Pricing
- Pricing model
- Freemium
Free tier plus paid plans metered by an internal credit and fair-use budget rather than a fixed request count. The vendor pricing page sits behind a Cloudflare challenge and could not be read; third-party guides quote about $19 a month for Pro, unconfirmed with the vendor.
Use tool ↗About Merlin AI
Merlin AI is a browser extension plus web app that opens an assistant over whatever page you are on, so you can summarise a YouTube video, draft a Gmail reply, translate a page or question a document without leaving the tab. A single subscription fans out across models from OpenAI, Anthropic, Google, Meta and others instead of paying each vendor separately. Chat history syncs to companion iOS and Android apps.

Pros & cons of Merlin AI
Buy it if you genuinely rotate between GPT, Claude and Gemini and resent paying three subscriptions — the aggregation is the whole value. If you live inside one model, its native app is faster, cheaper and gets features first.
Pros
- One subscription reaches a dozen-plus frontier and open models
- Extension surfaces the assistant directly on Gmail, YouTube, Google and LinkedIn
- Mobile apps sync history, so the browser session continues off desktop
- Real free tier for evaluating before paying
Cons
- 'Unlimited' paid plans are governed by an opaque fair-use credit budget users hit without warning
- Extension is desktop-Chromium only; mobile browsers get a reduced web app
- Feature parity with each underlying model's own app is never complete
- No developer API
Best for
- People who compare answers across frontier models before trusting one
- Heavy in-browser workflows: summarising videos, articles and inbox threads in place
- Users who want one bill instead of separate OpenAI, Anthropic and Google subscriptions
Not for
- Anyone who needs the newest model features on day one — aggregators lag native apps
- Developers wanting programmatic access; this is an end-user product, not an API
Watch out: The unlimited framing hides a usage ceiling — heavy users report throttling once monthly consumption crosses an undisclosed internal budget.
