The discovery problem
What manual discovery review actually costs you
Weeks of reading. Billable hours lost to document hunting. No audit trail. Scanned PDFs that can't even be searched.
Weeks spent reading what you could search
A 150-document discovery pile means 150 separate reading sessions to find every mention of a key fact. Manual extraction is slow, error-prone, and impossible to cross-reference at scale.
Billable hours lost to document hunting
Searching for contradictions across depositions means re-reading each transcript multiple times, manually tracking references. Junior associates and paralegals spend entire days on tasks that don't require legal judgment.
No way to verify what you might have missed
Manual review leaves you wondering whether you caught every relevant passage. No audit trail, no systematic search log, no confidence that the extraction is complete. Professional risk isn't just time - it's the uncertainty.
Scanned PDFs that can't be searched
Older discovery materials arrive as image-based PDFs with no searchable text layer. Standard tools can't read them - you're back to manual page-by-page review. Legacy case files become inaccessible black boxes.
Core capabilities for legal workflows
Built for the work legal database tools don't handle
Cross-document contradiction detection. Multi-jurisdiction surveys. Deposition analysis at page-and-line precision. Discovery review at scale.
Cross-document contradiction detection
Ask where depositions contradict each other. Get cited answers surfacing conflicts across the entire pile. Otio shows you the contradictions — the legal judgment stays with you.
Multi-jurisdiction research
Upload materials from all 50 states and query across them simultaneously. First draft of the 50-state survey in a fraction of the time, every claim cited back to source.
Deposition and transcript analysis
Summarise key testimony, extract specific facts, cite to page and line. Pull related passages and verify every reference before you use it. Page-and-line precision built in.
Scanned PDF + legacy docs (Datalab OCR)
Image-based PDFs get OCR processing through Datalab. Older case materials become searchable and citeable just like native PDFs. Legacy files integrate automatically.
How it works for legal research
The discovery pile, searchable and cited to page and line
Upload your case materials. Ask across the entire pile. Verify every citation before it leaves your desk.
1
Upload unlimited case materials
Discovery responses, depositions, expert reports, correspondence. Upload 100, 150, 200 files. Scanned PDFs get OCR via Datalab so legacy materials become searchable.
2
Ask questions across the entire pile
One query searches every uploaded document simultaneously. Ask what the depositions say, where expert reports contradict, which documents support a specific claim. Days of reading become minutes.
3
Verify every citation before you use it
Every answer cites the document name, page number, and direct passage. Click any citation to jump to the source. Nothing leaves your desk without your review. Legal judgment stays with you.
Different tools for different jobs
How Otio compares to Westlaw, Harvey, ChatGPT, and NotebookLM
Otio doesn't replace your legal database. It handles the discovery pile that database tools weren't designed for.
Vs Westlaw, LexisNexis, Harvey
Legal database search
Built for case law research, statutory analysis, brief drafting from legal databases. Strong for searching external legal content you don't bring. Otio is for the documents you already have — discovery, depositions, client materials. Different tools, different jobs.
Vs ChatGPT, Claude
General AI, no persistence, no verification
Useful for drafting but no persistent document storage, file upload caps, known citation hallucination. Legal professionals can't use AI outputs they can't verify. Otio stores your documents permanently and cites every answer to the exact source.
Vs NotebookLM
Source-grounded but file-capped at 50
Strong source-grounded analysis, but 50-source cap is a real constraint for discovery-heavy matters. Large case files exceed the limit quickly. Otio handles unlimited documents with the same citation precision — 100, 150, 200 files in one matter.
Security and professional standards
Your case materials stay confidential and verifiable
Discovery files, depositions, client materials. Otio works with your sources, not around them. Source-grounded answers, page-and-line citations, no model training on your documents. Professional responsibility stays with you.
Answers only from your uploaded materials. Tells you when something isn't there rather than inventing case citations or page numbers.
Your documents, your control
Case materials stay in your workspace. Not used to train models. Not shared with third parties. You control what gets uploaded and when documents are removed.
Click any citation to jump to the source passage. Review the original context. Make the professional judgment about whether to use it. Nothing gets signed without your review.
Otio doesn't generate legal advice, conclusions, or court-ready outputs. It searches, extracts, synthesises from your uploaded materials. Legal analysis stays with you.

What our users say
@otio is really an excellent tool for understanding my papers. It is just like my personal librarian for the internet!

Neuroscience PhD
I took a 2 hour YouTube video and had the AI in Otio summarise it. I then asked follow-up questions about the highlighted pieces that got my attention. All told, I was able to collect key takeaways in less than 10 mins. Amazing.

I was fed up fighting with ChatGPT every time I wanted to do a deep dive on a library of research papers I had collected. It's the small things that made me switch - can't recommend it enough.

Is Otio a legal research database like Westlaw or LexisNexis?
No. Westlaw and LexisNexis are built for case law and statutory research from legal databases. Otio analyses the lawyer's own uploaded documents — discovery files, depositions, client correspondence. Use Westlaw for case law research, Otio for the discovery pile that results.
