## Full description

Claude answers independently, then a comparison step lists where the two responses match, where they diverge, and which points to verify yourself, instead of blending them into one reply. On iPhone it runs through Apple Shortcuts using your own ChatGPT and Claude accounts, with no API keys or server. The Android version uses free Kimi K3 and Gemini Flash keys, and the code is open source on GitHub.
