What is Chatwoot?
Chatwoot added voice, then pointed its AI agent at the tickets it already resolved.
Chatwoot is an open-source customer engagement platform releasing every few weeks, and the window splits between two threads. One is channel coverage, where voice calls landed in June after years as the most-requested gap. The other is Captain, the built-in AI agent, which has been getting steadily less manual — document refresh in June, and in July the ability to mine resolved conversations for suggested FAQs.
What is Slack?
Slack's app platform is being rebuilt around agents, with the SDKs clearing old ground behind it.
Slack's developer changelog currently runs on two tracks. One is agent infrastructure: agent apps now receive context about whatever channel, DM, thread, canvas, or list the user has open when they message the app, and a new manifest-declared messaging experience defines how agents converse. The other is SDK maintenance at a steady clip — Bolt for JS v5, a batch of Node Slack SDK majors, and three CLI releases inside a month.

Chatwoot
2.5COMMS
Chatwoot added voice, then pointed its AI agent at the tickets it already resolved.
◆ Current state
Chatwoot is an open-source customer engagement platform releasing every few weeks, and the window splits between two threads. One is channel coverage, where voice calls landed in June after years as the most-requested gap. The other is Captain, the built-in AI agent, which has been getting steadily less manual — document refresh in June, and in July the ability to mine resolved conversations for suggested FAQs.
◆ Where it's heading
The company's own framing for voice is the tell: text channels first, voice only once the foundation was solid. With the channel set now complete, the remaining investment is in making Captain self-maintaining — its knowledge base updates itself and proposes its own content from support history rather than waiting to be fed. The help center work and the mobile AI Assist follow the same logic, putting existing capability everywhere the agent already is.
◆ Prediction
Expect the next release to extend Captain's use of resolved conversations, since both June and July releases moved in that direction. Voice is the more open question — a newly launched channel usually draws follow-up work, but nothing in these entries says what.
Slack
6.3COMMSCOLLAB
Slack's app platform is being rebuilt around agents, with the SDKs clearing old ground behind it.
◆ Current state
Slack's developer changelog currently runs on two tracks. One is agent infrastructure: agent apps now receive context about whatever channel, DM, thread, canvas, or list the user has open when they message the app, and a new manifest-declared messaging experience defines how agents converse. The other is SDK maintenance at a steady clip — Bolt for JS v5, a batch of Node Slack SDK majors, and three CLI releases inside a month.
◆ Where it's heading
The expansion is happening on the agent side while the SDK work removes rather than adds: axios swapped for native Fetch, Workflow Steps from Apps deleted, Node 20 set as the floor. Alongside that, a new Block Kit container block and the switch to pulling desktop notification text from blocks first both push more of the app experience into structured, app-rendered surfaces. Read together, Slack is moving the platform's center of gravity from configured workflow automation toward apps that hold a conversation with context.
◆ Prediction
Expect the next platform releases to widen what agents can receive and render — more context surfaces passed automatically and more Block Kit primitives to display results — while the CLI and SDKs keep their current maintenance cadence.
