Why won't my manuscript send, or my beta reader's link work?

Manuscript upload errors

You can send DOCX, EPUB, PDF, HTML, TXT or MD files up to 25 MB. EPUB works best because its chapters are already marked.

  • That file type isn't supported. Export your manuscript to one of the formats above. Pages, RTF and similar files need converting first.
  • That file is over 25 MB. Remove large images, or export a text-only DOCX.
  • That PDF has no selectable text (it may be a scan). Export a text-based PDF from your writing app, or send a DOCX instead.
  • That EPUB looks damaged or That EPUB has no readable chapters. Re-export the EPUB, or use DOCX.
  • No readable text found in that file. The file opened but had no text. Check you chose the right file.

I can't pick my file from Book Storage

From Book Storage only lists supported files stored in the app's own storage. Files kept in Dropbox or Google Drive, or added from the old native apps, can't be sent yet. Download the file and use Upload a file instead.

The Send invite button is greyed out

Choose a book, and wait for Reading your manuscriptโ€ฆ to finish. If you write under more than one pen name, also choose which one to send as. The dialog will also ask for a reader name, a valid email and a due date in the future.

My reader says the session has ended

Once the due date passes, the reader sees This reading session has ended and can no longer read or comment. To give them more time:

  1. Click View feedback โ†’ on their row.
  2. In the readers list, find them and use Extend to to pick a new date.

They can use their original link again straight away.

My reader's link doesn't work

If a reader sees This link has expired or been replaced or Your personal reading link is needed, they can click Email me a new link. A fresh link goes to the email address you invited them with, and the old link stops working. New links can only be sent every couple of minutes.

My reader never got the invite

Ask them to check spam and promotions folders. The invite comes from Author's Toolbox with replies going to you. If the app showed Couldn't send the invite email. Try again., nothing was sent and you can try again. Sending is limited to 30 invites a minute.

"Please answer the required questions first"

A reader sees this when they click "I'm done reading" with a required question unanswered. Either they answer it, or you edit the question on the feedback page and untick Required.

Permission or subscription errors

  • You don't have permission to invite beta readers on this account. As a collaborator, you need edit access to Beta Readers. Ask the account owner.
  • Subscription required. Sending manuscripts needs an active trial or plan on the account.
