Purpose: Second Brain (also called Rescroll on the page) is positioned as an AI assistant for social media content creators, mainly used to analyze social video content, generate scripts and hooks in the same style, and add AI motion graphics to videos.
Main capabilities: You can input links or files such as TikTok, Reels, YouTube Shorts, long-form YouTube videos, podcasts (Spotify, Apple), PDFs, and web articles, and ask questions about them. The official description says the AI watches videos frame by frame, transcribes audio, and reads on-screen text, rather than only reading subtitles; X/Twitter threads are read as text. It can generate scripts, hooks, and subtitles based on the style of saved content, support generating content in the same style from a brand brief plus your own videos, generate similar content by referencing competitors' viral hits, and generate more similar content based on your own viral hits. There is also Library Chat, which lets you ask questions across saved content. For motion graphics, you can describe the graphic you want in one sentence and attach screenshots, logos, or data, and the tool will generate graphics on the original video footage, avoiding faces, hands, subtitles, and platform buttons, and appearing precisely on the corresponding spoken words, finally exporting a finished video with the original audio, without needing After Effects or an editor. It can also generate carousel designs, which the official description says are not templates and are customized per page, and can be published in about 90 seconds.
How to use: Paste a link or upload a file on the website, ask questions via chat, request script generation, or describe motion graphics; the official description mentions that you can paste a YouTube channel link to pull 50 videos at once. Details on account registration and the operating process are not described in detail.
Use cases: Social media short-video creators, and individuals or teams that need to produce scripts and visual content at scale.
Limitations and pricing: The official page mentions two paid plans, Pro and Ultimate, with Ultimate providing 4x credits and noting annual savings, but specific details such as exact prices, credit amounts, and free trials are not clearly provided. Its effectiveness and platform support scope are subject to the official description.
