Trilium Notes vs Slack
A side-by-side editorial comparison of Trilium Notes and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Trilium Notes vs Slack: at a glance
What is Trilium Notes?
Trilium adds spreadsheets and OCR while deliberately ripping out its LLM integration
Trilium Notes is on a steady minor cadence under its post-handover maintainership. The current arc is striking for cutting against the grain: 0.103 introduces new note types (spreadsheet) and OCR, while 0.102 removed the built-in LLM integration outright and shipped urgent security fixes.
What is Slack?
Slack's developer platform is reorganizing around agents, MCP, and streaming Block Kit surfaces.
Slack's platform work over the past quarter centers on agent development and richer app surfaces. The CLI 4.x line ships agent scaffolding, the Slack MCP server keeps gaining tools, and Block Kit has added streaming APIs plus new block types (cards, carousels, data tables). Security plumbing like PKCE and optional OAuth scopes rounds out a platform being hardened for third-party AI apps.

Trilium adds spreadsheets and OCR while deliberately ripping out its LLM integration
◆ Current state
Trilium Notes is on a steady minor cadence under its post-handover maintainership. The current arc is striking for cutting against the grain: 0.103 introduces new note types (spreadsheet) and OCR, while 0.102 removed the built-in LLM integration outright and shipped urgent security fixes.
◆ Where it's heading
The direction is a focused, locally-grounded knowledge tool — adding structured data (spreadsheets) and document capture (OCR) while shedding hard-to-maintain AI features. Trilium is optimizing for a maintainable, privacy-respecting core rather than chasing AI parity.
◆ Prediction
Expect continued capability depth in note types and capture (spreadsheet, OCR) with AI staying out of core, and security responsiveness remaining a priority.

Slack's developer platform is reorganizing around agents, MCP, and streaming Block Kit surfaces.
◆ Current state
Slack's platform work over the past quarter centers on agent development and richer app surfaces. The CLI 4.x line ships agent scaffolding, the Slack MCP server keeps gaining tools, and Block Kit has added streaming APIs plus new block types (cards, carousels, data tables). Security plumbing like PKCE and optional OAuth scopes rounds out a platform being hardened for third-party AI apps.
◆ Where it's heading
The direction is to make Slack the surface where AI agents are built, deployed, and rendered. Streaming APIs and new Block Kit blocks exist to host conversational and agent UIs natively, while the MCP server turns Slack into an addressable tool for external agents. Expect continued cadence on both the developer tooling and the runtime surface.
◆ Prediction
Next likely moves are more MCP server tools and additional streaming-oriented Block Kit components as the agent-app surface matures.
