# Prompto

Canonical: https://www.softwareadvice.co.uk/software/670339/Prompto

> Prompto is an open-source, web-based tool designed for developers, AI enthusiasts, and open-source contributors who want a straightforward way to interact with multiple large language models (LLMs) from a single browser interface — no backend or server setup required.

The software runs entirely in the browser and stores user preferences locally, making it usable offline. Source code is available on GitHub for those who prefer self-hosting.

Core features include multi-LLM support, with compatibility across Ollama, OpenAI, Anthropic, and Mistral providers. Users can switch between models quickly for comparison or task-specific work. The interface can be used in three modes: as a notebook for single prompts, a chat UI for managing conversation history, or a template manager for handling frequently used prompts. LLM interaction is handled directly within the browser using LangChain.js.

Prompto is free and open-source, making it accessible to individuals and small teams exploring AI tools without infrastructure costs. Because it requires no server-side component, setup time is minimal.

Support is available through the open-source community and the project's GitHub repository, where users can report issues, review documentation, and contribute to development.
