AI prompt optimizer for the power industry: DC power, batteries, UPS and renewables.

Who is PromptFix best for?

PromptFix is best for engineers in DC power, batteries and renewables who want their AI prompts scored and rewritten.

  • Power and energy engineers

    Its templates cover DC power, battery systems, UPS and renewable energy, and its rewrites draw on standards such as IEEE 485, NEBS and Telcordia.

    Each prompt gets an AI score and a suggested rewrite, and you can compare variations before saving the best one to your library.

  • Wiring prompts into other tools

    Pro and Business add API keys, webhooks and saved workflows, so optimizations can run from your own software.

  • Small technical teams

    Business includes 5 users, unlimited saved prompts, SSO and an audit log, and each extra seat costs $5 a month.
