About just build things

Just Build Things is a browser-based creative and AI toolkit offering over 700 tools in a single interface. It combines AI-powered analysis, generation, and chat capabilities with a collection of standalone free utilities for design, development, music, finance, and more. The platform is designed for creators, developers, and hobbyists who want to go from idea to creation quickly without needing to install software or manage multiple subscriptions.

For AI features, users can analyze images, audio, video, and PDFs — extracting insights like style, emotion, scene summaries, and readability scores. Generation tools cover images (using models such as FLUX, Seedream, GPT Image, Imagen), video (Veo, Seedance, Wan, LTX), music and speech (ElevenLabs TTS, Whisper transcription), and even a 'vibe coder' that builds web applications from text descriptions. The AI writing and chat section includes over 200 templates, multiple AI personalities, flashcard generators, quizzes, and personality tests.

Beyond AI, the platform offers dozens of free, always-available tools that require no account, no daily caps, and no login. These include design utilities like color palette generators and pixel art creators, developer tools such as JSON formatters and UUID generators, music tools like guitar tuners and drum machines, plus games and other utilities. The entire toolkit is regularly updated with new tools shipped weekly, and users can search or browse by category to find exactly what they need.
