The packaging problem

Your video is good. The thumbnail decides if anyone sees it.

On a crowded home feed you get a fraction of a second. A generic stock image or a rushed Canva export loses the click before your title is even read. Great thumbnails used to mean hours of design or a freelancer on retainer.

Why Fleekio

Three things no credit pack will give you

Most thumbnail tools resell AI at a markup and decide the model for you. Fleekio is the studio around the model, not a middleman on top of it.

Bring your own key

Pay your AI provider at cost

Plug in your OpenAI, Google, Black Forest Labs, fal.ai or Replicate key. Choose the model for each step, and see the real cost of every run, logged at call time.

  • No credits, no markup
  • A model per pipeline step
  • Keys encrypted, write-only

Your avatar

A character that actually looks like you

Guided photo slots (front, three-quarter, full body and six expressions) build an avatar the models can follow. Shocked, curious, excited: your real face, not a lookalike.

  • 6 expressions from your photos
  • Several people per thumbnail
  • Consent required, no celebrities

Any reference

Borrow the vibe of any thumbnail

Paste the link of a thumbnail that works in your niche. Fleekio reads its composition and style and rebuilds it with your face, your topic and your text.

  • Any YouTube URL or upload
  • Replicate mode for close remakes
  • A library of proven layouts

How it works

From video to published thumbnail in four steps

  1. 01

    Start from your video

    Paste a YouTube, TikTok or Instagram link, upload a file or just type your idea. The transcript is condensed into a brief.

  2. 02

    Create your character

    Add a few photos once. Your avatar and its expressions are reused in every project.

  3. 03

    Generate your variants

    Pick a layout, a reference or sketch the composition. Get several variants with a cost estimate before you click.

  4. 04

    Retouch, then publish

    Change an expression, fix one area, edit the text, get an AI review. Then export and write titles that match.

Every format

One idea, every feed

Generate at the exact size each platform expects. No cropping a 16:9 image into a vertical cover and hoping the face survives.

FAQ

Questions, answered

What is Fleekio?

Fleekio is an AI thumbnail maker for YouTube, Shorts, TikTok and Instagram. It turns a video or an idea into a brief, keeps your face consistent through an avatar, and generates thumbnails with the AI models you connect.

What does bring your own key mean?

You connect your own API key from a provider such as OpenAI, Google, Black Forest Labs, fal.ai or Replicate. Generations are billed by that provider at their public price. Fleekio adds no credits and no markup on top.

How much does one thumbnail really cost?

It depends on the model you choose. In our own tests with OpenAI image models, one generation cost between about $0.05 and $0.11 at the provider, around $0.08 on average. Fleekio shows the estimated cost before you generate and the real cost after.

Is there a free trial?

Yes. You get 10 free generations to try the studio, with no credit card. Like every plan, the trial runs on your own AI API key: each generation is billed at cost by your provider. Trial credits are used once and do not renew. After that, the plan is €10 per month.

Which sizes and platforms are supported?

YouTube thumbnails at 1280 × 720 (16:9), vertical covers for Shorts, TikTok and Instagram Reels at 1080 × 1920 (9:16), faceless thumbnails, and profile pictures at 1024 × 1024.

Can I use my own face?

Yes. You add your own photos in guided slots, including six expressions, and Fleekio uses them as references. You must confirm you have the right to use each image, and photos of celebrities are not allowed.

Can I recreate a thumbnail I like?

You can use any thumbnail as a style reference, by link or upload. Fleekio reads its composition and applies it to your topic and your face. Use references for inspiration and respect other creators' work.

Are my API keys safe?

Keys are encrypted with AES-256-GCM and are write-only: once saved, only their last four characters are ever displayed, and they are never sent back to the browser.
