Merlin

Merlin removes the friction of jumping between AI tools by putting ChatGPT, Gemini, and other models into a single Chrome extension that works on any website. No registration wall, no ads, and the free tier is usable from day one, though daily limits kick in. You can write, code, research, or generate images without leaving the page you're on. The catch is that it's browser-only: if your workflow lives in desktop apps or the terminal, this won't help. It's for students writing essays across multiple tabs, developers debugging snippets while reading documentation, or content creators who spend their day in the browser and want AI assistance without context-switching. If you need AI outside web-based work, look elsewhere.
