What is PromptForge?
The platform emphasizes zero-trust operations where all file handling, vector operations, and model calls occur within the user's browser environment. This setup allows direct routing to various language models while maintaining full control over credentials and outputs. Multiple integrated utilities address coding needs, business ideation through expert personas, platform-specific content generation, and web research with sourced results. Charts and reports generate on demand from uploaded data files. An interactive system mesh enables side-by-side model comparisons and dynamic prompt routing across backends. Saved contexts persist locally to support ongoing projects across different tools.
