The document-upgrade API
The most searchable version
of every document you have.
Image-only scan or weak existing OCR — it doesn't matter. SearchLayerPDF runs every OCR engine, then uses AI to sift, compare, and synthesize the single most accurate text layer — wrapped in archival-grade PDF/A-3b. Point any search, RAG, or retrieval system at it and it gets better, instantly.
- Works on image-only scans and weak existing OCR
- Every engine + AI synthesis → maximum searchability
- Archival-grade PDF/A-3b · pay only for what we improve
- 8+ OCR engines synthesized per page More engines = more signal for AI synthesis
- 100+ Languages supported Including Arabic, Persian, Nastaliq, Ottoman
- 74% Documents on fast-path Already-good PDFs upgraded to archival format at no cost
- 0.061 Arabic character error rate Best-in-class on Arabic benchmarks
How it works
Three steps. Zero infrastructure changes.
Don't change your RAG pipeline. Upgrade the documents going into it.
-
Submit your PDF
Send any PDF via REST API, JavaScript SDK, CLI, or the portal. No configuration needed — the pipeline reads the document and decides what it needs.
-
Every engine runs. AI synthesizes.
Every relevant OCR engine processes each page at once. AI then sifts, compares, and synthesizes the correct text — not by voting for the most common answer, but by drawing the right reading from partial evidence across all of them at once.
-
Receive a searchable PDF
You get a PDF/A-3b with an accurate embedded text layer, plus structured Markdown with page references. Feed it straight into your RAG pipeline, vector store, or search index — your retrieval stack, unchanged.

Why we're more accurate than any single engine
Every competitor runs one engine.
We run them all — then sift, compare & synthesize.
AWS Textract, Google Document AI, Azure, ABBYY — each runs a single proprietary OCR model and returns its best guess. If the model gets it wrong, there's no recovery path. You get the error.
SearchLayerPDF runs every relevant engine on a page, then uses AI to sift, compare, and synthesize the correct text from all their outputs at once. One engine gets the vowels right, another the consonants — together they produce the correct word, even when neither does alone.
This is the same reason a panel of experts outperforms any individual expert. Every engine added to the ensemble gives the AI more signal to work from — growing the ensemble is our primary quality lever.
Everything your documents need. Nothing they don't.
Pay for improvement, not page volume
Every competitor charges per page regardless of outcome. We charge only for pages where the Retrievability Score actually improves. Already-good PDFs are detected and upgraded to archival format — at no cost.
Arabic, Persian, and Nastaliq specialist
Specialist Arabic & Persian recognition (character error rate ~0.061, beating leading OCR) with full Nastaliq calligraphic handling. No other OCR API positions specifically for RTL script quality.
GDPR-ready, HIPAA-adjacent privacy
Files deleted within 24 hours — automatic, not on request. No training data use. Fully automated pipeline with no human access. DPA available. Suitable for legally privileged and regulated content.
Verifiable Retrievability Score
Every page is scored 0–100 before and after processing. You get a complete audit trail: which engines ran, what each stage cost, and exactly what improved.
RAG-optimized output
Output is structured Markdown with PDF page references — ready for chunking, embedding, and retrieval. Not raw text dumps. Accurate input means better embeddings and better LLM answers.
Archival-grade PDF/A-3b output
Output conforms to PDF/A-3b with embedded text layer, visually identical to the original. Suitable for legal hold, government records, and long-term institutional preservation.
Built for regulated industries
Suitable for legally privileged,
GDPR-regulated, and sensitive content.
Most cloud OCR services process your documents on shared infrastructure with unclear data retention. SearchLayerPDF is built differently — the pipeline is fully automated, deletion is guaranteed, and no human ever has access to your content.
- Automatic 24-hour deletion Every file is deleted within 24 hours of job completion. Not archived, not backed up, not logged to a data lake. Automatic — no request needed.
- Zero human access Fully automated pipeline. No staff reviews documents, no manual QA, no exceptions. Attorney-client privilege and medical records stay private.
- No model training Your documents are never used to train or fine-tune models. Processing is strictly transient — input in, text out, files deleted.
- GDPR-ready, DPA available Data processing complies with GDPR requirements. Data Processing Agreement available for EU customers and regulated organizations.
