HammerAI review: the private one, with very loud laptop fans

That label is earned: I ran it locally on my own machine, so nothing I typed left the house.

My short version, before the details:

• I spent $0 over four months, mostly on local models
• The free plan gives 600 cloud messages a day, and local chat is free and unlimited
• Paid plans are Starter at $9, Advanced at $18 and Ultimate at $35, all monthly
• Paid chat never touches credits; images cost 10 and text-to-speech 5
• All purchases are final, with no refunds

My take: this is the app I'd hand to a friend who cares about data and doesn't mind a slightly technical setup. The price of all that freedom is complexity, from cloud or local models to credits and lorebooks. If you want a simpler character app to set against it, my CrushOn AI review is a useful point of contrast.

The second door is the desktop app. In May 2026 I installed it and ran the models locally, and the FAQ calls local chat "100% free", with no account needed. For me that was the whole appeal: my professional paranoia about data had nowhere to be, and honestly, it was restful.

The friction is real, though. Installation is one step more technical than normal-people apps, and I felt like both the customer and the IT department. Other reviewers report that on a mid-range laptop, local models answer slower than the cloud ones, and that the first model download is several gigabytes.

Images are the one thing free won't cover: with 0 credits, they need a plan or a pack. If you want pictures from the first minute instead, my Candy AI review shows a very different free start. Everything else sits in the HammerAI at a glance box below.

That fits the feature list. Group chats let you talk with up to ten characters at once, lorebooks are listed as "unlimited dynamic memory", and every plan includes automatic conversation memory through rolling summaries. For HammerAI roleplay with several voices in one scene, that set-up is rarer than it should be.

Memory is the one place the free plan feels tight. The free context is 8,192 tokens, and it grows to 16,384 on Starter, 32,768 on Advanced and 65,536 on Ultimate. Other reviewers report that characters forgot earlier details in long sessions on the free context, and that lorebooks helped.

For a single evening like mine, that is fine; for a campaign that runs for weeks, I'd plan to write the key facts into a lorebook.

On HammerAI chat quality, one outside write-up rates the top community characters as well written for what you pay, and notes that messages cost no credits. That matches how I'd sum it up: a writer's tool first, a companion app second.

There is also a text-to-speech library of 746 voices in 34 languages, but no live voice calls and no video. If you want those, this is the wrong shop. For how other apps handle memory and voice, my full list of app reviews covers each one on the same terms.

The character tools are the strong side. You can create characters on the web and on desktop, and the iOS listing mentions building AI characters of your own from a blank page, or importing them. Import matters to me: you are not stuck with whatever the hub happens to stock.

On comfort and inclusivity, I can only go by what's written. The records list no gender or appearance presets, so there's nothing to praise or criticise there. A free-form character creator does leave room to write whoever you want, and 746 voices give plenty of choice in how a character sounds.

The HammerAI image generator is the paid corner. Cloud images come from 22 image models at 10 credits each, and the free plan has 0 credits. So text is free and generous, pictures are not.

My take: for readers who mostly write and read, this is one of the calmest adult-content setups I cover, especially run locally where nothing leaves your machine. For readers who want pictures on every message, the credit meter will matter more. If an unfiltered chat is the main thing you're after, my uncensored AI app rankings compare the apps that allow it and on which plans.

The bigger difference is how the money works. Every paid HammerAI plan has unlimited cloud messages, and messages don't use credits. Credits pay only for images, at 10 each, and text-to-speech, at 5 each. Many rivals meter chat itself with coins or caps, and that's what makes a bill hard to predict.

Where HammerAI gives ground is media. There's no video on file and no live voice call, while several rivals bundle those in. You pay less and get a writing-first tool with an image generator attached, not a full companion package.

For heavy text roleplay on a budget, I think it's hard to beat. For a companion you call and hear, it's the wrong fit.

Starter fixes the free plan's two pain points: context doubles to 16,384 tokens and messages become unlimited. It also brings 1,500 credits, which is enough for 150 images or 300 text-to-speech clips, plus group chats and lorebooks.

