How ‘Process Feedback for Google Docs’ extension compares to others

In the early days of digital writing, Draftback was a revelation. It showed us that a Google Doc was not just a static file, but a living history. However, simply “watching a movie” of a student’s typing is not enough. We (and our students) do not just need a video; we need a map of the learning process.

Although our Google Docs extension was partly inspired by Draftback, the broader Process Feedback project emerged from a gap in pedagogical research rather than from existing tools. Our framework, published in Education Sciences and summarized on our research page, proposes using visual analytics to understand how students write and code.

We prepared this article because many teachers and institutions ask us: What makes Process Feedback different?

1. Research and pedagogy

This is the “brain” of the tool. Most trackers were built as utilities to see what changed. Process Feedback was built from a pedagogical foundation to help teachers understand the effort behind the writing.

2. Pricing and accessibility

We believe that pedagogical tools should be accessible to everyone, not hidden behind a “per-user tax.”

  • Revision History: ⚠️ First 150 documents free, then requires a paid plan.
  • Draftback: ⚠️ Now a paid service (roughly $40-$100/year).
  • Process Feedback: ✅ Free for individuals. Institutional agreements are flat-rate and do not depend on student headcounts.

3. Privacy and data sovereignty

In an era of constant data harvesting, we took a stand: your data belongs to you.

  • Draftback: ⚠️ Requires active-user email collection for subscriptions and trials.
  • Revision History: ⚠️ Requires name and email at sign-up for accounts and subscriptions.
  • Process Feedback: ✅ Zero data collection by default. Everything works locally on your machine.

4. Detailed analytics vs. simple replay

Watching a 3-hour video of a student typing is a burden. We replace “video watching” with “data visualization.”

  • Revision History: ⚠️ Offers playback and “unusual writing” detection, but lacks deep visual summaries.
  • Draftback: ⚠️ Offers ‘playback’ as its primary feature.
  • Process Feedback: ✅ Provides rich charts like “Edit Time and Location” describing evolution of sentences and paragraphs to see drafting and revision efforts at a glance.

5. AI-assisted exploration of the writing process

We view AI as a potential ‘reflection partner’ for students and teachers.

  • Revision History / Draftback: ⚠️ No native support for guided AI reflection comparable to Process Feedback’s workflow.
  • Process Feedback: ✅ Includes a unique “Copy for AI” option to analyze writing patterns safely.

6. LTI integration

Institutional adoption depends on how well a tool talks to your Learning Management System (LMS) like Canvas, Moodle, or Blackboard.

  • Revision History & Draftback: ⚠️ Not known to support standard educational integration protocols.
  • Process Feedback: ✅ Supports Standard LTI v1.3, allowing for seamless, secure integration within your existing institutional workflow.

7. Formatted text in playback/replay

For writing teachers, seeing the “structure” of the writing (including text formatting such as bold, italics, font sizes, text alignment, etc.) is part of the feedback process.

  • Revision History: ⚠️ Limited playback formatting.
  • Draftback: ⚠️ Not available; often strips formatting during the playback process.
  • Process Feedback: ✅ The only Google Docs extension that restores formattings like bold, font size, and text alignment during playback.

8. Standalone editor

Sometimes you may need to analyze a process outside of the Google Workspace ecosystem.

  • Revision History & Draftback: ⚠️ Entirely dependent on the Google Docs environment.
  • Process Feedback: ✅ Includes its own online editor (and even an online compiler) that is accessible without requiring an account, providing flexibility for different classroom activities or privacy needs.

9. Teacher dashboard

Process Feedback supports large classes by letting you load multiple students’ writing-process ZIP files at once into a teacher dashboard. This allows you to review, compare, and discuss students’ writing processes efficiently—without opening the reports one by one.

  • Revision History: ⚠️ Not available.
  • Draftback: ⚠️ Not available.
  • Process Feedback: ✅ Available. Our teacher dashboard feature provides a birds-eye view of student activity and works locally, meaning it provides powerful insights without ever collecting or storing user data on our servers.

The Bottom Line: At its core, the difference is intent. Other tools are built for “version control.” Process Feedback is built to improve students reflective and reflexive thinking. We focus on the pedagogy of revision.
