AI tools now overlap heavily: most can write, summarise, analyse files, search the web and help with coding. The useful question is no longer simply “which one is best?”, but which tool fits the way you actually work – and what you need to verify before relying on it.

Scope: This guide compares mainstream consumer and workplace AI tools for writing, research, coding and office productivity. Features, usage limits and prices change quickly, so always check the provider’s current plan page before paying.

At a glance: where each tool is strongest

Tool	Where it stands out	Important caveat
ChatGPT	Broad general-purpose work: writing, reasoning, files, data analysis, coding, images, research and connected tools	Plan limits and model access vary significantly between Free, Go, Plus and Pro
Claude	Long-form writing, document work, coding and structured analysis	Research and higher-usage features depend on plan
Gemini	Google ecosystem, Gmail/Docs/Sheets integration, large-context research and multimodal work	Some advanced features are plan- or region-dependent
Perplexity	Web research, source-heavy answers and fast comparison of information from multiple sites	Citations still need checking; a cited source does not guarantee the conclusion is correct
Microsoft Copilot	Word, Excel, PowerPoint, Outlook and Microsoft 365 workflows	Consumer and business Copilot products have different features and pricing
GitHub Copilot	Software development inside IDEs, GitHub and coding workflows	It is specialist developer tooling rather than a general office assistant

1. ChatGPT

General-purpose AI

ChatGPT

ChatGPT is no longer accurately described as “GPT-4o plus DALL-E 3”. OpenAI’s current consumer plans use newer GPT model families and the product now bundles search, file uploads, data analysis, image generation, deep research and other tools inside the same service.

Useful for: mixed workflows where you may move between writing, spreadsheets, PDFs, coding, research and images in the same session.

Plan note: Free, Go, Plus and Pro have different usage limits and access to advanced reasoning, research and productivity features. Because OpenAI changes model names and entitlements frequently, this article does not treat one model name as the permanent definition of ChatGPT.

2. Claude

Writing and document work

Claude

Claude remains strong for writing, editing, coding and long-document work, but an important old claim is no longer true: Claude Free does have web search. Anthropic’s current Free plan also includes memory, web search and file creation/code execution, while paid plans add more usage and features such as Research.

Useful for: drafting and revising long documents, structured reasoning, document analysis and coding tasks.

Pricing note: Anthropic currently lists Claude Pro at US$20/month when billed monthly, or US$17/month equivalent on an annual subscription. UK billing can include tax and currency conversion.

3. Gemini

Google ecosystem

Gemini

Gemini is especially relevant if your work already lives in Gmail, Google Drive, Docs or Sheets. Google’s current UK AI plans include Google AI Plus, Pro and Ultra, with higher tiers increasing access to advanced Gemini models, Deep Research and other AI features.

Useful for: work centred on Google apps, large document sets, multimodal tasks and research inside the wider Google ecosystem.

Check before paying: some features are country-specific, and Google changes plan names, storage bundles and AI usage limits regularly.

4. Perplexity

Web research

Perplexity

Perplexity is built around search and cited answers. The free plan supports basic search, while Pro adds deeper research, more file analysis, advanced model access and higher limits. Perplexity currently lists Pro at US$20/month.

Useful for: finding sources quickly, comparing multiple webpages and beginning a research task with citations already attached.

Important: citations improve traceability, not truthfulness. You still need to open the source, check whether it actually supports the claim, and prefer primary sources for finance, law, tax, health or technical specifications.

5. Microsoft Copilot

Microsoft 365

Microsoft Copilot

The old statement that Microsoft 365 Copilot simply costs £25 per user per month is now outdated. Microsoft’s current UK offering is split across consumer Microsoft 365 plans and business Copilot products. Microsoft 365 Personal currently includes Copilot features, while Microsoft 365 Copilot Business is sold separately for workplace use and can also be bundled with Business plans.

Useful for: people whose day already revolves around Word, Excel, PowerPoint and Outlook.

