A Claude Alternative With Every Model
10 Claude models, led by Claude Opus 5, plus the latest GPT and Gemini models and 390 models in total. Research with citations, smart routing and one fair price.
Why Look for a Claude Alternative?
Claude has earned its reputation for writing quality and careful reasoning. But Claude.ai keeps you inside one provider's ecosystem. When a task suits a different model, a fast one for iteration, a different flagship for a second opinion, you need another subscription and another tab.
A multi-model interface removes that friction without giving up Claude. You keep the models you like and gain the rest of the catalogue, one bill instead of several, and the freedom to test which model actually does your work best.
What JustSimpleChat Gives You
JustSimpleChat runs 10 Claude models through the Anthropic API, currently led by Claude Opus 5, Claude Sonnet 5, Claude Fable 5, alongside GPT-5.6 Luna, Gemini 3.5 Flash Lite and the rest of a catalogue of 390 models from 9 providers. The full list is on the models page, generated from the same registry the app runs on.
Auto Mode routes each prompt to a suitable model and you can override it at any time, switching mid-conversation with full context kept. Research mode adds multi-step web research with linked citations. Artifacts, file uploads and image generation are included on every plan.
If you have important conversations on Claude.ai, paste their public share links into the import tool and they become private chats in your account.
