# Your Own AI > Your Own AI is a free, open-source (AGPL) desktop app by Flowsta that > runs AI models privately on the user's machine (macOS, Windows, Linux). > Offline models keep every conversation on-device; optional paid plans > add online frontier models through a relay that strips user identity > and never stores or logs message content. Conversations are written > into signed, tamper-evident records built on Holochain, encrypted with > a key only the user holds. Tagline: "No one in control but you." Key facts: - Free download, no account needed for local use: https://yourownai.net/download/ - Offline models run fully on the user's hardware (Vulkan/Metal, optional CUDA engine for NVIDIA) - Users author AI characters with personalities, memories, and knowledge; characters can be exported and imported as cryptographically signed packs - Projects: agentic coding in chat - the AI reads files, edits, and runs commands with per-action user permission, every step recorded - Every conversation is exportable, and exports can be signed so anyone can verify them at flowsta.com - Everything backs up to the user's own Flowsta Vault on their device - never to company servers - A local OpenAI-compatible endpoint (http://localhost:11435/v1) serves the user's AIs to external apps and agent frameworks ## Uses - [Talk with your documents, privately](https://yourownai.net/uses/private-documents/) - [Code in your own building](https://yourownai.net/uses/code-in-private/) - [Health stays home](https://yourownai.net/uses/health-stays-home/) - [Characters that are truly yours](https://yourownai.net/uses/your-characters/) - [Receipts for AI work](https://yourownai.net/uses/receipts-for-ai-work/) - [The engine under your other apps](https://yourownai.net/uses/engine-for-other-apps/) - [AI where the internet doesn't reach](https://yourownai.net/uses/works-offline/) - [Frontier power, only when it's worth it](https://yourownai.net/uses/frontier-when-worth-it/) ## Pages - [Features](https://yourownai.net/features/) - [Pricing](https://yourownai.net/pricing/) - the app is free; paid plans add online models with a monthly allowance - [Privacy](https://yourownai.net/privacy/) - the complete list of what ever leaves the device - [Support](https://yourownai.net/support/) ## Documentation - [Your Own AI Docs](https://docs.yourownai.net) - full documentation, including the local endpoint reference at https://docs.yourownai.net/external-apps/
