Canary Mail brings real AI to your inbox - smart drafts, instant summaries, natural-language search, and on device triage - with privacy built into how it runs. Your email is never used to train generalized AI models. That is the difference between an AI that works for you and one that works on you.

Most AI email tools send everything to a vendor's cloud and, too often, use your messages to train theirmodels. That is the trade everyone else asks you to make.
Canary is built around two commitments instead. Your inbox intelligence - triage, prioritization, categorization -runs on your device. And for the features that do use cloud AI, like drafting and summaries, your email is neverused to train generalized AI models, and Canary has opted out of data-sharing for model training with thirdpartyproviders. Every message is protected with PGP encryption.
On-device inbox intelligence - triage and prioritization run locally and even work offline for mail you've alreadydownloaded.
Privacy-controlled cloud AI - drafts, summaries, and natural-language answers use hosted models, but yourcontent is never used to train generalized AI.
Works with the inbox you already have - Gmail, Outlook, iCloud, and IMAP. No new address, no migration.
There are three ways to get AI and privacy in email today. Canary is the one that pairs local inbox intelligence with a no-training commitment.
Proton and Tuta protect your privacy but can't do much inside your inbox - end-to-end encryption is exactly what stops their servers from reading and summarizing your mail. The cloud AI clients are powerful but run everything in their cloud and may train on your data. Canary keeps your inbox intelligence local, uses privacy controlledcloud AI for the rest, and never trains generalized models on your email.

Canary Mail AI does not limit your mailbox sync - all your emails remain accessible. However, AI suggestions depend on the context window: very long threads or emails beyond a certain size may not be fully included in AI analysis. AI results also vary depending on the thread context and your account type, so some features may behave differently across macOS, iOS, Windows, and Android.
No. In Canary's words: "Your data, including that from Google services, is not used to develop, improve, or train generalized/non-personalized AI and/or ML models." Canary has also opted out of data-sharing for model training with third-party AI providers.
Canary runs triage, prioritization, and inbox categorization on your device - they even work offline for mail you've already downloaded. Generative features like drafts and summaries use privacy-controlled cloud AI, with a firm commitment never to train generalized AI models on your email.
Canary is built for exactly this: on-device inbox intelligence, privacy-controlled cloud AI for drafting and summaries, PGP encryption, and a no-training commitment. Encrypted providers like Proton and Tuta are private but offer little inbox AI; cloud AI clients are capable but run everything in their cloud. Canary is designed to give you both.
Superhuman and Gemini run their AI in the cloud. Canary keeps your inbox intelligence - triage and indexing - on your device, uses privacy-controlled cloud AI for generative work, and never trains generalized models on your data.
Your inbox index is built and searched on your device. When you ask a natural-language question, the query and a limited set of locally selected results are sent to interpret and generate the answer - so the full index of your mail stays local rather than being stored on someone else's server.
On-device triage, categorization, and ordinary local inbox search work offline for mail you've already downloaded, and previously generated summaries remain available from your local cache. New summaries, AI drafts, and natural-language answers need a connection.
Yes - PGP / end-to-end encryption is a core pillar, not a buried setting, and it works alongside the AI features.
