Onna vs RelativityOne

Onna is a paid data collection and management platform for eDiscovery. It centralizes collaboration data in a searchable, defensible environment for preservation, targeted collection, searching, and export to downstream review tools. The platform advertises more than 29 no-code connectors, including Slack, Google Workspace, Microsoft 365, Zoom, Atlassian, Dropbox, Salesforce, and Zendesk, plus sources such as Teams, Box, SharePoint, Jira, GitHub, Miro, Quip, custom internal systems, and unsupported SaaS applications. Collections can run once or continuously, with most connectors pulling new or changed content automatically. Real-time indexing supports searches within minutes using custodian, channel, date, keyword, and file-type filters. In-place preservation can prevent deletion or modification while keeping an audit trail. Exports to Logikcull and Reveal retain conversation context and threading. Onna supports API, self-hosted, and web access, hybrid environments, vendor-cloud deployment, AES-256 encryption, role-based access, audit logs, and standard support.

RelativityOne is a vendor-cloud platform for legal work, including litigation, investigations, and other legal data challenges. It supports e-discovery from collection through production and review of emails, spreadsheets, chats, prompt-and-response conversations, and PDFs. Review tools include a native file viewer, email threading, and automated redaction; production options include TIFF, text, metadata, load files, and native files with placeholders. Administrators can manage permissions for users, system administrators, workspaces, and specific objects such as views, tabs, and fields. Security Center is included. Relativity says several AI capabilities are included with committed data volume, without separate AI licenses or per-user fees; other products, including Data Breach Response, Translate, FOIA, and Legal Hold, are licensed separately. Licensing is flexible: pay as you go or commit for one or three years, with pricing on request. The platform lists API, iOS, macOS, web, and Windows access, and customers can choose data location in 17 countries. Linux-based devices and mobile browsers are unsupported; mobile-device use requires the mobile app.
