Three ways to bring files into a chat
The plus button holds every way of giving Metir something to read. Which one you pick depends on how many documents there are and how deeply you need them read.
Good afternoon
Type @meeting, @note, or @file to pull context into any chat.

The plus menu
On the Website, the menu lists these actions from top to bottom. The first four add something to your next message; the last three, below a line, change how Metir works in the chat.
- Upload from computer, pick files from your machine.
- My Files, browse files you have already saved in Workspace.
- Recent attachments, scroll back through files you attached in recent chats and Orb tasks, newest first, and tick as many as you need.
- Artifact, attach a document, deck or spreadsheet Metir made earlier. See slide decks.
- Deep Research, choose a folder or a larger set of documents for research.
- Connectors, switch connected apps on for this conversation. See connectors in a chat.
- Amnesia, send with no memory or context. See Amnesia.
Each file you attach can be up to 500 MB, on the Website and on mobile.
On mobile, the sheet starts with a row of photos you can swipe sideways. Tap Camera to take a photo or Photos to choose one; on iPhone your most recent photos follow, so you can tap a few and press Done.
Below the photos are two groups. The first is Upload files, to browse your phone's storage, then My Files and Artifact; each shows a count once something is attached. The second is Deep Research, Connectors and Amnesia. Deep Research shows what it covers once it is on, Connectors shows how many are on (or Set up when you have none yet), and Amnesia is a switch. A loading spinner can appear beside Connectors while that choice becomes available.
Which one to use
| You have | Use |
|---|---|
| One to a few documents you want read end to end | My Files |
| A file on your computer you have not saved yet | Upload from computer |
| A folder, a library, or a question shaped like "everything about X" | Deep Research |
The full-file limit
There is a cap of 20 files read in full in one message, counting files you have already attached as well as the ones you are picking. When you reach it, Metir offers to move the whole set into Deep Research instead. You review the selected items and wait for them to become ready before adding the set to the chat. See what Deep Research is.
What an attached file looks like
A picture the browser can display arrives as a thumbnail you can click to see full size. Everything else arrives as a card with the file type, its name and its size, which is also what you get for camera formats a browser cannot preview. A file still uploading shows its progress in place, and one that failed offers to retry rather than quietly vanishing.
Not every model takes every kind of file. Audio and video only go to the models that can hear and watch, and Metir tells you which when you try. Programs are never accepted. See choosing a model.
The indexing dots
Every file in the picker carries a small dot showing whether it has been indexed. Green means indexed and ready. A small spinner means it is being read right now. Grey means it is waiting its turn, a hollow dot means it has not been indexed, and red means it could not be. An amber dot on a folder means only some of its files are indexed. Deep Research can only use indexed files, and the picker will index them for you. See adding and indexing files.
Uploading a zip
Upload a zip and it is unpacked into a folder named after the archive, with its internal folders kept exactly as they were, so a research library you already organised on your computer arrives organised here too.
