I will develop custom desktop application using rust, tauri , react

I can build the application for Windows (.exe/.msi), macOS (.dmg), and Linux (.deb). Please note that for macOS builds, specific Apple Developer certification is required if you intend to distribute it publicly on the App Store.

If you choose to use cloud providers like OpenAI or Anthropic, you will need your own API key, and you are responsible for those usage costs. However, I can also implement "Local LLMs" (using Ollama) which run entirely offline for free on your machine.

Rust and Tauri create applications that are significantly smaller (often under 10MB) and use roughly 50% less RAM than Electron apps. This ensures your application feels instant and does not slow down the user's computer.

Local RAG (Retrieval-Augmented Generation) allows the AI to "read" your PDF or text documents to answer questions. Because I implement this locally using Rust, your documents are processed entirely on your device and are never sent to a cloud server, ensuring 100% privacy.

Yes. You receive the full source code for both the Frontend (React) and Backend (Rust), giving you complete ownership and the ability to modify the project in the future.

I provide a specific period of bug support after delivery. For new features or major updates later on, we can open a new order or discuss a maintenance retainer.

Generally, no. Desktop applications run on the user's machine. However, if your app requires a centralized database (like user login syncing across devices), we will need to discuss setting up a cloud backend (e.g., Supabase or Firebase).
