Frequently asked questions
Do I need drawing software?
No. These tools help you look, compare, and practice. Draw on paper or use your own drawing tools. The reference analysis is not your finished artwork.
Are my photos uploaded or saved automatically?
No. Photos are processed in this browser. Keeping a project on this device or continuing in another tool is an explicit choice. Transfers expire after 12 hours; saved projects remain until you or your browser clears them. Keep important work in a downloaded backup.
What does a project backup include?
Your current settings, crop, selected studies, and reflection. Choose to include personal photos if you want them to reopen without selecting the originals. Unknown project versions and unsupported images are rejected without replacing your work.
Does the tool grade my drawing?
No. Comparisons describe shapes, proportions, timing, or digital colors. They are prompts for observation, not a score of artistic ability or a promise of learning results.
