What is Missive?
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.
What is Signal Desktop?
Signal Desktop's 8.35 beta returns to fix-only notes after contact sharing.
Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.35.0-beta.1 is another of those, following v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling, and v8.32.0-beta.1, which extended the unread filter into folders and search.
Missive vs Signal Desktop: editorial side-by-side
Missive
5.0COMMS
Native AI credits and a steady drip of MCP integrations turn Missive into a credible AI inbox.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Signal Desktop
5.0COMMS
Signal Desktop's 8.35 beta returns to fix-only notes after contact sharing.
◆ Current state
Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.35.0-beta.1 is another of those, following v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling, and v8.32.0-beta.1, which extended the unread filter into folders and search.
◆ Where it's heading
The desktop app is closing gaps with mobile one feature at a time, separated by maintenance betas. Visible features arrive about every two to three builds.
◆ Prediction
The next feature beta is likely within one or two builds, based on the cadence since October. The entries don't indicate what it will contain.
