Candid — AI video summaries with timestamps & chat for YouTube™

Candid — AI video summaries with timestamps & chat for YouTube™ Candid puts an AI summary beside the video you are watching: a short overview, then the key points grouped under headings, each with a timestamp that jumps the player to that moment. Google's Gemini watches the video itself, so it hears what is said and sees what is on screen: slides, charts, price cards, tables. It does not need the video to have captions. What you need • A free Gemini API key from Google AI Studio. The extension shows you where to get one and checks it the moment you paste it. • Google's free tier allows a limited number of requests a day. Google offers the Gemini API in many countries but not all, and requires its users to be 18 or older. What you get • The full transcript, searchable, with a note under each line of what was on screen as it was said. • Ask about the video, as in a chat. Answers come from what was already read, link the moments they came from, and say plainly when the video doesn't cover the question. A new look at the video happens only when you click, and its cost is shown first. • Short, Medium or Detailed summaries, or your own instructions. • Summaries in 12 languages: English, Español, Português, Français, Deutsch, Italiano, Polski, Русский, Türkçe, 日本語, 한국어 and 中文, or in the video's own language. • Translate the transcript on your device, with Chrome's built-in translator. • Summarize when you ask, or automatically for every video. • Optionally, write summaries with your own Cloudflare, Hugging Face or Anthropic key. Private by design • No account, no server, no analytics. Your keys and your saved summaries stay in your browser. • Video links and transcripts go only to the AI provider you use, directly and under your own key. Honest about what it read • A table in a summary says where its numbers came from, read on screen or said, and counts how many were really read off the screen. A claim that doesn't hold up is marked down. • The panel names the models that read the video and wrote the summary, and how long each took. • Before you start, it shows how long a summary should take, from measured runs, "give or take" a stated margin. Where nothing was measured, it shows no number at all. • A summary you come back to is shown as saved, with anything that has changed since, and is never passed off as new.
