Monica
Monica is a browser-first AI assistant that puts chat, search, writing, translation, image generation, and PDF tools in one sidebar across Chrome, Edge, Windows, Mac, iOS, and Android. Hit Cmd+M or Ctrl+M on any page to open chat, summarize a selection, rewrite text, or run one of 80+ copy templates without switching tabs.
Standalone chat apps lock you into one model and one window. Monica routes tasks to GPT-5.5, Claude 4.6 Sonnet, Gemini 3.1 Pro, Sora 2, and dozens of other models from the same interface, then layers browser-specific workflows like Gmail reply drafts, YouTube timestamp summaries, and Google search answer panels. That combination targets people who need AI inside their existing sites, not a separate app to paste links into.
Students, developers, marketers, and customer support teams use Monica for research summaries, ChatPDF document Q&A, code help via Monica Code for VS Code, and batch content drafting. The free tier has daily limits; paid plans unlock Advanced Credits for premium models and agents like Deep Research and Browser Operator.
