How teachers capture whiteboard class notes without slowing down the lesson.
Short answer
Teachers traditionally photograph whiteboards at the end of class and email the image to students. BoardSnap is an iOS app that goes further: it snaps the board, reads every diagram and list, and returns a clean written summary students can actually read and search — all in about ten seconds.
The teacher's whiteboard is the most information-dense surface in a classroom. By the end of a 50-minute period, it might hold a vocabulary framework, a diagram of a process, a worked example with annotations, and a list of homework items. Then someone erases it.
Teachers who want to share board content with students typically have three options:
- Photograph the board and post the image to Canvas/Google Classroom (students can't search or copy from it)
- Re-type everything after class (takes 20-30 minutes per session)
- Use a smart board with screen capture (expensive, and not every room has one)
The BoardSnap approach
At the end of class — or at natural breakpoints — the teacher opens BoardSnap on their iPhone. VisionKit straightens the perspective and handles the glare typical in classroom lighting. One tap later, BoardSnap AI reads every element on the board: diagrams, arrows, numbered problem steps, vocabulary lists.
The output is a clean text summary. Post it to your LMS, share it as a PDF, or use it as the basis for a lesson recap email. Students who were absent get real content, not an image they can't zoom into.
Projects keep the class organized. Create one project per course. All boards from that course — from September through May — live together, searchable, with their summaries. At finals time, students and teachers both have a structured record of what was actually taught.
Pinned context lets you save the course syllabus or key framework once. Every future AI chat in that project uses it as background — useful for generating study questions from a recent lesson's board content.
This workflow works equally well for tutors, teaching assistants, and professors running office hours on a small whiteboard.
Frequently asked
Does BoardSnap work in dim classroom lighting?
Apple VisionKit's perspective correction handles most classroom lighting conditions including overhead fluorescent glare. For very dark rooms, the iPhone's camera handles focus and exposure automatically. Bright, direct lighting produces the sharpest captures.
Can students use BoardSnap too, or is it only for teachers?
Both. Students who take their own notes during class can snap lecture boards, study diagrams from textbooks, or capture mind maps they draw while studying. See the student use case page for the student-specific workflow.
