Relativity Pricing: What RelativityOne and aiR Cost
Relativity does not publish a rate card. As of September 2026, its own pricing page says the platform is sold on a committed data volume, with three ways to pay: pay as you go, a one-year commitment, or a three-year commitment, and every route ends at "Request Pricing." Two things about that model matter more than any headline number. First, the AI is inside the price: aiR Review, aiR for Privilege, Case Strategy and Assist come with your data volume, with no separate AI licenses and no per-user fees. Second, the product you are pricing changed its name on 16 September 2026, when RelativityOne became Relativity aiR. Relativity has changed how it charges at least five times since 2019, so any per-GB figure, per-seat fee or per-document AI charge you find in an older review may describe a model that no longer exists. Below is what the current model bills for, the timeline of how it got here, and what that means for a small matter versus a large one.
This is software evaluation and industry analysis, not legal advice.
How does Relativity price RelativityOne today?
Start with the name. Relativity's September 2026 announcement says RelativityOne is now Relativity aiR, and that "aiR" was previously the name of the AI features running inside RelativityOne. It is the same cloud platform. If you are searching for RelativityOne pricing, you are looking for Relativity aiR pricing, and the vendor's own pages now use the new name.
The pricing page describes one commercial unit: data volume. The subscription covers the full data lifecycle, which the page lists as processing, analytics, Review Center, redaction, automated workflows, a native viewer, AV transcription, email thread visualization and near-duplicate detection. The AI features ride on the same volume commitment. A short list of add-ons is licensed separately: Data Breach Response, Translate, Relativity FOIA and Legal Hold. If your team never touches those workflows, they never appear on the bill.
What the pricing page does not show is the rate. For a more precise picture of what gets metered, Relativity's own Cost Explorer documentation is more useful than any marketing page, because it describes the fields that appear on an invoice:
| Billing line (from Relativity's Cost Explorer docs) | What it measures | Why it matters for your budget |
|---|---|---|
| Review tier | GB in active review workspaces | The expensive tier. Data sitting here after it stops being useful still costs you. |
| Repository tier | GB held for early case work, subject to usage limits | Cheaper storage, but breaking the repository usage limits reverts the calculation as if the data were in review. |
| Cold Storage tier | GB in archived workspaces | Where closed matters should go if you have to keep them. |
| Peak Day | The highest usage day in the billing period | You pay for the peak, not the average. A one-day spike sets the month. |
| Staging | Peak staging usage in GB | Data waiting to be processed is billable too. |
| Billable users | Users billable under your specific subscription | Current pricing says no per-user fees, but older contracts can still carry them. Check yours. |
| aiR Units | Successful AI analyses, not unique documents | Re-running a prompt counts again. Some subscriptions include units up to a threshold. |
Two lines in that table deserve attention before you sign. Peak Day billing means a matter that briefly loads a large collection and then culls it is billed at the high point for that period. And the aiR Unit count is not a unique document count: the documentation says each successful analysis, including a later re-run, adds to it. If your subscription includes aiR Units up to a threshold, ask where that threshold sits and what happens above it.
What has changed in Relativity's pricing, and when?
This is the part most pricing summaries skip, and it explains why older numbers mislead. Every change below comes from Relativity's own announcements or documentation.
| Date | What Relativity changed | Effect on small matters | Effect on large matters |
|---|---|---|---|
| January 2019 | Lowered RelativityOne prices by up to 60 percent, bundled unlimited analytics, introduced consumption-based billing | Analytics stopped being an extra line on a matter that could not justify it | Lower unit price on big collections; analytics no longer negotiated separately |
| February 2020 | Pay as you go (month to month, based on usage) and flex commit (discounts of up to 25 percent from pay-as-you-go rates) | First real way in without an upfront commitment | Commitment discounts became the lever for predictable volume |
| August 2022 | Separate user fees bundled into a single data fee | Adding co-counsel or a client reviewer stopped costing a seat | Large review teams and non-litigation users (breach, DSAR, investigations) stopped multiplying the bill |
| September 2024 | aiR Review metering moved from character-based Document Units to counted aiR Unit Analyses | Cost follows the number of AI analyses run rather than document length; every run counts | Iterating prompts across millions of documents became the cost driver to watch |
| October 2025 | aiR for Review and aiR for Privilege announced as included in standard pricing from early 2026 | AI review became available on matters that could never absorb a per-document charge | The separate AI line on large reviews went away |
| September 2026 | RelativityOne renamed Relativity aiR; AI capabilities stated as included in current pricing | Same model, new name to search for | Same model; add-ons still licensed separately |
The 2020 change is described in Relativity's own post introducing pay as you go for RelativityOne. The 2022 change is in the company's announcement that it would bundle user fees into a single data fee. The 2024 metering change is recorded in the Cost Explorer documentation. The October 2025 inclusion of aiR was reported by Above the Law from Relativity Fest, and the September 2026 rename announcement restates that AI is included.
Read the table as a direction of travel. Every change has moved cost away from things you count per person or per document and toward one number: how much data you hold, in which tier, at your peak. That is simpler to forecast than the old model. It also means data hygiene is now the biggest lever you control.
What does pay-as-you-go change for small matters?
Before 2020, RelativityOne was effectively a commitment purchase. Pay as you go changed that, and the current pricing page still offers it alongside the one-year and three-year options. For a small firm or a single matter, that is the difference between Relativity being possible and not.
What pay as you go does not do is make the platform cheap. It removes the upfront commitment; the per-GB rate is higher than a committed rate, which is the whole point of the commitment discount. The 2020 announcement put the flex commit discount at up to 25 percent off pay-as-you-go pricing. Relativity has not published whether that spread still applies under the current plans, so treat it as history, not a quote.
