AI for YouTubers: 8 prompts, and the AI uses YouTube makes you label

What can YouTubers use AI for without an AI label?

Cloning your own voice for voiceovers or dubs needs no AI label on YouTube. Its disclosure page lists that as a minor change. The script, the title, the thumbnail, the captions and the video ideas need none either, filed as "production assistance" or minor edits. We read that page and the monetization policies on 3 October 2026 and counted every AI example they give. Fourteen need no label. Eight need it. Five are named as unable to earn money at all.

The label tracks realism, not whether a model touched the file. YouTube requires it for content that "Makes a real person appear to say or do something they didn't do", alters footage of a real event or place, invents a realistic scene, or "Creates music that's the main focus of the video." The table maps the jobs a creator actually does to both pages, in YouTube's words.

Skipping the label on a realistic clip is the expensive mistake. YouTube can add the label itself when a file carries C2PA metadata or its systems detect AI. The page warns that creators who "consistently choose not to disclose" face removal of content or suspension from the YouTube Partner Program. You'll find the switch in YouTube Studio at upload, under Attributes, "AI use".

Does YouTube monetize AI content?

Yes, YouTube monetizes videos made with AI help. What it refuses is "inauthentic" content. That's the name it gave the old repetitious content policy on 15 July 2025, when it added that the rule covers videos that are "repetitive or mass-produced." The current wording names AI directly. YouTube won't monetize "AI-generated content made with generic or unoriginal templates giving the impression of mass production without adding the creator's original, authentic insights or perspective."

Two details in the policy text change how a creator should use AI. First, reviewers sample a channel, not every video. The list of what they look at includes "Video metadata (including titles, thumbnails, and descriptions)". So titles and thumbnails from one unedited prompt, repeated across a channel, are part of what a reviewer judges as template work. Second, a section titled "AI Personas Related to Sensitive Topics", bars any channel where an AI presenter "presents itself as a human expert" on health, legal issues, finances or politics. An avatar tool that reads your script as a synthetic doctor makes the whole channel ineligible, labeled or not.

The label itself costs nothing. YouTube's disclosure page says: "Disclosing AI content won't limit a video's audience or impact its eligibility to earn money." These rules move in the policy changelog. The most recent AI entry there, in August 2026, extended self-disclosure labels to Promote ad campaigns by 2 August 2026.

What is the best AI for YouTube scripts?

The best AI for a YouTube script is a flagship chat model (Claude Sonnet or GPT) fed your own past transcripts. Use Gemini when the source is someone else's public video, because the Gemini app reads a YouTube link. Gemini's Connected Apps help adds the condition: "To use public information from Google Flights, Google Hotels, Google Maps, and YouTube, Keep Activity must be on." Keep Activity also lets Google use those chats to improve its models. So research a competitor there, and draft your own unreleased script elsewhere.

Only you can test which model wins on prose for your channel. Paste the same outline into two models and keep the one whose draft you edit least. The table instead assigns each job by what the model or tool can do, with the hard limit to put in the prompt. Claude Sonnet, GPT and Gemini Flash all list context windows of 1,000,000 tokens in the model cost index (OpenRouter list prices of 20 August 2026). A full transcript fits in any of them. The YouTube prompts pack has 20 more, from the first 30 seconds to a sponsor read that fits the video.

Prompt 1, research a competing video (Gemini, public videos only): "Watch this video: [YouTube link]. List its hook in the first 30 seconds word for word, the promise it makes, each section with its timestamp, and the three questions viewers ask most in the top comments that the video does not answer. Do not summarize the opinions; I want the structure and the gaps."

Prompt 2, hook and outline: "I make [niche] videos for [audience]. Here are my notes for the next video: [notes]. Write five hooks of under 30 words, each opening on a different thing: a result, a mistake, a number, a question, a before and after. Then write an outline with a one-line promise and five sections, each with the single point it proves. Use only facts from my notes; mark anything you would need me to check with [CHECK]."

Prompt 3, the script in your voice: "Here are transcripts of two of my videos: [paste]. Write the script for the outline below in the same voice: my sentence length, my phrases, how I open sections, how I talk to the viewer. Target [N] words. Write it to be spoken: short sentences, no parentheses, no lists read aloud. Outline: [paste]." Get [N] from your own pace: divide the word count of a past transcript by its length in minutes, then multiply by the minutes you want. Keep the [CHECK] marks from prompt 2 and verify every one before recording. The model writes a figure as confidently when it invents one.

How do you write YouTube titles, descriptions and chapters with AI?

You write them from the finished transcript, with YouTube's own limits inside the prompt. Titles stop at 100 characters and descriptions at 5,000, per YouTube's video settings help. Chapters need a first timestamp of 00:00, at least three timestamps and at least 10 seconds each, per its chapters help.

