ThreadMine is a Java thread dump analyzer with AI โ detects deadlocks, CPU spikes, pool exhaustion and virtual thread pinning. Free online, no signup.
Typer is a free AI chat app that runs entirely on your Mac. Everything stays on your device. No cloud, no account, no ads, no subscriptions.
How it works
Download Typer from the Mac App Store. On first launch, it detects your machine's specs and downloads the right AI model for your hardware. That's it. No setup, no configuration, no sign-up. Just open it and start chatting.
All AI processing happens locally on Apple Silicon using Metal GPU acceleration. Your conversations never leave your Mac. There's nothing to log into because there's no server.
What makes it different
Most AI chat tools require an internet connection and send your data to the cloud. Typer doesn't. It works completely offline. Take it on a plane, use it on the train, chat with AI anywhere.
Typer also includes local web search. It can search the web without sending your queries to external servers. No other local AI app offers this combination of offline AI chat and private web search.
Who it's for
Anyone with an Apple Silicon Mac (M1 or later) who wants AI chat without the complexity. You don't need to know anything about AI models or technical setup. Typer handles everything automatically.
It's also for people who are tired of running out of free tokens, seeing ads in their AI tools, or wondering what happens to their conversations. With Typer, the answer is simple: nothing leaves your Mac.
Always improving
Typer automatically updates its AI models as better ones become available. The app stays cutting edge without you having to do anything.
Completely free
No pricing tiers, no premium plan, no ads. Typer is free to download and free to use. That's not going to change.
ThreadMine.dev TyperTyper's answer:
In February 2026, ChatGPT started showing ads to free users and made $100 million in six weeks. That was the moment it became clear that free AI chat comes with a price - your attention, your data, or both. Typer started as a personal project: what if AI chat just ran on your Mac? No cloud, no account, no strings attached. Built solo over the past year with Tauri and Rust, designed to work the moment you open it. The goal was to make local AI as simple as opening any other app on your Mac. No terminal commands, no model configuration, no technical knowledge needed. Just ask your Mac anything.
Typer's answer:
Typer is the only AI chat app that combines fully local, on-device AI with private web search. Every other local AI tool is either completely offline or completely cloud-based. Typer bridges both - you get AI that runs on your Mac with zero internet required, but when you need it, web search works locally too without sending your queries to external servers. There's no account, no cloud, no ads, and no token limits. It auto-detects your Mac's specs and picks the right AI model for your hardware, so there's zero setup.

Typer's answer:
Mac users who want AI chat without the complexity. People who use ChatGPT but are tired of token limits, ads, and handing over their data. They don't care about model names or benchmarks - they just want to ask their Mac a question and get a good answer. Privacy-conscious users who don't want their conversations stored on someone else's server. People who travel or work offline and need AI that works without internet. Anyone with an Apple Silicon Mac who wants a simple, free, private AI assistant.

Typer's answer:
Typer is a free consumer app, not an enterprise product. It doesn't have "customers" in the traditional sense. Its users are individual Mac owners who want private, local AI chat without accounts or subscriptions.
