Requirements & limits

The project is described as self-hosted and web-based. Its repository identifies the license as MIT.

  • The project supports OpenAI, Google Gemini and Mistral, as well as local models through an OpenAI-compatible API endpoint.
  • For local-model use, the README says the model should perform well at OCR and that results are not guaranteed.
  • Custom prompts, fields, categories and projects allow extraction and organization to be tailored to a workflow.
  • The README warns that the project is in early development and places responsibility for data quality and privacy on the user.
  • The README describes historical exchange-rate conversion, including support for 170-plus fiat currencies and 14 cryptocurrencies.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
