What is Merlin?
Merlin is an AI assistant that lives in your browser (press Ctrl or ⌘ + M on any page) and also runs as a web app and mobile apps. You can access a range of third-party models from OpenAI, Anthropic, Google, DeepSeek, Mistral, Meta and xAI, plus image models, from one interface.
Its strength is context: Merlin can summarise the page you are reading, a long YouTube video or a PDF, answer with web search, and draft emails or social posts where you are typing. That makes it a productivity layer rather than a specialist SEO tool.
Key features of Merlin
Multiple AI models in one place
Compare outputs from the models available in your account. Model availability and usage limits can change, so check the current options in Merlin.
Page, PDF and YouTube summaries
One click summarises the current page or video into key points, which speeds up competitor research and reading industry reports.
Writing where you work
Draft replies in Gmail, posts on LinkedIn or comments directly on the page through the extension.
Custom prompts and chatbots
Save reusable prompts, such as a brand-voice rewrite or a meta description generator, so a whole team writes consistently.
How IPSense and our clients use Merlin
Merlin is the research layer behind our client workshops and GEO audits. Because it puts several AI models in one place, our team can check in minutes how each model answers the questions a client's buyers ask.
- Summarise the top 10 competitor pages for a target query.
- Ask the same buyer question to several models and note differences in recommended brands.
- Turn findings into a short brief for the content team.

- You need SEO scoring or AI visibility tracking
- You only use one model and already pay for it
Why it is in the IPSense toolkit

Merlin: frequently asked questions
What is Merlin AI used for?
Merlin helps with browser-based research, summaries and writing tasks. You can use it to organise information from source material and prepare drafts for review.
Can Merlin help summarise web pages, PDFs and videos?
Merlin includes tools for summarising web pages, PDFs and YouTube content. The result depends on the material it can access, so check important points against the original source.
How can Merlin help with everyday business writing?
It can help prepare email drafts, rewrite text and organise ideas for content. Provide your audience, purpose and business details, then edit the output to match your voice.
Do AI summaries need human review?
Yes. Summaries can omit context or misread details. Check names, figures and conclusions against the source before using them in business content.
Is Merlin a replacement for an SEO strategy?
No. Research and drafting assistance are only part of the work. Your website still needs useful content, clear structure and performance review against business goals.
