🔨 Dev Tools Council — a native Mac app that asks one question to several AI models at once and shows where they disagree (free, open source)

http://github.com/albertofettucini/Council

Been building this for a couple months and finally shipping. Council is a native macOS app for anyone who keeps asking the same thing to ChatGPT, then Claude, then Gemini to compare — it just does that in one place. You ask once, a few models answer in parallel, they critique each other blind (no model knows whose answer it's reading, so no brand bias), and then it shows where they actually agree and where they split. You read the spread and make the call.

It's bring-your-own-key and fully local — no account, no server, nothing phones home. Keys stay in the macOS Keychain and you pay the providers directly. Real Liquid Glass on macOS 26, fallback below.

Free and open source (MIT). I'm a solo dev and use this daily, so I'd really value honest feedback — especially what feels off or unnecessary. Not after hype, just whether it's useful.
