61 editing skills trained on your thesis
Every sentence, citation, and structural choice — reviewed by specialised editing skills and returned as track changes. You decide what to accept.
Generic AI tools were not built for thesis editing
They cannot produce track changes. They do not understand thesis structure. They offer no developmental critique. And they certainly do not follow professional editing standards.

IPEd/CIEP compliant
Our editing approach follows the standards set by the Institute of Professional Editors and the Chartered Institute of Editing and Proofreading.
Meaning preservation
Prooflo edits language, not ideas. Your argument, analysis, and conclusions remain entirely your own work.
Confidence thresholds
Each edit carries a confidence score. Low-confidence suggestions are flagged as comments, not applied as changes.
Diff verification
Every edit is verified against the original text to ensure nothing was lost, added, or semantically altered.
Developmental Edit
A structural analysis of your thesis across five dimensions, framed as questions for you and your supervisor to consider.
Argument Coherence
Does your argument flow logically from premise to conclusion across chapters?
Critical Analysis
Are you engaging critically with the literature, or summarising without evaluation?
Contribution
Is your original contribution clearly articulated and evidenced throughout?
Alignment
Do your research questions, methodology, and findings align consistently?
Structure
Does your chapter organisation support your argument effectively?
Based on examiner assessment research by Lovitts, Mullins & Kiley, and Holbrook & Bourke.
