Memory Lane is a web app that helps people preserve, relive, and share their most important memories as walkable 3D spaces.

• Users upload a video of a meaningful room
• The app generates a 3D walkable version using Gsplat
• Users can narrate or write stories linked to the space
• AI remembers details and answers natural language questions
• Family and friends can contribute their own memories

• Gsplat for 3D scene rendering
• Google Gemini for memory narration and recall
• V0.dev for front-end development
• Selenium automation to wrap Vid2Scene (no public API)
• Twelve Labs for video understanding (experimental)

• Local rendering was too slow (30+ hours per scene)
• Built a custom wrapper to automate Vid2Scene via browser automation
• Learned and integrated unfamiliar tools under time pressure

• Add VR support
• Make objects in the scene clickable with voice or story links
• Create a simplified, narrated mode for elderly users
• Transition to Luma AI or similar for higher-quality rendering
