HammerAI is a character chat and roleplay app: you chat with community-made or self-made characters, write stories with an AI co-author, run group chats and build lorebooks and personas. What sets it apart is the choice of engine. The desktop app runs models on your own graphics card, free and offline; the web and phone apps run cloud models, free up to a daily cap or unlimited from $9 a month.

Everything below comes from pages anyone can check on 20 October 2026: hammerai.com's pricing page and the plan data in it, the FAQ, the desktop and mobile pages, the documentation, the release notes, the Terms of Service (last updated 29 May 2026), the Privacy Policy (16 October 2026), the Cookies Policy, the Content Guidelines, and the App Store and Google Play listings. It is not a hands-on test: there are no chat logs, image samples or speed claims, and nothing that sits behind the login wall.

What You Get

The pricing page opens with "HammerAI is built by one developer as a passion project". The app store listings name the publisher as Sunspot LLC; the Google Play developer address is in Albuquerque, New Mexico, USA.

• Platforms: web app, desktop app for Windows, macOS (Apple Silicon only) and Linux (Debian, Flatpak, RPM), an iOS app and an Android app (the Google Play listing com.hammerai.app was live on 20 October).
• Two engines: local models on your own machine (desktop only) or cloud models on HammerAI's servers (web, mobile, and desktop if you choose them).
• Characters: build your own characters, personas and lorebooks, or start from the public library: HammerAI's sitemaps listed 7,768 unique public character pages and 154 stories on 20 October 2026. The desktop app can also browse and download Chub AI character cards (release 1.0.59, 2 July 2026).
• Images and voice: 26 image models and 746 text-to-speech voices in 34 languages, paid with credits. No video generation and no calls on the official pages.
• Account: the FAQ says chatting on the web and mobile apps requires a free account, since every model there is a cloud model. The desktop app with local models needs no login.

Local Mode: Free, Offline, Hardware-Bound

The desktop page says the app is "Powered by Ollama and Llama.cpp", needs no configuration or login, works offline, and that HammerAI "supports 20+ LLM's" out of the box, with your own Ollama Modelfile as an option. The FAQ promises local AI chat "will always be free". Release notes from July 2026 add a HuggingFace model browser and local text-to-speech through Piper or Kokoro.

The cost is hardware, and HammerAI's own quantization guide is explicit about it. A model must load fully into RAM or VRAM, with a 10 to 50 percent buffer on top of its file size. It recommends q4_K_M or q5_K_M quantizations and gives these examples:

The guide's own advice is to install a small model first and move up or down depending on speed. Its Ollama documentation also explains that Ollama may split a model between CPU and GPU (its example: "48% CPU / 52% GPU") when it does not fit entirely in VRAM. In short, the free version is only as capable as the graphics card you already own.

Two more free-tier features on the pricing page: "Proxy to any LLM API", which lets you plug in your own API key for another provider, and a July release that added bring-your-own-key image providers (X.ai, OpenAI, Pollinations, StabilityAI, NanoGPT, TogetherAI, DeepInfra and FireworksAI). The model-parameters documentation covers temperature, Top-P, Top-K and repetition penalty, and the plan comparison table lists Min-P as well.

Cloud Mode: Models, Context & Features

Cloud mode is what the web and phone apps use. The pricing page ties three things to your tier: daily message limit, context window and number of cloud models. Which cloud models each tier gets today is not listed on the public pages.

• Context window: 8,192 tokens on Free, 16,384 on Starter, 32,768 on Advanced, 65,536 on Ultimate. Few competitors publish memory as a hard number.
• Automatic memory: rolling conversation summaries are a paid-plan feature (release 1.0.61, July 2026). Free users can fill in the memory field by hand, and get one pinned message against unlimited on paid plans.
• Group chats and lorebooks: the comparison table lists group chats with up to ten characters and lorebooks on every tier, Free included.
• Images and voice: 10 credits per image and 5 per voice clip. Free gets 0 credits.
• Free cap: 600 cloud messages a day, a limit added in release 1.0.66 (18 July 2026) because "a handful of accounts" were abusing the system.

Adult Content & Rules

The site footer promises "raw, uncensored conversations and deep roleplay with no filters and no limits." In local mode the model runs on your machine and HammerAI does not see the chat; the terms still say conversations must not contain prohibited content. Explicit roleplay in text is what HammerAI is built for. Images are more limited: photorealistic images of people are banned, and every main profile picture must be PG-13.

