AI-powered app builders, code editors, and no-code platforms that let you create custom software, internal tools, and websites — no developer required.

Plurai lets you build evals and guardrails for your AI agents without any labeled training data. You describe your task, and Plurai generates a high-quality test set and trains a small language model (SLM) to evaluate your agent's outputs. Those SLMs run in under 100ms and cost 8x less than using a large model like GPT as a judge — making real-time guardrails affordable at production scale.
CatDoes is best for small business owners, founders, and non-technical people who want to build a mobile app or website without hiring a developer. You describe what you want in plain words, and an AI agent writes the code, runs tests, and fixes errors on its own. It can build iOS apps, Android apps, and websites — all with a backend (database, login, storage) included. You keep full ownership of your code and can export it or connect your GitHub account anytime.
Real workflows that save time for businesses using build with ai tools.
PrePrompt sits inside Cursor and intercepts every prompt your team types. It scores the request for clarity in under 1 ms, rewrites anything vague into a precise technical spec, and passes the improved version to your model. Your developers get better code on the first try without changing how they work.
Reduce AI re-prompting cycles by 60% and save 90 minutes of developer time per week.
Saves ~2 hrs/week
Describe the internal tool you need — a client status tracker, invoice dashboard, or project log — in plain English, and OpenAI Codex generates the full front-end and back-end code connected to your Supabase database. You deploy a working internal app in hours, not weeks, and skip a $5,000 to $15,000 developer bill.
Build a working internal tool in under 4 hours instead of 2 weeks and save $5,000 or more per tool on developer costs.
Saves ~4 hrs/week
You grab a community-built AI agent workflow from Epismo Hub that runs keyword research and competitor analysis. It connects to Mangools to pull real search data, then drops the results into a Notion page your team can act on. You skip hours of manual research and start with a proven process.
Cut SEO research time by 4 hours/week and get organized keyword reports your whole team can use.
