Track prompts to results Your prompts live in 15 different places. PromptFolio connects them to the results they produced—across every platform, every variation. Stop losing your best work. You found a great prompt, tested it across three platforms, tweaked it a dozen times, and downloaded the results. Now you can't remember which version made which image—or even where you saved the original prompt. PromptFolio keeps the whole thread together. THE PROBLEM Screenshots in your camera roll. Notes scattered across apps. Discord history you'll never find again. That perfect prompt? Buried somewhere. And even if you find it, you can't remember which AI model produced which result—or what tweaks made the difference. You're experimenting across platforms, models, and tools. But there's no way to track what actually works. THE SOLUTION PromptFolio is a visual archive for AI image generation. Save prompts, attach the results they produced, and track which platform and settings delivered the best output. Over time, you build a searchable library of what works—organized, visual, and always with you. HOW IT WORKS - Save Your Work — Snap a screenshot, paste text, or type directly. OCR extracts prompts automatically. Takes seconds. - Experiment Across Platforms — Use your prompt in any AI image or video tool. Try variations. Compare results. - Track What Produced What — Attach generated images or videos from your Photos library. Record the platform, model, and settings. Rate your favorites. Add notes. - Build Your Library — Search by text, filter by model, browse visually. See at a glance which prompts delivered—and which approaches work best for you. SMART FEATURES Lexicon Suggestions — Already have a prompt? Turn on suggestions and PromptFolio highlights where professional terminology could improve it. Swap "dramatic shadows" for "chiaroscuro lighting" with a tap. Creative Vocabulary — Browse 70+ curated terms for lighting, composition, camera techniques, and artistic styles. Learn what creative descriptors actually look like, and add them to your prompts with a tap. Remix Without Risk — Want to experiment with a prompt without losing the original? Remix creates a linked variation so you can iterate freely and see how your prompts evolved. Compare Results — Attach multiple outputs to a single prompt. See exactly how Gemini interpreted it versus Flux versus Ideogram. Build real knowledge about what works where. WHAT PROMPTFOLIO IS *NOT* This app does not generate images. It doesn't connect to AI services or require API keys. It's purely a reference and organization tool—a place to collect the prompts and results you create elsewhere. DETAILS * Try free with up to 5 prompts, then unlock unlimited for $0.99—one time, forever * No subscription, no ads, no tracking * iCloud sync across iPhone and iPad * Images and videos reference your Photos library—no duplication, no extra storage * Works offline; syncs when connected * Built natively for iOS 26
