As answered by people managing CodeSignal and Inputo.app.
Inputo.app's answer:
Inputo.app's answer:
Non-technical founders and makers who have app or SaaS ideas but lack the coding skills or technical knowledge to start building. People who are great at identifying problems but get overwhelmed by the technical decisions involved in creating a product.
Inputo.app's answer:
DeepSeek AI (idea analysis and prompt generation), Supabase (authentication and database), Stripe (payments), PHP (backend API), HTML/CSS/JavaScript (frontend), Hostinger (hosting).
Inputo.app's answer:
Unlike other tools that focus on just one step (validation, or prompt generation, or market research), Inputo walks you through the entire journey — from raw idea to launch-ready prompt — in a single 7-step wizard. No other tool combines idea refinement, competitor analysis, feature prioritization, tech stack recommendation, and AI prompt generation in one flow.
Inputo.app's answer:
Most competitors only solve one piece of the puzzle. Validator tools don't generate prompts. Prompt generators don't validate your market. Inputo does everything in one place, designed specifically for non-technical users who don't know where to start. You go from idea to buildable prompt in about 10 minutes.
Inputo.app's answer:
Inputo was born from personal frustration. The founder constantly had app ideas but would get stuck on the same questions: what features first, what tech stack, how to even start. The ideas would die in his head. So he built the tool he wished existed — a wizard that makes all those decisions for you and hands you a prompt you can paste into an AI builder.
