Preflight
Catch blind spots and organize your prompts before sending
Most prompts are incomplete — you only realize it after getting a bad answer. Preflight sits in your AI chat input and thinks alongside you before you hit send. It spots blind spots as you type, organizes scattered thoughts in one click, and detects when your prompt is really two tasks — splitting it automatically so the AI handles each part better. Works with ChatGPT, Claude, Gemini and more.
Maker here. I built Preflight because of one frustrating pattern I kept noticing: I'd write a long prompt, hit enter, and then realize I forgot to mention the format I wanted, the context the model needed, or that I'd crammed three different requests into one message. The result was always a back-and-forth that wasted my time.
Most prompt tools wait until you're done, then rewrite everything into one "perfect" prompt. Preflight works while you type — catching blind spots first, and only reshaping your words when you ask it to.
Preflight is like a "preflight check" for your AI prompts. It lives right inside the chat box and, as you type, it:
Catches blind spots — flags missing context or details before you send
Organizes your thoughts — turns a messy brain-dump into a clear prompt with one shortcut
Splits complex requests — suggests breaking an overloaded message into smarter, sequential steps
It works on ChatGPT, Claude, Gemini, Kimi, Qwen and some more other AI chats — no copy-pasting into a separate tool, no new tab. Just better prompts where you already work.
It's free to try (Google sign-in, 200 times analyse + 20 times organise / 5 hrs / account), and I'd genuinely love your feedback — what's the most annoying prompt mistake you keep making? I'm reading every comment today. 🙏
