Attachments
Attach a file, a recording or existing work to a chat, see how Endless reads each kind, and know who can see an attachment afterwards.
Anything you attach stays available for the rest of the conversation, so you don't need to attach it again for a second question.
Attach something
- Add menu: select "Open add menu" next to the composer, then "Attachments". This opens a picker over your Library, with its search and filters, and an "Upload file" button.
- Drag and drop files anywhere over the chat.
- Paste a screenshot or copied image into the composer. A copy that also carries text, such as a spreadsheet selection, pastes as text.
- Library panel: "Show library" opens the library beside the chat. Select "Use in chat" on a tile, or drag the tile onto the conversation.
Existing files come from the picker, not from @. See mentions.
What you can attach
| Kind | Size limit | How Endless reads it |
|---|---|---|
| Images | 100 MB | Looks at the picture, so you can ask about it, edit it or use it as a reference. |
| Documents and text (PDF, Word, Excel, CSV, Markdown, JSON) | 100 MB | Extracted as text. Scanned PDF pages are read with OCR, up to 100 pages per file; Endless is told which pages it skipped. |
| Video and audio | 2 GB | Not watched automatically. Endless looks at it when the question needs it. For speech, make a transcript instead. |
- Up to 20 files per batch. A larger batch is refused with "You can upload up to 20 files at a time". Further batches add up, with no total limit per message.
- A file over its size limit is refused with a message naming the file and the limit.
- Documents can be dropped silently well below 100 MB. If Endless answers as if a document isn't there, split it or attach only the part you need.
- If the chat's model can't read images, sending is blocked with "…can't analyze images. Pick another model". Switch model and send again.
What happens to an attachment
- Uploaded images, video and audio are saved to the Library, private to you.
- Documents from your device are used by the chat but not added to the Library. To keep one, upload it in the Library first and pick it from there.
- Anyone who can open the chat can view files you attached that you own. Attaching a file you can only view gives nobody new access. Attaching never makes a file public or editable by others. See assets and visibility.
If an attachment won't send
- "Wait for the upload to finish before sending": an image, video or audio file is still uploading. Send again in a moment. A document still uploading doesn't block you: its chip reads "Sending when the upload finishes".
- "An error occurred while uploading an attachment. Retry or remove it first": select the chip to retry, or remove it.
- "An attached file can't be sent. Remove it and try again": an older library item a model can't read. Attach a current one.
Uploading needs the Library turned on for your workspace and permission to create content. A Viewer can't upload. See roles and permissions.
