01 / problem

interior designers were spending 3-4 hours per moodboard

interior designers manually searched for furniture products, downloaded images one by one, placed them into presentation slides, calculated pricing from spreadsheets, and sent everything to clients. the process was repetitive, slow, and error-prone.

one moodboard could take an entire afternoon — leaving no time for actual creative work.

02 / solution

paste a url. get a client-ready moodboard in minutes.

built a full saas platform where designers paste product urls, n8n automation workflows orchestrate the entire scraping and data pipeline — connecting product urls to the moodboard canvas without a single manual step. playwright scrapes product data and images automatically, ai performs furniture inpainting to place selected pieces realistically into room photos, google sheets syncs pricing automatically, and the final moodboard is generated as a client-ready presentation. the entire workflow that took 3-4 hours now takes under 30 minutes.
