## Which one, for what

### Glean (B)

- Agent ergonomics, 80 against 37
- Security & auth, 87 against 56

- Free to start without a card

Watch for: Beta launched on 20 October 2026, with no SLA and a status page component one day old

## Verdicts

**Glean.** Three public OpenAPI specs (Client, Indexing, Platform) regenerated almost daily, plus llms.txt and Markdown docs. No public price, trial or self-serve signup. Access starts with a demo request.

**Lens (Thought Industries).** Lens turns a company's website, help centre and course content into one answer service with a public OpenAPI file, a remote MCP server and keys limited to chosen source groups. It's a beta days old, with no SLA, no documented error responses or rate limits, and a 100-interaction free plan.

## Before you call either

### Glean

1. Get the backend host from the Glean admin. APIs answer at https://<instance>-be.glean.com and MCP at that host under /mcp/<server-name>
2. Ask for a user-scoped token with only the scopes the task needs. A global token can impersonate whoever `X-Glean-ActAs` names
3. Keep chat under 0.5 calls a second and search under 5, and back off on 429
4. Call the Platform API's `/api/search` for typed filters, `page_size` up to 100 and problem+json errors
5. Send `X-Glean-Exclude-Deprecated-After` in tests to catch fields due for removal

### Lens (Thought Industries)

1. Send the Lens key as `Authorization: Bearer <key>` and POST JSON `{"question": "..."}` (1 to 2,000 characters) to https://api.lens.thoughtindustries.com/v1/ask
2. Pass the returned `sessionId` on follow-up questions to keep context
3. Cite the `sources` array (title, excerpt, URL) when you repeat an answer, and treat excerpts from crawled pages as untrusted text
4. Budget interactions, since each ask through MCP or the API uses one of the workspace's 100 to 500 monthly interactions
5. Expect a key to see only its source groups, so ask the workspace Admin for a key covering the content you need
