You can bring documents into a conversation in two ways. Attach a file to hand Mesa a one-off document for the current conversation only, or tag a file you’ve already saved to Mesa so you can reuse it across as many conversations as you like without re-uploading it.

Attach a file

On the Home or New Conversation page, click the paperclip icon in the chat box and select the files you want Mesa to use, or drag and drop them into the chat box.
If a file won’t upload as an attachment, add it through Files instead, or check whether it needs to be converted to a supported document format first.

Tag a file in a conversation

1

Open the chat box

Go to the Home page or New Conversation page.
2

Open the file picker

Click the @ symbol at the bottom-left of the chat box, or type @ directly and select Select from my files.
3

Choose your file

Select the file you want Mesa to reference.
4

Finish your prompt

Continue typing and send your message. Mesa uses the tagged file in its response.
To organize the files you can tag, see Files.
The @ picker isn’t the only way to reference something. Almost anything in Mesa with its own page (a file, a conversation, a report, a dataset, or a piece of Library content) has a copy link button next to its title. This is the quickest way to pull the exact thing you’re looking at into a new conversation.
1

Copy the link

Open the item you want to reference and click the link icon next to its title.
2

Paste it into a conversation

Go to a chat box and paste. Mesa recognizes the link and turns it into a reference to that item, the same as if you’d tagged it with @.
3

Finish your prompt

Keep typing and send. Mesa uses the referenced item when it responds.
A link always points at the item’s current version, so a reference you paste today stays accurate even after the underlying file or report changes. See Version history.
