Thesisroom is a web-based thesis checking tool designed for Master's and doctoral students in any academic field. The application provides stage-specific analysis that covers the full research process, from topic selection through the final defense. Users upload thesis chapters or reference lists, and the tool identifies issues such as argument structure problems, unresolved gaps, and citation errors. Each issue is displayed alongside the specific passage it came from, allowing students to see exactly what needs attention in their own text. The application operates through several distinct functions. The Research Compass helps students survey existing published literature before choosing a topic, returning paper counts and thematic groupings for a search query. The Chapter Audit reviews argument structure within submitted chapters, flagging issues such as an acknowledgement of a gap without full resolution. The Defense Practice function generates questions similar to what an examiner or committee might ask, referencing specific pages and hypotheses within the student's thesis. A citation checking feature allows users to upload a chapter or reference list and receive a marked report of issues tied to the original text. All changes remain the student's responsibility to make, and the thesis text is never used to train any model. Thesisroom offers a free tier that requires no account and no credit card to try. After the trial, paid plans are available at $9 per month billed annually or $12 per month on a month-to-month basis. The interface organizes work into rooms corresponding to each stage of the thesis process, from choosing a topic through defending the work. This structure guides students through a workflow that begins with upload and ends with a list of concrete fixes to address.
