Show HN: Precog – Enhanced OCR + Agentic PDF analysis tools for highlighting txt

Hi HN,

We built Precog because current AI chatbots and platforms do not offer good PDF annotation tools to highlight and cite answers directly from uploaded PDFs.

Precog is great for draft revision, quote gathering, and source skimming. When chatting with Precog, Precog stays contextually locked to the information in the PDF added to the context window. Reference uploaded files, found sources, and analysis points using the @ symbol referencing (like Cursor). We have found that through @ symbol referencing in-prompt, hallucination is minimized, and as notes and interactions are made, the context awareness around the user's needs increases dramatically.

If you think this tool is helpful, I'd love your feedback and any questions, comments, or critiques.
