TL;DR

A professional chat interface that lets you plug in your own API keys so you can stop paying for multiple $20-a-month subscriptions.

Who is this actually for?

Power users and developers who need to switch between GPT-4, Claude, and Gemini in a single tab without the subscription bloat.

The Good

• You only pay for the tokens you use, which is usually way cheaper than a flat monthly fee for casual use.
• The UI is actually functional, with folders, search, and prompt libraries that put the default big-tech interfaces to shame.

The Catch (Potential Downsides)

Managing your own API keys and billing across three different providers is a friction point for anyone who just wants things to work. If you are a heavy user, your API bill might actually end up higher than a standard subscription.
