@bridge AI Chat

Open the @bridge AI Chat right inside Thunderbird, pick the AI of your choice — any provider, or a private local model — and work every mailbox at once: triage, summarise, draft and ask across all your accounts. Skills (/from, /today, /clashes) answer instantly with no AI tokens spent, and Fast Actions turn any reply into a note or an email draft in one click.

In Thunderbird

@bridge Email Compose

Write with AI right in the Thunderbird compose window: turn a rough draft into a polished message, or turn the figures in your draft into a branded HTML email with a real chart — on your saved theme, in one click.

atbridge @bridge Notes: an open note is attached to the docked AI Chat via Use as Context; the AI returns an improved launch plan, and Save to Notes appends it back into the note.
@bridge Notes ↔ AI Chat — open a note, Use as Context, ask the AI to improve it, then Save to Notes appends the reply straight into your note. Your local, AI-native markdown workspace.

@bridge Notes

@bridge Notes is a local, AI-native markdown workspace built into Thunderbird: keep folders of .md notes in a real editor with a docked AI Chat. Use as Context hands the open note to the AI; ask it to improve or extend the note, then Save to Notes appends the reply straight back in. Everything stays on your machine.

atbridge in Thunderbird: the Fast Actions menu on an open email saves it to @bridge Notes as a clean markdown note in one click.
Fast Actions — turn the open email into a note in one click: To Note saves it to @bridge Notes as clean, source-linked markdown. No copy-paste.
atbridge in Thunderbird: Fast Actions extracts the action items from an open email into a checklist, then creates them as Thunderbird tasks in one click.
Fast ActionsExtract action items reads the open email and turns each step into a task; review the list, then Create tasks drops them straight into Thunderbird.
In Thunderbird

@bridge Fast Actions

One click on an open email or note fans it out across the suite — To Note, Extract action items → Tasks, To Calendar Event, To Contact. Fast Actions interconnect your emails, notes, tasks, calendars and contacts, so nothing needs copy-paste.

atbridge in Cursor (MCP): the assistant composes a branded progress-report email and opens it in Thunderbird.
Drive atbridge from Cursor — or any MCP client — and have it compose a branded email straight into Thunderbird.
atbridge in VS Code: the Claude Code agent runs atbridge CLI commands (visible call logs) to find this week's unanswered client emails, then answers in plain language.
Ask in plain language in VS Code — the agent runs the atbridge CLI (you watch the commands run) and answers in plain language: which clients are still waiting on a reply.
For developers

From your IDE

In VS Code, Cursor, Claude Code — or any IDE that speaks MCP (or runs the CLI)? Drive atbridge from your editor: have your agent compose a branded email and open it in Thunderbird, without leaving your code.

atbridge in Claude Desktop (MCP): the assistant reads delivery-progress emails via atbridge and summarises how much of the work is done.
Ask Claude Desktop in plain language — it works your inbox through atbridge (MCP), running locally on your machine. atbridge never routes your mail through its own servers.
Claude Desktop runs a user's own 'Daily agenda' skill that calls atbridge over MCP to fold unread mail and today's calendar into a morning brief.
Run your own Claude skill: a “Daily agenda” skill calls atbridge (MCP) to fold unread mail + today's calendar into one morning brief — clashes flagged. Build a skill once, run it daily.
For AI power users

AI agent desktop clients

Ask Claude Desktop — or any agent that speaks MCP locally — in plain language. It reads and works your inbox through atbridge, running on your machine; your mail is never routed through our servers.

atbridge from a terminal: CLI commands search mail across accounts, show a message, and forward it — output as plain text or JSON.
Drive atbridge from any CLI — your shell, a script, cron or CI: search, read, forward and schedule mail, with JSON output to pipe anywhere.
A terminal shows a user's shell script and cron job driving atbridge to archive newsletters and forward invoices automatically.
Your own script drives atbridge — a cron job archives newsletters and forwards invoices every morning. JSON in, JSON out; pipe it through jq, xargs, anything.
For builders & automation

From the command line

Any tool that can run a command drives atbridge — your shell, a script, cron, or CI. Search, read, send, forward and schedule mail; JSON in, JSON out, pipe it anywhere. The email primitive your agent stack was missing.

On every plan

@bridge Notes: your private, local, AI-native workspace.

