ChippyAI
Chippy is a lightweight way to get ChatGPT-style help while browsing without leaving the page, and its bring-your-own-API-key model means there's no separate subscription to manage once you're past the daily free quota. The tradeoff is that it depends entirely on your own OpenAI key for any real usage, so the actual cost shifts to your OpenAI bill instead of a Chippy invoice.
Pros
- No account creation required to start using it
- Conversations and API keys stay local rather than on a remote server
- Covers summarizing, research, translation, and Q&A in one extension
Cons
- Free quota is only 20 GPT-3.5 queries a day
- Real ongoing use requires your own OpenAI API key and its associated cost
- Chromium-only, with no Firefox or Safari version
