Just Prompts

Just Prompts is a small, free web tool for refining AI prompts using a technique its creators call Additive Prompting. Rather than writing one prompt and hoping it works, the method is built around layering and adjusting a prompt in stages, refining wording and instructions as you go instead of starting over from scratch each time. The tool lets users save prompts they've built so they can reuse or revisit them later, and it connects to OpenAI's API using a key the user supplies themselves, meaning any usage costs are billed directly through the user's own OpenAI account rather than through Just Prompts. There is no sign-up requirement mentioned, keeping the barrier to trying it low. The site credits the Additive Prompting methodology to Twitter user @nickfloats and the tool itself to @SanxRoz, suggesting this is an independent or hobby project rather than a funded product. At the time of research, the page showed a loading animation and appeared to still be under active development, so some features may be incomplete or subject to change. No pricing, platform beyond the web, or company details are published.
