Native AI credits and a steady drip of MCP integrations turn Missive into a credible AI inbox.
Missive is releasing on a roughly bi-weekly cadence, with most of the energy going into the AI assistant: tool-call introspection, native AI credits as an alternative to BYOK, MCP integrations with Todoist and ClickUp, and an Activity feed that lets the assistant analyze inbox/team-inbox/label state on demand. Calendar UX got drag-to-move and resize, Analytics gained inline time-series charts, and OpenAI EU residency support was added for European customers.
MirrorFly's feed is comparison-SEO listicles, not a product changelog
MirrorFly's tracked feed is pure SEO marketing — 'best alternatives to X' listicles, 'best video call API features' roundups, and ranked-tool comparisons that fold MirrorFly's CPaaS/IM/video SDK in among competitors. There are no product release notes in this window.

The product is methodically converging the team-inbox surface with an AI assistant that has actual context — not just a sidebar chatbot but one that can mention specific labels, fetch conversations, and reach into external task systems via MCP. The AI Credits launch is the strategic move; it ends the BYOK-only friction and starts building a new revenue line on inference markup. Continued MCP integration additions suggest more partner connections ahead.
Expect more MCP integrations (Linear, Asana, Notion are obvious next targets), AI Credit consumption analytics for admins, and likely a paid AI tier or assistant-only seat type once the credit usage data is in. Calendar will probably see more two-way sync polish given the drag-to-move foundation.

MirrorFly positions as a white-label communications SDK (chat, voice, video, AI agents), but the changelog surface here is keyword-targeted comparison content, so genuine product moves don't register as releases.
The feed will keep publishing alternatives-and-features SEO; real signal would require it to carry actual SDK release notes.
