Puti AI is a lightweight, privacy-focused desktop application that brings the power of ChatGPT and other large language models directly to your Mac or Windows device. Designed for speed, simplicity, and user privacy, Puti functions as a personal AI assistant that runs locally, enabling users to access generative AI without relying on a web browser or storing data in the cloud.
The app offers multi-model support, full keyboard accessibility, and instant search across your chat history — all while keeping your data private. Unlike browser-based AI tools, Puti operates as a native app, providing a smooth and distraction-free experience with advanced features for power users and professionals.
Whether you’re a developer, writer, researcher, or just someone who wants to chat with AI without compromising on speed or privacy, Puti AI offers a compelling alternative to traditional AI tools.
Features
Puti AI is packed with features that make it both powerful and user-friendly. One of its core strengths is privacy. All your chats are stored locally on your device, and the app does not transmit or track your conversations. This is ideal for users who value data control or work in sensitive environments.
The app supports multiple AI models, including GPT-3.5, GPT-4, Claude, and Gemini, depending on your API keys. Users can switch between models or configure different ones for different chats. This flexibility allows users to leverage the strengths of each model as needed.
Puti offers fast startup and instant chat response times, thanks to its native architecture. The interface is minimalistic but powerful, offering markdown support, local search across conversations, and even keyboard shortcuts for power users.
The tool also includes prompt templates, multi-chat management, and the ability to work offline with local caching (when using models that allow for it). Automatic updates ensure that users always have access to the latest features and improvements.
How It Works
Puti AI functions as a native desktop app. After downloading and installing the app on Mac or Windows, users simply input their own API keys from OpenAI, Anthropic (Claude), or Google (Gemini) to get started.
Once configured, users can create new chats and select the AI model they’d like to use. The chat interface is clean and responsive, supporting markdown for better formatting and display. Since all history is stored locally, users can search past conversations instantly without needing an internet connection or a login.
Because Puti uses your own API keys, it does not host or transmit your data. You pay only for what you use based on the pricing model of your chosen AI provider, without any markup or middleman.
Keyboard shortcuts make it easy to navigate and trigger actions, and the app supports multiple simultaneous chats, each with their own model or context.
Use Cases
Puti AI is designed for individual users who want fast and private access to generative AI tools. Writers and content creators can use it to brainstorm ideas, draft content, or edit documents using GPT or Claude.
Software developers can use Puti for code generation, debugging assistance, or quick access to technical documentation. Researchers and analysts can ask complex questions, summarize reports, or explore new ideas without leaving the desktop environment.
For business professionals, Puti provides a fast, secure way to draft emails, summarize meetings, or translate text without worrying about data security. Because everything runs locally and is API-key driven, it’s also ideal for teams working in compliance-sensitive fields.
Pricing
Puti AI follows a freemium model. The app itself is free to download and use with basic functionality. However, since the app connects to AI models through your personal API keys (e.g., OpenAI, Anthropic), you will be billed by the respective provider based on your usage.
There is no markup or added cost by Puti — you pay only what your provider charges.
A Pro version is available for users who want enhanced functionality, including additional settings, advanced prompt templates, and priority support.

Strengths
Puti AI is remarkably fast, lightweight, and privacy-conscious. By storing all data locally and avoiding cloud sync, it ensures full user control over personal and sensitive information. This makes it ideal for professionals or teams working in environments where privacy is a non-negotiable requirement.
The support for multiple models and API keys gives users flexibility to choose the best AI for their needs. The app’s keyboard-first design and minimal UI also appeal to productivity-focused users.
Because Puti is a native application, it consumes fewer system resources than browser-based tools and offers better integration with your desktop workflow. Frequent updates, local caching, and markdown support round out its appeal.
Drawbacks
Puti is designed for users who already have or are willing to obtain API keys from providers like OpenAI or Anthropic. Beginners who expect a ready-to-go chatbot out of the box may find the setup process a bit technical.
There’s currently no mobile version, and since it depends on external APIs, usage costs will vary depending on how often and how heavily you use it. Also, while the interface is clean, it doesn’t offer some of the built-in app ecosystem features found in heavier platforms like Notion AI or ChatGPT Pro.
Another limitation is that offline usage is restricted to cached content or open windows — models still require a live internet connection unless you run a local LLM separately.
Comparison with Other Tools
Puti AI offers a middle ground between browser-based tools like ChatGPT.com and self-hosted solutions like LM Studio or GPT4All. Compared to ChatGPT, Puti offers better privacy, faster local performance, and multi-model support, but lacks an integrated model unless the user provides an API key.
Compared to tools like Raycast AI or MacGPT, Puti is more feature-rich in terms of multi-chat support, search, and prompt management. While tools like Poe offer similar multi-model access, they are browser-based and manage data on their servers, which Puti avoids entirely.
For users who want control, speed, and privacy — with the freedom to choose their models — Puti offers a compelling solution that’s more customizable and desktop-native than many of its competitors.
Customer Reviews and Testimonials
Puti has received strong early feedback from users on platforms like Product Hunt and GitHub. Many users appreciate the app’s fast performance and minimalistic interface.
Common praise includes its ease of use, clean design, and the fact that users can rely on it without needing to log in or give up control of their data. Developers and power users especially appreciate the keyboard shortcuts and markdown formatting features.
Some users have requested future support for mobile platforms and additional features like model comparison or plugin integrations, which may be on the roadmap.
Conclusion
Puti AI is a privacy-first, high-performance desktop app that delivers the power of generative AI directly to your Mac or Windows system. It offers everything you need to work with ChatGPT, Claude, or Gemini in a secure, fast, and customizable environment.
By giving users full control over API access and local data, Puti fills a growing demand for tools that respect user privacy while still offering cutting-edge AI features. Whether you’re working on code, content, research, or productivity tasks, Puti provides a reliable and private co-pilot for your daily workflows.
