HammerAI

HammerAI is a 100 % free, fully private AI character-chat platform that runs either in your browser or in the cloud. With unlimited messages, built-in image generation, and persistent lorebooks, writers, gamers, and creators craft vivid characters and stories without paywalls or data retention. Install once, create forever.

Unlimited Conversations Without Throttling

Most freemium rivals insert daily message caps or slow response queues. HammerAI imposes none. You can chat for hours, batch-generate hundreds of NPC backstories, or iterate on a 50-chapter fantasy epic without hitting an invisible wall.

Privacy by Design

Local mode keeps every byte on your machine. Cloud mode encrypts prompts in transit (TLS 1.3) and scrubs server logs after each session. No email, no phone number, no tracking pixels—GDPR and CCPA compliance baked in.

Multimodal Toolkit

Beyond text, a built-in Stable Diffusion XL pipeline produces 1024×1024 character portraits from the same prompt box. Lorebooks let you build persistent world bibles, while the storyboard mode auto-chains scenes and dialogue beats. All assets are downloadable as JSON or PNG, ready for import into Twine, Scrivener, or Foundry VTT.
