MensorAI is an AI-powered research workspace designed for creators who work with video content, particularly on YouTube. It addresses the challenge of turning watched videos into usable material for scripts, essays, newsletters, or other creative outputs by providing structured tools for capturing, organizing, and reusing insights from video sources. The platform emphasizes privacy, with each user's workspace set to private by default unless content is explicitly published.
The core workflow involves capturing a video source—either by pasting a video link or using the MensorAI browser extension while watching YouTube. Once a video is added, the platform generates a Source Card that includes the video transcript, metadata, notes, timestamps, and extracted ideas. Users can pull out quotes, claims, and angles directly from the video, preserving the context and moment of origin. Features like Quote Clips allow saving specific lines with their exact timestamps, while Angle Cards help transform sources into actionable hooks, framings, or questions. Draft Packs bundle together hooks, claims, quotes, examples, and outlines to facilitate the transition from research to content creation.
MensorAI also integrates AI features such as Source Chat, which enables users to ask questions about their saved research and connect different sources to inform their next project. The workspace supports structured notes, tracking of follow-ups and angles, organization with tags, and workspace analytics. Users can publish public breakdowns if they choose, and the platform offers knowledge graph syncing and Socratic prompts in higher-tier plans. All sources, notes, and quotes remain accessible even if a subscription is canceled, though AI features become unavailable.
Delivery is primarily through a browser extension that overlays a sidebar on YouTube, allowing users to capture and annotate material without leaving the video. The service is currently focused on YouTube but indicates plans to expand to other media formats. Pricing is subscription-based, with Starter, Plus, and Pro tiers, all offering a 7-day free trial with full Pro access and varying limits on features such as Draft Packs, AI Source Chat, and AI requests per day.
MensorAI sits in PulseGate's Education & learning category. It helps users efficiently learn from YouTube videos by enabling AI-powered note-taking, search, and Q&A across their video library. It is built as a consumer product for students. A free plan is available; paid tiers begin at $8. It runs on the web and embeddable surfaces.
