TL;DR
The subscribe decision happens on your channel page, not your latest video. Feed an AI assistant your niche, audience, and real posting cadence, and ask for one tight package: five name candidates, an 80-word About that leads with value, a banner tagline that fits YouTube’s 1546×423 px safe area, and a 30-second channel-trailer script. AI is strong at the copy; it is bad at picking the final name (taste, handle availability, trademark). Use the prompt below, then run the winner through YouTube’s handle checker and a trademark search before you commit.
Why the channel page is the conversion point, not the video
When a new viewer finds one of your videos and wants to know “who is this,” they click your channel name. What loads is the channel page: banner, handle, the first line or two of your About, and — for anyone not yet subscribed — your channel trailer auto-playing in the header. (Subscribers see a featured video instead.) That single page decides whether they hit Subscribe or bounce. Generic positioning like “Topic with [Name]” burns the moment.
Three of those elements have hard constraints you should design to, not against:
| Element | Constraint (as of June 2026) | What it means for your copy |
|---|---|---|
| Banner | Full canvas 2560×1440 px; safe area 1546×423 px displays on all devices; file under 6 MB | Put the tagline + logo inside the safe area or it crops on mobile |
| About / channel description | 1,000 characters max; only the first ~100–120 show in the hover preview | Front-load the value sentence; it is your real first impression |
| Handle (@-name) | 3–30 characters, letters/numbers plus . - _ (not at the start/end); must be unique; changeable twice per 14 days | Check availability before you fall in love with a name |
| Channel trailer | Auto-plays muted on mobile (70%+ of views); 25–45 s converts best for new visitors | Open with an on-screen hook; do not rely on audio |

When AI helps — and when it does not
AI is excellent at generating name candidates, restructuring the About around what viewers get rather than what you cover, and drafting a trailer script with a real hook. It is poor at three things, all of which you must own:
- Picking the final name. That is a taste, handle-availability, and trademark decision. AI cannot see the live handle registry.
- Verifying availability. Run candidates through YouTube’s signup/handle field, plus Instagram, TikTok, X, and a USPTO trademark search before committing.
- Knowing your real cadence. Never let the model promise a posting rhythm you cannot keep.
What to feed the AI
Vague input produces a generic “Topic with [Name].” Give it:
- Channel topic — specific (“Blender hard-surface modeling for game artists,” not “3D”)
- Audience and what they currently watch
- Posting cadence you can actually keep
- What makes you distinct (real, not aspirational)
- Brand voice and banned tics
- Name preference: real name, pseudonym, or both options
Copy-ready prompt
Build YouTube channel positioning. Be specific, no filler.
Topic (specific): [line]
Audience: [line]
Posting cadence (realistic): [N videos/week]
What makes me distinct: [line]
Brand voice and banned tics: [list]
Name preference: [real name / pseudonym / both]
Return:
1. Five channel name candidates - short, memorable, available-feeling.
For each, give a possible @-handle (3-30 chars) and flag which are
likely to fail trademark or availability checks.
2. An About section under 600 characters - value-led (what viewers get),
not a topic list. Put the single strongest value sentence FIRST so it
survives the 100-character hover preview.
3. Banner tagline - 8 words or fewer, earns the next click. Must read at
a glance inside a 1546x423 safe area.
4. A 30-second channel-trailer script (auto-plays muted for non-subscribers):
- First 5 seconds: visual hook that works WITHOUT sound (on-screen text)
- Next 18 seconds: what the channel does, for whom, why you
- Final 7 seconds: subscribe ask + what to expect and how often
5. End-screen CTA copy (subscribe + watch-next).
6. Three "do not say" - clichés to avoid in this exact niche.
Rules: Do not use "Topic with [Name]." Do not promise daily posting unless
I said I can. Captions/on-screen text must carry the trailer with sound off.For monetization-focused channels, append: “Add a lead-magnet position — what free resource to offer in the banner and About, and the one line that pitches it.”
Which model to use
This is a short-copy, taste-sensitive task, so any current flagship handles it. As of June 2026:
| Model | Why for this task | Plan |
|---|---|---|
| Claude Sonnet 4.6 | Tightest at “value-led, no filler” copy; good at killing clichés on request | Claude Free (limited) / Pro $20/mo |
| GPT-5.5 (Thinking) | Strong at varied name candidates and on-screen-text trailer beats | ChatGPT Free / Plus $20/mo |
| Gemini 3.1 Pro | Useful if you also want it to reason over your existing video titles for naming | Google AI Pro $19.99/mo |
Run the same prompt through two of them and steal the best name candidates and the cleanest About from each. For a deeper assistant comparison, see ChatGPT vs Claude vs Gemini.
How to check the output is usable
- Each name candidate is short, pronounceable, and you have checked the @-handle
- The About leads with value in the first sentence (it is all the preview shows)
- The banner tagline reads at a glance and fits the safe area
- The trailer script is 25–45 seconds at video pace and works with sound off
- The “do not say” list actually matches your niche, not generic advice
Common mistakes
- “Topic with [Name]” as the channel name — burns SEO and memorability
- About that lists topics instead of the value a viewer gets
- No cadence promise — viewers subscribe to a rhythm, not a one-off
- A trailer that summarizes the channel instead of hooking in the first 5 seconds
- Audio-dependent trailer — it auto-plays muted on mobile, where most views are
- Tagline outside the safe area — it crops on phones
- Skipping the handle/trademark check before committing to a name
When to do this for monetization
If the goal is the YouTube Partner Program, the channel page is also where you earn the subscribers that get you there. As of June 2026, YPP eligibility is 1,000 subscribers + 4,000 valid public watch hours in 12 months, or 1,000 subscribers + 10 million Shorts views in 90 days; an early-access tier opens features at 500 subscribers + 3,000 watch hours (or 3M Shorts views) in 90 days (YouTube Partner Program). A converting channel page is the cheapest way to move those numbers. Note that YouTube tightened enforcement against low-effort AI-generated content in 2026 — use AI to draft your positioning, then make videos worth subscribing to.
FAQ
- Same name across all platforms? Yes, if the handle is available everywhere. Cross-platform consistency compounds recognition. Check before you commit — you can only change a YouTube handle twice per 14 days.
- Should my face be on the banner? If you are the face of the channel, yes — recognition compounds. Keep it inside the 1546×423 safe area.
- Channel trailer or featured video as the pinned slot? Non-subscribers automatically see the trailer; subscribers see your featured video. Optimize the trailer for strangers and the featured video for fans.
- How often should I refresh the intro? Every ~90 days, driven by which videos actually performed — let your top performer reshape the About and tagline.
- Can AI just pick the name for me? No. It generates candidates; you verify the handle, trademark, and that it fits your voice. The model cannot see the live registry.
