Beta Reader LabChapter 7

The rain had been falling since noon, turning the platform silver beneath the station lights.

Marcus stopped at the doorway. Someone had moved the suitcase.

“Did you touch that?” Elena asked.

He shook his head, but he wouldn't look at her.

Beta reading shouldn't end with a scattered email, a few margin notes and “the middle felt slow somewhere.”
A clearer feedback loop

Read. Notice. Tag. Return.

Beta Reader Lab gives readers a simple structure without turning beta reading into homework.

01

Open the manuscript

Create a project and import the author's manuscript text.

02

Read naturally

Navigate chapters with automatic progress syncing. When you reopen the app, your exact position is restored. For audio review, select the Read Aloud option to listen for errors or pacing issues.

 

03

Highlight what matters

Simply highlight the passage you want to respond to.  A feedback window appears instantly, ready for you to choose a tag and leave your comment.

04

Send it back

Export a portable .brl feedback file containing comments and big-picture feedback for the author.

Structured, not restrictive

Say what you noticed. Make it easy to find.

Instead of forcing every observation into the same comment box, Beta Reader Lab lets you tag feedback by type. Authors can see not only what you said, but what kind of issue or reaction you were flagging.

Global feedback

This is the moment the chapter clicked for me. I wanted the next reveal immediately.

For authors

A beta reader shouldn't need to buy your writing software.

Beta Reader Lab is the free side of the Indie Writer feedback workflow. Give readers a purpose-built way to review your manuscript, then bring their structured feedback back into your author workflow.