On the platform, the Content Guidelines (last updated 7 April 2026) list 17 prohibited categories. The ones most likely to matter in an NSFW app:

• Underage content: all characters must be 18+, with no loopholes. Childlike imagery, including "loli" and "shota" styles, is removed; canonically underage characters may only appear if explicitly aged up in both descriptions.
• Real people and celebrities: banned, including realistic depictions. Actors in a role are allowed if not photorealistic.
• Photorealistic images of people or animals: treated as real even if AI-generated, so not allowed.
• Mature characters: allowed, but the main profile picture must be PG-13, with no nudity.
• Also banned: gore, bestiality, sexual violence, non-fantasy necrophilia, blood incest, trafficking, extremism, self-harm.

The Compliance page (22 March 2026) says content involving minors, self-harm encouragement, graphic violence and hate speech "is actively filtered and blocked" and that age is confirmed by the user. Both store listings are rated 17+ / Mature 17+, and the App Store listing carries the advisory "Infrequent/Mild Sexual Content and Nudity". On the public pages we found no minor-coded tags (the tag list has "Student" and "Teacher", described as academic roleplay, but no teen, school-age or loli tags), and a sample of 200 public character pages from the sitemaps showed no minor-coded descriptions. The tag list does include "Celebrity", which sits awkwardly with the real-people rule.

Prices & Which Plan

We loaded the pricing page from France; it showed US dollars and no euro conversion. Prices seen on 20 October 2026, all monthly on the web:

Subscription credits refresh each billing period and do not roll over. Credits bought in packs never expire. Upgrades are charged the prorated difference; downgrades apply at the end of the period. There is no annual plan on the web.

In the app stores: the US App Store lists in-app purchases the web pricing page does not show: Starter Weekly $2.49, Starter Monthly $8.99, Starter Quarterly $23.99, Advanced Weekly $4.99, Advanced Monthly $17.99, Ultimate Weekly $9.99 and Ultimate Monthly $34.99, plus the Tiny, Small and Medium credit packs at web prices. The listing doesn't spell out what each includes; they presumably match the web tiers of the same name, but we could not confirm that. The Google Play listing gives only a range for in-app purchases, $1.99 to $329.99 per item. Weekly billing works out at about $10.79 a month for Starter and $43.29 for Ultimate, against $8.99 and $34.99 monthly.

Credits pay for images and voice. Every way to buy them, down to a cost per credit and per image (10 credits):

Which plan to pick:

• You have a capable GPU: start with the free desktop app and a small local model. You only need a plan for cloud images, voice or chatting from your phone.
• You chat in the browser or on your phone: Starter at $9 a month. For $0.99 less than the Medium credit pack (1,300 credits and nothing else) it gives 1,500 credits plus unlimited messages, double the free context and no ads. Pay monthly on the web (or $8.99 monthly in the App Store), not weekly.
• Long roleplays with lots of lore: Advanced at $18 doubles the context to 32,768 tokens; Ultimate at $35 doubles it again and has the lowest cost per credit.
• Only a handful of images, once: a small pack. Pack credits never expire, while subscription credits reset every month.

Before You Pay

Refunds, cancelling and who runs it

• Refunds: the pricing page says "GankNow does not support refunds, so all purchases are final." The Terms of Service (29 May 2026) never mention refunds.
• EU and EEA buyers: section 28 of the terms keeps "the right to withdraw from distance contracts within 14 days", the right to sue at home, and excludes the arbitration clause where it conflicts with EU consumer law.
• Cancelling: web subscriptions are managed from your Gank account ("cancel, pause, or modify"); App Store subscriptions from your device settings. Deleting your HammerAI account does not cancel an App Store subscription, the terms warn.
• Company: Sunspot LLC per the App Store and Google Play listings (Play lists an Albuquerque, New Mexico address and team@hammerai.com); the terms themselves only say "HammerAI". They are governed by Delaware law, with AAA consumer arbitration and a class-action waiver; you can opt out of arbitration by email within 30 days of accepting the terms.
• Payment: cards and "other payment methods through Gank" on the web; Apple or Google billing in the apps. Gank is the merchant of record.
• Age checks: self-declared. The terms and Compliance page rely on users confirming they are 18+; we saw no third-party age verification on the public pages.

