The right way to compare AI assistant prices is to separate individual subscriptions, managed team plans and API usage. They pay for different things. A low personal subscription is not automatically suitable for company data, central administration or unattended automation. Prices and plan names change, so verify the vendor's current official pricing before purchasing.
What should you compare?
- Individual plans: useful for personal evaluation, but check whether company use and data handling meet your policies.
- Team and business plans: compare minimum seats, annual versus monthly billing, admin controls, identity, data terms and support.
- Enterprise agreements: evaluate procurement, security, compliance, support and negotiated terms rather than comparing headline seat price alone.
- API pricing: usage-based charges depend on model, input/output volume, tools and workload. Do not treat API rates as a monthly subscription.
- Workflow and document tools: price the business process delivered, including integration, approvals, storage and per-document or execution fees.
The five assistant options
ChatGPT (OpenAI) is a broad general-purpose assistant with individual, business and enterprise routes. For a UK business, start with the official [ChatGPT pricing page](https://chatgpt.com/pricing/) and [OpenAI business information](https://openai.com/business/). AI Build can help eligible UK organisations evaluate ChatGPT Business and its rollout; see the partner offer.
Claude (Anthropic) offers individual and organisation-oriented plans as well as API access. Check [Anthropic pricing](https://www.anthropic.com/pricing) and [Claude for Work](https://www.anthropic.com/enterprise) for the plan that matches your team. See our Claude pricing UK guide.
Gemini (Google) spans consumer subscriptions, Google Workspace-related business offerings and developer/API usage. These are different products and should be compared separately. Check [Google AI plans](https://one.google.com/about/google-ai-plans/) and [Gemini for Google Workspace](https://workspace.google.com/solutions/ai/). See our Gemini pricing UK guide.
Perplexity focuses on answer-led research and search. Compare individual Pro access with any enterprise offering and API arrangements; check [Perplexity's official plans](https://www.perplexity.ai/pro) and current business terms before quoting a price. See our Perplexity pricing UK guide.
Grok is associated with xAI and X subscriptions. Eligibility and features may depend on the X plan and region; verify the current options at [X Premium](https://help.x.com/en/using-x/x-premium) and [xAI](https://x.ai/). Do not reuse historic SuperGrok or X prices without checking the live offer. See our Grok pricing UK guide.

Get partner pricingOfficeMaker is not a sixth chatbot. It is AI Build's document automation platform for repeatable Word, Excel, PowerPoint and PDF workflows. An assistant helps interpret, research or draft; OfficeMaker can turn structured inputs into controlled document outputs with templates, validation and approval. See [OfficeMaker](https://www.ai-build.ltd/products/officemaker). Compare the cost of an issued document or completed workflow, not only a monthly assistant licence.
A fair buying checklist
- Record the official price, currency, billing period, tax treatment and date checked.
- Separate consumer, team, enterprise and API products in the comparison.
- Check seat minimums, usage limits, model access and whether features require add-ons.
- Confirm data terms, retention, admin controls, SSO and permissions against your needs.
- Estimate total cost per useful outcome: licence + API + integration + human review + rework.
- Pilot with the same representative tasks and a clear quality, speed and governance scorecard.
Recommended next step
Start with the business job, not the brand. For general staff productivity, compare managed assistant workspaces. For research, test source quality and citation behaviour. For document-heavy operations, test the complete path from prompt or source data to an approved, archived file. For cross-system work, evaluate an assistant connected to approved tools through MCP.
