Easy to categorize documents and offers transparent view of documents
I found Relativity very useful because it's easy to categorize documents. If you get more complex litigation, like around 500,000 or 1,000,000 documents, it's easier to categorize them in Relativity. So, it's a more powerful tool for reviewing documents. I haven't faced any problems using Relativity yet. I found it very useful.

Straightforward installation, good support, and suitable for large pipelines
My past experience with the Nuix eDiscovery platform showed it was clunky when reviewing individual files and viewing folder structures. I wondered why we had to process in Nuix eDiscovery and then transfer to another review platform, this was a waste of time. I wish Nuix eDiscovery would have a comprehensive review platform in-house. I heard they have improved in this area, but our firm hasn't invested in it. Integrating the processing and review would make for a fantastic solution.

"I haven't seen anything on AI merging with Relativity."
"My past experience with the Nuix eDiscovery platform showed it was clunky when reviewing individual files and viewing folder structures. I wondered why we had to process in Nuix eDiscovery and then transfer to another review platform, this was a waste of time. I wish Nuix eDiscovery would have a comprehensive review platform in-house.
