Windows may warn you on first run. This release is not yet code-signed, so SmartScreen may show “Windows protected your PC”. Check the SHA-256 below first, then choose More info → Run anyway. Some antivirus products are also wary of the large, unsigned AI engine libraries the app bundles.
Released September 13, 2026. There is no automatic updater — by design, the app never checks for anything. A new version is one you choose to download. By downloading you agree to the license; please link people to this page rather than sharing copies, so the checksums below stay meaningful.
Before you install
What you’ll need
The app is the easy part. The AI model is a separate file you download once and keep wherever you like.
System
| Windows | Windows 10 or 11, 64-bit (x64) |
|---|---|
| Linux | x86-64, glibc 2.34 or newer (Ubuntu 22.04+, Debian 12+, Fedora 35+, RHEL 9+, Arch), X11 or Wayland with XWayland |
| Memory | At least 8 GB of RAM for a small (3–4B) model; 16 GB is comfortable for a 7–9B model. The app itself uses about 150 MB, but the model is held in system memory too, even when most of it runs on the graphics card: in testing, a 9B Q4_K_M model (a 5.6 GB file) used about 4.5 GB of RAM with 27 of its 32 layers on the GPU. The app shows you the fit before it loads. |
| Disk | About 270 MB for the app, plus your model file (typically 2–5 GB) |
| Network | None. The app runs fully offline. |
Graphics acceleration optional
| NVIDIA | Supported via Vulkan Tested |
|---|---|
| AMD | Supported via Vulkan Not yet tested |
| Intel Arc / iGPU | Supported via Vulkan Not yet tested |
| No GPU | Runs on the CPU — slower, fully functional |
AMD and Intel GPUs use exactly the same bundled Vulkan engine as NVIDIA, with nothing vendor-specific in between, but they haven’t been verified on real hardware yet. All you need is a current graphics driver. If a card isn’t picked up, the model runs on the processor instead.
An AI model (GGUF)
My Thought Safe doesn’t bundle a model. You supply a chat model in GGUF format — the same files LM Studio and llama.cpp use — and point the app at the folder. An instruction-tuned model of 7–9B parameters in a Q4_K_M quantization is a good starting point.
Optionally add a small GGUF embedding model for better memory search. Choosing a model →
Hardware security keys optional
Any FIDO2 key that supports the hmac-secret extension — YubiKey 5 series, SoloKeys, Nitrokey 3 and most modern keys — can unlock a vault alone or together with a passphrase.
Linux: install libfido2 (sudo apt install libfido2-1) and the udev rule described in the install guide. Windows needs nothing extra.
Checksums
Verify your download
Compare the SHA-256 of the file you downloaded against the value published here. A match means the file arrived intact and is the one the author published.
Windows (PowerShell)

A matching hash proves where the file came from, not what’s inside it — no hash can. That’s why the license explicitly permits you to take the app apart, and why the security page lists checks you can run on the app itself.
