What it does ChatALL is an Electron desktop app that acts as a unified client for roughly 30 AI bots—ChatGPT, Claude, Gemini, Bing Copilot, Llama, Perplexity, and a long tail of Chinese and open-source models. You type once, it broadcasts the prompt in parallel, and streams back responses side-by-side. Local chat history, dark mode, and multi-column layouts are included.

The interesting bit The project is refreshingly honest about its own fragility: it warns that web-scraped bots “rely on reverse engineering and are difficult to maintain, often breaking unexpectedly.” That transparency is rarer than you’d think. It also admits in the credits that “GPT-4 contributed much of the code”—a nice meta-touch for a tool built to compare LLMs.

Key highlights

• Supports both web-login and API access where available; API bots are flagged as more reliable.
• Quick-prompt mode lets you fire off follow-ups without waiting for the previous round to finish.
• Local-only storage for history, settings, and logins; anonymous telemetry strips actual prompt/response content.
• Cross-platform: Windows (.exe), macOS (.dmg / Homebrew cask), Linux (.deb, .AppImage, AUR).
• Built with Vue 3 and Vuetify 3; contributor guide exists for adding new bots.

Caveats

• You bring your own accounts and API keys; ChatALL is a client, not a proxy or credential provider.
• Web-connected bots break when providers change their UI, which is often.
• Resetting the app requires manually deleting filesystem directories—no in-app “clear data” button.

Verdict Worth a look if you benchmark models, debug prompts across backends, or just want to stop opening seventeen browser tabs. Skip it if you only use one API and don’t care about side-by-side comparison.
