Besides the big ones:
- Octal - App for Hacker News
- Poe - Quora’s implementation of ChatGPT
- Artifact - News app that lets you mark headlines as clickbait and then uses AI to rewrite them with helpful info
- LunaSea - Interface for my home instances of Sonarr and Radars
- Strong - Weightlifting app
- Diarium - Low-cost and straightforward journal app
Poe has options for their own AI (Sage), as well as OpenAI’s ChatGPT and Anthropic’s Claude. If you use the premium versions of either of those (GPT4 and Claude+), you have to pay.
