What are Open Semantic Search and Paperless-AI?
Open Semantic Search
Open Semantic Search is an open-source search engine and integrated text analytics suite for searching, monitoring, and analyzing large collections of documents. It supports OCR and entity extraction.
- Full-text and faceted search
- OCR of scanned documents
- Named entity extraction
- Document tagging
Paperless-AI
Paperless-AI is a companion service for Paperless-ngx that uses large language models to automatically analyze, tag, and categorize scanned documents. It connects to a Paperless-ngx instance and enriches documents with AI-generated metadata.
- AI-powered tagging
- Automatic categorization
- Paperless-ngx integration
- Document chat
