When you're done, you can send a summary immediately or have SiteWalk bundle all of your site walks into a single daily email. No typing. No paperwork. No manual uploads. Just walk, talk, and keep moving. Key Features Multi-Language Narration Speak naturally in whatever language your crew uses. Bynaus AI transcribes and understands your walkthrough automatically. Automatic Photo Intelligence Every photo is instantly titled, captioned, and tagged. You never have to label or rename anything.

SiteWalk uses these to organize your photos and narration so every walkthrough aligns with how that project is actually managed.
