YouTube Description & Timestamp Generator
Don't have a summary written yet? Type your video topic and generate one with AI — or paste a rough list of chapters in any order/format ("Intro - 0:00" or "0:00 Intro", one per line) and get back a clean, YouTube-ready description with properly formatted, clickable timestamps.
Add an outro (subscribe/social links) and we'll assemble the whole description for you, ready to copy and paste.

How it works
- 1New video, nothing written yet? Type your topic under "Generate summary from topic" and click Generate — it writes the opening for you.
- 2Already have chapters? Paste them, one per line, in either "0:00 Intro" or "Intro - 0:00" format.
- 3Add an outro/CTA block if you want one, then click Generate description and copy the result into YouTube Studio.
When to use this
- You just finished editing and have a rough, unordered list of chapter timestamps to clean up.
- You have nothing written at all and want an AI-drafted opening to build from.
- You want a consistent outro block (subscribe/social links) without retyping it every upload.
A worked example
Paste "Intro - 0:00", "The setup - 1:24", "What went wrong - 5:10", "Final results - 9:45" in any order, and the tool sorts them ascending, formats each as "0:00 Intro", "1:24 The setup" and so on, and assembles them under your summary — meeting YouTube's requirement of at least 3 timestamps starting at 0:00 for clickable chapters to appear.
Frequently asked questions
What makes YouTube turn timestamps into clickable chapters?+
Your description needs at least 3 timestamps, the first one must be 0:00, they must be in ascending order, and each chapter needs to be at least 10 seconds long. This tool formats them correctly, but you're responsible for the actual timing.
Can I use this for a video without chapters?+
Yes — just leave the chapters box empty and use it purely to format your summary and outro.
Why does the first sentence matter so much?+
Only about the first 125 characters of your description show before YouTube's "...more" cutoff — the AI-generated summary is written to work as a standalone hook within that limit, not just the start of a longer paragraph.
Does the format of my chapter list matter?+
No — paste them in whatever order and format you have, "Intro - 0:00" or "0:00 Intro", one per line. The tool normalizes them into the exact format YouTube requires for clickable chapters.
Can I edit the result before publishing?+
Yes — the output is a plain-text draft, not locked formatting. Edit freely before pasting it into YouTube Studio.
