Who each one suits
Guru
- Companies that want one verified source of answers for staff and AI tools
- Support, sales and IT teams that need cited answers inside Slack or Teams
- Organizations that need audit trails and permission-aware AI answers
Stack Internal
- Engineering organizations grounding AI agents in their own verified knowledge
- Teams whose answers get buried in Slack or Microsoft Teams threads
- Groups of up to three people trying it on the free Starter plan
Worth knowing
Guru
- Guru publishes no prices: its pricing page describes custom packages scoped with the sales team, and the site offers no self-serve signup.
- Every invited user takes a paid seat, including people who only read content.
- There is no native mobile app; phones use a mobile web app or Slack, and Guru says its desktop experience has the most complete functionality.
- Canceling requires written notice at least 15 days before the renewal date, and Guru does not issue refunds.
Stack Internal
- Usage is metered in Flow Credits: a search or answer uses 1 credit and an update uses 3. Credits reset each usage period and unused ones do not roll over.
- The free Starter plan allows 3 collaborators and 1,000 credits a month, and leaves out SSO, audit logs and health and usage insights.
- The Organization plan has no published price: it is quoted by sales according to the number of credits needed.
- Connecting a Stack Overflow enterprise Q&A instance requires a Stack Internal Community Enterprise plan.
Key features
Guru
- Verified knowledge base
- Knowledge is organized into collections and kept current through verification. Usage signals, content age and policy rules handle most checks, and the rest are routed to assigned experts.
- Knowledge Agents
- Chat-style agents answer questions with citations, run multi-step research across sources and can act in connected systems, such as creating a ticket, as the signed-in user.
- Search across connected sources
- More than 100 connectors bring enterprise apps, databases and file systems into one search index, and each source keeps its original access permissions.
- AI-drafted documentation
- Agents turn conversations, meetings and tickets into draft documents and route them to subject-matter experts for review before anything is published.
- Answers inside other tools
- Guru answers questions in Slack and Microsoft Teams, in a browser extension for Chrome, Edge and Opera, and through an MCP server that AI tools can query.
- Governance controls
- Role-based access, SAML SSO and SCIM, audit logs with lineage, and DLP masking that redacts personal and sensitive data when content is ingested.
Stack Internal
- Automatic capture
- Connectors for Slack, Microsoft Teams, Google Docs and Stack Internal Community, plus a custom ingestion API, pull content in and break it into reusable units of knowledge.
- Trust engine and confidence labels
- Answers carry reviewer, recency and corroboration labels, and conflicting information is flagged, so a reader can tell when knowledge is reliable or needs validating.
- Expert validation
- Subject-matter experts are detected automatically and can also be managed by hand. Critical gaps trigger a validation workflow routed to them through Slack.
- Scopes and permissions
- Knowledge is organized into role-based Scopes so that people, teams and AI agents reach only what they should. Custom roles come with the Organization plan.
- Delivery to people and AI agents
- A chat interface, a REST API and an MCP server bring validated knowledge to people and to assistants and coding agents such as Claude and Cursor.
- Q&A, Articles and Collections
- The Community features keep Stack Overflow-style Q&A, long-form Articles, custom tags and curated Collections of related content.
