Notes from the demo run
AI-generatedWe signed into ThumblifyAI with Google and walked the /generate studio end-to-end. It greets you by name ("Let's make people click, Last.") and drops you straight into a prompt box with generation modes (Recreate, Style Match, Ultra Editing, Sketch to Thumbnail, Pro Thumbnails, Train AI) plus a Trending gallery — a genuinely fast path from sign-in to first thumbnail.
- Personalized studioThe studio addresses the user by first name and pre-loads a Trending inspiration wall, so a new signup has something to react to instead of a blank canvas.
- One free credit to tryThe Free plan ships with 1 credit visible in the composer, letting an evaluator generate once before hitting the paywall — a strong try-before-buy signal.
- "What's New" modal covers the studio on entryThe 2.2 changelog modal overlays the whole /generate surface on first load; a first-time user has to dismiss it before they can see the prompt box. Consider gating it to a small badge.
- Upgrade prompt sits above the first action"Free plan · Upgrade" renders directly over the composer greeting; leading with the single free credit before the upgrade nudge would soften the first impression.
