Merlin AI

Browser AI sidebar with access to 20+ models

WritingFreemiumLLM-drafted

Part of this entry was LLM-drafted and is being polished.

Merlin is a Monica-style browser-sidebar AI extension — chat with 20+ models on any page, summarize / translate / write inline. Comparable feature set to Monica with slightly different pricing structure.

Editor's verdict

Direct Monica competitor. Quality is similar; pick whichever ranks higher in your Chrome store reviews and matches your usage. Both products serve the same 'one AI sidebar to rule them all' niche; if Monica's pricing fits better, go Monica.
