How to chat with your documents privately — and trust every answer
Chatting with your documents means uploading your own files and asking questions in plain language, then getting an AI answer that points to the exact source it came from. With Tatsulok you do this privately: you upload your documents, ask a question, and read an answer where every claim is cited to the specific passage, with a highlighted preview and a link to the original. Your documents and prompts are never used to train AI, are encrypted at rest and in transit, and stay private by default.
What does it mean to chat with your documents?
Chatting with your documents means you ask questions in ordinary language and an AI reads across the files you uploaded to answer them, instead of you opening each file and searching by keyword. You can ask things like "what were the renewal terms in this contract" or "summarize the risks across these three reports" and get a direct answer.
The difference between this and a general chatbot is the source. A general chatbot answers from its training data, which you cannot verify. Tatsulok answers only from the documents you provide, and shows you exactly where each part of the answer came from so you can check it yourself.
How do you ask your documents questions and get cited answers?
You upload your documents — PDFs, Word files, spreadsheets, slides, and more — into a private knowledge base, then type a question the way you would ask a colleague. Tatsulok finds the relevant passages, reads them, and writes an answer that cites each source inline.
Every citation is verifiable. You can open the highlighted passage to see the exact text the answer relied on, and follow a link to the original document. Because the answer is grounded in your own files rather than generic web content, you can trust it for work where the source matters — legal, research, finance, compliance, and operations.
Why are cited AI answers more trustworthy?
Cited answers are more trustworthy because you can check them. When an AI states a fact without a source, you have to take it on faith; when it cites the exact passage, you can confirm the answer is correct and catch any misreading before you act on it.
Tatsulok is built around this principle. Instead of asking you to trust the model, it shows its work: every answer links back to the specific source in your documents, with the relevant text highlighted. Verification takes seconds, which is what makes the tool usable for high-stakes professional work.
Can you keep your documents private when using AI?
Yes. Tatsulok is private by default: your documents and prompts are never used to train any AI model, your data is encrypted at rest and in transit, and you control who has access and when content is deleted.
Nothing is shared unless you choose to share it. You decide which teammates can see a document or knowledge base, and you can revoke access or delete content at any time. This is the difference between a tool you can use for confidential material and one you cannot.
