You can attach files and photos to any message and ask TachlisAI about them. For example: summarize a PDF, pull numbers out of a spreadsheet, or explain what's in a photo.
How do I attach a file?
- Select + next to the message box.
- Choose one:
- Photos: pick a picture from your photo library.
- Camera: take a new photo (where your device has a camera).
- Upload file: choose any supported file.
- Wait for the upload to finish. Send stays unavailable until every attachment is ready.
- Type your question and send.
You can also drag files into the message box on a computer, or paste an image you've copied. To remove an attachment before sending, select its remove button.

Can TachlisAI listen to a recording?
Yes. Attach an audio recording, such as a voice memo from your iPhone, and ask about it. TachlisAI picks up what's said and other details in the audio. It can even suggest which melody a recording might be, though those matches are only a guess. Recordings must be 5 minutes or shorter. If yours is longer, trim it and try again.
Why won't my file upload?
- "Unsupported file type": the format isn't supported. Try saving it as a PDF, or as a common image or spreadsheet format.
- "File exceeds…": the file is over the size limit in the table above.
- The upload stalls: TachlisAI stops a stalled upload and lets you retry it. Check your connection, then try again. See Messages or uploads won't send.
Note: File uploads need a free account. They aren't available in the homepage trial.
