Best AI Search Apps on Mobile, Ranked

Leo, the AI assistant built into this browser, is free to use without an account, but the free tier has a usage cap that Brave describes only as depending on traffic. The app also blocks ads and trackers by default, includes its own search engine and shows its own opt-out ads. Leo Premium costs $14.99 a month, and the mobile builds run no browser extensions.
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.
Leo needs no account or sign-up on the free tier, and Brave publishes no daily prompt count; access is described as depending on traffic and usage. The free model list on Android 1.86 and later covers GPT OSS 20B, Llama 4 Scout, Llama 4 Maverick and Qwen 3 VL 30B. Leo Premium adds Claude Sonnet and Opus 4.6, DeepSeek v3.1, GPT OSS 120B, Mistral Large and Qwen 3 Coder 480B, plus higher limits and early access to new features. Brave lists it at $14.99 a month or $149.99 a year with a 7-day free trial, and the App Store shows the same amounts. TechRadar's July 2026 review hit rate-limit warnings during one long research session on the free tier. Prices are regional and can change.
On mobile, Leo opens from the Brave menu and reads the page you are on: summaries, translation, and questions about PDFs, Google Docs and Google Sheets. The model picker defaults to Automatic, which routes images to vision-capable models, always shows which model answered and lets you regenerate with another one. Bring your own model connects Leo to a local or remote model or a third-party API; on iPhone it appears in the version 1.91 release notes together with tool calling. Brave's own FAQ admits that Leo hallucinates, and a couple of Google Play reviewers in September and October 2026 call it slow, with one saying it dodges sensitive questions.
A chat sends your prompt and conversation context. A page summary sends the page content, including any text you highlighted. Tab management sends the titles and URLs of open tabs, though not Private or Tor tabs. A thumbs-up or thumbs-down on an answer sends the full conversation with the rating, model and version. Brave says it collects no identifiers such as an IP address, keeps no prompts or responses on its servers, deletes cached large prompts within minutes and does not train on chats. History stays on the device, is never saved in a Private window and can be switched off. Premium uses unlinkable tokens, so a purchase cannot be tied to usage.
The browser is free, but Brave Ads appear by default on the new-tab page and in Brave Search, and the browser ads can be toggled off. Search ads are switched off through Aggressive blocking in Shields or Search Premium at $3 a month. Brave Rewards pays in Basic Attention Token on Android, while on iPhone the FAQ says you cannot connect a payout account or earn BAT. Firewall + VPN costs $9.99 a month or $99.99 a year. Brave Origin, a one-time $59.99, is a stripped-down build with no AI and no crypto that covers all your devices. Prices are regional and can change.

The 8.0 rewards a free browser that pairs default ad and tracker blocking with a no-account AI assistant and a detailed privacy policy, held back by a Leo cap Brave leaves unnumbered and by Brave Ads that start switched on. Take it if you want blocking, search and an AI assistant in one free app. Skip it if you need extensions on a phone, expect unlimited free AI, or want to earn BAT on an iPhone.

Only on your device. Brave says Leo keeps history locally, never saves chats from Private windows and does not store prompts or responses on its servers; cached large prompts are deleted within minutes. You can switch history off or delete single conversations in Leo's settings. Subscriptions bought on iPhone renew automatically unless cancelled at least 24 hours before the period ends.
Brave and Google Chrome both run on the Chromium engine on Android and on Apple's WebKit on iPhone, according to Brave's own comparison page. Brave blocks ads and trackers by default and bundles Leo, which works only inside Brave. Firefox has run open extensions on Android since December 2023, which Brave's mobile builds do not match.
