Thoughtline provides a Chrome extension and teacher dashboard that makes the writing process visible within Google Docs, serving as a process-based alternative to AI detectors. Instead of returning a probability score on finished text, Thoughtline shows how a draft began, developed, and was revised, allowing teachers to coach students with context. The tool is teacher-facing and requires no student installation, integrating directly into existing Google Docs workflows.

Problem
Teachers currently rely on AI detectors that assign probabilities to finished essays, but these tools frequently produce false positives, particularly for multilingual and Black students, and offer no insight into the actual writing process. This leaves teachers without the context needed to distinguish authentic student work from AI-generated text, eroding trust and undermining coaching conversations. The finished product does not reveal where an idea started, how it changed, or what the student understands.
Solution
Thoughtline provides a process-visibility alternative to AI detection by showing how a student's writing developed inside Google Docs. The Chrome extension gives teachers a readable view of how the writing session began, how different types of content (Original, Assisted, Other) appear across the draft, and where revision occurred. A cloud-based teacher dashboard extends this visibility across classes and assignments, organizing process patterns into clear signals that focus teacher attention. This approach allows teachers to make their own professional judgments about student work, supported by observable process context rather than a probability generated from finished text.
Target Audience
Primary users are educators, writing instructors, and instructional leaders in middle schools, high schools, and higher education who need to understand student writing processes in order to provide feedback and coaching rather than rely on AI detection. The tool is designed for teachers who work with Google Docs and need to support diverse student writers, including multilingual learners.
Features
- Chrome extension that reveals the writing process inside Google Docs without requiring students to install anything or learn a new platform
- Document view showing how the draft began, developed, and changed through revision, with categorizations for Original, Assisted, and Other content
- Class and course dashboards that extend process visibility across assignments, enabling teachers to focus on coaching moments
- Process-oriented design grounded in research on recursive writing, formative feedback, and revision, explicitly avoiding AI detection claims or accuracy scores
- Teacher-facing workflow that leaves interpretation and next steps to the educator, supporting conversations about permitted AI use and multilingual composing
