Files in chat

Uploading Files#

You can upload files directly in the chat input area at the bottom of the chat window. You can either use the upload button or paste a file, image, or screenshot straight from your clipboard (for example, right after copying a screenshot). Pasting adds the attachment immediately, so you often don’t need to save it locally first or pick it from a file dialog. However, please note the following limitations:

• The file size should be kept small, as LLMs have a limited context window.
• For larger files or datasets, use datarooms instead of chat attachments.
• Archives such as ZIP files cannot be attached in chat. Upload them to a dataroom instead.

Opening Uploaded Files in Preview#

Files you upload directly into a chat message can be clicked to open them in the file preview, the same viewer that is used for dataroom files. This lets you quickly check the content of an attachment, including a PDF preview for Word, Excel, PowerPoint, and supported OpenDocument files, without downloading it first.

Temporary Uploads & Token Limits#

Files you add here are treated as temporary context for this conversation only; they are not stored like dataroom documents. Attachments are deleted automatically 7 days after upload. Save a file to a dataroom to keep it.

Every model has a maximum number of tokens (characters and words) it can consider at once. If your uploads + chat history exceed that limit, the model will respond that a file was “too large” / “not fully processed”.

How to adapt:

• Split long documents into smaller targeted files
• Remove unnecessary pages (keep only the section you need)
• Ask a narrower question (e.g., “Summarize the milestones section” instead of “Summarize the whole 60‑page report”)
• Move extensive analysis to a dataroom where full processing is possible
• Upload fewer files at once for critical accuracy

If you need persistent access, versioning, or comprehensive coverage, switch to a dataroom before continuing.

Reusing and Saving Attachments#

When composing a message, you can reuse attachments from previous messages in the same conversation rather than re-uploading them. You can also permanently save an attachment to a dataroom for future use across conversations.

Attachments in Dataroom Chats#

You can attach files and images temporarily to individual messages even while a dataroom is connected in the chat. This makes it easy to ask a question that combines your stored dataroom knowledge with an ad-hoc document or image, all in the same conversation.

Large Plans and Drawings#

AITEZA reads large plans and drawings, such as building plans or piping and instrumentation diagrams (P&IDs), region by region, so that even small labels are read reliably. Ask any question about a plan in a connected dataroom or attached to the chat, for example:

• Look up a detail: “What is the nominal size of line 4711?”
• Follow a line: “Where does the line from pump P-101 lead?”
• Count or list: “List all valves with their tags.”
• Check or summarize the whole drawing.
• Compare two plans or revisions: “What changed between revision B and revision C?”

AITEZA zooms into regions at full resolution, searches PDF plans for tags, line numbers and other text, goes through the whole sheet tile by tile for questions about the entire drawing, and lays two plans or revisions on top of each other to mark what differs. Revisions and scans are aligned automatically.

Live View#

As soon as AITEZA works on a plan, select Open the live view of the drawing in the chat header. The actual file opens next to the chat and follows every region AITEZA looks at. The tiles AITEZA has checked, its findings, the places it found and the regions that changed are marked; a comparison shows both drawings.

• Previous view and Next view step through the regions; Go to current view returns to the region AITEZA is looking at now.
• Show the whole sheet shows the entire page.
• AITEZA’s markings hides or shows the markings.
• On touch screens, zoom with two fingers.
