views — the Graph maps the whole workspace. Used by teams at NASA, Ubisoft, MIT, and Paddle, and publishable as a public wiki.
If processes aren't written down: Trainual
AI-generated SOPs captured as you work, including screenshots, combined with training, meetings, goals, and action tracking. Strong SMB fit.
If you want answers and courses together: Continu
Its Eddy agent delivers cited answers and training content inside Slack, Teams, and SMS, with Smart Segmentation routing content to employee, partner, and customer audiences through branded portals.
The closest thing to Guru plus an LMS in one product.
If you want an AI tutor: Sana Labs
AI-first since 2016, with an AI Tutor answering from company-specific knowledge, direct document-to-course conversion, and LMS, LXP, authoring, and virtual classroom in one platform.
Where to start
If Guru works for answers and the gap is onboarding or compliance, you don't need a Guru replacement — you need a training tool alongside it.
Add Poplearn to Slack for that half. Free under 20 seats.
