Your email history, mapped.
Axiom reads the mail you already have — Thunderbird, Apple Mail, Maildir, IMAP — on your own computer, and turns twenty years of it into a living map of the people, projects, places and epochs of your life. Every insight points back to the messages it came from.
Search finds a message. Axiom finds the story.
Search across decades
Every account, every client, every year in one index — with filters for people, dates, folders, attachments and files.
People, resolved
Three addresses become one person. See how much you talk, in which direction, how fast either side replies, and how it changed.
Epochs and places
The chapters of your life, detected from who you wrote to — and where you were based, inferred from your own mail.
Open loops
Questions nobody answered and promises that slipped — the replies you owe and the ones owed to you.
Reports and digests
A dossier for any person, a digest for any week: who was active, what got busy, who went quiet.
Ask your assistant
Axiom speaks MCP, so Claude, ChatGPT or a local model can answer questions about your history — from where you already work.
Point it at the mail you already have.
Reads in place, never writes
Axiom finds your Thunderbird or Apple Mail profile, your Maildir or mbox archives, and reads them read-only. Your mail client won't notice it's there. Documents, notes, contacts and calendars on disk join the same map.
Builds the map
Threads, people, relationships, epochs, places and open loops — in minutes for a 100,000-message archive, on a 2018 laptop with no GPU. Everything stays on your disk.
Answers with receipts
Browse it in the app, follow it live as new mail arrives, or ask an assistant. Every claim links to the messages behind it; anything it can't back up is flagged.
Built for reading years, not inboxes.
Promises, not a policy.
The app works offline. Nothing is sent anywhere unless you turn on an assistant — and then names and addresses are redacted first, and you can see exactly what went out.
Read-only, in place. It cannot delete, move, mark or send anything.
Every generated statement cites the messages it came from. Uncited claims are flagged, not hidden.
A metadata-only mode never indexes message bodies at all — just who, when and how often — and still draws the map.
Institutional memory for the whole team.
The same engine runs as a self-hosted server with a web interface for a lab, an agency or a firm — shared correspondents, per-source access, audit trails, and a metadata-only policy where content analysis isn't an option. A cloud edition with SSO and data residency follows. Talk to us about a pilot.
Free on your machine. Pay only for what runs elsewhere.
