The best AI app depends on what you need it to do: ChatGPT is a strong all-purpose starting point, Claude suits writing and coding workflows, Gemini fits Google-connected work, Perplexity is useful for research with inspectable sources, and Microsoft Copilot is designed around Microsoft 365. These are practical picks, not a claim that one app is best at every task.
How to choose an AI app
Start with the job you need done, then consider how the app fits your existing services and files. If current facts matter, look for a way to inspect sources and verify important claims yourself. Also compare free-tier limits with paid features, and review permissions and privacy controls before connecting work accounts or uploading sensitive content. Features, models, limits, and availability can vary by plan, account, device, and country.

The five AI apps
1. ChatGPT: best all-purpose starting point
ChatGPT is a flexible choice for everyday questions, learning, web search, image generation, work deliverables, and coding workflows, according to OpenAI’s product overview. Its range makes it a sensible first app if you want one assistant for varied tasks. Not every capability is available on every plan, so check the features included with your account.
Recommended Free Tools
2. Claude: writing and coding workflows
Claude is a good fit to consider for writing, coding, reasoning, and working with long documents. Anthropic describes workflows across documents, spreadsheets, and multi-step tasks on its product overview. These are vendor-described capabilities, not evidence that Claude outperforms alternatives in every task.

3. Gemini: Google-connected work
Gemini makes sense if your work already relies on Google’s ecosystem. A 2026 comparison describes its free tier as generous, but what is included and how much you can use may depend on your country and account. Check the current terms that apply to you rather than assuming the same access everywhere.
4. Perplexity: research with references to inspect
Perplexity is worth considering when you want an AI-assisted search or research workflow and references you can follow up on. Its plan guide describes search and research features. Citations are useful starting points, not a guarantee that an answer is correct: open the linked sources and confirm important claims, dates, and context.

5. Microsoft Copilot: Microsoft 365 workflows
Copilot is the natural option to examine if your work happens in Microsoft 365. Microsoft says it is integrated with Word, Excel, PowerPoint, Outlook, and Teams, with access across desktop, mobile, and web on its Copilot product page. Microsoft describes the service as connecting with work content and familiar apps to help create finished work; that is the company’s product positioning, not an independent assessment. Some newer features may be preview-only, and work accounts can have different entitlements.
A focused option for study and source-based work
Gemini Notebook
Google’s Gemini Notebook is a specialized option for working from information you trust. Google describes features for turning files into slide decks, mind maps, and audio or video overviews. It is aimed at focused research and study workflows rather than replacing a general-purpose assistant.

What to check before you rely on one app
- Plan and limits: Free access does not necessarily include the same models, features, or usage allowance as a paid plan. Review the current details on the provider’s site.
- Region and account: An advertised feature may not be available to every country, account type, or device.
- Connected content: Before granting access to work files or uploading sensitive material, check the app’s permissions and the controls offered by your provider.
- Important facts: Treat generated answers as something to verify, especially for decisions that depend on accuracy or up-to-date information.
Comparison guides can help identify likely fits, but their rankings are editorial judgments rather than controlled benchmarks. No single app wins for every reader or workflow.
