How to Organize Documents for AI Chat: Projects, Not One Big Pile

Most people start with one chat and keep adding files to it — a contract here, a set of lecture slides there, an unrelated report next. The tool doesn't know these belong to different topics, so a question about the contract can pull in a passage from the lecture slides just because the wording is similar. To organize documents for AI chat well, you group related files together and keep unrelated ones apart, the same way you'd use separate folders instead of one desktop full of files.

Tools built around this idea call the grouping a project or a notebook: a container that holds a set of documents and the conversations you have about them, so retrieval only ever looks inside the topic you're actually asking about.

1. Create a project for each topic — a course, a client, a research question — before you upload anything.
2. Add every file, link, or video relevant to that topic to the same project, whatever the format.
3. Start a new project instead of reusing an old one when the subject genuinely changes.
4. Use separate conversations inside a project for separate lines of questioning, so a chat thread doesn't wander between unrelated threads of the same topic.
5. Revisit old projects instead of re-uploading the same files into a new one — the documents and past answers are still there.

• Same project:sources that answer the same kind of question — a report and the sources it cites, a course's slides and readings, a client's contract and related correspondence.
• Separate projects:topics that would confuse a search if mixed — two different clients, two unrelated courses, last year's project versus this year's.
• When in doubt, split it out. A smaller, more focused project retrieves more precisely than a large one where every question has to sort through irrelevant material first.

Even inside a well-organized project, one question doesn't always need every source. A good document Q&A tool lets you tick just the files relevant to a specific question in the sidebar, or attach a source directly to the message you're sending, so that one answer draws only from what you selected instead of the whole project. That's a second, finer layer of organization on top of projects themselves — useful once a project grows past a handful of documents.

Doxy is built around exactly this structure: create a project for each topic, add PDFs, Office files, web links, and videos to it, and ask questions that stay scoped to that project instead of bleeding into unrelated material. It's the same principle behind questioning a whole library at once — see what to look for in an AI research assistant for more on multi-source projects, or how document Q&A with citations works for the question-answering side once your sources are organized.
