Everything you need.
Nothing you don't.

Defendants bury documents deep in productions hoping you won't find them. Strata makes sure you do - without the enterprise price tag.

Boolean Search

Full Boolean syntax - AND, OR, NOT, exact phrases, wildcards, fuzzy matching, and proximity operators like W/10. Same logic as enterprise review platforms.

ESI Hit Reports

Generate formatted ESI hit reports as Excel or PDF, broken down by term, document, and page number - ready for motion practice, Golden Rule Letters, Motions to Compel, or production to opposing counsel.

Any File Type

PDF, DOCX, XLSX, CSV, EML, MSG, PPTX, TXT, and images via OCR. If it's in the production, Strata can search it.

Deposition Prep

Your co-working tool for depositions, Golden Rule Letters, Motions to Compel, and trial prep. Search by witness name or key terms, hand-pick responsive documents, and export a ZIP packet with a responsiveness log.

Redaction Scanner

Immediately see what the other side is holding back. Strata scans the entire production for redacted documents - mapping black bars and PDF redaction annotations by page - so you can quickly assess compliance or violation of the Court's orders.

Fully Local

Runs entirely on your computer - no cloud uploads, no SaaS subscriptions, no per-document charges. Your data stays on your machine.

Up and running
in minutes.

Upload any production in native format, index once, and search forever. No configuration, no IT involvement, no cloud.

Click Add Files or Add Folder to browse for documents. Strata accepts PDF, DOCX, XLSX, CSV, EML, MSG, PPTX, TXT, and images. Add the whole production folder at once.

Built for litigation.

I'm a paralegal at a busy plaintiff's side employment litigation firm. 30 active cases. Three trials in three months. I searched for a tool that could keep up and found the existing ones lacking or prohibitively expensive. So I built one. If you're in the litigation field, give it a try - and whether you have suggestions, bug reports, feature ideas, or just want to talk litigation, reach out. I'd love to hear from you.
