Header banner generated for @Y_DAO_com: a pixel-art letter Y in neon green and magenta on black — Generated for @Y_DAO_com from its own posts

The idea

Most profiles have a stock header. The posts underneath are far more interesting.

A header is the biggest image on a profile, and the hardest one to make. Designers are expensive, stock images say nothing, and generic AI art looks like everyone else’s.

YBanner reads what an account actually posts about, then draws from that. The result looks like the person, not like a template, and it is ready at the exact size X needs.

How it works

Four steps. About a minute.

01
Paste a handle
Any public X account: your own, your project’s, a friend’s.
02
AI reads the profile
Bio, recent posts and avatar are turned into topics, tone and a colour palette.
03
Four headers are drawn
Each one in a different style, at the exact 1500 × 500 size X uses.
04
Download or re-roll
One free re-roll is included. The banner is ready to upload as is.

Examples

Three accounts, six headers, zero templates.

The same tool, three very different profiles: a founder, a protocol and a community account. Each set was generated from the account’s own posts.

@CryptoYDao · Card Game Nights
@CryptoYDao · Rapper’s Studio
@PotBot_sol · Neon Vault Horizon
@PotBot_sol · 3D Liquid Core
@Y_DAO_com · Neon Lightning Horizon
@Y_DAO_com · Splat Void Wave

Why it works

Personal, profile-ready, paid onchain.

Made from what you post

No templates. Every banner starts from the account’s own topics, recurring images and inside jokes.

Fits the profile

The corner under the avatar stays clear and the palette is lifted from the avatar and posts.

Paid in Solana

USDC or SOL through Solana Pay. Connect a wallet to pay in one click and keep your balance on any device.

Under the hood

Built in a day on Solana rails.

The whole pipeline runs server-side: profile research and prompt writing by a language model, image generation by an image model, then an exact crop to X’s header size. Payments never touch a card.

Output: 4 banners at 1500 × 500, JPEG, avatar corner kept clear
Pricing: $3 for one generation, $5 for five. Each includes a free re-roll
Payments: Solana Pay in USDC or SOL; wallet sign-in with one-click pay
Stack: Next.js on Vercel, Supabase, xAI models, Wallet Standard
Feed: Every generated header joins a public feed (opt-out available)

Try it on your own handle.

One generation is $3. Four headers, a free re-roll, ready in about a minute.
