Prefer to try it directly?
Start for free and check Laura's suggestions on a synthetic example, without real student data, without risk.
Note: all figures are estimates based on your inputs and transparent assumptions (to be validated with pilot schools), not guaranteed results. Laura assists; the assessment stays a suggestion until the teacher gives final approval.
Frequently asked questions
- How accurate is the correction time calculator?
- The calculator uses your inputs and transparent, adjustable assumptions and returns a range (conservative to optimistic). These are estimates, not guaranteed results; the assumptions are validated with pilot schools.
- Is my data stored?
- The calculation runs entirely in your browser. No data is sent unless you actively request a PDF briefing. In that case we only process your email and the aggregated key figures, never student data.
- Does Laura save time through automatic grading?
- No. Laura speeds up capture and makes assessment suggestions with confidence scores. The final grade is always the teacher's (Teacher Final Decision).
