Licensing and platform notes

Facts to verify on hammerai.com before you depend on a workflow.
Free tier limits
Local chat is free forever; free cloud accounts get a limited selection of cloud LLMs and message limits per day.
Cloud privacy
Cloud models process messages on HammerAI servers without storing them for training—review the current privacy policy for details.
Local hardware
Local models require a capable desktop GPU or CPU; the app packages Ollama and auto-configures supported GPUs.
Subscription pricing
Paid plans start on paid monthly plans; monthly credits refresh each billing period and cover image and TTS generation.
Account optional
You can use HammerAI without logging in for local chat; an account enables cloud models, sync, and purchases.
Responsible use
Character chat may include adult or fictional content—use responsibly and per the platform’s terms and local law.
