Briefy
Briefy is an AI knowledge assistant that summarizes webpages, YouTube videos, PDFs, documents, and other long-form content into structured, easy-to-review formats while organizing saved summaries in a searchable knowledge base.
Briefy is an AI-powered summarization and knowledge-management platform designed for students, researchers, professionals, and anyone who regularly consumes large amounts of online information. Instead of reading lengthy articles, watching entire videos, or manually reviewing documents, users can give Briefy the content and receive a concise, structured summary that highlights the most important information.
The platform supports several types of content, including webpages, YouTube videos, text, and document files such as PDFs. Briefy can represent summaries in different formats rather than limiting users to a traditional block of text. Available views include Overview, Mindmap, Table, and Timeline, allowing users to choose a structure that better matches the type of information they are reviewing.
Briefy also provides interactive AI capabilities. Users can ask questions about the content they are viewing, request additional information from a summary, and refer back to the original source when they need additional context. Multilingual summaries and customizable output languages make the platform useful for users working with information across different languages. Premium capabilities also include multi-modal summarization and support for very long text—up to 2 million words according to Briefy's current plan comparison.
A major part of Briefy is its built-in Knowledge Base. Instead of treating summaries as temporary outputs, users can save them as "Briefs" and build a personal information repository. Saved Briefs can be reviewed, searched, shared, and queried through AI, effectively turning Briefy into a lightweight second-brain system for research and knowledge retention. Universal Search allows users to find information across previously saved material. Briefy is also accessible through browser extensions. It provides a Chrome extension for desktop users and a Safari extension for iOS, iPadOS, and macOS, enabling users to summarize content while browsing instead of repeatedly copying material into another application. Its summarization features can automatically become available on supported webpages and YouTube content after installation.
Briefy follows a freemium model. The Free plan currently provides 30 credits per month, while Premium and Ultra increase monthly allowances to 700 and 1,500 credits, respectively, while unlocking features such as PDF summarization, longer-text processing, Knowledge Base storage, source referencing, inline translation, and advanced summary views. Overall, Briefy combines AI summarization with knowledge management, making it especially useful for turning information overload into an organized and searchable personal knowledge library.
