Multi‑model AI, unlocked
Every model.
One key away.
GemGPT is the mobile app that puts every major AI model in your pocket. Connect your own OpenRouter or Gemini key for full control, or start instantly with the built‑in default — then search, compare, and switch between models as your needs change.
Free to install. You only pay your model provider for what you use.

How it works
Three steps from install to every model.
Add a key — or don't
Paste in your OpenRouter or Gemini API key. Your key, your billing, your usage stays between you and the provider — GemGPT never sees the bill.
Or just open the app
No key on hand? GemGPT comes with a default key built in, so you're chatting the moment you install it. Add your own later, whenever you want more control.
Search and switch models
Browse every model your key unlocks — from quick, lightweight assistants to frontier‑level reasoning — and switch models mid‑conversation.
Features
One app, every facet of AI.
Bring your own key
Connect an OpenRouter or Gemini API key directly in the app. Nothing routes through a server you didn't choose.
Default key included
Skip setup entirely. GemGPT ships with a working key so first‑time users can start chatting in seconds.
Full model catalog
Search the complete list of models available through your key — not just a curated handful.
Choose your power level
Pick light, fast models for quick answers, or step up to the most capable models for harder problems — you decide what you spend.
Switch without losing context
Move between models mid‑conversation while keeping the thread intact, so you can compare answers side by side.
Multiple keys, one app
Store more than one key and flip between providers depending on the task in front of you.
Model spectrum
From quick replies to frontier reasoning.
Every key unlocks a full range of models. Light models answer fast and cost less per use. Frontier models take more time and budget, but handle the hardest reasoning. GemGPT lists them side by side so you always know what you're choosing.
Pricing and availability depend on your provider and key.
