YourChatGPTandGemini,nowanAPI.
Use the AI subscription you already pay for in your code.
No new keys. No new bills. No vendor to onboard.
The AI you already use,
in the shape of an API.
We don't think you should pay for AI twice. So we built the wire that connects what you already have to the code you're already writing.
Built for every workflow. Polished desktop app.
Use the AI you already pay for.
Connect ChatGPT Plus or Gemini Advanced via your browser session. No new API keys, no separate billing.
Test inside the app.
Switch between local and public endpoints, pick any model, and verify the full pipeline before writing a single line of code.
Localhost to the internet, in one click.
Toggle the switch. You'll have a stable public HTTPS URL pointing back to the AI on your machine — same address every session.
Drop it in your project.
Generate a self-contained Gemini server with your tokens baked in. Four files. One command. Runs anywhere Python runs.
Temporary chat by default.
Every request uses Gemini's temporary mode out of the box — nothing saved to your history unless you turn it on.
Drop in any client.
Works with the OpenAI SDK, LangChain, LlamaIndex, and anything that speaks chat-completions. Change one URL, nothing else.
Three lines of code. Any model.
Same endpoint, same JSON shape, every model. Change the model name to switch providers — Spike routes automatically.
