What is Canary Mail?
Canary Mail ships maintenance across four platform lines; features have gone quiet since April.
Canary Mail publishes release notes per platform — Android, iOS, macOS and Windows each on their own version line — and every entry in the current top six is fixes only. The August wave put out iOS 5.22.0 and Mac 5.22.0 within a minute of each other carrying an identical changelog (Advanced View overwriting a custom SMTP username, plus crash fixes), with Android 3.99 alongside them fixing swipe-to-select misfires and PGP key handling. The most recent entries carrying a genuinely new capability are the April 5.19 releases, which let users dismiss unwanted compose suggestions.
What is Grain?
Grain reframes itself as the meeting layer for your AI, shipping a ChatGPT plugin and MCP tools.
Grain is a meeting-recording and notes product that has spent recent releases wiring itself into AI assistants. After adding one-click send-to-Claude/ChatGPT and an MCP server in the spring, it now ships as a full ChatGPT plugin with a broader MCP tool set and sharper auto-notes. The underlying capture stack (live notepad, meeting detection, clipping, uploads API) is mature.
Canary Mail vs Grain: editorial side-by-side
Canary Mail
5.0COMMS
Canary Mail ships maintenance across four platform lines; features have gone quiet since April.
◆ Current state
Canary Mail publishes release notes per platform — Android, iOS, macOS and Windows each on their own version line — and every entry in the current top six is fixes only. The August wave put out iOS 5.22.0 and Mac 5.22.0 within a minute of each other carrying an identical changelog (Advanced View overwriting a custom SMTP username, plus crash fixes), with Android 3.99 alongside them fixing swipe-to-select misfires and PGP key handling. The most recent entries carrying a genuinely new capability are the April 5.19 releases, which let users dismiss unwanted compose suggestions.
◆ Where it's heading
This is a mature client in upkeep rather than expansion: across four months of entries, the only line labelled New is a suggestion-dismissal control. Two defect threads recur across platforms — PGP correctness (a key-unavailable fallback on Android, a decryption failure on Windows) and Gmail account-setup crashes — which points at encryption and onboarding as where the real bugs live. iOS and macOS now ship in lockstep with word-for-word identical notes, so those two lines are converging in practice even though the version numbers stay separate.
◆ Prediction
After four consecutive maintenance waves the next release is most likely another cross-platform stability pass; these entries do not show enough to say when the PGP or compose surface gets new capability rather than repairs.
Grain
3.8COMMS
Grain reframes itself as the meeting layer for your AI, shipping a ChatGPT plugin and MCP tools.
◆ Current state
Grain is a meeting-recording and notes product that has spent recent releases wiring itself into AI assistants. After adding one-click send-to-Claude/ChatGPT and an MCP server in the spring, it now ships as a full ChatGPT plugin with a broader MCP tool set and sharper auto-notes. The underlying capture stack (live notepad, meeting detection, clipping, uploads API) is mature.
◆ Where it's heading
Grain is repositioning from a standalone recorder toward an interoperable context source that feeds meeting decisions and rationale into whatever AI tool a team already uses. Each release lowers the friction of getting meeting data out of Grain and into an assistant, betting that distribution inside ChatGPT and MCP clients matters more than owning the end-user surface.
◆ Prediction
Expect Grain to extend its plugin and MCP coverage to more assistants and deepen project-level context sharing, competing on how cleanly meeting data lands in AI tools rather than on the recorder UI itself.