Privacy: local mode vs the free web tier

• Local mode: the FAQ says conversations with local models "never leave your device", and suggests checking it by disconnecting from the internet. On paper this is the strongest privacy option in this category.
• Cloud chat: the FAQ says cloud messages are sent to HammerAI's servers "but are not stored or used for training". The privacy policy adds (section 13) that messages are sent to third-party AI providers, such as those reached through OpenRouter, which "may process and retain" them under their own policies, including for training.
• Ads on the free web tier: section 11 of the privacy policy, updated 16 October 2026, names Adsterra and Elo (elo.ad, formerly Growl). "To select ads relevant to your conversation", the browser sends recent chat content and character information to Elo through a HammerAI subdomain, on the free tier "regardless of your cookie settings". Paid plans remove these ads and stop it. The cookie policy lists Elo's persistent visitor cookie and ad-preference cookies for cemiocw.com and bongacams.com.
• Analytics: the policy names Google Analytics 4 and a self-hosted Umami. GA cookies (_ga) last up to two years and are only set after consent for visitors in the EU, EEA, UK and Switzerland. The site's public JavaScript matches: a GA4 loader gated on consent and the elo.hammerai.com ad endpoint. The page source also carries site-verification tags for two adult ad networks, JuicyAds and TrafficStars, which the policies do not name.
• Other processors: Sentry (crash reports), Cloudflare, Supabase and Vercel; payments through Gank.

The marketing and the documents don't fully agree: the homepage says "Private and personal" and the App Store description says "no ads, no tracking"; section 2.1 of the privacy policy reads "We do not collect any information about your conversations with characters", and section 10.1 of the terms says all conversations "exist only on the device", while sections 11 and 13 of the privacy policy describe chat content going to an ad provider and to third-party AI providers. The desktop page says local messages "are deleted each time you close it", while the FAQ says local chats "remain on your device". If privacy is the priority, use the desktop app with a local model, or pay to remove the ads on the web.

Small inconsistencies on the official pages

• Model counts: the plan cards list 2 / 4 / 8 / 16 cloud models; the comparison table on the same page says 2 / 4 / 6 / 10. The credit figures now match everywhere: 1,500 / 3,500 / 9,000.
• Free cloud model: the pricing page's structured data still names "Smart Lemon Cookie 7B", while release 0.0.247 (29 October 2025) says it was replaced on Free by Llama 3 8B Lunaris.
• "Unlimited" free chat: the mobile page still promises free accounts "unlimited chat on a selection of cloud LLMs"; the pricing page caps Free at 600 messages a day.
• Login: character category pages say "no login required", the mobile page says "no sign-in required to get started" and the App Store description says "No account required"; the FAQ says web and mobile chat requires a free account, and the iOS 1.2 release notes read "Require login to use the app to prevent abuse."
• Release notes: the public notes stop at 1.0.67 on 18 July 2026, while the iOS app shipped version 1.2 on 1 October and the Android app was updated on 6 October.

User feedback

Thin. We found no Trustpilot profile for hammerai.com on 20 October 2026. On the US App Store the iOS app averaged 3.2 stars from 17 ratings, and its only written review (1 star, August 2026) complains the phone app cannot use a model running on the user's PC. The Google Play listing showed 100+ downloads and no public rating yet. No source reaches the 50 reviews our scoring needs, so this sub-score is neutral.

One more thing to know: HammerAI sells advertising on its own site (banners on the Characters and Chat pages at $1,000 a month, text spots at $500, Stories page spots at $500 and $300, and a sponsored blog post at $1,000 a year, paid via PayPal).

Alternatives

Pick by what you want that HammerAI does not give you (scores under the same method):

Final Verdict — 7.0/10

Install the desktop app if your PC can run a model; otherwise the $9 Starter plan is a fair price for unlimited cloud roleplay.

Local mode is HammerAI's standout: a free desktop app that bundles Ollama, needs no account, runs offline, publishes its own hardware guide and lets you plug in your own API keys. On the cloud side the plans are clearly specified, with exact context windows per tier, and Starter at $9 a month is cheaper per credit than the small packs while adding unlimited messages and removing ads. Prices are public before sign-up, cancelling is self-serve, and we saw no countdowns or struck-through prices.

What holds the score back: no video or calls, no realistic images under its own rules, explicit content documented for text only, every purchase final, and too little user feedback to go on. Free web users should also know their recent chat is now used to pick ads.
