How do I add or reuse files in AI chat?

Tap the tools button next to the chat input and choose Camera, Photos or Files. You can also paste a link to a public PDF, image or shared Google file, and the AI chat reads it like an upload.

Updated November 6, 2026

Attach the material you want Knowie to use, then ask your question in AI chat.

Add a file or photo

  1. Tap the tools button beside the chat input. The Tools panel opens.
  2. Tap Camera, Photos or Files.
  3. Select your material, check the attachments and send your question.

To use something you sent before, open the earlier chat, or add the file again from your device.

Every file counts towards your upload allowance. See Limits for photos, files and messages in the AI chat.

Paste a link to a file

You can paste a link to a file in your message instead of uploading it. The AI chat downloads the file and reads it like an upload.

  • It reads PDFs and PNG, JPEG and WebP images, up to 5 MB each.
  • Google Docs, Slides and Sheets, and files in Google Drive, work if the link is shared so that anyone with it can open the file.
  • It reads up to two links in one message.
  • Links to web pages are not read as files. For YouTube videos, use the YouTube option in the Tools panel.

If the chat cannot open a link, for example because the file is private, larger than 5 MB or needs a login, the link stays in your message as text and the file is not read. Do not assume the answer is based on the file. Download the file and upload it with Files instead.

A photo is missing

On iPhone, Photos shows only the pictures you allowed Knowunity to access. If you allowed only selected photos, change the access for Knowunity in your iPhone settings under Privacy & Security → Photos.

If a local file is no longer available, choose it again from your device.
