Nano Prompt Studio: Native macOS AI image & video studio. BYOK, no subscription.

Hey Product Hunt! 👋 I'm Muhlis, a filmmaker from Munich with 17+ years in German TV (ZDF, ARD). Late last year I started experimenting with AI image and video generation for pre-visualization and concept art. The problem: every AI tool speaks "prompt engineer," not filmmaker. I don't want to type "masterpiece, ultra detailed, 8k." I want to say "close-up, 85mm, shallow depth of field, golden hour." So I built Nano Prompt Studio — a native macOS app where you select shot type, camera lens, lighting setup, and the app translates that into prompts the AI models understand. What makes it different: • BYOK (Bring Your Own Key) — no subscription, ever. $8.99 once, then only pay API costs. • Multi-provider: Gemini, Kling, Veo, Claude from one interface • Built for filmmakers: 20+ cinematic presets, camera controls, character consistency • Native Mac app (Apple Silicon) — no Electron, no browser tabs The cost angle: Midjourney is $10/month minimum. With BYOK, generating 100 images on Gemini costs roughly $0.50-2.00. I'd love your honest feedback — what features would you want to see next? Happy to answer any questions!
