Claude vs ChatGPT: how to make the switch for your organisation

Decide why you're switching

Write down the reason before you compare anything. Common ones are the quality of writing or analysis for your kind of work, how well it connects to the tools you use, admin and data controls, or price per person.

If the reason is vague, run a short trial before committing. Switching costs time, and staying put is a valid outcome.

Compare them on your own work

Generic benchmarks won't tell you much. Pick ten real tasks your team does every week, such as drafting a client email, summarising a contract or analysing a spreadsheet, and run each one through both tools with the same instructions.

Have the people who do that work score the results blind. Also check the practical things: single sign-on, admin controls, whether your data is used for training on the business plans, connections to Microsoft 365 or Google Workspace, and the price per seat.

Take stock of what you'd be moving

Make a list of everything your team has built in the current tool: custom GPTs or projects, saved instructions, prompt libraries, shared files and any automations that use the API.

Export what you can. ChatGPT lets users export their data from settings. Save the instructions and knowledge files behind each custom GPT, because these are what you'll rebuild.

Rebuild, then pilot with one team

Recreate your most-used assistants in the new tool. In Claude, a Project with instructions and knowledge files covers most of what a custom GPT does. Test each one against the same examples you used in the comparison.

Then move one team first for two to four weeks. Collect what's missing, fix it, and write a one-page guide covering where things are now and what's changed.

Switch the rest and tidy up

Move the remaining teams with a short training session each, update your AI use policy with the new tool's name and data rules, and point any API automations at the new provider after testing.

Run both tools side by side for a month, then cancel the old seats once nobody has needed them. Keep the exported data somewhere safe in case you need to refer back.

Claude vs ChatGPT at a glance

Claude is made by Anthropic, a company founded by former OpenAI researchers. ChatGPT is made by OpenAI. Both are capable AI assistants that can write, summarise, analyse long documents, answer follow up questions and help with complex tasks. For most everyday business work, either tool will do a good job.

The differences that matter to a small business are usually practical rather than headline features. How does each one fit with the tools you already use? What do the admin controls look like? How do usage limits work on each plan? And which one do the people doing the actual work prefer once they've tried both?

Anthropic trains Claude with an approach it calls Constitutional AI, a set of written principles the model learns to follow. OpenAI has its own safety and training methods. Both companies publish material on how they handle safety and data, and it's worth reading the business terms for whichever tool you choose.

• Both tools offer free tiers, paid individual plans and business plans with admin controls.
• Both can work with files, long documents and connected apps such as Google Drive.
• Features change often, so check each provider's current plan pages before you decide. [Confirm current features for both before publishing.]

Where people often find Claude helpful

Many users like Claude's writing quality and tone for drafting, editing and long documents. Its large context window means you can give it lengthy contracts, reports or transcripts in one go. Claude Code, Anthropic's coding tool, is popular with developers. Projects let you keep instructions and knowledge files together for a team.

Where people often find ChatGPT helpful

ChatGPT has a wide set of built-in features, including image generation, voice, web browsing and a large library of custom GPTs. Many staff already know it from using ChatGPT at home, which can make adoption easier. It also connects to a broad range of apps and services.

ChatGPT vs Claude for business: plans and controls

For a business, the individual plans are rarely the right fit. ChatGPT Plus and Claude Pro are designed for one person. Claude Max and the higher ChatGPT tiers add more usage and priority access for power users. For a team, look at the business plans instead.

The Claude Team plan and ChatGPT's business plan both give you a shared workspace, central billing, admin controls and a commitment that your business data isn't used to train their models by default. Enterprise plans add features such as single sign-on, audit logs, longer data retention controls and dedicated support.

What to check on the Claude Team plan

Look at the minimum number of seats, the usage limits per person, whether standard and premium seats are available, which connectors are included and whether Claude Code access is part of the plan. [Confirm current Claude Team plan details.]

What to check on ChatGPT's business plans

Look at the same things: seat minimums, usage limits, which models are included, how custom GPTs are shared across the workspace, and what admin and data controls you get. [Confirm current ChatGPT Business plan details.]

Regulated industries and sensitive information

If you work in a regulated industry such as legal, finance or healthcare, check where data is processed, how long it's kept, and what your contract says about sensitive information. Make sure your AI use policy says what staff can and can't paste into either tool. In the UK, your obligations under UK GDPR apply whichever tool you choose.

How to switch from ChatGPT to Claude without losing work

If your comparison points to Claude, the switch itself is mostly about moving what your team has built. Here's the practical side of moving from ChatGPT to Claude. The same steps work in reverse if you're moving the other way.

Export data and chat history

In ChatGPT, go to Settings, then Data controls, and choose Export data. OpenAI emails a download link to a file containing your chat history. On a business workspace, check with your admin which export options are available. Keep the archive somewhere secure, because it may contain sensitive information.

Rebuild custom GPTs as Claude Projects

Open each custom GPT, copy its instructions and download its knowledge files. In Claude, create a Project, paste the instructions into the project's custom instructions and upload the files. Test it on the same examples you used before. Most simple custom GPTs move across in minutes. Ones that call external actions need more work.

Bring memory and preferences across

ChatGPT's memory holds facts about how each person likes to work. You can ask ChatGPT to list what it remembers, review that list, and then add the useful parts to Claude's memory or a project's instructions. Claude also offers ways of importing memory from other assistants. [Check current memory import options.] Review everything before you import it, so old or wrong details don't come with you.

Move API calls and automations

If any automations make API calls to OpenAI, they'll need new API keys and some prompt changes for Claude. Tools like Make, Zapier and n8n support both providers. Test each automation side by side before you switch it over, and watch costs for the first few weeks.

Is Claude good for small business?

Yes, and so is ChatGPT. The better question is which one suits the way your small business works. Claude for business works well for teams that do a lot of writing, reading long documents, analysis and coding. ChatGPT suits teams that want images, voice and a wide set of built-in tools in one place.

Many small businesses end up using one tool as the main assistant and keeping a single seat of the other for specific jobs. That's a reasonable outcome. What matters most is that your team knows how to use Claude or ChatGPT well, with good prompts, your own data and clear rules. AI on its own helps a bit. AI plus people who know the work plus your own data helps far more.

• Choose Claude if your trial shows it does better on your writing, long document and analysis tasks.
• Choose ChatGPT if your trial shows it suits your team's mix of tasks and the tools you depend on.
• Choose neither yet if your team isn't using AI regularly. Start with training and one workflow first.

Common mistakes when switching AI tools

Most failed switches go wrong for the same few reasons. Avoid these and the move will be much smoother.

• Switching because of a headline or a social media post, rather than a test on your own work.
• Forgetting the custom GPTs, saved prompts and automations people rely on every day.
• Moving everyone at once with no pilot team and no guide.
• Not checking usage limits, so heavy users hit a wall in week one.
• Not updating the AI use policy, so staff aren't sure what they can share.
• Trusting factual claims from either tool without checking. Both can get things wrong.
