Reports, contracts, research papers, scanned forms — PDFs pile up faster than anyone can read them. PDF Summarizer exists to hand you the three minutes' worth of substance buried in a thirty-page document.
Most "AI summarizer" tools ask you to copy and paste text into a box — which means someone (or something) already had to open the PDF, extract the text cleanly, and hand it to you. That step is where most tools quietly fall apart, especially on scanned pages, multi-column layouts, or PDFs exported from old software.
We built our extraction pipeline to handle that first: it tries several extraction methods in sequence — a native PDF text parser, a command-line extractor, and an OCR pass for scanned or image-only pages — before ever calling an AI model. If your PDF is a phone-scanned contract or a photocopied form, we still try to read it.
Once we have clean text, we send it to a language model (Groq or OpenRouter, whichever responds fastest and stays up) with instructions for the length, format, and language you asked for. No proprietary-model marketing claims here — just a pipeline built to be reliable on real, messy documents.
None of this is marketing copy — it's the actual reasoning behind the pipeline.
We designed for real PDFs — scanned invoices, multi-column papers, exported reports — not clean pasted text. Extraction quality is the product, not an afterthought.
Both extraction (multiple methods, one file) and summarization (Groq, then OpenRouter, then a second OpenRouter account) fall back automatically. One provider having a bad day shouldn't mean your request fails.
Uploaded PDFs are processed in a temporary location and deleted immediately after text extraction — we don't build a library of your documents.
Free tier: 50 PDF summaries a month, no card required. Professional: $9/mo for 1,000. Business: $19/mo, unlimited. No hidden per-page surcharges.
No black box — this is roughly what happens between your upload and the summary.
HybridPDFExtractor
We try a native PDF parser first, fall back to a command-line text extractor, and if the page is mostly an image (a scan or photo), we run OCR. Whichever produces clean, usable text wins.
Groq → OpenRouter
The extracted text goes to a fast Groq-hosted model first; if that's unavailable, we retry against two independent OpenRouter accounts before giving up. You choose the length, format, style, and output language.
Web app or API
Use the web app for one-off documents, or call /api/summarize directly from your own code with an API key — same pipeline either way.
