Merlin

Merlin is a versatile AI browser extension that brings the power of multiple large language models"including GPT-4, Claude, and Gemini"directly into your browser workflow. It excels at summarizing web pages, drafting emails, generating content, and answering questions without requiring you to switch tabs. The freemium model lets users test core features before committing, though the free tier's daily query limits can feel restrictive for power users. Paid plans starting at $14/month unlock higher usage caps and access to premium models, which is competitively priced against similar tools like Monica or Sider. The interface is clean and the contextual pop-up integration feels natural across Gmail, Google Docs, and general browsing. One limitation is that response quality can vary depending on which underlying model you select, and occasional latency spikes occur during peak usage. The multi-model approach is a genuine differentiator, giving users flexibility that single-model extensions can't match. Overall, Merlin is a strong choice for anyone looking to embed AI assistance seamlessly into their daily browsing routine.
