One Windows app that turns every API key you own into a private, super-chat.
Most AI tools make you buy their subscription. API.chat flips the script: bring the keys you already pay for (GPT-4, Claude, Gemini… even local models) and drive them all from one clean Windows app. No double-dipping. No browser tabs. No leaks.
| Problem we kill | How API.chat solves it |
|---|---|
| Juggling three web apps and two monthly plans | Single pane of glass. One shortcut opens every model. |
| Paying $40/mo just for "another chat box" | Pay-as-you-go. Use the same tokens you top up anyway. |
| "Where did that answer go?" | Local history. Every chat auto-saved to your PC, searchable offline. |
| Copy-pasting context each time | Reusable system prompts. One click to load your style, policy, or persona. |
| Privacy worries | Zero telemetry + open storage path. Verify it yourself. |
