Yes. All 16 tools work without an account or a credit card. The grade calculators and the seating chart generator run in your browser, so the grades and names you enter aren't sent anywhere.
The free graders score one pasted essay at a time. GradeWithAI grades a whole assignment from Google Classroom, Canvas, Google Forms, or uploaded files (PDF, Word, slides, and photos of handwritten pages) and sends scores back to Canvas or Google Classroom after you review them. Its free plan grades 25 submissions every 30 days.
EZ Grader turns a raw score like 17/20 into a percentage and letter grade. The weighted grade calculator combines category grades by weight. The final grade calculator finds the score you need on a final exam. The semester calculator combines quarter and exam grades.
Rubric cells can be edited on the page before you print. The other generators show read-only results that you can copy into Google Docs or Word, print, or save as a PDF.
Nothing is saved to an account, because there is no account. The AI tools send what you type to an AI model to write the result, so leave student names and personal details out.
