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. Replay is useful, and many teachers also want a summary they can read quickly and discuss with students.
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
Process Feedback was designed around research on giving feedback about the writing process, not only the finished draft.
| Tool | Research behind it |
|---|---|
| Revision History | We have not found peer-reviewed papers describing its design |
| Draftback | We have not found peer-reviewed papers describing its design |
| Process Feedback | Described in peer-reviewed papers, starting with a 2023 paper in Education Sciences |
2. Pricing and accessibility
Cost matters, especially for teachers who pay for classroom tools themselves.
| Tool | Pricing |
|---|---|
| Revision History | First 150 documents free, then a paid plan |
| Draftback | 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
This compares what each tool asks for or stores when you start using it.
| Tool | Data collected |
|---|---|
| Revision History | Name and email at sign-up for accounts and subscriptions |
| Draftback | Email for subscriptions and trials |
| Process Feedback | None by default. Everything works locally on your machine |
4. Detailed analytics vs. simple replay
Replaying a long document can take a lot of time. Charts give a summary that is quicker to read.
| Tool | Analytics |
|---|---|
| Revision History | Playback and “unusual writing” detection; few visual summaries |
| Draftback | Playback is the main feature |
| Process Feedback | Charts such as “Edit Time and Location” that show how sentences and paragraphs developed, so drafting and revision are visible at a glance |
5. AI-assisted exploration of the writing process
We view AI as a potential ‘reflection partner’ for students and teachers.
| Tool | AI-assisted reflection |
|---|---|
| Revision History | No built-in option for guided AI reflection |
| Draftback | No built-in option for guided AI reflection |
| Process Feedback | Each section has a Copy button. It copies the section’s data and chart with a reflection prompt, ready to paste into any AI chat |
6. LTI integration
Institutional adoption depends on how well a tool talks to your Learning Management System (LMS) like Canvas, Moodle, or Blackboard.
| Tool | LTI support |
|---|---|
| Revision History | Not known to support LTI |
| Draftback | Not known to support LTI |
| Process Feedback | Supports LTI 1.3 for secure integration with your LMS |
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.
| Tool | Formatting in playback |
|---|---|
| Revision History | Limited |
| Draftback | Not available; formatting is often stripped during playback |
| Process Feedback | Restores formatting like bold, font size, and text alignment |
8. Standalone editor
Sometimes you may need to analyze a process outside of the Google Workspace ecosystem.
| Tool | Works outside Google Docs |
|---|---|
| Revision History | No; depends on Google Docs |
| Draftback | No; depends on Google Docs |
| Process Feedback | Has its own online editor (and an online compiler), usable without an account |
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.
| Tool | Teacher dashboard feature |
|---|---|
| Revision History | Not available |
| Draftback | Not available |
| Process Feedback | Multiple options |
Our teacher dashboard feature provides a bird’s-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: Draftback and Revision History are useful for replaying how a document changed. Process Feedback also offers charts, a class dashboard, and reflection prompts, because it is designed to help students reflect on how they work.
