Best AI Search Apps on Mobile, Ranked
An AI search app should do one thing a chatbot does not: show where the answer came from. Of the five we rank, only one is built around that from the
Microsoft Copilot is free to install and chat with, though free use runs on available capacity and accounts without a Microsoft 365 subscription may see ads. Beyond chat it offers voice, file uploads, camera questions for subscribers and Cowork, an agent that drafts email and builds Office files but is still in preview for personal accounts. Editing Word, Excel and PowerPoint files has moved to Microsoft's separate Office apps.
Specs come from the official store listings and were last checked on 2026-10-06. Developers change pricing and requirements — check the store page before installing.
Microsoft calls the free version limited and dependent on available capacity: chat, image creation and file uploads work until a limit is hit, then the app offers an upgrade or asks you to return later. The paid route is a Microsoft 365 plan, not a Copilot-only subscription. Personal is $9.99 a month with 1 TB of storage, Family is $12.99 and Premium is $19.99, each with a one-month trial; prices are regional, so check the offer in the app. On Personal and Family, voice, camera vision and image generation stay at standard usage, and a six-person Family plan gives its AI benefits to the owner alone.
Cowork is what separates the app from a plain chatbot. You describe a job, and it builds Word, Excel, PowerPoint or PDF files, drafts and sends email, manages your calendar and OneDrive files, or reruns a prompt on a schedule. The store screenshots show a progress list (searching email, reviewing Teams chats, creating an email draft) ending in a Send Email sheet with Cancel and Send buttons, so sensitive actions wait for approval. On personal accounts Cowork is labeled Preview and needs an eligible Microsoft 365 subscription. It cannot reach files on the phone or delete OneDrive files, and Microsoft warns that vague instructions get misread.
Microsoft's support page says editing Word, Excel and PowerPoint files inside the mobile app is discontinued. For subscribers, opening a file gives a preview with Copilot Chat for questions; editing sends you to the matching Office app, and the full file list sends you to OneDrive, while the Search tab keeps only recent files. New documents start in Chat: describe the file, and Copilot returns a download link that opens in the Office app. Another Microsoft update page lists Podcasts, Deep Research and Group chat as retiring features. Several Google Play reviewers say local files no longer open directly.
Without a Microsoft 365 subscription, Microsoft says users might see advertising in the app. Generic ads follow the current conversation, while personalized ones can draw on chat history and saved memories; the Allow ads personalization switch under Settings, then Personalization, turns that off, and accounts under 18 never get personalized ads. Toggles on the same screen cover Saved memories, web search and shared experiences with Bing, Edge and MSN. US accounts can also import Edge cookies, history, passwords and autofill data. On iPhone, the privacy label lists location, contacts and user content as data linked to you. Google Play lists camera, microphone and precise location permissions.
We don't host any files. These buttons open the official Google Play and App Store listings.
The 7.2 rests on a wide toolkit (voice, camera questions, file Q&A, a model menu and Cowork) held back by capacity-based free use, plan-gated agents and ads without a subscription. Take it if your files already live in Microsoft 365 and you want one assistant across Outlook, Teams and Office. Skip it if you need to edit documents on the phone, want a free tier without ads, or expect Premium-level agents on a $9.99 plan.

Yes, the app is free to download, and chat, image creation and file uploads cost nothing within limits that depend on available capacity. At a limit, the app offers an upgrade or asks you to return later. Accounts without a Microsoft 365 subscription may also see ads, and signing in unlocks chat history and longer conversations.
Cowork carries out a described job: it creates Word, Excel, PowerPoint and PDF files, drafts and sends email, manages your calendar and OneDrive files, and runs prompts on a schedule. It asks approval before sensitive actions. On personal accounts it is in Preview and needs an eligible Microsoft 365 subscription, and it cannot see files stored on your phone.
The app is free to install; paid features come through Microsoft 365 plans: Personal $9.99 a month, Family $12.99, Premium $19.99 and Pro $99.99, with a one-month trial on the first three (US prices that vary by region). Premium adds the Researcher and Analyst agents and more voice, vision and image usage, so it pays off mainly if you keep hitting those limits.
You keep the free app and chat, but the paid extras stop. Vision needs a Personal, Family or Premium subscription, Cowork on personal accounts needs an eligible subscription, and the Researcher and Analyst agents are Premium and Pro features. Ads can appear without a subscription. Individual chats can be deleted from the Chats list.
It fits best when your work already lives in Microsoft 365, because it connects to Word, Excel, PowerPoint, Outlook and Teams and can run Cowork tasks across them. As a general chatbot, ChatGPT and Gemini are the closer comparison. Its model menu also lists Claude, Anthropic's assistant, though availability depends on your license.
