AI Analysis

●●SolidCozySolve My Problem

Always-on-top floating window beats app-switching when you're deep in code.

Strengths
  • •Tauri v2 + Rust backend means genuinely low RAM usage compared to Electron alternatives.
  • •OS keyring integration stores API keys securely instead of plain text config files.
  • •Local SQLite persistence keeps chat history on-device with no cloud dependency.
Weaknesses
  • •Multi-provider support is just Vercel AI SDK wrapping existing APIs, no novel architecture.
  • •Always-on-top feature exists in Raycast, Cursor, and several other dev tools already.

Post Description

Built an desktop AI companion that always pinned at top.

Some of the features:

- Lightweight: Built on Tauri v2 + React + Rust for low RAM usage.

- Always-on-Top Floating Mode: Pinned window stays on top so you can code and query AI side-by-side (no more app-switching!).

- Secure Keyring Storage: API keys are saved directly in your OS secure Keychain/Keyring

- Local SQLite Database: All chat history and threads are saved locally on your device.

- Multi Provider Support: Connect to Gemini, OpenAI, Anthropic, Groq, local Ollama, or custom endpoints.

It is Open-source and free to download. Availabe for Windows, Mac and Linux.
