Prompto Quick Overview Video

Prompto, a blend of the word ‘Prompt’ and the Italian word ‘Pronto’ (meaning ready and quick), is aptly named as it allows for the quick and easy switching between different LLMs, directly from your browser.

Key Features:

  • Multi-LLM Support: Work with OLM, OpenAI, Anthropic, and Mistral LLMs (more to come!).
  • Flexible Interface: Use Prompto as a notebook for single prompts, a chat UI for conversation history, or save templates for frequent tasks.
  • Lightweight & Offline Ready: Runs entirely in the browser, saving your preferences locally for offline use.

Technical Details:

  • Built with Angular for a smooth user experience.
  • Utilizes LangChain.js for direct LLM interaction within the browser.
