✦ Our Story

We got tired of
big tech reading our emails.

So we built an email client where the AI lives on your computer - not in someone else's data center.

Your email is the most sensitive data you have. More than your photos. More than your messages. Every business deal, every personal conversation, every secret - it flows through your inbox.

When we looked at the email client landscape, we saw the same pattern everywhere: companies offering "AI features" by shipping your private email data to OpenAI, Google, or Microsoft's cloud. They call it a feature. We call it a breach of trust.

The alternative - Superhuman ($30/mo), HEY, Fastmail - still don't give you real on-device AI. Apple Mail looks good but has zero intelligence. Gmail is free because you're the product.

We asked ourselves: what if you could have a genuinely smart email client that never touches the cloud? No data harvesting. No cloud API keys. Just a fast, local AI model running right on your machine - at a price that won't make you cry.

TurboMail exists because AI shouldn't cost you your privacy.
The build

Built with the
right stack.

Every technology choice was made to maximize privacy, performance, and user control. We avoided anything that required external dependencies for core features.

⚡

Electron + React

The frontend is a TypeScript React app with Tailwind CSS, running inside Electron. Native-feeling UI, real window chrome, system tray integration.

Python FastAPI Backend

A local FastAPI server handles email sync, OAuth, database, and AI inference. Bundled with PyInstaller so no Python install required by users.

HuggingFace Transformers

Models run via HuggingFace Transformers + PyTorch with bitsandbytes quantization. Supports Apple MPS, NVIDIA CUDA, and CPU fallback.

The journey

From idea to shipping.

Phase 0 → Idea
Got frustrated reading about AI email features sending data to the cloud
We were using Gmail's Smart Reply and realized: Google just read our entire inbox to generate that suggestion. That felt wrong.
Phase 1 → Foundation
Electron + Python spine, working health check
Got the desktop app scaffolding working: Electron spawning a Python FastAPI server, React connecting to it, proving the architecture was viable.
Phase 2-3 → Real Emails
Gmail OAuth, IMAP, email sync, HTML rendering
Connected real email accounts, synced actual inboxes, tackled the gnarly problem of rendering HTML emails safely (DOMPurify + sandboxed iframes).
Phase 4-6 → The AI
Local LLM, insights, chat, actions
Integrated HuggingFace Transformers, built the model setup wizard, wired streaming chat, and taught the AI to draft replies and schedule meetings.
Phase 7-8 → Shipped
Calendar, web search, TTS, packaged + distributed
Rounded out the feature set with calendar sync, AI web search, listen mode, and packaged the whole thing into signed .dmg and .exe installers.
What we stand for

Our values ship with the app.

🔒

Privacy is non-negotiable

We don't collect analytics. We don't have a server that knows who you are. We can't read your emails because they never come to us.

💸

Priced for humans

Starts at $0.99/mo for students. $2.99/mo for individuals. Competitors charge $30. We charge 90% less. Smart email shouldn't cost a fortune.

⚡

Speed without compromise

Local AI means no network latency for intelligence features. Your inbox loads fast, your insights load fast, and it all works offline.

🔍

Radical transparency

Clear docs on what runs where. We don't collect analytics. We don't know who you are. You can inspect every network call and find nothing going to our servers.

🎯

Built for power users

We don't dumb things down. If you want to run a 70B model locally, configure custom IMAP settings, or inspect the AI's reasoning - you can.

🌱

Built to last

No VC pressure to monetize. We're building something we use ourselves every day - and that means we care about keeping it great long-term.
