These seven free AI tools cover everyday questions, web research, design and image creation, and writing help. The evidence available supports seven examples—not a verified list of 20 or more—and not every app has confirmed feature parity on Android and iOS. Check the current store listing and plan details for your device and region before relying on a particular feature.
Choose an app by the job you want done
“Free” can mean a no-cost plan with usage limits, a free app with limited daily generations, or access to selected features at no charge. App availability is also separate from feature availability: a product may have a phone app while a particular AI feature is web-only, desktop-only, limited by account, or still rolling out.

For questions, drafting, and everyday help
ChatGPT
OpenAI describes its Free plan as suitable for everyday conversations, writing help, and learning. That makes it a broad starting point for asking questions, brainstorming, and drafting. Core free features have usage limits, and the cited official page does not establish a specific Android-versus-iOS feature matrix. Check the app listing and current plan information for your device before assuming a feature is available.

Microsoft Copilot
Microsoft says the free version is available on both iOS and Android. Its mobile support page describes chat, voice conversation, summaries, and drafting. Microsoft Support’s “Get started with the Microsoft Copilot mobile app,” last updated February 2026, says: “Microsoft Copilot uses the power of artificial intelligence (AI) to help you be more productive and creative through an advanced chat experience, all from your mobile device.” Microsoft cautions that feature availability may vary by region.

For web-based research and answers
Perplexity
Perplexity provides a Free (Standard) plan and compares its included capabilities with paid plans. It is a candidate for asking questions and research, but do not count on access to a particular advanced model or other paid-plan capability on Free. The cited plan information does not establish Android or iOS availability, so verify the current official listing for your phone.
For designs and generated images
Canva
Canva lists a no-cost Free plan, and its help information says Free users get limited monthly use of some AI tools. The allowance depends on the plan and tool; do not assume every Canva AI feature is included or that Canva AI 2.0 is fully available to Free users.

Adobe Express
Adobe’s Free plan includes basic tools, limited assets, and mobile-phone support. Keep that separate from the Adobe Express AI Assistant beta: Adobe says that particular assistant is desktop-only, is rolling out gradually, and may vary by account. A mobile Express app does not establish that the beta assistant works on a phone.
Recommended Free Tools
Adobe Firefly
Adobe says Firefly is free to download from the Apple App Store and Google Play, with limited free daily generations. Downloading the app does not mean unlimited free use; extra access is subscription-based, and generation availability and limits can change.

For writing suggestions and rewrites
Grammarly
Grammarly documents mobile solutions for Android and iOS, as well as generative assistance on Android, iPhone, and iPad. Those sources establish mobile support and AI functionality, but not which specific capabilities or allowances are included in the free tier. Check the current plan information before choosing it for a particular writing task.
Check these details before you depend on a feature
- Free plan versus free download: Confirm whether the feature you need is included without payment, rather than assuming that an app-store download includes unlimited use.
- Usage allowance: Look for usage limits and whether they reset daily or monthly. The official information cited here describes limits for ChatGPT’s core Free features, some Canva AI tools, and Adobe Firefly generations, but does not establish comparable quotas across all seven tools.
- Phone support versus feature support: Confirm that the specific AI function works in the app, not only on a desktop or web version.
- Eligibility: Region, account, language, operating-system version, and rollout status can affect access. Check the official app listing and product help page for your circumstances.
- Current terms: Plans, limits, and feature availability can change. Recheck the provider’s official information when making a decision.
Why this is a seven-app list, not “20+”
The current official information cited here supports seven named examples, with different levels of evidence for mobile availability and free features. It does not substantiate 20 distinct apps with current free-plan and Android/iOS evidence. Calling this a verified “20+” list would overstate what is established. The options above are a more useful starting point: choose the task first, then confirm the app and feature are available to you.
