Chat with Word, PDF and CSV File Content Using Advanced AI
DeepFA's AI file chat tool lets you upload Word, PDF and CSV files and directly chat with AI about their content. No need to read entire documents or copy text. Just upload the file and ask your question: "What is this financial report summary?", "What are the key points of this contract?", "Analyze the second table data" — and AI responds based exactly on the text and data in the file. This tool is incredibly useful for lawyers, data analysts, students, researchers and executives dealing with long documents and data files.
DeepFA's AI file chat supports the most advanced OpenAI model family including GPT-4o, GPT-4, GPT-3.5 Turbo, GPT-5 and lightweight mini and nano versions. You can choose the right model based on processing speed, response accuracy or cost. The brand voice feature allows you to generate summaries and responses in your brand's unique tone and style. Voice input also enables asking questions by microphone instead of typing.
The process is very simple: upload your file, the system extracts and processes the text and data, and you can immediately start chatting with AI. Responses are provided solely based on the file content without using the model's general knowledge. Chat history is saved so you can return to previous conversations at any time.

What is AI File Chat and what is it used for?
From uploading Word, PDF and CSV files to smart summarization and data extraction — everything you need to know about document analysis with AI.
DeepFA AI File Chat is a specialized tool for focused conversation with your file content. The key difference from regular chatbots is that the entire conversation revolves around the uploaded file, and AI provides answers solely based on that file's text and data — without mixing in its general knowledge. This is crucial for lawyers, data analysts, students, researchers and executives dealing with long documents, financial reports, contracts and CSV files, as it guarantees answers stay within the document scope and are fully attributable.
The tool supports three main formats: Word (DOC/DOCX), PDF and CSV. After upload, the system extracts text and tables, and AI becomes ready to answer. You can ask questions like "What is the summary of this contract?", "What are the key points of this financial report?", "Analyze the data in column three of the table", or "What is the main conclusion of this scientific paper?" You can also switch AI models among GPT-4o, GPT-5, o1 mini and others, use voice input instead of typing, and receive summaries in your brand's tone via Brand Voice.
Three main formats: Word, PDF and CSV — all professional needs covered
Word formats (DOC and DOCX) for text documents and reports, PDF for contracts and scientific papers, and CSV for tabular data and spreadsheets. AI fully understands and analyzes text, tables and structure of all three formats.
Smart summarization of long documents in a few lines
Instead of reading a 50-page document, just say "summarize". AI extracts the most important sentences, paragraphs and results as bullet points or a few concise lines. Reduce contract, report and paper review time by up to 90%.
Extract and analyze data from tables and CSV files
Have a CSV file and want to find patterns, averages or trends? Just ask "calculate the average of column three" or "which month had the highest sales?". AI also analyzes tables inside PDF and Word files.
Focused document conversation without going off-topic
Unlike general chatbots that may mix external information into answers, DeepFA File Chat AI answers solely based on the uploaded file — fully attributable and free from out-of-context errors.
Choose the AI model that fits your needs
Default model is GPT-4o. Need higher accuracy? Use GPT-5. Speed is important? Pick GPT-4o mini. For analytical and mathematical problems, o1 mini is best. All models support file analysis.
Voice input — ask questions without typing
Don't feel like typing? Just click the microphone icon and say your question. AI converts voice to text and answers. Ideal when you have many follow-up questions.
Privacy and data security — your files remain confidential
Uploaded files are used only for that conversation and are deleted after the conversation ends or upon your request. Your data is never shared with others.
For professional use of File Chat, start by uploading your file and asking general questions like "summarize" or "key points". If you need more detailed analysis, switch the model to GPT-5 or o1 mini. For large files (over 50 pages), use models with larger context windows like GPT-4. You can upload several different files in separate conversations, and each history is saved independently. You can combine analysis results with other DeepFA tools like content generation and brand voice for a more professional final output.
