Show HN: Teletyped – Free interface for multiple AI models (chat.teletyped.com)

We built a clean UI for ChatGPT and Claude that's now completely free. Just plug in your API keys and get:

- Switch models mid-chat

- Edit AI responses

- Saved & temporary chats

- Adjustable temperature

- Multiple themes

No subscriptions. We made this because we were tired of switching between different AI interfaces. Would love your feedback!
