Drive your whole workspace from the command line.

atbridge.ai has a local command line for Thunderbird, so scripts, cron jobs, CI and AI agents can read and act on your emails, calendars, contacts, notes & tasks. JSON in, JSON out — bring any model, keep it on your machine, and every direct operation runs ~20× faster and ~72% cheaper than a cloud mail tool.

What it is

atbridge is one binary — the command line for your whole atbridge.ai suite. Read, send, search and schedule your emails, calendars, contacts, notes & tasks straight from the terminal. Every command prints JSON by default, takes --pretty for a human-readable table, and --help for its flags.

$ atbridge mail list --limit 1
[{"id":"a1b2c3","from":"billing@acme.example","subject":"Invoice #1043","date":"2026-07-18T09:12:00Z","read":false}]

$ atbridge mail list --limit 1 --pretty
ID      FROM                  SUBJECT         DATE        READ
a1b2c3  billing@acme.example  Invoice #1043   2026-07-18  no

Same operations everywhere — the CLI, MCP and @bridge in Thunderbird all call the identical suite underneath.

Built for automation

Designed to live in a pipe and a crontab: predictable JSON, real exit codes, secrets over stdin.

Real workflows

A few lines of shell is usually all it takes. Every command below is a real atbridge verb.

# ~/cron/triage.sh — run nightly from crontab

# 1 · Archive read newsletters
atbridge mail search --from newsletter --until 2026-07-13 --snippet --limit 200 \
  | jq -r '.[].id' \
  | xargs -I{} atbridge mail move --ids {} --to Archive

# 2 · Forward this week's invoices to accounting
atbridge mail search --subject invoice --since 2026-07-13 --limit 50 \
  | jq -r '.[].id' \
  | xargs -I{} atbridge mail forward {} --from you@work.example --to accounts@work.example

# CI step — email the build report as branded HTML
atbridge mail send \
  --from ci@work.example --to team@work.example \
  --subject "Nightly report — build #$CI_RUN" \
  --md-file report.md

# Check the slot, then create a weekly series
atbridge calendar clash --start 2026-07-20T09:30:00Z --end 2026-07-20T09:45:00Z

atbridge calendar events create --title "Team standup" \
  --start 2026-07-20T09:30:00Z --end 2026-07-20T09:45:00Z \
  --recur "FREQ=WEEKLY;BYDAY=MO,TU,WE,TH,FR"

# Your briefing across emails and calendars
atbridge skill run today --pretty

Bring your own model — and your own compute

No lock-in on the intelligence. Bring an API key, or bring a coding CLI you already pay for.

printf '%s' "$ANTHROPIC_KEY" \
  | atbridge connect activate \
      --provider anthropic --key-stdin

atbridge connect activate --provider claude-cli
# or: --provider codex-cli

Either way the model is yours. atbridge.ai is one surface of the suite — it brings the tools; your client brings the intelligence. No model picker to babysit, no per-token cap from us.

Deterministic Skills

Some answers do not need a model at all. Skills read straight across your emails and calendars and print the answer instantly — with zero AI tokens.

$ atbridge skill list
$ atbridge skill run today --pretty

The same slash-commands you get in @bridge chat inside Thunderbird — here they are plain commands for scripts and cron.

Local, fast and cheap

The command line runs on your machine and answers locally, so there is no network hop and no full-HTML payload on every call. Point it at a local model and the whole loop stays on your machine; point it at a cloud model and only the specific text you ask about is sent to that provider — your messages are never routed through our servers.

Pricing

One atbridge.ai subscription is the whole productivity suite — emails, calendars, contacts, notes & tasks — across the CLI, MCP and @bridge inside Thunderbird; the CLI is just one way in. See the landing page and full pricing for the complete picture.

The CLI is on every plan, including Free — metered from one shared ops budget.
