Toolglade’s take

Merlin is a capable multi-model assistant that leans harder than most sidebars into research with live citations, knowledge-base Projects, and diagram generation. That extra tooling is a real differentiator, and the two-seat Teams minimum helps tiny groups. The catch is the usual one for this category: plans are credit-gated, and premium-model heavy use can push you up the ladder. Merlin is operated by Foyer Tech in Delaware, and there is no publicly disclosed institutional funding, so evaluate it on product merit rather than backing.

About Merlin AI

Merlin AI is a freemium Chrome extension and web app that unifies many leading models under one subscription. It offers one-click answers, summarization, content repurposing, and real-time research with live web citations, plus knowledge-base Projects, diagram generation, and code snippet tooling. Built by Foyer Tech, it targets individuals and small teams who want broad model access affordably, with a Teams plan starting at a two-seat minimum.

Merlin AI (getmerlin.in) is an AI assistant delivered as a Chrome extension and companion web app, built by Foyer Tech. It bundles multiple frontier models, including options built on GPT, Claude, Gemini, DeepSeek, and Llama, so you can get one-click answers, summarize content, repurpose text, and run real-time research that cites live web sources. Beyond basic chat, Merlin adds Projects for custom knowledge bases, Crafts for diagram generation, and tooling for code snippets. Merlin targets individuals and small teams who want a single, affordable subscription spanning many models rather than paying for each provider separately. It is available on desktop through the extension and works, with reduced functionality, in mobile browsers. The Teams plan lowered its seat minimum to two, making it easier for very small groups to standardize on one assistant. In the AI-sidebar market Merlin sits alongside Monica, Sider, and MaxAI. Its distinguishing points are the research-with-citations focus, knowledge-base Projects, and diagram generation. As with peers, value depends on how the model credits and plan limits map to your usage, and heavy users of premium models should confirm caps before committing.

TL;DR

Merlin AI is a freemium Chrome extension and web app that bundles many leading models under one subscription. It stands out for research with live citations, knowledge-base Projects, and diagram generation, alongside standard summarization and writing. Pro is reported around $19 per month and Teams around $15 per seat with a two-seat minimum. It is built by Foyer Tech with no publicly disclosed institutional funding.
