AI Email Filter is a hosted email organizer that uses a large language model to sort incoming messages. You describe categories in everyday language, such as invoices from suppliers or newsletters you never read, and the service files each message accordingly. There is no filter syntax to learn.
The company positions the product as an addition to a mailbox rather than a mail provider or a replacement for spam protection. It targets categories that depend on meaning and variable wording, where native filters based on a fixed sender or subject tend to fall short. You keep reading mail in your usual email client.
Setup has three steps. You connect a Gmail or IMAP mailbox with supported credentials, which the site says are encrypted at rest. You then write category descriptions, optionally starting from a preset, and finally test them on a few emails before deciding when to turn on automatic sorting.
For each message, the classifier uses the sender, the subject and a limited body preview to choose one category. Explicit references and exclusions in your description help steer the decision. Saved sender categories can be reused for future messages and corrected when they are wrong.
The classifier can send that input to the configured language model. The hosted service still processes mail on its own server, even if you choose your own model endpoint.
Each category can chain several actions: move, flag, mark as read and forward. Forwarding can include an optional AI-written summary, with the original email attached, which suits newsletters and vendor updates that a team only needs in short form.
A history view lists completed actions. Recorded folder moves can be reversed while the message and its original folder remain accessible. The site is explicit that deletions are not automatically undone and forwarded copies cannot be recalled, so it advises starting with folder moves.
A stats dashboard shows volume, top senders and category breakdown. Guided setup walks through connecting a mailbox, choosing a preset and adjusting category prompts. You can also bring your own model through OpenAI, Ollama or any OpenAI-compatible endpoint.
