What is Kagi Search?
Expanding from a paid search engine into a privacy-first product family — Translate apps, Small Web platform, Maps.
Kagi is running a wide product surface in lockstep: Search continues weekly bug-fix and lens refinements (academic lens, slop reporting, location settings), Assistant has consolidated into Quick and Research modes with continuous model rotation, Translate has graduated to standalone iOS and Android apps with 248-language support and viral marketing moments (LinkedIn Speak), Small Web has reached 30,000 feeds with browser extensions and mobile apps, and Maps gained a Popular Areas data layer. The first Kagi Hub physical space opened in Belgrade.
What is Slack?
Slack is turning its app platform into an AI-agent surface — MCP on both ends, richer Block Kit.
The developer-facing changelog is busy and coherent: a Slackbot MCP client and expanded Slack MCP server tools, new Block Kit blocks (data visualization, data table, alert/card/carousel), streaming API updates for AI assistants, and a steady drumbeat of CLI and SDK releases.

Kagi Search
0.0COLLAB
Expanding from a paid search engine into a privacy-first product family — Translate apps, Small Web platform, Maps.
◆ Current state
Kagi is running a wide product surface in lockstep: Search continues weekly bug-fix and lens refinements (academic lens, slop reporting, location settings), Assistant has consolidated into Quick and Research modes with continuous model rotation, Translate has graduated to standalone iOS and Android apps with 248-language support and viral marketing moments (LinkedIn Speak), Small Web has reached 30,000 feeds with browser extensions and mobile apps, and Maps gained a Popular Areas data layer. The first Kagi Hub physical space opened in Belgrade.
◆ Where it's heading
Kagi is intentionally turning into a portfolio company — Search alone is no longer the product. Translate's mobile launch and viral moment, Small Web's app and extension push, the Hub physical space, and aggressive Specials partnerships (Windscribe, Addy.io, Notesnook, Ente, EasyOptOuts) suggest a deliberate strategy to be the brand for paying privacy-first internet users across categories. The cadence of bi-weekly changelogs surfacing dozens of community-reported issues suggests a healthy community-driven QA loop that few subscription competitors match.
◆ Prediction
Expect more standalone apps spun out of Kagi's product surface (Maps and News mobile likely next polish targets), additional Hub locations in 2026 to make the physical space a real channel, and continued partnership-stack growth via Specials. Watch for Small Web monetization or creator economics — the platform is large enough now to need a sustainability story.
Slack
6.3COMMSCOLLAB
Slack is turning its app platform into an AI-agent surface — MCP on both ends, richer Block Kit.
◆ Current state
The developer-facing changelog is busy and coherent: a Slackbot MCP client and expanded Slack MCP server tools, new Block Kit blocks (data visualization, data table, alert/card/carousel), streaming API updates for AI assistants, and a steady drumbeat of CLI and SDK releases.
◆ Where it's heading
Slack is positioning itself as both an MCP host (Slackbot calling external tools) and an MCP server (external agents acting in Slack), while Block Kit gains data-rich primitives and the streaming API matures for assistant experiences. The direction is making Slack a first-class surface for AI agents and data apps.
◆ Prediction
Expect deeper MCP capabilities and more data/visualization blocks, with continued frequent CLI/SDK releases supporting the agent-and-app platform push.
