Prompt
Act as a YouTube SEO editor who writes descriptions and chapters only from a pasted transcript and the metadata in Inputs. You never invent view counts, subscriber numbers, upload dates, links, or performance claims that are not in Inputs. You work only from Inputs. Do not invent stats, citations, quotes, URLs, names, IDs, or records that are not in Inputs. Inputs: - Video transcript with the timestamps you already have: [Transcript] - Working title and target keyword: [Title] - Links or CTAs you actually want used, or NONE: [Links] - Audience and skill level: [Audience] - Language: [Lang] - Output format: [Format] Generate: 1. Metadata ledger: quoted timestamps, title, keyword, links, audience. Forbidden: invented upload dates, invented view counts, invented subscriber numbers. 2. Description: the first 150 characters contain the target keyword and the video's actual promise from the transcript. Two or three short paragraphs after that, facts only from the transcript. 3. Chapters: one line per chapter using only timestamps present in Transcript, in HH:MM:SS order, each caption describing what is said or shown per the transcript. If a viewer-relevant section has no timestamp, write NOT IN TRANSCRIPT. 4. Tags: 10-15 tags built from transcript words and the target keyword. No unrelated trending tags. 5. Do-not-say pass: list the claims you refused (subscriber counts, superlatives the transcript does not support, guaranteed results). 6. CTA: paste from Links only; if Links is NONE, write one soft subscribe line and mark external CTA NOT IN INPUTS. 7. Timestamp gaps: sections viewers will search for that have no timestamp yet - name them. 8. Format as Format. Constraints: - Chapters never contain a timestamp that is not in Transcript. - No invented statistics and no clickbait the transcript cannot back. - Mark NOT IN TRANSCRIPT wherever Inputs are silent. End with a gaps list of five bullets the user still owes you.
Instructions
Paste the transcript with its timestamps, your working title, and target keyword. Replace every [bracket] with your details before running. Works on ChatGPT, Claude, and Gemini.

Example Input
Transcript (timestamps as exported from the editor): 00:00 Intro - what we are building: a floating garage shelf 00:38 Tools list: circular saw, drill, 4mm bit, stud finder 02:10 Cutting the 18mm plywood to 1200 x 400 04:05 Finding studs and marking the wall ledger 06:22 Installing the ledger with 70mm screws into studs 09:40 Adding brackets and the front rail 12:15 Loading test with 60kg of paint tins 13:50 Mistakes to avoid: skipping the stud finder Title: Floating Garage Shelving Build (18mm Plywood) Keyword: garage shelving build Links: NONE Audience: first-time DIYers with a small garage Lang: English Format: ledger + description + chapters + tags + refused + CTA + gaps
Example Output
1. Metadata ledger. Quoted timestamps: 00:00, 00:38, 02:10, 04:05, 06:22, 09:40, 12:15, 13:50. Title: Floating Garage Shelving Build (18mm Plywood). Keyword: garage shelving build. Links: NONE. Audience: first-time DIYers with a small garage. Forbidden: invented upload dates, invented view counts, invented subscriber numbers. 2. Description. Garage shelving build walkthrough: a floating shelf from 18mm plywood that held 60kg of paint tins in our loading test, built with a circular saw and a stud finder. We cut two boards to 1200 x 400, hang a wall ledger into studs with 70mm screws, add brackets and a front rail, then load it up. The video closes with the one mistake people keep making: skipping the stud finder. Full tool list at 00:38. 3. Chapters. 00:00 Intro - what we are building: a floating garage shelf 00:38 Tools list: circular saw, drill, 4mm bit, stud finder 02:10 Cutting the 18mm plywood to 1200 x 400 04:05 Finding studs and marking the wall ledger 06:22 Installing the ledger with 70mm screws into studs 09:40 Adding brackets and the front rail 12:15 Loading test with 60kg of paint tins 13:50 Mistakes to avoid: skipping the stud finder Anything after 13:50 - NOT IN TRANSCRIPT (no further timestamps exported). 4. Tags. garage shelving build, floating garage shelf, 18mm plywood shelf, garage storage diy, wall ledger shelf, stud finder shelf, plywood shelving, garage shelf brackets, loading test, small garage storage, diy shelving tutorial 5. Do-not-say pass. Refused: subscriber count (not in Inputs), "strongest garage shelf on YouTube" (superlative not in transcript), "holds any weight" (the test was 60kg, not any weight), guaranteed stud spacing on every wall. 6. CTA. Links: NONE. Soft line: "If this garage shelving build helped, subscribe for the next shop project." External CTA NOT IN INPUTS. 7. Timestamp gaps. - Safety gear (goggles, ear protection) - viewers search for it, no timestamp. - Screw pattern spacing on the front rail - shown but not timestamped. - Wood finish or paint step - not in the transcript at all, so no chapter possible. Gaps the user still owes you: end-screen timestamps, affiliate or plan links if any, upload date, series name, whether an end card exists.
