Write Your Fantastic Thesis is the operating system for finishing your thesis. Start with your deadline, word target, current progress, available working days, university guidance, marking rubric, outline and supervisor feedback. WYFT turns them into a living plan that shows: • The date you are currently likely to finish • How many words and hours you need each week • Whether you are ahead or behind • One concrete, realistic task for today • Which chapter, evidence gap or feedback item creates the most risk BUILD A LIVING THESIS MAP Organise chapters, sections, word allocations, milestones, evidence requirements and revision status in one place. TURN SOURCES INTO USABLE EVIDENCE Create structured source cards, preserve quotations with page or source locations, map claims to evidence and record conflicting findings or limitations. MAKE SUPERVISOR FEEDBACK ACTIONABLE Convert broad comments into specific revision tasks, prepare meeting agendas and keep a decision history so important choices are not lost. RECOVER WHEN YOU FALL BEHIND WYFT redistributes missed work, tests recovery scenarios and updates your predicted finish date as you log real research, drafting and revision sessions. PROTECT ACADEMIC INTEGRITY WYFT critiques structure, reasoning, clarity and evidence. It does not fabricate sources, hide AI authorship or write a submission-ready thesis for you. FREE TO START Build your thesis setup, inspect the generated completion plan and complete the first two guided outputs before choosing WYFT Pro.
