Questions

What files can I chat with?+

PDFs, plus Word and PowerPoint files and plain text. Upload a single document or thousands at once, then ask questions across all of them.

How does it avoid wrong answers?+

Denser uses retrieval-augmented generation (RAG): it finds the exact passage in your document first, then answers from it and links the page. If the answer is not in your document, it says so instead of guessing.

Can I chat with multiple documents at once?+

Yes. Combine as many files as you need into one chat and ask across all of them at the same time, with each answer traced back to the file and page it came from.

How large a document can it handle?+

Denser indexes hundreds of thousands of pages and up to 50GB of documents, with three-layer retrieval that stays accurate even on very long files.

Does it show where the answer came from?+

Every answer links to the exact page. Click the citation to jump straight to the highlighted source in the document and verify it yourself.

Is my document data secure?+

Denser is SOC2 Type II certified. Data is encrypted in transit and at rest, and your documents are never used to train shared or foundation AI models.
