What it is
Merlin is an AI assistant delivered as a Chrome extension, web application and native mobile apps that provides contextual AI responses from within web pages and supported sites. It aggregates access to multiple large language and multimodal models and offers realtime web search and reasoning alongside model inference. The product is presented as a tool for extracting summaries, generating and repurposing content from websites and videos, producing images, and assisting with code snippets and data queries. Merlin supports uploads of documents (PDF, PPT), video summarization and multilingual translation, and exposes features for creating reusable knowledge stores and custom chatbots. The service is available across platforms with synced history and preserved custom prompts and bots.
Key features
Merlin includes a one-click in-page chat interface that pulls context from the current website and provides summaries, search results and content generation without switching tabs. Projects allow users to build persistent knowledge bases from uploaded guides or documents for repeated, contextual querying. Crafts generates diagrams, infographics and interactive charts from prompts and can output web code snippets (including React and Shadcn-based components) that are editable. The product supports many AI models (examples listed include OpenAI, Claude, Gemini, Mistral, Llama and others), offers image generation across multiple models and aspect ratios, and provides tools for video transcription and summarization. Additional features include a prompt library, custom bot creation by combining instructions and context, CSV/XLS upload for data insights, and integrations on Gmail, LinkedIn, X and Google Sheets. Security certifications and compliance references are noted for data protection.
Use cases
The site describes use by students for summarizing lectures, creating study aids and building homework-help course bots; by marketers and creators for repurposing web content, generating brand-voice copy and producing social posts and images; and by entrepreneurs for idea brainstorming and visual planning using diagrams and mind maps. Developers are shown using Projects to incorporate codebase documentation, Crafts for prototyping and Merlin for contextual debugging and boilerplate generation. Consultants, product managers and analysts are identified as using live search and Projects to organise research, visualise findings with multiple diagram types and generate timely reports, and to query spreadsheets or databases for rapid insights.
