HammerAI for iOS & Android
Free and unlimited AI character chat and roleplay, now on your phone.
Why HammerAI on Mobile?
Free to Start, Private by Default
The HammerAI mobile app is free to download and use, with no sign-in required to get started. Free accounts get unlimited chat on a selection of cloud LLMs, plus unlimited character creation, group chats, lorebooks, and personas. Paid plans (starting at $9/month) unlock more cloud models, larger context sizes, cloud image generation, and text-to-speech — but the core character chat experience is free forever. Your chats and characters are stored on your device by default, so they don't have to leave your phone.
All the Features You Love
The HammerAI mobile app brings the same features you know from the web and desktop apps — AI character chat, AI image generation, AI story writing, group chats with multiple characters, lorebooks, and personas — all designed to work great on a small screen with smooth, responsive interactions. Whether you want to roleplay with an AI companion, brainstorm story ideas, get coding help from an AI assistant, or just have a thoughtful conversation, the HammerAI mobile app makes it possible from anywhere.
Available on Every Device
HammerAI is available now on iPhone and iPad via the App Store, and on Android via Google Play — alongside the web and desktop apps. Sign in and your account, subscription, and cloud chats sync across every device, so you can start a conversation on your phone and pick it up later on your desktop. Prefer not to install anything? The HammerAI web app at hammerai.com also works great in any mobile browser.
