Your Own AI

Private AI on your machine. No one in control but you.

Your Own AI is a free desktop app for macOS, Windows, and Linux that runs AI models privately on your device. Your AIs, their personalities, their memories of you, and every conversation live on your machine - with an offline model, nothing you type ever leaves it. And because the app is open source, that claim is verifiable, not promised.

What it does

• Runs locally. Download open models (GGUF) from a curated catalog with hardware-fit guidance, and chat with no account and no internet after setup. GPU-accelerated out of the box (Vulkan on Linux and Windows, Metal on macOS), with an optional one-click CUDA engine for NVIDIA cards.
• Characters that are yours. Author AIs from 18 personalities with their own portraits, memories, and knowledge - then share them as single-file packs, cryptographically signed so anyone importing one can verify who made it. Eight free characters are on the characters page.
• Projects: agentic coding in chat. Open a folder and your AI reads files, proposes edits as diffs, and runs commands - asking permission for every action, with every step recorded. Powered by Your Own AI Build, a free add-on downloaded in one click.
• Documents, with proof. Attach files (scanned paper included, via on-device OCR) and check any answer claim-by-claim against the exact wording in the source with Verify sources.
• Memory you can read. A shared profile, each AI's own memory, and per-project memory - every entry visible, editable, and deletable. Nothing hidden.
• Records you can prove. Conversations are written into tamper-evident, cryptographically signed records (built on Holochain), private and encrypted on your device. Export any conversation, and optionally sign it with your Flowsta identity so anyone can verify it at flowsta.com.
• Backed up, recoverable. With a Flowsta Vault connected, everything backs up automatically - each conversation as its own compressed object, so no session is too large to protect - and restores to a new device.
• Smart routing, in plain language. Auto modes pick the right model per question by rules you can read: health questions stay on your device by policy, current events can use web search with cited sources, and every reply says which model answered and why. The mode name is the consent - "Auto - Offline Only" never touches the internet.
• Online when you want it. Frontier models and web search are available with a paid plan, through a relay that strips your identity and never stores or logs your messages. Never required, never default - and everything local stays free if you cancel.
• An engine for other apps. A local OpenAI-compatible endpoint serves your AIs - personality, memory, and records included - to editors, agent frameworks, and scripts. Or connect your own OpenAI-compatible server and its models join the picker.

Stack

• Tauri v2 (Rust backend)

Development

npm install
./download-llama-binaries.sh   # fetches the inference engine sidecars
npm run tauri dev

Building the full app also bundles Holochain sidecar binaries and pdfium; see .github/workflows/build-app-installers.yml for the complete recipe.