A real notes app inside Thunderbird — Markdown, Mermaid diagrams, LaTeX, and audio notes — that stands on its own and talks to the AI you choose. A private, linked-notes markdown workspace, on your machine, that also happens to know your inbox.

  • Write anything. A WYSIWYG editor with a raw-Markdown escape hatch — plus Mermaid diagrams, LaTeX math, inline charts, and audio notes with transcription.
  • Link your thinking. Connect notes with [[links]] that open the target; copy a portable link to any note and paste it anywhere.
  • Hand a note to the AI. Plug a note as live context so every reply builds on it, or capture chat straight into a note with the Note Overlay.
  • Yours, offline, no lock-in. Plain .md files on your own machine — a workspace you own, not a silo you rent.

A standalone workspace even on Free (basic editor); the full editor — auto-save, audio transcription, rich chart editing, the docked chat — comes with Personal and Pro.

The full mailbox — not a read-only summary.

Emails, calendars, and contacts — your AI gets the same read and write powers you have, not a one-way digest.

✉️ Mail, end to end

Read, send, reply, forward, search, move, delete, and tag across every account. Compose in plain text, HTML, or Markdown.

📅 Calendar & scheduling

Create, update, and delete events across your calendars — with cross-calendar clash detection so your AI never double-books you.

👥 Contacts & address book

Search, create, and update contacts across every address book Thunderbird holds — so "email Maya" just works.

🔒 Local-first

The bridge runs on your machine, listening only on 127.0.0.1 — your mail is never routed through atbridge.ai's servers. A direct action runs locally in ~5 ms — about 20× faster than a cloud round-trip — and ~72% lighter on tokens (≈3.5× cheaper per fetch) than a cloud bridge.

🔌 Your LLM, your choice

Activate any LLM (large language model) provider right in the Thunderbird extension — OpenAI, Anthropic, Gemini, Mistral, Groq, OpenRouter, NVIDIA and more, or local Ollama. Pick a provider and model in the @bridge panel; your API key is encrypted on-device, sealed by your OS keychain. Or run the model locally with Ollama — private, on-machine AI.

🖥️ Any surface

Drive atbridge.ai from wherever you work: the @bridge panel inside Thunderbird, an IDE (Cursor, VS Code, JetBrains, Antigravity), Claude Desktop or any MCP agent, Claude Code, or the terminal — same ops everywhere.

🌐 Any provider

Anything Thunderbird supports: Gmail, Outlook, iCloud, ProtonMail Bridge, FastMail, your company IMAP.

💸 Cheaper to run

Replies are lean and text-first, so your model processes a fraction of the tokens per task — the LLM bill you already pay drops. (atbridge.ai plans & quotas are separate — see pricing.)

🛠️ Built for builders

A CLI, JSON I/O, stable schemas, and a built-in MCP server. Drop it into your scripts or agent framework in one command.

Pro

@bridge Branded Email: your brand, every email, zero design work.

Ask your AI for an announcement, a digest, a personal note — get a fully-styled HTML email with your brand colours, your fonts, your signature. Opens in Thunderbird compose for your review before you send.

  • Your AI writes the message, @bridge renders the design. The LLM focuses on what to say — content, tone, structure. @bridge Branded Email handles the layout, colours, and email-safe HTML. No tokens wasted on CSS tables that render inconsistently across mail providers.
  • Brand themes baked in. Default to the @bridge theme, override with your own colours + fonts.
  • Battle-tested email components — including charts. Headings, text, buttons, images, and Chart blocks (bar, line, area, stacked bar/line, scatter, bubble, pie, doughnut, polar area, radar). Chart rendering runs 100% locally — no data is sent out to render them. Every block renders correctly across major mail apps and webmail UIs without burning LLM tokens on layout.
  • Opens in Thunderbird compose for your review before send. No accidents.

Included on Pro (unlimited) and Personal (10 branded drafts / month).

Simple pricing. Local always.

Questions

What can I do with atbridge.ai?

Just say what you need in plain language. A few ideas to try:

Triage my inbox.
atbridge.aiArchives the newsletters and receipts, flags the few emails that actually need a reply, marks the rest read.
Draft replies to everyone still waiting on me.
atbridge.aiFinds unanswered threads from the past week and writes a contextual reply to each — saved as drafts for you to review and send.
Send the Q3 report to the board.
atbridge.aiTurns your Markdown into a clean, formatted HTML email and sends it to the whole board list — signature and all.
Find the invoice from March and forward it to accounting.
atbridge.aiSearches every connected account, finds the right message, and forwards it with a short note.
Summarize what I missed this week.
atbridge.aiReads unread mail across all your inboxes and hands back one paragraph — who needs what, and by when.
Reply to Sara: yes to Friday at 3.
atbridge.aiOpens the thread, writes the reply in your voice, and sends it — or saves it as a draft for you to send.

