The best app for classroom whiteboards — for students and teachers.
Short answer
BoardSnap is a strong option for classroom whiteboard capture: students snap the board before it's erased, and BoardSnap AI produces a structured summary of the content. This works for lecture boards, worked math examples, and discussion maps. Microsoft Lens is the better choice if the goal is filing to OneNote or OneDrive for a class notebook workflow.
## The classroom whiteboard problem
Professors erase boards. That moment — when a full board of worked examples, diagrams, or discussion threads disappears — is a note-taking panic familiar to every student who's ever been mid-copy when the eraser comes out.
The phone camera solves the capture problem. BoardSnap solves the comprehension problem.
## How students use BoardSnap in class
During lecture: Take a quick snap of the board at key moments — after a worked example, before a topic transition, whenever the board has a diagram you need to understand. BoardSnap queues captures offline if the classroom has poor wifi.
After class: Open the project for the course. BoardSnap AI summarizes what was on each board. For math, it describes the equation and the steps. For a diagram, it describes the components and relationships. The summary is a starting point for study notes.
Before an exam: Ask BoardSnap AI questions about the board content across all your lecture captures. "What were the three conditions for X?" "Show me all the boards where we discussed Y."
## What BoardSnap is not good at for classrooms
- Math notation — LaTeX-style equations are parsed with mixed accuracy. Simple algebra reads fine; complex calculus notation may produce garbled output. For heavy math courses, a manual review step is essential.
- Shared class notebooks — There's no built-in collaboration mode. One person snaps, one person gets the summary. For sharing with classmates, export as plain text.
- Teacher-facing use — For teachers distributing class materials, exporting the summary as PDF or plain text and sharing via email or LMS is the current path.
## Microsoft Lens for classroom use
If the school or university uses Microsoft 365 and Teams, Lens integrates with Class Notebook in OneNote. Students and teachers can contribute captures to a shared section. This is a purpose-built education workflow that BoardSnap doesn't replicate.
## Bottom line for students
For personal note-capture and AI-assisted studying, BoardSnap. For sharing captures across a class or integrating with a school's Microsoft system, Lens + OneNote.
Frequently asked
Does BoardSnap work for math problems on whiteboards?
For basic algebra, geometry, and calculus notation, BoardSnap reads reasonably well. Complex symbolic notation (nested integrals, matrix operations, proofs with many symbols) is hit-or-miss. Always review the AI output for math content before relying on it for study.
Can a teacher share BoardSnap summaries with students?
Yes — via the share sheet. The summary exports as plain text that can be pasted into email, a class management system (Canvas, Blackboard), or a shared Google Doc. There's no native LMS integration.
