Dhito: The Privacy-First Semantic File Search for macOS

Research Context and Background

Dhito is a privacy-focused application designed for macOS users who want to find and interact with their local files using natural language. It uses artificial intelligence that runs entirely on the user's device to understand the content of documents, images, videos, and audio files. Unlike traditional search tools that rely on keywords, Dhito understands the context within files, allowing users to search for specific details like a photo from a trip or a document from a specific year. The app operates with a zero-cloud architecture, meaning no data leaves the user's computer, no accounts are required, and no tracking occurs. All processing happens locally, even when the computer is offline.

Benefits

Dhito offers several key advantages for users who manage large collections of digital files. The most significant benefit is its ability to understand natural language. Users can describe what they are looking for in plain English rather than guessing exact file names or keywords. For example, a user can search for "the receipt from the blue coffee shop" and find the correct file instantly. The app also allows users to chat with their documents, providing summaries of long texts, extracting specific facts, and synthesizing information from multiple files. Another major feature is smart renaming, which suggests descriptive filenames for generic files like "IMG_001.jpg". Advanced media analysis lets users jump to specific moments in videos or search for text inside images. Because all AI processing happens on the device, user data remains private and secure without relying on external servers.

Use Cases

Dhito is ideal for anyone who needs to quickly locate information stored in their personal or professional files. It works well for creative professionals who need to find specific scenes in video footage, such as a sunset or a person speaking a certain language. Researchers and students can use the chat feature to query years of research papers or meeting notes to find specific facts or synthesize ideas. Business users can locate tax documents or contracts by describing their content. Photographers and videographers can search for visual elements like "sunset by the lake" without manually browsing through folders. The app also helps users organize their digital lives by automatically suggesting better names for files, making future searches easier. It supports a wide range of file types including PDFs, Word documents, images, videos, and audio files.

Pricing

Dhito offers a 14-day free trial for new users. After the trial period, the subscription costs approximately the price of a cup of coffee per month. There are no long-term contracts required, and users can cancel their subscription at any time. If a user cancels, they retain access to the service until the end of their current billing cycle.

Vibes

Users have responded very positively to Dhito, praising its ability to understand context and streamline their workflows. One user named Sarah said it was life-changing for her archives because she could find a video from three years ago just by describing the weather. Marcus highlighted the chat feature as magic, noting that he could query years of research papers in seconds while keeping his data local. Elena compared the tool to the kind of smart search Apple should have built, appreciating that it handles messy folder structures effortlessly. David mentioned that finding B-roll footage used to take hours but now he can simply type a description and get the exact result. Sophie called it a game changer for her workflow, especially because it can even search handwritten notes.

Additional Information

Dhito is built on the principle of sovereign data, ensuring that user information remains under their complete control. The application runs entirely offline once set up, requiring no internet connection for its core functions. It is designed to have a low impact on system performance, running indexing tasks in the background with low priority even while the computer is sleeping. The app only reads files and never modifies or deletes them, ensuring data safety. It leverages powerful AI models that run natively on the user's hardware, eliminating the need for external servers and enhancing privacy.
