Chatd.ai

Chatd.ai is an AI chat bot tool. An open source desktop app that lets you ask questions about files on your own computer using a local AI model, with no uploads and no cloud dependency.

Chatd.ai is a desktop tool for asking questions about files stored on your computer without sending anything to a cloud service. The pitch is straightforward: the model runs locally, it reads the document you point it at, and the back and forth stays on the machine. The homepage frames this as "your own private local AI that can read files on your computer," and the demo conversation shown is a summarization request answered from a short document about the solar system. The intended user is someone who handles material they would rather not upload: contracts, internal notes, research drafts, personal records. Anyone who has hesitated before pasting a sensitive file into a hosted chatbot is the target audience here. Because there is no upload step, the tool also works without a network connection once it is set up, which matters for people on restricted machines or unreliable connections. In practice the workflow is a single window: load a file, type a question, read the answer. The demo suggests the assistant quotes or works from the document text rather than general knowledge, so follow-up questions about the same file are the natural use case. It is an open source project, published on GitHub with a visible star count in the low thousands, so the code can be inspected and the app is free to build from source. Where it fits: this is not a competitor to the big hosted assistants on model quality or breadth. It competes on privacy and control. Against other local chat applications, it is narrower, with a single focus on reading documents rather than general conversation or plugin ecosystems. That narrowness is the appeal, but it also means users accept hardware requirements, manual setup and a smaller feature surface in exchange for keeping their files at home.