Advanced at $18 and Ultimate at $35 mostly buy more context, more cloud models and more credits. Worth it only for heavy image users or very long stories.

Two details matter. Plan credits expire each billing period, while pack credits never expire, so a 600-credit pack at $4.99 can beat a bigger plan for irregular image use. And the plan cards show 1,500, 3,500 and 9,000 credits, while the FAQ says 2,000, 5,000 and 12,000. I'd plan on the lower figures. The table right after this lists every tier.

Before paying for anything, keep these points in mind:

• Paid plans are billed through Gank, a third-party payment service
• All purchases are final, with no refunds once complete
• Subscriptions bought inside the mobile app are managed in your device's settings
• Plan credits expire each billing period; pack credits do not

The refund rule is the part that bothers me. With no refunds at all, the smart move is to stay free until you're sure, and with 600 cloud messages a day plus local chat, you have room to decide.

If you'd rather have pictures, video and voice calls under one subscription, OurDream AI takes the opposite approach, with coins and a higher monthly price. My OurDream AI review shows how that compares, and some readers will prefer it.

If you subscribed through the mobile app, the FAQ sends you to your device's Settings, then Subscriptions, instead. So remember where you bought the plan, because web and app subscriptions live in different places.

Renewal is described loosely. It's a monthly subscription through Gank, and the FAQ says credits are topped up again when each new billing period begins, but there's no explicit auto-renewal sentence on file. I'd treat it as renewing every month until you cancel.

Refunds are the hard edge. The wording is blunt: every purchase is final, and since GankNow has no refund option, nothing comes back once you've bought. As far as the wording goes, that covers credit packs too. My advice is to buy a single month or the smallest pack first, never a big pack on impulse.

Payment runs through Gank by credit card and other methods, and mobile subscriptions go through the app store. The name on a card statement is not on file, which matters if you want discreet billing. Since the charge comes through a third party, I wouldn't assume it shows the app's own name. For how I weigh refund rules and billing clarity against price, see how I check the apps.

There's a fair caveat. Third-party model providers may retain data, so when you chat with cloud models your words pass through outside providers, and HammerAI's promise covers HammerAI, not them. That's the beauty of staying local. Running the models on my own machine meant nothing I said left the house, which is about as discreet as this category gets.

Deletion is clear too. Deleting your account erases all data related to it from HammerAI's servers, including cloud characters and stories, and it's irreversible. I'd copy anything you want to keep first.

Access is by self-declaration: users confirm they meet the minimum age before using the service, and no ID check is described. Payments run through Gank rather than directly, so the strict refund rule comes from that side.

On healthy use, one line from me: treat it like a game night, not a nightly habit. If you're still deciding what kind of character app suits you, my guide to the best AI chat character apps sorts the main options.

The plan I'd buy, if any, is Starter at $9 a month, for unlimited cloud chat and double the free context. What bothers me most is the no-refund rule, which turns every purchase into a final decision. Skip it if you want everything to just work out of the box.

• Live voice calls: Nomi AI includes them on its Standard plan, and Candy AI and OurDream AI list them too
• Video: OurDream AI and Candy AI both list video generation on paid plans
• Long-term memory without setup: one outside review credits Nomi AI with proactive long-term memory
• A simpler companion app: Candy AI centres on custom companions with pictures and voice

The trade-off is that almost all of these meter something HammerAI doesn't. Without a subscription, OurDream AI takes 1 Dreamcoin for every message, GirlfriendGPT Premium caps messages at 5,000 a month, and Nomi AI's free plan stops at 50 messages a day. None of them matches 600 free messages a day, let alone unlimited local chat.

So before you switch, ask whether the missing feature is worth giving up that allowance. For readers who mostly write stories, I doubt it. For readers who want a companion to call and hear, it clearly is.

If you'd like a big character hub instead, my SpicyChat review looks at another popular option. My own plan: keep HammerAI as the free base and add a second app only for the one thing it lacks.

If memory slips in long stories, try Starter for a month, since it doubles the context. Buy credit packs small, because purchases are final. Refunds, privacy and the local setup are all in the answers below.
