## Merlin AI

Merlin is built around a simple idea: instead of opening a separate chat tab for every task, you summon one assistant with a click while staying inside whatever you are reading or working on. The extension injects a sidebar on any web page, so it can read the article, the PDF, the YouTube transcript or the Gmail thread you currently have open and respond with that context already loaded. That makes summarization, rewriting, replying and research feel like part of the page rather than a separate tool.

Under the hood Merlin routes requests across a broad set of models — OpenAI's GPT family, Anthropic's Claude, Google's Gemini, DeepSeek, Mistral, Meta's Llama and others — so you can pick the model that suits a task without holding separate subscriptions for each. Beyond chat there is an image generator with multiple models and aspect ratios, a search mode that answers questions from live web results, document and video summarization, and a library of saved prompts. Newer additions like Projects (reusable knowledge bases) and Crafts (generated diagrams, mind maps and charts) push it toward light research and prototyping work.

Merlin is available as a Chrome extension, a web app, an iOS app and an Android app with synced history, custom prompts and custom bots across devices. The vendor highlights GDPR, ISO 27001 and SOC 2 alignment for data handling, and positions itself as accessible in 200+ countries where some other assistants are restricted. It is squarely a productivity assistant rather than a developer platform.

**Pricing & Plans:** Freemium. A free tier covers everyday use, and Merlin Pro is promoted at $2/month as a special offer, with the standard plan advertised around $19/month billed annually and described as replacing roughly $130/month of separate AI subscriptions. Paid tiers add higher limits, more capable models and advanced features.

- **Multi-model access in one place:** Switch between GPT, Claude, Gemini, DeepSeek, Mistral and Llama class models from a single interface instead of juggling separate subscriptions.
- **Universal page summarization:** Summarize articles, YouTube videos, PDFs and documents in place, then ask follow-up questions grounded in that content.
- **Writing and social drafts:** Draft and reply to emails in Gmail, compose posts and comments for X and LinkedIn, and repurpose web pages or videos into blogs and articles.
- **Image generation:** Generate images from prompts using more than 20 image models and multiple aspect ratios for web and social output.
- **Projects, Crafts and custom bots:** Build reusable knowledge bases, generate diagrams and charts from a prompt, and assemble custom chatbots from your own instructions and context.

**Strengths:** Replaces several separate AI subscriptions with one interface and one bill; Works inline on any page, so context is captured without copy-pasting; Covers a wide range of tasks: chat, summarization, writing, images, search and light research; Syncs across browser, web, iOS and Android with custom prompts and bots preserved

**Limitations:** The free tier is limited, and heavy use pushes you toward the paid plan; Covering so many features means individual tools may be less deep than dedicated apps; Requires trusting a third party with the pages and documents you send it, even with the stated compliance certifications

## Synopify

Synopify tackles a familiar problem: you land on a long page, a dense corporate site or an unfamiliar domain and you just want to know what it is about before investing time. The extension sits in your browser and, on demand, condenses all the content on the current page into a short, comprehensive overview. Instead of skimming headings and scrolling for minutes, you get the gist in a single view.\n\nWhat sets it apart from a plain summariser is the second half of its job. Synopify also tries to tell you who is behind the website. It uses the current tab's URL and title to extract insights about the page's content and to surface background information on the associated company, then presents a list of key facts alongside a condensed paragraph describing the page. That combination is useful for research, due diligence, sales prospecting and simply deciding whether a source is worth trusting.\n\nThe extension is distributed through the Chrome Web Store under the developer Synopify, based in Wellington, New Zealand. It is lightweight, installs as a normal Chrome add-on and runs in the browser where you are already reading. Its privacy disclosure notes that it handles personally identifiable information, authentication information, web history and website content, and that data is not sold to third parties.

**Pricing & Plans:** Free to install and use. There is no published paid tier; the extension is distributed through the Chrome Web Store at no cost.

- **One-click page summary:** Condenses all content on the current tab into a concise, comprehensive overview you can read in seconds.
- **Company background insights:** Uses the URL and page title to surface who the site belongs to, adding context beyond the article text.
- **Key information list:** Presents a structured list of key facts about the website next to the summary paragraph.
- **Skip manual scrolling:** Understand long articles, landing pages and corporate sites without reading through everything yourself.
- **Runs in Chrome:** A compact extension that works in the browser you are already using, with no separate app to open.

**Strengths:** Combines page summarisation with company background in one view; Removes the need to scroll through long pages to find the point; Free to install from the Chrome Web Store with no signup required; Works on the page you are already reading, so there is no context switching

**Limitations:** Quality depends on how clearly the target page is written and structured; Chrome-only, so it is not available for other browsers; Summaries of very short or media-heavy pages add little value
