Comparisons

# ChatGPT vs Harvey

Harvey is built for legal work and names Finnish and EU legislation and case law among its sources; ChatGPT is a general assistant whose vendor names no Finnish or EU legal source. ChatGPT is easier to try, with a free plan and online purchase up to its Business plan, while Harvey is sold through its sales team without published prices. [1–9]

- **Last verified:** 21 October 2026

This verdict rests on public documentation and published benchmarks. We do not test ChatGPT or Harvey ourselves.

Our verdict

## Should you choose ChatGPT or Harvey?

Based on public documentation and published benchmarks: for research on Finnish and EU law, Harvey documents sources that ChatGPT does not, though neither documents Finnish preparatory works. On data handling the plans we score are close: both can store data in the EU, neither uses business data for training by default, and both list SOC 2 Type II, ISO/IEC 27001 and SAML single sign-on; in both, some processing may happen outside the chosen region. ChatGPT publishes prices for its personal and Business plans and has a free plan; Harvey publishes no prices, and its trials are limited evaluations. [1–26]

## When is ChatGPT or Harvey the better fit?

### Choose ChatGPT if…

- You want to start small: there is a free plan, and Go, Plus, Pro and Business can be bought online by card. [8]
- Your lawyers want an interface in Finnish. [27]
- You want one assistant for more than legal work, with plugins for Outlook, SharePoint, Teams and other services. [5]

#### ChatGPT is not for you if…

- You need research grounded in Finnish or EU legal sources: OpenAI names none for ChatGPT. [3–7]

### Choose Harvey if…

- You want research grounded in named Finnish and EU legislation and case law sources. [1,2]
- You review large document sets: Vault review tables extract and compare data points across thousands of documents. [28]
- You want contracts reviewed against your own standards and live negotiations compared with terms accepted in executed deals. [29]

#### Harvey is not for you if…

- You want published prices or online sign-up: Harvey's sales page shows neither. [9]
- Your team needs to work in Finnish throughout: Harvey does not name it as an interface or response language. [30,31]

### Neither suits you if…

- You rely on Finnish government proposals: neither documents them as a source. [1–4,6,10–14]
- Every request must be processed in the EU: both document exceptions, such as authentication and routing for ChatGPT, and web browsing and some subprocessors for Harvey. [16,23]

## What do you get with each?

Harvey is one platform of legal modules, among them agents, Vault, Knowledge research and Contract Intelligence, used in Word and Outlook and connected to iManage, NetDocuments and SharePoint. [34,35] ChatGPT is a general assistant with personal and business plans, and its Word add-in works on every plan. [8,36] A firm choosing between them is choosing between a tool built around legal work and one that it adapts to legal work itself.

## How do they handle client data?

Harvey stores customer data in the region named on the order form, which can be the EU, but some features may process data outside it, and its DPA allows transfers to the US unless the parties agree otherwise. [15,21,23,37] OpenAI offers storage in Europe to eligible new Enterprise customers, signs a DPA for Business and Enterprise, and has customers in the EEA contract with OpenAI Ireland. [16,18,38,39]

## How do ChatGPT and Harvey score on our rubric?

Both tools are scored on the same rubric. Three criteria rest on published benchmarks, some of them estimates.

## What else do lawyers ask about ChatGPT and Harvey?

### Can I use Harvey from ChatGPT?

Harvey appears among the legal plugins in OpenAI's plugin directory, and Harvey's own MCP server lets MCP clients query Harvey's legal Q&A, Vault and research sources. Each user signs in to Harvey and reaches only data they can view there. [7,32]

### Does Harvey run on OpenAI's models?

Among others: Harvey's subprocessor list names OpenAI alongside Anthropic, Mistral AI, Google Cloud Platform and other AI providers, and users can choose a model for complex matters. [31,33]

### Can we try them before buying?

ChatGPT has a free plan for everyone. Harvey's free trials run as authorised trials under its evaluation terms, which leave out features such as custom workflows, third-party integrations and certain research modules. [8,26]

### Do they work in Finnish?

ChatGPT's interface is available in Finnish. Harvey names French as an interface and response language, and English (UK), German, Italian and Portuguese for responses, but not Finnish. [27,30,31]