Prompt 4, titles: "Here is the transcript of my video: [paste]. Write 20 titles under 100 characters, putting the topic words first. Use five angles, four titles each: result, mistake, number, question, comparison. Every title must be a promise the video keeps; flag any that overstates what the transcript shows. Show the character count after each." Pick three that differ in angle and load them into YouTube's Test & Compare. It runs up to 3 titles and thumbnails, finishes within two weeks and picks the winner by watch time, not clicks.

Prompt 5, the description: "From this transcript, write a YouTube description. The first two lines say what the viewer gets, in plain words, with the main search phrase [phrase] once. Then a 100-word summary, then the links section with these links: [links]. No hashtags in the first two lines, no claims the transcript does not make, under 1,500 characters." The 1,500 is a house choice to keep it readable. YouTube's cap is 5,000.

Prompt 6, chapters: "Here is my transcript with timestamps: [paste]. Write YouTube chapters: the first at 00:00, one each time the topic changes, no chapter shorter than 10 seconds, between 5 and 10 chapters in total, each title under 40 characters and written as what the viewer learns. Use only timestamps that appear in the transcript." The last sentence matters. A model that can't find a timestamp will invent a round one. YouTube also makes automatic chapters, and the box allowing them "will be checked for all new uploads" unless you untick it. Your own timestamps override them.

Prompt 7, Shorts from a long video: "From this transcript with timestamps, find the six moments that work alone as Shorts under 60 seconds: each must open on a complete thought and end on a payoff. For each give the start and end timestamp, the first line as spoken, and a title under 40 characters." YouTube counts uploads "up to three minutes in length that are square or taller" as Shorts, so a 60-second cut leaves room to trim. For the same video on other platforms, the social media prompts pack has 20 more, from first-line hooks to captions for each platform.

What is the best AI for YouTube thumbnails?

The best AI for a YouTube thumbnail is an image model that edits a real photo of you, such as Google's Nano Banana. Ask Studio, the assistant built into YouTube Studio, is the other pick: it "analyzes your video's transcript and themes to suggest thumbnails." Editing a frame from your own video keeps your face and setting real. YouTube's disclosure page counts a thumbnail as production assistance, so it needs no label.

YouTube's thumbnail help sets the spec, as of October 2026: 16:9, a recommended 3840 by 2160 pixels with a minimum width of 640, JPG or PNG, under 2 MB from a phone and 50 MB from a computer. Custom thumbnails need a verified account. Thumbnails with nudity, violence, hate speech or harmful content can earn a strike, and repeat offenses can remove custom thumbnail rights for 30 days.

Prompt 8, the thumbnail edit: attach a sharp frame of yourself from the video and send "Edit this photo into a 16:9 YouTube thumbnail. Keep my face exactly as it is. Place me on the right third, looking toward the left. Replace the background with [one object that shows the video's result] on a plain [colour] backdrop. Add the words [three to four words] in heavy white letters on the left half. Nothing else in the frame." Then attach your thumbnail beside two from the top videos for the same search and ask any chat model that reads images: "Shrink all three to phone size. Which is readable first, and what one change would make mine win?" Test the two best in Test & Compare. The best AI image generators compares the image models on text and faces.

Which paid AI tools are worth it for a YouTuber?

Start with the free AI already in YouTube Studio (Ask Studio thumbnails, Test & Compare, automatic chapters, automatic captions and dubbing into 20 languages from English). Then pay for one chat plan. Add a specialist only for a job the chat plan can't do. Prices below are in US dollars, read on 3 October 2026.

Avatar tools such as Synthesia and InVideo AI appear in most roundups for faceless channels. Under the AI personas rule above, an avatar presented as a human expert on health, law, money or politics can't earn. So check the topic before the tool.

Whizi puts GPT, Claude Sonnet, Gemini and 280+ other models on one login. Its Pro plan ($29.99 a month, $19.99 billed yearly) adds 100 image generations a month across Nano Banana, Flux and Whizi Image. A project per channel holds up to 32,000 characters of instructions and 10 pinned files of up to 10 MB, so your transcripts and style notes go into every script chat. Whizi has limits too. Starter at $15.99 has no image generation. And Whizi has no YouTube search data, no video editor and no voice cloning, so vidIQ, Descript and ElevenLabs still do jobs it can't.

What should a YouTuber never paste into an AI chat?

Never paste a sponsor contract under NDA, an unannounced brand deal, a viewer's email or address, your Google account or AdSense details, or footage of people who have not agreed to appear into a chat app that trains on your inputs. ChatGPT and Gemini do by default on personal plans. The Gemini app's YouTube link reading only works with Keep Activity on, and that's the setting that allows that use. Turning off AI training walks through each switch, and what never to paste into an AI chat has the general list.

Replace the sponsor's name and the fee with placeholders such as [BRAND] and [FEE] before asking for help with a sponsored segment, and swap them back in your own document. If a writer drafts scripts for you, the ownership and contract questions are the same ones AI for copywriters covers. For long written posts from a video, see writing blog posts with AI.
