Capture webpages and subtitles from YouTube or Bilibili, ask AI about the content, and sync linked Markdown notes with your local Obsidian vault.
I was drowning in an ocean of video — and couldn't find the single sip of water I needed.
As someone who struggles with mental stamina, I constantly found myself overwhelmed by the sheer flood of streaming video. A simple question — "How do I set up skills in Claude Code?" or "At what point in this calculus course does the professor cover the Mean Value Theorem?" — would force me to sit through 40-minute tutorials or rewatch entire lecture series from start to finish.
Podcasts were no different. To find the one moment where a creator shared their insight on a business model, I'd have to listen to the entire episode. Every time, the same exhausting pattern.
The root cause? Search results can never precisely match the question inside a video. Cultural barriers, commercial incentives, and algorithmic noise conspire to make searching within streaming media feel like finding a needle in the ocean. As the Chinese proverb goes — "Of three thousand streams, I only need one sip" — yet I was drowning before I could find it.
So I built Wisdio — a name born from Wise + Video. A browser extension that helps you understand webpages and YouTube or Bilibili videos, then keep the useful parts as reusable Markdown notes.
Wisdio connects web and video research to the Markdown knowledge base you already use.
Wisdio Companion is available in the Obsidian community plugin market. Connect Wisdio on desktop to keep linked notes as local Markdown files in your own vault.
Extract and search subtitles from YouTube and Bilibili. Use the transcript for AI questions, summaries, or timestamped notes without leaving the video.
A floating widget and bottom-sheet layout for supported Chromium-based mobile browsers, alongside the desktop Chrome side panel.
Real scenarios where Wisdio transforms your workflow
Watching a full-English YouTube lecture with no subtitles? Wisdio force-extracts the raw transcript, and AI helps you understand in real-time. Take notes in your language while the video plays — each note links back to the exact moment you wrote it.
Opened a 30,000-word industry report but don't have time to read it all? Capture the entire page as a "Context Pill" and ask AI: "What are the three core strategies mentioned?" Get the essence in seconds.
On the subway with just your phone? Wisdio's floating widget hovers quietly in the corner. Tap to open a full bottom sheet — read, highlight, ask AI, take notes — all optimized for one-thumb operation.
No subscriptions. No complicated setup. Just install and go.
Add Wisdio AI to Chrome from the Web Store. It takes 10 seconds.
Bring your own API key from DeepSeek, OpenRouter, or any compatible provider. You control the cost.
Open the side panel on a webpage, YouTube, or Bilibili, capture context, then chat with AI or save notes as Markdown.
Wisdio doesn't charge for AI usage — you use your own API key. We even show real-time token consumption and estimated cost in the panel, so you always know exactly what you're spending. No hidden fees, ever.
Export everything as clean Markdown files — compatible with Obsidian, Notion, Logseq, and any PKM tool
Export your entire knowledge base — timestamped video notes, AI chat summaries — as a clean .md bundle.
Pure Markdown output. Drag-and-drop into Obsidian, Notion, or Logseq. We're your knowledge outpost, not a data silo.
