Name	Hammer AI
Overview	Hammer AI combines character chat with creative writing tools, offering free local models and free or paid cloud options. Engage in deep conversations with a massive library of pre-existing characters from every corner of pop culture, or bring your own unique personalities to life with powerful creation tools. Its desktop app can run supported models locally after installation and model download; cloud inference, online advertising and optional sync have different data-processing implications. Use it for collaborative fiction, character art and entertainment, subject to the provider’s adult-access and content rules.
Key features & benefits	Extensive Character Library: Chat with thousands of diverse AI characters from anime, games, and more. Benefit: Never run out of new personalities and stories to explore. Local and Cloud Options: Desktop local inference processes chats on your device and can work offline after setup. Cloud chats are sent to external AI providers, which may retain or train on requests under their own policies. HammerAI’s privacy policy also describes browser-based sharing of recent chat and character context with Elo for free-tier ads. Paid plans remove that ad sharing, not cloud processing; this is distinct from offline local inference. Advanced Creation Suite: Go beyond chat to create your own characters, write intricate stories, build lorebooks, and generate images. Benefit: A single, powerful platform for all your creative AI-driven projects. Free Access and Paid Extras: Local chat remains free, while cloud access, image generation and text-to-speech have plan-specific limits or credits. Benefit: Try the free options before deciding whether paid features meet your needs. Highly Customizable Experience: Use detailed tags and filters to find the exact type of AI character or companion you’re looking for. Benefit: Quickly connect with AI personalities that match your interests and mood.
Use cases and applications	Immersive Roleplaying: Engage in dynamic roleplaying scenarios with AI that can act as a partner, guide, or adversary. Creative Writing & Brainstorming: Overcome writer’s block by co-writing stories or brainstorming ideas with an AI partner. Companionship & Entertainment: Chat with friendly, funny, or interesting AI characters for casual conversation and fun. World-Building: Develop detailed fictional worlds by creating lorebooks and a cast of characters to inhabit them. Art & Character Generation: Create visual representations of your original characters or scenes from your stories.
Who uses?	Creative Writers & Storytellers Roleplayers & Gamers Fans of Anime, Manga, and Pop Culture AI Enthusiasts & Hobbyists Adults seeking a choice between local-model and cloud character chat, subject to the provider’s age and content rules.
Pricing	Free local chat and limited free cloud access. The official website lists Starter at $9/month, Advanced at $18/month and Ultimate at $35/month. Paid tiers include cloud features and monthly credits for image generation and text-to-speech; chat does not consume those credits. Subscription credits expire at the end of the billing period, while separately purchased credit packs do not expire. Some official pages disagree on free cloud allowances and paid model counts, so confirm the current limits before subscribing. App-store prices can differ from website prices.

App available?	Available on the web, with desktop apps for Windows, macOS and Linux and official iOS/iPadOS and Android apps. The current FAQ and app release notes require an account for web/mobile cloud chat; desktop local use does not require one. Device-stored history is not the same as on-device model inference.

Before you start: Choose local or cloud processing, then try a non-sensitive fictional prompt and review the response before sharing it. HammerAI’s terms limit service use to adults aged at least 18 (or a higher applicable local threshold), for personal, non-commercial use; generated characters are entertainment, not professional advice.