That's a taste — anything you can describe across your emails, calendars and contacts is fair game. Browse the docs for the full picture →

Does my email leave my machine?

No. atbridge.ai runs as a local process. Your AI talks to it over a localhost socket — not the public internet. We don't operate servers that touch your email. The only thing our servers do is verify your subscription.

Is atbridge.ai faster and cheaper than a cloud Gmail MCP?

Yes, measurably. Because atbridge.ai runs locally, a direct operation — reading a message, listing folders — completes in single-digit milliseconds: about 20× faster than the network round-trip a cloud tool pays before it even starts work. And because it returns plain text instead of full HTML by default, a typical fetch uses about 72% fewer tokens (~3.5× cheaper) with no unsolicited HTML. (Full-text search is a local scan, so we scope the speed claim to direct operations.)

What counts as an "operation"?

One operation = one action that fetches or changes mail: a search, a list, a send, a reply, a forward, a move, a delete, a contact create/update. Follow-ups that don't fetch new data — opening a message you just listed, reading a thread you already pulled, viewing a contact you searched — do not count. Plan and bridge meta-commands never count.

Is VAT included in the price?

No — the prices shown are exclusive of VAT. VAT is calculated and added at checkout based on your billing country. EU buyers will see their applicable rate applied automatically by Stripe. You'll see the final amount including VAT before completing payment.

What happens when my 14-day Free trial ends?

You keep CLI access and 20 operations per month, forever. You lose MCP (so AI agents can no longer call you directly — but the CLI still works). Outbound mail gets a small "Sent with @bridge" footer. Upgrade anytime to remove both.

What does the early-bird price get me?

If you subscribe before Nov 1, 2026, you lock in €4.99 (Personal) or €9.99 (Pro) per month — forever. Stripe never auto-migrates subscribers to a new price, so as long as your subscription stays active, your monthly cost never changes. After Nov 1, the same plans cost €7.99 and €14.99 for new subscribers.

Can I pay annually?

Yes — annual billing opens on Nov 1, 2026 (when the early-bird window ends). Annual works out to two months free vs. paying monthly. Early-bird subscribers stay on monthly billing — the held while subscribed monthly rate is already the best deal we offer.

Do I need to be technical to use it?

To install, you run one setup command — about five minutes, with step-by-step instructions. After that you just talk to your AI assistant in plain language. No coding required to use it day to day.

Which AI tools work with it?

Anything that can run a command or speak MCP: Claude Desktop, Claude Code, Cursor, Cline, Aider, Ollama, or your own agent. If it can run a shell command, it works.

Can I use a fully local LLM?

Yes. Run atbridge.ai with Ollama and a local model — Qwen2.5-14b-instruct, Llama 3, Mistral and others work well. Your AI runs on your machine, so no email content goes to any AI provider — zero cloud AI, zero API keys. (Sending mail still uses your normal mail server, as always.) The trade-off is inference speed — it depends on your hardware. A modern Apple Silicon Mac or a fast GPU makes it practical for everyday use. This is the maximum-privacy configuration.

Why Thunderbird?

Our goal is to bring local AI email to as many people as possible, and Thunderbird gives us the widest reach to start: it's free, runs on every platform, works with any inbox via IMAP, and is the only mature email client that's genuinely extensible via open WebExtension APIs. That means one integration, any provider — Gmail, Outlook, iCloud, IMAP — for every user. We're always thinking about how to reach more people.

What does "device" mean?

One machine you've activated your plan on. Free covers 1, Personal covers 2 (e.g. laptop + desktop), Pro covers 5. You can move your plan between machines from your account.

Does my AI send email without asking me?

That's up to you. You can have it save everything as drafts for review, or let it send directly. Write access for agents is off by default and you opt in explicitly.

Can I cancel?

Yes, anytime, from the Stripe customer portal linked in your account. Your plan stays active until the end of the billing period.

Stop doing email by hand.

Give your AI assistant the keys to your inbox — locally, privately, and faster than any cloud bridge.
