HammerAI Review: An In-Depth Overview

In an age when privacy is a growing concern, HammerAI emerges as a groundbreaking solution in the AI chat arena. Operating solely on a user's local machine, HammerAI offers an array of features that prioritize user privacy, simplicity, and accessibility.

Core Features

  • Localized Processing: Unlike cloud-based solutions, HammerAI operates entirely on your computer, ensuring the utmost privacy.
  • No Sign-In Required: HammerAI eliminates the need for user registration, further strengthening its commitment to user privacy.
  • Platform Versatility: Available as both a web-based chat and a desktop application, HammerAI aims for maximum accessibility.
  • Character Customization: Users can interact with a diverse set of characters or even create their own.
  • Content Control: HammerAI offers both censored and uncensored models, giving users the freedom to choose their experience.

Privacy Above All

HammerAI goes to great lengths to protect user privacy. All chat data is processed locally, meaning that no conversation leaves your computer. Chat logs are also not stored beyond the active session, eliminating any concerns about data retention. For those skeptical about these privacy claims, HammerAI provides a simple test: turn off your internet connection, and you'll find that the chat functionality remains intact.

Supported Devices

Currently, HammerAI Web supports browsers with WebGPU capabilities, such as Chrome, Edge, and Opera. The desktop version is presently compatible only with Apple Silicon (M1 / M2) MacOS machines, although versions for Intel MacOS and Windows are in the pipeline.

Character Management

When users create their own characters, they receive a unique secret key. This key allows them to edit their character in the future. While web users receive this key in a URL, desktop users have it saved on their local machine within the HammerAI application.

Monetization Strategy

While all features are free to use, HammerAI has a Patreon page for those who wish to support the project. The company pledges never to charge for features, collect, or sell user data.

Content Guidelines

HammerAI maintains a liberal stance on content but draws the line at illegal or highly sensitive material, such as child pornography, sexual violence, and heavy gore. Users are encouraged to report any such content.

Works great

I’m You’re GOD
I’ll give it three stars because it doesn’t work for iPhones

I Give it a three because I liked designs, but it’s not made for iPhones if you can have a version for iPhones, that would be awesome.
