Bring your own key · Real cost, no markup
Drop a video link or an idea. Fleekio writes the brief, keeps your likeness and composes YouTube, Shorts, TikTok and Instagram thumbnails with the AI models you choose.
The packaging problem
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
Most thumbnail tools resell AI at a markup and pick the model for you. Fleekio is the studio around the model, not a middleman taking a cut.
Bring your own key
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.
Your avatar
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.
Any reference
Paste the link of a thumbnail that works in your niche. Fleekio reads its composition and style, then rebuilds it with your face, your topic and your text.
How it works
Paste a YouTube, TikTok or Instagram link, upload a file or just type your idea. The transcript is condensed into a brief.
Add a few photos once. Your avatar and its expressions are reused in every project.
Pick a layout or a reference, or sketch the composition. Get several variants, with the estimated cost shown before you click.
Change an expression, fix one area, edit the text, ask for an AI review. Then export, with titles that match the thumbnail.
Every format
Generate at the exact size each platform expects. No more cropping a 16:9 image into a vertical cover and hoping the face survives.
1280 × 720 · 16:9
For long-form videos, with text that stays readable down to the Up next sidebar.
1080 × 1920 · 9:16
Vertical covers composed for the safe zones of each app.
1280 × 720 · 16:9
Objects, scenes and bold typography for channels that never show a face.
1024 × 1024 · 1:1
15 styles, previewed in the round crop your audience will see.
Edit without starting over
The editor works on the image you already like. Outside the area you select, the thumbnail stays identical, pixel for pixel.

FAQ
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.
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 nothing on top: no credit packs, no markup.
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.
Yes: 10 free generations to try the studio, no credit card required. Fleekio charges nothing for them, but like the subscription, the trial runs on your own API key, so your provider bills each generation at cost. The trial is one-time and does not renew. After that, the Creator plan is €10 per month.
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.
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.
Yes. Use any thumbnail as a reference, by link or upload: Fleekio reads its composition and applies it to your topic and your face. For a close remake, switch to Replicate mode. Use references as inspiration and respect other creators' work.
