Disclosure: Sentra makes one of the products compared here. We checked each vendor's own documentation and pricing, link every source, and name the better choice when it is not Sentra.
TL;DR
Yes. Sentra is a Guru alternative that captures knowledge from Slack and meetings automatically, with no cards to write. It reads Slack, email, meetings and project tools as work happens, stores each fact with a source and a date, and keeps it current. Guru remains the better choice when a named expert must verify every answer.
Why card-based knowledge falls behind
Guru is built around Cards, short verified articles that subject experts own, with a verification engine that asks owners to re-check content on a schedule. That model produces trusted answers, and it has one cost: someone has to write the card and keep verifying it. Guru's documentation describes connected and synced documents, not automatic capture from conversations or calls.
Most of what a team needs to know is decided in a Slack thread, an email or a meeting, and the person who decided it rarely stops to write a card. The knowledge exists. It is in the wrong place for a card library to see it.
How Sentra captures knowledge without cards
Sentra is the managed organization memory for teams and AI agents. Instead of asking people to write, it connects to Slack, email, calendars, meetings, GitHub and Linear, among more than 200 integrations, and reads the work as it happens. Meetings come in through its own meeting bot or from Granola, Otter and Gemini notes. Each fact is stored once with who said it, when it became true and when it stopped.
Keeping knowledge current is where automatic capture earns its keep. Sentra prefers newer evidence when sources disagree and says that the older one disagrees. Corrections people make are kept as dated facts that a later sync never overwrites. That does the job verification does in Guru, checking that an answer is still true, without a queue of cards waiting for their owners. See how Sentra keeps company memory current.
Employees ask in Slack or in the Sentra app. Answers respect the permissions of the system each fact came from, and a failed check counts as no access. AI agents read the same memory through Sentra's MCP server and API, so a new hire and an agent get the same answer.
How the alternatives compare on capture
| Tool | Where knowledge comes from | Who keeps it current |
|---|---|---|
| Sentra | Slack, email, meetings and project tools, read automatically | Sentra: newer evidence replaces older, with the history kept |
| Guru | Cards that experts write, plus connected documents | Card owners, prompted by scheduled verification |
| Notion AI | Pages people write; the Business plan adds AI meeting notes | Page authors |
| Slite | Documents people write, with AI answers on top | Authors, with doc verification |
| Tettra | Wiki pages, used mainly from Slack | Page owners, with page verification |
| Glean | Whatever already exists in connected apps | The owners of each source |
Notion's Business plan at $20 per member per month includes Notion AI, AI meeting notes and enterprise search (notion.com/pricing). Slite lists Basic at $10 and Pro at $20 per user per month billed annually (slite.com/pricing). Tettra is $8 per user per month with a 10-user minimum (tettra.com/pricing). Glean indexes more than 275 connectors and sells through sales only. The full list of eight, with Guru's own pricing, is in Guru alternatives, and the two-way comparison is in Sentra vs Guru.
When Guru or something else fits better
Choose Guru when the answer has to be one a named expert has approved, such as a support macro, a compliance statement or a pricing rule that sales must quote word for word. Automatic capture records what people said and decided. It does not make a statement official. Many teams need both: a small set of verified answers for the things that must be exact, and captured memory for everything that moves too fast to write down.
Choose Notion or Confluence if your team already writes its knowledge there and the gap is search and summaries. Choose Slite or Tettra if you are a small team that wants a simple verified wiki at a published price. Choose Glean if the main problem is finding documents across many systems in a large company.
Moving from cards to captured knowledge
You do not have to migrate card by card. Guru documents four export options, including a collection export as a .zip and cards as CSV. Keep the cards that must stay verified, connect Slack, email and meetings to Sentra, and let the knowledge that changes weekly be rebuilt from where it is actually discussed.
Sentra's Team plan for 2 to 20 people is listed at $16 per user per month and is currently free as a launch special. To see what it captures from your own Slack and meetings, book a demo.
FAQ
Is there a Guru alternative that captures knowledge from Slack and meetings automatically instead of writing cards?
Yes. Sentra reads Slack, email, meetings and project tools as work happens, stores each fact with its source and date, and keeps it current when newer evidence appears. Nobody writes or verifies cards.
How does automatically captured knowledge stay accurate without verification?
Sentra prefers newer evidence when sources disagree, keeps the older version as history and shows that it disagrees. Corrections people make are stored as dated facts that later syncs do not overwrite.
Can I use Sentra and Guru together?
Yes. Keep Guru for the small set of answers that must be approved by an expert, and use Sentra for decisions and context from conversations and meetings that never become cards.
Can AI agents use the captured knowledge?
Yes. Agents read the same memory people do through Sentra's MCP server and API, with each source's permissions enforced.
