What does HammerAI do?
HammerAI is an AI character chat and roleplay platform where you start conversations by choosing from a wide range of characters across genres like Anime, Manga, Furry, and Original characters.
Chat right in your browser, or use the desktop app for a better experience. HammerAI supports multiple workflows, including roleplay chat, story writing, and image generation. You can also build lorebooks + personas, and tailor the vibe with settings like language and theme.
For privacy, HammerAI offers two ways to run: cloud-hosted models and local mode. Cloud-hosted messages are processed on secure servers, while local mode can run the LLM on your machine for total privacy, with messages not saved anywhere but your computer by default.
HammerAI is designed for anyone who wants character-driven, conversation-first roleplay—whether you prefer human characters, non-human archetypes (robots, monsters, elves, aliens, and more), multiple/fictitious characters, or non-English models. There are also category filters such as gender presentation and genres (like RPG, Sci‑Fi, Horror, TV Show, and Cartoon). HammerAI is 100% free to chat.
Is HammerAI free to use?
Yes. HammerAI is 100% free to chat, with both local-model and cloud-hosted options available.
Can I use HammerAI in my browser without installing anything?
Yes. You can chat directly in your browser. The desktop app is available if you want the best experience.
How does privacy work with cloud vs local mode?
Cloud-hosted messages are processed on secure servers. For total privacy, you can run the LLM locally on your machine so messages aren’t saved anywhere but your computer by default.
What else can I do besides character chat?
You can write stories and generate images, and you can build lorebooks + personas in addition to roleplay conversations.
Do the characters include non-human and fictional types?
Yes. You can find non-human options (like robots, monsters, elves, and aliens), plus multiple and fictional characters, using the available filters.
Can I use HammerAI in languages other than English?
Yes. You can change the language setting to use non-English models.
