01 / Install

  1. 01
    Download the DMG

    Get the latest Fathom preview from the public GitHub release.

  2. 02
    Move Fathom to Applications

    Open the DMG and drag Fathom.app into /Applications.

02 / Choose a path

Recommended first

Explore the demo

Choose Explore the demo at launch. Fathom creates an isolated fictional financial world, so you can explore Inbox, Transactions, Purpose Accounts, Advisor, and Memory without touching your own data.

No Terminal or CLI setup required.

Alpha workflow

Use your own exports with Codex

Choose Open my Fathom or Start empty. For a fresh profile, let Codex use the embedded CLI to create or verify the physical Account and Source mapping before the first CSV import.

The CLI is an operator surface for Codex. It is not a human prerequisite.

03 / Give the CLI to Codex

No global PATH change required.

Open Codex and paste the prompt below. It uses the CLI bundled inside the installed app by its absolute path.

Use Fathom’s embedded CLI at:
/Applications/Fathom.app/Contents/Resources/bin/fathom

First run --help and --no-input paths --json.
Then help me set up a fresh Fathom profile for my bank CSV:
1. create or verify the physical Account,
2. create or verify the Source mapping,
3. test the CSV before importing,
4. explain every proposed mutation before executing it.

Do not guess Account IDs or import into an unverified profile.
Optional shell shortcut

You can use the absolute path directly. If you prefer a shortcut for the current shell session:

FATHOM="/Applications/Fathom.app/Contents/Resources/bin/fathom"
"$FATHOM" --help
"$FATHOM" --no-input paths --json
