What each week held
Read in 3 of the last 12 weeks. The other 9 were not read at all, and are drawn empty rather than as quiet.
The bar is observed claims in that week. A dashed marker is a week this company was not read at all — not a quiet one. Inferences and failed reads are in neither.
What it declares
- AI Agent (Notion Agent)
- Custom Agents
- Docs and wikis
- Databases and project tracking
- AI Meeting Notes
- Developer Platform (API, Workers, MCP)
- AI Connectors (Gmail/Outlook)
- Enterprise search
As the company’s own pages describe it. Forge did not test any of these.
What users raised
- AI add-on removal forces Business-tier upgrade for solo AI users
- Notion Mail wind-down disrupts standalone email workflow
- Custom Agent credit metering adds unpredictable cost
- API breaking changes require migration work before Sept 30, 2026 deadline
Themes people raised in public. A complaint is somebody’s opinion, not a measurement of the product.
Everything on record
14 observed claims. Newest first; the tag on each row is what kind of claim you are reading.
- PRODUCTFACTSep 28, 2026
Notion's File Upload API expanded to accept CAD and 3D model formats (DWG, DXF, RVT, STEP, STL, OBJ, GLB, etc.), attaching them to pages as file blocks, alongside improved MIME-type resolution for generic octet-stream uploads.
Broadens Notion's use as a hub for engineering/design file context, relevant to technical teams
releasebot.io/updates/notion - PRODUCTFACTSep 28, 2026
Notion's API now validates custom_emoji icons on pages, databases, data sources, and callouts, requiring the emoji to exist in the integration's workspace or returning a validation_error instead of silently saving a null icon.
Minor API integrity fix affecting integrators setting custom emoji icons programmatically
github.com/ramnes/notion-sdk-py/issues/404 - PRODUCTFACTSep 28, 2026
Notion's REST API added new rate-limit handling: 429/529 responses now echo Retry-After in the body as additional_data.retry_after, added two new rate_limit_reason values distinguishing endpoint-level vs. blocked-connection limits, and workspace-limit errors now note the limit is shared across all connections.
Affects integrators building on the API, especially MCP clients that cannot read HTTP headers
developers.notion.com/page/changelog - PRODUCTFACTSep 28, 2026
Notion completed the Notion Mail wind-down on the previously announced September 22, 2026 date; the standalone inbox is now retired on web, desktop, and iOS.
Confirms execution (not just plan) — Notion Mail users must now rely on Connectors/agents for email context
matthiasfrank.de/en/notion-updates/ - PRODUCTFACTSep 28, 2026
Notion's Personal Agent gained the same Effort setting previously added to Custom Agents, letting users control how much reasoning the model spends on a request, with available levels varying by model (e.g. GPT-5.6 Sol offers No thinking, Low, Medium, High, xHigh, Max).
Affects users tuning cost/latency vs. reasoning depth across both agent types, not just Custom Agents
matthiasfrank.de/en/notion-updates/ - PRODUCTFACTSep 13, 2026
Notion's REST API now enforces the existing Free workspace block limit for internal and OAuth connections restricted to selected workspaces, described as not a new limit but new enforcement.
Free-tier integrators building via API may now hit block limits they previously bypassed.
releasebot.io/updates/notion - PRODUCTFACTSep 13, 2026
Notion Developers launched Notion Agent APIs in public beta, adding session-based chat, streamed replies, action submission, event history, and programmatic Custom Agent management, with upgrade guidance for teams moving off the private alpha routes.
Developers building on Notion's platform gain a stable API surface for agents ahead of the alpha deprecation deadline already noted in the ledger.
releasebot.io/updates/notion - PRODUCTFACTSep 13, 2026
Notion shipped an agent 'suggest edits' mode (Aug 28, 2026) where agents propose line-level changes for approval rather than making direct edits.
Minor UX refinement to existing agent feature, not a new capability tier or pricing change.
www.notion.com/releases - PRODUCTFACTSep 13, 2026
Notion added model controls (Sept 9, 2026) letting workspace owners choose which AI models are available separately for Notion Agent and Custom Agents, and set a default model for Custom Agents; this is available on Business and Enterprise plans.
Admins on Business/Enterprise get governance over AI model spend and compliance, extending the AI packaging story already gated to those tiers.
www.notion.com/releases - PRODUCTFACTSep 6, 2026
Notion released API version 2026-03-11 with breaking changes (after→position, archived→in_trash, transcription block renamed to meeting_notes), requiring integrators to migrate off alpha agent/thread routes by September 30, 2026.
Affects third-party integrations and API consumers who must update code before the migration deadline.
developers.notion.com/page/changelog - PRODUCTFACTSep 6, 2026
Notion's developer platform split its MCP search tool into a keyword-only notion-search and a separate semantic notion-ai-search, and added a Developer section for managing Workers, connections, and API tokens with one-click ID copying.
Affects developers/integrators building on the Notion API/MCP who need to update tool usage and adopt the new Developer section.
releasebot.io/updates/notion - PRODUCTFACTSep 6, 2026
Notion is winding down the standalone Notion Mail inbox (web, desktop, iOS) on September 22, 2026, shifting effort toward getting email into Notion as context via Gmail/Outlook AI Connectors and email automation agents rather than a dedicated mail client.
Affects users relying on Notion Mail as a primary inbox; they must migrate to connectors/agents or another email client before the shutdown.
matthiasfrank.de/en/notion-updates/ - PRICINGUSER OPINIONSep 6, 2026
The standalone Notion AI add-on (previously ~$10/member/month) was eliminated and full AI access (AI Agents, Ask Notion) now requires the Business plan, meaning solo users seeking AI must pay Business-tier pricing rather than adding AI to Free/Plus.
Affects individual/solo buyers who previously could add AI cheaply to lower tiers; now forces upgrade to Business for full AI.
get-alfred.ai/blog/notion-pricing - PRICINGCOMPANY CLAIMSep 6, 2026
Notion charges $0 for Free, $10/user/month (annual) for Plus, $20/user/month (annual) for Business, and custom pricing for Enterprise; monthly billing runs higher per seat.
Sets the baseline per-seat pricing ladder buyers compare against.