Check carefully: Microsoft publishes different prices for annual and monthly billing, with or without Teams, and promotional prices can appear temporarily.

6. GitHub Copilot

Developer AI

GitHub Copilot

GitHub Copilot has changed substantially from the old “£9/month, no free tier” description. GitHub now offers a Free plan as well as paid Pro, Pro+, Max, Business and Enterprise tiers. The current individual Pro price is US$10/month.

Useful for: developers who want code completion, chat, agents and code review inside development environments and GitHub workflows.

For a non-developer who mainly writes documents or analyses spreadsheets, a general-purpose assistant is usually a more relevant comparison.

Which tool for which task?

Task	Tools worth testing	What to compare
Writing and editing	Claude, ChatGPT, Gemini	Tone control, document length, revision quality and file handling
Research with sources	Perplexity, ChatGPT, Gemini, Claude	Source quality, whether claims are actually supported, and research depth
Spreadsheets and data	ChatGPT, Microsoft Copilot, Gemini	File-size limits, formula accuracy, charts and integration with your existing suite
Coding	GitHub Copilot, ChatGPT, Claude, Gemini	IDE integration, repository context, agent tools and code-review workflow
Microsoft 365 work	Microsoft Copilot, ChatGPT, Claude	Whether the AI can securely work with your actual organisational files and email
Google Workspace work	Gemini, ChatGPT, Claude	Gmail/Drive/Docs/Sheets integration and admin controls
Image generation	ChatGPT, Gemini and specialist image tools	Editing accuracy, text rendering, style control, licensing and usage limits

Pricing: use this as a snapshot, not a promise

AI pricing is unusually volatile. As at 12 September 2026, useful reference points include Claude Pro at US$20/month when billed monthly, Perplexity Pro at US$20/month and GitHub Copilot Pro at US$10/month. Microsoft lists Microsoft 365 Personal at £8.49/month in the UK and Microsoft 365 Copilot Business from lower per-user prices on annual billing, but business pricing varies by bundle, Teams inclusion and promotions.

For ChatGPT and Gemini, compare the current local checkout page rather than relying on an old pound figure. Both companies now offer several consumer tiers, and the value difference is increasingly about usage limits and tool access rather than a single “premium model”.

Privacy and work data: the part people skip

Do not paste confidential employer, customer, medical, legal or commercially sensitive information into a consumer AI account just because the tool is convenient.

Consumer and business AI products can have different data-use rules. OpenAI’s consumer plans provide an opt-out from use of content for model training. Anthropic also gives consumer users a choice over whether their data is used for model improvement. Commercial or enterprise plans generally offer stronger contractual controls, but the exact protections vary by provider and plan.

For workplace use, check your employer’s approved-tools policy, the provider’s current data-processing terms, retention settings, admin controls and whether your organisation has a business agreement in place.

How to choose without overpaying

Start with the task. List the two or three things you actually want AI to do each week.
Test the free tier first. Use the same real-world task in two or three tools.
Check the workflow, not just answer quality. Uploads, integrations, citations, export options and context matter as much as prose quality.
Verify high-stakes facts independently. Search access and citations reduce friction; they do not eliminate hallucinations or source errors.
Only pay when the limit is the problem. Upgrade because you need more usage, a specific feature or better integration – not because a paid badge sounds more capable.

So which one should a UK worker try first?

There is no defensible single “best AI tool” for every worker. A sensible starting point is to test the free versions of two tools against the same real task. If you use Microsoft 365 all day, Copilot deserves a look. If your work is centred on Google apps, Gemini has a natural integration advantage. If you need source-heavy web research, Perplexity is useful. For broader mixed work, ChatGPT and Claude are both strong general-purpose options.

The deciding factor should be the workflow you need, the quality you get on your own tasks, the privacy rules that apply to your work and whether a paid tier actually saves enough time to justify the cost.
