Claap turns calls into promptable columns — and hands the whole table to your agent over MCP.
Claap is a meeting recorder that has spent this window becoming a structured data layer for revenue teams. AI Fields, shipped in July, lets a user write a prompt and get a typed column — a rating, a status, a text value — computed across every call in a meeting or deal view, auto-run on new calls and synced to the CRM. The month before, those same tables and columns were made readable by Claude and any other MCP client, and field enrichment gained deeper HubSpot targets. Around that core sit capture and reporting expansions: mobile apps for in-person meetings, automatic capture of contact email alongside calls, and Deal and Company reports built on the conversation record rather than the CRM stage.
SiYuan adds OAuth 2.1 to its built-in MCP server, opening the personal knowledge base to authenticated AI clients.
SiYuan is a locally-first personal knowledge management tool with a block-based document model, relational databases, mind maps, and a cloud sync layer. The 3.8.6 alpha cycle is deep in a feature-dense sprint: the top 8 entries are daily alpha builds, each layering new capabilities onto a 3.8.5 beta that shipped Anthropic Messages API support, database calendar and list views, and an editable mind map view for list blocks. The MCP server — introduced in an earlier cycle — now requires OAuth 2.1, making it a secure endpoint for external AI clients.

Around that core sit capture and reporting expansions: mobile apps for in-person meetings, automatic capture of contact email alongside calls, and Deal and Company reports built on the conversation record rather than the CRM stage.
The arc is unusually consistent — every release widens the input corpus or sharpens the output schema. Calls, then email, then in-person meetings recorded on a phone all flow into one deal timeline; on the other side, insights hardened into typed columns, then into user-defined prompted columns, then into something an external agent can read directly. That last move matters most: Claap is positioning as a source its customers' own AI reads, not only a dashboard people open, which is a different competitive posture than a call recorder that keeps its analysis inside its own UI. The feed also emits duplicate posts for several releases, so raw entry counts overstate the shipping cadence.
The next step suggested by these entries is writing rather than reading — AI Fields that trigger actions or CRM updates on a computed value, not just sync a column — since the prompt, the schedule and the CRM connection are all already in place.
SiYuan is a locally-first personal knowledge management tool with a block-based document model, relational databases, mind maps, and a cloud sync layer.

The MCP server — introduced in an earlier cycle — now requires OAuth 2.1, making it a secure endpoint for external AI clients.
SiYuan is building toward a position as an AI-augmented local knowledge base, not just a Notion alternative. Adding OAuth 2.1 to the MCP server, supporting the Anthropic Messages API, and accumulating calendar/list database views all point in the same direction: SiYuan as both a capture layer and a structured context source for AI workflows. Mobile improvements (pinch-to-zoom, Share Extension-equivalent inbox items, mobile command palette) suggest growing investment in mobile as a first-class editing surface.
A stable 3.8.6 release is imminent given the alpha cadence. The next directional move to watch is whether the MCP server gains broader capability exposure — currently it likely covers read/write access to notes, but richer query or database-level access would meaningfully expand what AI agents can do with a SiYuan workspace.
