How we grade them
| 3.2GPASliteVery good | 3.0GPAStack InternalVery good | |
|---|---|---|
| Value for money | BBasic is $10 a person a month billed yearly, a little under what's typical for this category. But the Slite Agent and search across your other tools need Pro at $20, and the monthly price isn't even on the pricing page. | BThere's no price to weigh. The only paid plan, Organization, is quoted by sales according to how many credits you need, and a B is where we put a tool whose paid side isn't published. It is metered, mind: a search or answer uses 1 credit and an update uses 3. |
| Free plan and trial | CNo free plan. You get a 14-day trial of the Basic and Pro features with no card needed, and after that you have to pay to keep using the workspace. A fair trial, but that's all there is. | BStarter is free and comes with the trust engine, 4 connectors and the ingestion API. But it stops at 3 collaborators and 1,000 credits a month, and unused credits don't roll over. Enough to try it, tight for a real team. |
| Features | AA real-time editor with templates and doc history, owners and verification for docs, and Ask, which answers questions with citations. Public docs, an API and an MCP server come with every plan. On Pro, an agent drafts fixes for out-of-date docs. | BDeep where it counts: answers carry reviewer, recency and corroboration labels, conflicts get flagged, and gaps are routed to your experts through Slack. The old Q&A, Articles and Collections are still here. But it captures from just four connectors, with an API for everything else. |
| Ease of use | BNo app store rating on record to go by. It's an app you sign up to and start writing in, and the trial asks for no card. Admins get a Knowledge Management Panel to review lots of docs in one go. | BNo rating on record to go by, so a B is as high as we go. It runs in the browser with nothing to install. You'll want Slack or Microsoft Teams connected before it earns its keep, and credits take a little getting used to. |
| Platforms and integrations | AWeb, Mac, Windows, iPhone, Android and a browser extension. It connects to Slack, Google Drive, GitHub, Linear and Jira, and the API and MCP server let Claude, ChatGPT or Cursor search, read and edit your docs. | BIt's a web app, with no desktop or phone apps listed. It connects to Slack, Microsoft Teams and Google Docs, and a REST API and an MCP server carry answers to assistants like Claude and Cursor. |

Worth knowing
Slite

- The pricing page shows yearly-billed prices only; a monthly plan exists, but its price is not published there.
- The Slite Agent, search across connected tools, OpenID SSO and custom domains for public docs need Pro at $20 per user / month.
- Basic limits each member to 30 AI questions and 30 AI edits a month, 5 GB of storage and 200 MB file uploads.
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.

Key features
Slite
- Collaborative editor
- A real-time editor with comments, mentions, custom templates, recurring scheduled docs and doc history. Docs can be exported as PDF, Markdown or HTML.
- Doc verification and ownership
- Each doc can have an owner and a verification status, and the Knowledge Management Panel lets admins review and act on many docs at once.
- Ask: AI search and answers
- Answers questions with cited sources. Basic searches Slite docs with 30 questions per member a month; Pro and Enterprise search connected tools with 100 per member.
- Slite Agent
- On Pro and Enterprise, an agent watches connected tools, drafts updates to out-of-date docs and routes them to a person for approval. It draws on pooled credits, 50 per seat a month.
- MCP and public API
- Every plan includes a public API and an MCP server, so assistants such as Claude, ChatGPT and Cursor can search, read and edit docs under the user's permissions.
- Public docs
- Docs can be shared publicly on every plan, with AI answers for readers. Search-engine indexing, custom branding and a custom domain for public docs start on Pro.
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.
