HVACVisor vs OneNote OCR — Quick Breakdown (2025)
OneNote’s OCR is old-school. It works okay for whiteboard notes and clean handwriting, but it absolutely cannot parse shop drawings, schedules, or tightly packed engineering text.
HVACVisor is built around those exact challenges.
Where HVACVisor Wins
- OCR on dense mechanical layouts
- Reads tags, callouts, wire labels
- Handles low-quality scans
- Works with field photos (blurry/angled)
- Doesn’t “skip” half the text
Where OneNote Wins
- Handwriting OCR
- Free
- Works offline
- Good for basic notes capture
