TypingMind

TypingMind is a front end that lets you chat with OpenAI, Anthropic, Google and other models using your own API keys. It adds features the default apps lack, such as folders, prompt libraries, plugins and team sharing.

Because you pay the provider per token, heavy users can spend less than flat subscriptions. A one-time license is available, and a white-label version exists for agencies.

Good for people who want power-user features without self-hosting.
