Show HN: Collate – Offline AI PDF reader and chat for Mac (private, on-device)

Collate – Offline AI PDF reader and chat for Mac (private, on-device) is active in the show hn launch space.

Profile

I built Collate, a free Mac app that summarizes and chats with PDFs entirely on your device. No uploads, no rate limits, just open a file and ask questions. It highlights the exact passages it used and shows citations, so you can verify answers quickly.Why: I wanted AI that feels like a normal app—fast, private, and not tethered to a cloud account—especially for long papers and reports.How it works (high level): • Extracts text with native macOS frameworks (works best with text-based PDFs). • Chunks + indexes the doc locally for retrieval. • Runs a small LLM on Apple Silicon using on-device inference. • Maps answers back to page spans and auto-highlights them.What’s new: share clean summary

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

Its current recorded stage is Show HN launch.
