Board Snap

Photograph whiteboards, get clean digitized notes with text extraction

Useful

Instant

Privacy

The Problem

Whiteboard content is lost when erased; photos are low quality; content isn't searchable

Current Solutions (Not Great)

Phone photos (bad quality), Microsoft Lens (cloud), dedicated whiteboard cameras ($$$)

Who Needs This

Knowledge workers, meeting participants, students, workshop facilitators, agile teams

You just had a great brainstorming session, but the whiteboard will be erased. Board Snap captures whiteboard content and transforms it: perspective correction for angled photos, contrast enhancement for faded markers, glare removal, and—most importantly—text and diagram extraction. Get a clean digital image plus the actual text and structure recognized. Handwritten notes become searchable text. Diagrams are identified and described. Never lose whiteboard wisdom again.

Honest Take

Microsoft Lens and Adobe Scan already own this space, but they're cloud-based. The technical challenges are real—glare removal and perspective correction on whiteboards is trickier than it sounds, especially with glass reflections. Decent niche for privacy-conscious teams and remote workers, but you'll need killer image processing to compete.

Build Prompt

Use this prompt with an AI assistant to start building

Build a React PWA called 'Board Snap' using WebInfer with vision capabilities. UI: camera with whiteboard detection overlay, capture preview with enhancement options, archive gallery. Capture: detect rectangular whiteboard edges (Canny edge detection + Hough lines), show alignment guide. On capture: 1) Perspective correction (four-point transform on canvas), 2) Enhance contrast (adaptive histogram equalization), 3) Remove glare (detect bright spots, interpolate from surroundings), 4) Clean background (threshold to white). Send enhanced image to vision model. Use generateObject to return { extractedText: string, textBlocks: [{ text: string, position: {x,y}, type: 'heading'|'body'|'list' }], diagrams: [{ type: 'flowchart'|'mindmap'|'drawing'|'chart', description: string, position: {x,y,width,height} }], stickyNotes: [{ color: string, text: string, position: {x,y} }], overallSummary: string }. Display: enhanced image with overlay toggles (show extracted text regions, diagram bounding boxes). Archive in IndexedDB: image, extracted data, timestamp, tags. Search: full-text search across all extracted text. Share via Web Share API: image, image+text, text only. Export: PNG, PDF with OCR text layer, markdown. Multi-shot stitching for large boards.
