Guided Path Pick one route and ThumbFlo will highlight the next click. Use Demo to learn, Upload when you have a StreamYard export, or Finish when a candidate is ready.
  1. Video: MP4, MOV, or WebM. StreamYard private links need an exported download.
  2. Inputs: add title first; face photos and photo sources are optional but stronger.
  3. No AI spend: use Recommended Setup, Check Inputs, Sample Flow, Today Check, or Create No-AI Draft PNG.
  4. Real run: Generate Top 3 creates Shock Face, Big Number, and Before/After AI choices for the same thumbnail/source.
How To Use Today Start with a StreamYard export or test the sample. Upload MP4/MOV/WebM, keep Generate Top 3 selected, then pick Shock, Big Number, or Before/After.
Creator proof not run yet. Checks Ready PNG, launch packet, spend safety, and the 3-choice path without spending AI.
Safe Start not run yet. Checks title, video/source, AI wallet, and whether the next run is prompt-only or source-guided without spending AI.
Competitor Choice Strategy 3 choices for one video/person. Competitors focus on fast useful options, not a crowded board. ThumbFlo keeps the creator on three clear paths: emotion, proof, and transformation. Why not 12? More choices slow the decision and raise AI cost. The goal is one winning upload-ready thumbnail from 3 strong AI options.

Tell ThumbFlo What To Make Describe your thumbnail idea by typing it or saying it. Use normal words: what should be on screen, where your face goes, the emotion, colors, text, overlays, and the main promise. ThumbFlo sends this into the AI prompt before the 3-image run.
Ready for a typed or spoken thumbnail idea. This becomes part of the AI prompt.
AI prompt preview Waiting for your thumbnail idea. Say or write the image, face placement, colors, text, and emotion you want.
Text Assistant Turn the idea into thumbnail words. No AI spend. Get 3 hook/callout options, apply one, then Generate Top 3.
Choose a look Pick one clear thumbnail direction. These five looks are the fast choices. Pick one, then generate your three finished thumbnail choices.
No Upload Start Make a thumbnail from text, saved face, photos, or a photo source. Video is optional. Title-only works with confirmation; saved face/photos/reference are stronger AI sources.
Always available: no video upload is required to start a 3-choice thumbnail run.
My Saved Face Photos Save up to 10 clean reaction faces. Reusable reaction photos live here. Use these in addition to the uploaded video frame. Pick one active face for the current thumbnail.
Overlay / Style Library Choose many styles, generate only 3 AI candidates. These are style directions for the three outputs, not extra AI images. Pick one before Generate Top 3.
Source Gate Waiting for title, video, or reference. ThumbFlo will show whether this run is idea-only or video-backed.
AI Input Readiness Prompt-only until a source asset is attached. Add an exported video, face, or photo source for source-guided thumbnail generation.
Today Check Find out if this project can become a thumbnail today. Runs readiness, handoff, and launch packet checks without spending AI credits.
3 real AI images / top run Ready to generate Generate Top 3 is the normal creator run. This run will spend 3 real AI images and show 3 strong choices for the same thumbnail/source.
