Hedian: AI Video Explainer

Hedian is an AI video explainer for the videos you scroll past. You see a short video about something you want to understand. A money clip says inflation is eating your savings but never says why. A fitness clip tells you to use progressive overload and never says what that means. A cooking clip is in a language you do not speak. The speaker moves fast, skips the basics, and within a minute the video is gone and you are left with half an idea. Share the video to Hedian straight from your feed. About a minute later Hedian hands you AI notes on what the video actually said, in your language and at the level you choose. Every term it left hanging is defined underneath. Whatever is still unclear, you ask right there. Think of it as an AI tutor and AI note taker for videos, built for the ones you would otherwise forget. MORE THAN A VIDEO SUMMARIZER A video summarizer tells you a video was about compound interest. Hedian tells you how compound interest works, with the jargon unpacked. It reads the transcript, the text on screen and the frames themselves, then writes the version you needed the first time. It is video to text you can actually study: not a word-for-word transcription and not a bare summary. HOW IT WORKS 1. Share a video. Straight from the share sheet of Instagram, TikTok or YouTube, or paste the link from your clipboard. 2. Wait about a minute. Leave the app if you like. The work continues and the document is waiting when you come back. 3. Read, then ask. Ask AI anything about the video. Your question and its answer become part of your notes instead of a chat you will never find again. WHAT YOU GET - An explanation written at your level, in your language - A glossary of every term the video assumed you knew - The key points, laid out: the TL;DR without losing the why - Claims worth checking, flagged with the reason - Study notes you can sort into folders, search, and export on paid plans - A question box that never closes, so you can ask questions as you go A STUDY HELPER FOR WHAT YOU PICK UP ONLINE Learning from short videos is easy to start and hard to keep. Hedian turns each one into study notes with the terms explained and your own questions attached, so you can review it later instead of rewatching. Useful for software, finance, science, cooking, fitness and anything else people explain fast. TRANSLATE VIDEOS INTO YOUR LANGUAGE The video can be in any language. Hedian explains it in the one you pick, from eighteen languages, so you get the meaning in your own words rather than subtitles. The level adjusts per topic: advanced for a subject you know well, beginner for one you are new to. SAVE VIDEOS, SKIP THE WATCH LATER PILE Share a video here instead of adding it to a watch later pile you will never open. Saved videos become documents you actually return to. Folders you make yourself, search that works by meaning rather than exact wording, and a record of what you have understood. No thumbnails, no recommendations, nobody else's saves. WHAT HEDIAN IS NOT Hedian is not a social network. There is no feed and no discovery surface. It re-hosts nothing: no video is stored on your phone or served by us. There are no ads. What you save, what you search and what you ask are never shared with anyone else. We only count which screens you open and how many questions you ask, so we can improve Hedian; you can turn that off in Settings. PLANS Hedian is free to try. Paid plans raise how much you can analyse and ask each month, and unlock export. Subscriptions renew automatically and can be cancelled any time in Google Play. PRIVACY Your questions belong to you alone. They never enter anything shared with other users, and that separation is enforced by the database itself rather than by app code.
