Weaviate enables direct chart retrieval from PDFs using image embeddings
CShorten30 · x · 2026-09-01
Weaviate has introduced a new late-interaction multi-vector retrieval method that eliminates the need to convert PDFs to text before searching.
Technical Highlights:
- Image Embeddings: Each PDF page is embedded as an image, allowing the retrieval of charts, tables, and layouts that text extraction often misses.
- Proven Results: Tested on 92 pages of NVIDIA investor decks, a query about automotive revenue successfully retrieved the exact five-quarter bar chart, even though the words "change" or "over time" did not appear on the page.
- Ease of Use: No OCR or chunking required; simply drag your PDFs into Weaviate Cloud to start querying.
