How it works
Three steps from install to a calmer inbox—with an email spam classifier that never phones home.
02
Learn from your spam folder
On first setup, Inboxtune reads patterns from mail you already marked as spam—so new senders with the same shape get caught early.
03
Block and organize automatically
Spam is removed, senders are remembered, and your inbox management dashboard sorts everything into categories you control.
npx inboxtune init
Built for focus, not feeds
A full inbox management dashboard, local AI email assistant, and spam detection—without surrendering your mail to the cloud.
Spam detection
An on-device spam email blocker that scores messages locally—no uploads, no latency to a remote API.
Auto-block sender memory
When spam is deleted, the sender address is stored. Email them again and Inboxtune blocks unwanted emails before they land.
Smart categorization
Promotions, receipts, work, newsletters, personal—email categorization that matches how you actually read mail.
Custom categories
Add your own labels. The inbox cleaner adapts instead of forcing a generic taxonomy.
Learns from your behavior
Every correction tunes the local model. The more you use it, the sharper your AI spam filter becomes.
Plug-and-play
Works alongside Gmail, Outlook, and other clients—an email management tool for developers who live in the terminal.
Isolated per user
Your spam detection model and data stay on your disk. Self-hosted email filter semantics without running a mail server.
Email categorization you can touch
Click a category to filter the list—same as the real inbox organizer. Icons magnify gently as you move across them, like a dock.

Q3 planning sync
Your mail never leaves this machine.
Inboxtune runs an offline AI email filter entirely on your device. Classification, sender memory, and your inbox cleaner preferences stay in your user space—private by architecture, not by policy footnote.
Cloud spam filters vs. Inboxtune
When you want a Gmail spam filter alternative or Outlook spam filter upgrade without handing content to a remote AI spam filter.
| Typical cloud filter | Inboxtune | |
|---|---|---|
| Privacy | Mail often processed on vendor servers | Privacy-first email: everything stays on your machine |
| Ownership | Vendor controls models and retention | You own the offline AI email filter and its weights |
| Personalization | One-size rules for millions of users | Local AI email assistant trained on your spam folder and habits |
| Cost | Bundled or paid tiers with opaque limits | No-cloud email AI—run it as long as you want, no subscription |
Questions
Straight answers about the Inboxtune spam blocker, privacy, and your email client.
- Inboxtune is an Inboxtune spam blocker and email organizer that runs on your computer. It uses an offline model for spam detection, auto-block spam senders, and email categorization inside a full inbox management dashboard.
- No. Inboxtune is a local AI email assistant. Messages are classified on-device. Nothing is uploaded for scanning—this is on-device spam detection by design.
- When spam is removed, the sender address is saved. If they write again, Inboxtune blocks unwanted emails automatically—helping you stop spam emails permanently without manual rules.
- Yes. Inboxtune is a Gmail spam filter alternative and works with Outlook spam filter setups too—it plugs into your existing client rather than replacing it.
- Cloud filters send content to remote servers. Inboxtune is an offline AI email filter: your data never leaves your machine, and the email spam classifier improves from your feedback alone.
- No. Think of it as a self-hosted email filter for the intelligence layer only—you keep using Gmail, Fastmail, or Outlook while Inboxtune runs locally.
- On setup, Inboxtune studies messages you already marked spam to learn subject lines, domains, and patterns—so similar mail from new senders gets caught early.
- Yes. A tuning control lets you dial sensitivity—like adjusting an equalizer—so the spam email blocker matches how strict you want to be.
- Install is one command, which developers like—but anyone who wants a privacy-first email workflow and a calm inbox can use it.
- Models, sender block lists, and category preferences live in your user directory on your device. Each installation is fully isolated.
