The problem with cloud OCR

You're uploading privileged documents to someone else's server to get searchable text.

Cloud OCR means your documents sit on a third party's hardware, subject to their retention policies, their breach surface, and their bill. For litigation work, that's the worst place to put them.

  • Confidentiality exposure.Client documents move through a vendor's pipeline. Even with NDAs, that's a chain-of-custody hole you can't close.
  • Per-page pricing that never ends.Every production cycle gets metered. A single depo binder can quietly burn hundreds of dollars in OCR fees.
  • Upload queues on deadline.A 20 GB batch takes the evening to upload before recognition even starts. Tomorrow's filing doesn't care.
  • Loadfiles you still have to fix.Most cloud OCR outputs need re-keying before Relativity will ingest them. The "done" file isn't actually done.
VisionBlitz vs Cloud OCR

Same result. Fundamentally different posture.

Every row is a decision a partner or GC will ask about. Here's how the two approaches actually compare.

What it actually does

Built around the shape of a litigation deadline.

Three things, executed well. No account, no dashboard, no plugin ecosystem. Just the OCR-to-loadfile pipeline a review team actually runs.

01

Drop a folder. Every file and every PDF page runs in parallel.

VisionBlitz schedules work across every CPU core on your machine. Multi-page PDFs get split into per-page tasks, so a 200-page deposition finishes in the time a single page would take on one thread. No queueing. No uploading. Processing starts the moment you drop.

02

Exports the exact loadfile your review platform expects.

Concordance DAT, CSV, and Opticon OPT with standard field names: DOCID, FILEPATH, TEXTPATH, PAGECOUNT. Windows line endings, sequential DOCIDs, TEXT and NATIVES directories alongside. Ingests cleanly into Relativity or any platform that reads Concordance.

03

Runs entirely on-device, on Apple Silicon or Intel.

Recognition is Apple's own Vision framework, the same engine that reads text in Photos. Sandboxed by macOS, zero network calls, zero telemetry, no account. The only thing it asks for is permission to read the folder you drop on it.

A quick look

One window. Everything you need.

Document list on the left, full preview with zoom and search on the right, live progress at the bottom. That's the whole app.

Predictable output

A clean folder you can hand off unchanged.

Every run creates a timestamped export folder with sequential DOCIDs, a TEXT/ directory, a NATIVES/ directory, and the loadfile itself. Drop the folder into Relativity, Everlaw, DISCO, Nuix, or any platform that reads Concordance. Nothing else to configure.

Questions we get asked

What partners, paralegals, and IT want to know.

If something here isn't clear, email support. A human replies.

Does any document or text leave my Mac?
No. VisionBlitz uses Apple's on-device Vision framework for OCR and has no outbound network code. The app is sandboxed and only asks for read/write access to the folders you explicitly open. No telemetry, no crash-reporting service, no account server.
How does the Relativity loadfile work?
Each export produces a Concordance-format loadfile.dat (or CSV) with standard fields: DOCID, FILEPATH, TEXTPATH, CUSTODIAN, PAGECOUNT. Alongside it you get a TEXT/ directory and a NATIVES/ directory. An Opticon-format .opt file can be generated at the same time. The folder can be dropped straight into Relativity's ingestion flow; paths are relative so the whole package is portable.
What file formats can it read?
PDF (including multi-page), TIFF (including multi-page), PNG, JPEG, BMP, GIF, and HEIC. Multi-page PDFs are split into per-page OCR tasks so they run in parallel instead of sequentially.
How accurate is Apple Vision for legal documents?
Apple Vision's text recognition is competitive with commercial cloud OCR on typed documents, contracts, and clean PDFs. It handles mixed-case headers, footnotes, and multi-column layouts. For heavily degraded scans, low-DPI faxes, and handwritten material, every OCR engine struggles. We recommend spot-checking with the preview before export. The sample files on this page are good candidates to judge for yourself.
Does it work on Intel Macs?
Yes. VisionBlitz is a Universal binary and ships for both Apple Silicon and Intel. Minimum OS is macOS 13.0 (Ventura). Apple Silicon runs faster because Vision uses the Neural Engine, but accuracy is identical on Intel.
What about larger firms? Is there a team or volume license?
We distribute exclusively through the Mac App Store at launch, which means Apple Business Manager / Apps & Books works for bulk purchasing. For IT-managed fleets, it can be deployed through MDM the same way any App Store app can.
What if OCR misreads something?
The TEXT/ output is plain UTF-8 text you can edit directly. There's no lock-in format. The preview panel shows the recognized text next to the source page with search highlighting, so you can verify critical strings before exporting.
Who makes VisionBlitz?
West River Data Systems. Built because the people making it were tired of uploading privileged documents to third-party servers. Support goes to a real inbox: support@westriversys.com.
