A YouTube description does more work than most creators realize
Most viewers never read a YouTube description in full — but YouTube's search and recommendation system reads every word of it, and the first two lines show up before the "Show more" fold on both desktop and mobile, whether a viewer clicks to expand it or not. A blank or one-line description wastes both: less for YouTube's algorithm to match your video against real searches, and a missed chance to earn the click from that first visible line. This free tool writes all three pieces that actually matter — the hook, the full body, and a hashtag block — from a short summary of your video.
Chapters, with placeholder timestamps you fill in
List your video's segments — Intro, then whatever comes next, one per line — and this tool auto-numbers them into a chapters block with placeholder timestamps spaced a minute apart. No AI can know your video's real cut points before you've finished editing it, so these timestamps are deliberately a starting scaffold, not a guess dressed up as fact: once your final edit is locked, replace each placeholder with the real time that segment begins. YouTube requires the first chapter to start at exactly 0:00 and at least 3 chapters (each at least 10 seconds apart) before it will display a chapter bar under your video at all.
Add your website, WhatsApp, and social links (one per line) and they're spliced into the description exactly as you typed them — never rewritten or guessed by the AI, since a wrong link is worse than no link at all.
Where the hashtags actually show up
YouTube displays the first 3 hashtags from your description above your video's title, both in search results and on the watch page — this tool generates 6, so you have a couple of alternates if the first 3 feel off for a particular upload. Keep them relevant to the actual video content; YouTube can penalize videos whose hashtags mismatch what the video is actually about.
Once your description is ready, point viewers somewhere concrete — link your free BizGo business page in the "Links" section above so anyone who finishes watching can see your services and contact details in one click. See the box above to get started.
