Relativity aiR
Generative AI, seamlessly built into RelativityOne.
Overview
Relativity is one of the most established platforms in eDiscovery, and aiR is its answer to the wave of generative-AI-assisted review tools that have hit the legal tech market. Because it's built natively into RelativityOne rather than bolted on as a third-party plug-in, aiR benefits from direct access to the platform's existing document indexing, workflows, and security model — a meaningful advantage for large firms and corporate legal departments who don't want another vendor touching sensitive case data. As of early 2026, Relativity has bundled aiR for Review, aiR for Privilege, and aiR for Case Strategy into the standard RelativityOne package at no extra licensing fee, which is a notable shift from its original paid add-on model.
The tradeoff is that aiR is only available to organizations already committed to RelativityOne — this isn't a standalone tool you can adopt independently, and switching eDiscovery platforms just to get aiR wouldn't make sense for most teams. Pricing complexity is also a real concern: some contract structures still bill per document processed by the AI, and because billing is based on token-adjusted size (a long document can count as multiple 'docs'), costs can be harder to forecast than they first appear. Firms evaluating aiR should push their Relativity rep for the fixed-fee GB pricing model, which is more predictable for high-volume review projects. Competitors worth comparing include Reveal, DISCO, and Everlaw, all of which have their own generative AI review layers.
Key Features
aiR for Review: Uses generative AI to identify relevant documents faster than traditional review workflows, surfacing what matters in large document sets.
aiR for Privilege: Flags privileged material and helps prevent inadvertent disclosures and clawback situations during review.
aiR for Case Strategy: Helps litigation teams synthesize findings across a document set into a coherent case narrative.
aiR Assist: A conversational AI layer that lets users ask natural-language questions of their legal data and get instant answers.
Native platform integration: All aiR tools run inside RelativityOne itself, so there's no separate tool to license, deploy, or move data into.
Fixed-fee GB pricing option: As of late 2025, Relativity introduced an all-inclusive, unlimited-usage pricing model billed per gigabyte for clients who want cost predictability over per-document billing.
Pricing
Starting price
Custom pricing only, contact sales (aiR for Review, Privilege, and Case Strategy are bundled into standard RelativityOne subscriptions at no extra charge; per-document AI charges of roughly $0.20-$0.25/doc apply in some contract structures)
Bundled with RelativityOne: aiR for Review, aiR for Privilege, and aiR for Case Strategy are now included in standard RelativityOne subscriptions at no additional license fee.
Per-document billing (legacy/some contracts): Roughly $0.20-$0.25 per document processed by AI, based on token-adjusted document size, in certain contract structures.
Fixed-fee per-GB model: An unlimited-usage, all-inclusive pricing option billed per gigabyte, introduced in late 2025 for predictable-cost clients.
Enterprise custom quotes: Overall RelativityOne contracts (which aiR rides on top of) are negotiated individually; exact figures aren't published.
Disclaimer: pricing may change, confirm on Relativity's own pricing page before buying.
Pros
Native integration: Runs inside RelativityOne with no separate data migration or new vendor relationship required.
Now bundled at no extra cost: Core aiR products are included in standard RelativityOne pricing as of 2026, lowering the barrier to trying them.
Purpose-built for litigation workflows: Privilege review and case strategy tools address specific, high-stakes legal tasks rather than generic document summarization.
Established platform trust: Relativity is a long-standing industry standard, which matters for firms with strict data-handling and defensibility requirements.
Cons
RelativityOne lock-in: Only usable by existing RelativityOne customers, not a standalone product.
Pricing complexity: Some billing structures still use per-document, token-adjusted pricing that's hard to forecast on large or document-heavy matters.
Enterprise-only sales motion: No self-serve signup or transparent published pricing; everything goes through a sales conversation.
What Makes It Unique
Unique Angle: Unlike standalone AI review tools, aiR is deeply embedded in the market-leading RelativityOne platform, giving it access to workflows, security certifications, and defensibility processes that a bolt-on AI tool can't easily replicate.
