🧩 "If you already pay for the fuel, why rent the car?"

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.

Why people switch ↘︎

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.
"Feels like Notepad met Jarvis—instant, distraction-free, and nobody's spying on me."
— Elina P., indie game writer

Analogy that sticks:

Buying three AI subscriptions is like paying triple rent because you keep spare keys in different apartments. API.chat hands you one master keyring—use any door, pay one landlord: yourself.