For a small matter, three things decide the bill more than the rate itself:
- How long the data stays in review. Move closed or culled data to repository or cold storage, or delete it, as soon as the case allows.
- Your peak. Loading an entire collection and culling it later sets a high Peak Day. Culling before promotion to review keeps the peak down.
- Who you buy through. Relativity sells through a network of channel partners and service providers as well as directly, and partners set their own pricing. Relativity's docs note that for instances bought through distributor partners, cost data fields in Cost Explorer are disabled, so your invoice comes from the partner, not from Relativity.
That last point is why a small firm often never talks to Relativity directly. The partner's pricing model, whether per GB, per matter or all-in, is the number that actually lands on your desk.
How is aiR priced on top of the platform?
As of September 2026, it is not priced on top. The pricing page lists Relativity claiR (marked "Coming Soon"), Assist, aiR Review, Privilege and Case Strategy as included with your committed data volume, with no separate AI licenses. The September 2026 announcement says the same: the AI is part of current pricing rather than a separate line item.
That was not always true. Before the October 2025 announcement, aiR for Review and aiR for Privilege were charged separately, which is why older forum threads and reviews talk about per-document AI costs. Partners built their own offers around that uncertainty. Cimplifi, for example, announced all-in, fixed-fee per-GB pricing for aiR for Review and aiR for Privilege in October 2025, specifically to remove the unpredictability of document-based charges.
Two caveats keep "included" from meaning "unlimited" in every contract. The Cost Explorer documentation still describes aiR Units and an aiR Unit Threshold for subscriptions that include aiR access, with costs shown as informational until usage exceeds that threshold. And contracts signed under earlier models do not rewrite themselves. If your renewal predates the change, ask in writing whether aiR usage is included, capped, or metered on your paper.
What do buyers report paying?
Here the honest answer is that verified public figures are thin, and the ones that exist come from partners and third parties rather than Relativity. These are reported figures, not Relativity's prices:
| Source | Reported figure or finding | How to read it |
|---|---|---|
| UK G-Cloud 14 listing for RelativityOne by partner Anexsys | £9 a gigabyte a month; no free trial | A partner's public-sector list price, including its own service layer. Not a Relativity rate. |
| An independent comparison site reviewing Relativity aiR (August 2026) | Indicative $11 to $13 per GB per month for the platform, while noting Relativity does not publish per-GB rates | An estimate, not a quote. Useful only as an order of magnitude. |
| Complete Discovery Source, a Relativity partner (May 2026) | Has seen a terabyte on Relativity Server land as roughly 700 GB after moving to the cloud platform | Your billable GB may be lower than your Server footprint, because Server counts indexes and database elements differently. |
| Review sites (TrustRadius, Software Advice) | No pricing plans listed | Confirms the quote-only model; no usable number. |
The spread between those figures is the point. A partner price bundles support and services; an estimate from a third party is a guess; a migration anecdote tells you your GB count may shrink. None of them is your price. The directory lists Relativity aiR as "Pricing on request" for the same reason.
When does a different platform cost less?
Relativity's model rewards teams that hold a lot of data, run many matters, and have someone managing tiers and peaks. It is least forgiving when data sits in review for a long time with nobody watching it. A different platform tends to cost less in three situations:
- One matter, long hosting, small team. The per-GB, peak-day model keeps billing while the case sits. A platform priced another way can be cheaper. In our directory, Nextpoint lists per-user pricing with unlimited data, which is the opposite trade: you pay for people, not gigabytes.
- No administrator. Relativity's configurability assumes a Relativity specialist or a partner running it. That labor is a cost, even if it never appears on the platform invoice. Our AI e-discovery software comparison covers the admin overhead difference with Everlaw and DISCO in detail.
- You need an add-on Relativity licenses separately. Breach response, translation, FOIA and legal hold sit outside the volume commitment. If one of those is your core workflow, price the add-on before you compare base rates.
Everlaw, DISCO and Relativity are all listed as "Pricing on request" in the directory, so no public rate settles the comparison. What does settle it is running the same matter profile past each vendor: expected GB at peak, months in active review, number of reviewers, and whether AI review is included on that exact contract. For how Relativity's pricing sits within the wider market, see our legal AI pricing guide. Relativity also bought Gavel in June 2026, which our acquisitions tracker follows; Gavel keeps its own published pricing for now.

FAQ
How much does RelativityOne cost per GB?
Relativity does not publish a per-GB rate. As of September 2026, pricing is based on committed data volume, paid as you go or through a one-year or three-year commitment, and quoted on request. Public figures come from partners and third parties, such as a partner's £9 per GB per month G-Cloud listing, and should be treated as reported, not as Relativity's price.
Does Relativity charge extra for aiR?
Not under current pricing. Relativity's pricing page lists aiR Review, Privilege, Case Strategy and Assist as included with your committed data volume, with no separate AI licenses. Older contracts and some subscriptions reference aiR Units and a usage threshold, so confirm what your own contract says.
Is Relativity affordable for small firms?
It can be, mostly through pay as you go or a partner who resells the platform with a per-matter or all-in price. The costs to watch are peak-day billing and data left in the review tier after it stops being needed. Small firms with long-running matters and no administrator often find a differently priced platform cheaper.
Is Everlaw cheaper than Relativity?
There is no public rate that answers this. Both are quote-based in our directory. The cheaper option depends on your data volume, how long matters stay hosted, how many people review, and which AI features are included on each contract. Get both quotes on the same matter profile and compare the totals, not the headline rates.
