NeuralMail: Open-source tool to search all your emails with LLMs

I got tired of “email archaeology”; digging through years of inboxes to find something I know is in there.

So I built NeuralMail: a fully open-source tool that makes your email (IMAP accounts) searchable with LLMs. It’s not an email client, just a way to extract and query info, no fuss.

Works with any IMAP provider (Gmail, Outlook, etc.), no lock-in.

Searches across multiple accounts at once

Handles 10k–100k+ emails, even attachments

Lets you plug in any LLM (local or API) so you can choose between privacy vs performance

Originally a weekend project (started CLI-only), but after a few months of use it’s become indispensable for me.

Would love feedback, bug reports, or ideas for integrations (Thunderbird/K-9 devs, looking at you, etc.).

Great work! Could this use a JMAP MCP to support FastMail?

Great idea; I just picked IMAP because I thought it'd be somewhat universal. I hadn't heard of JMAP before. It should be quite straightforward to integrate. FastMail actually also seems to support IMAP.
