Squarespace integrated its Blueprint AI Builder into ChatGPT's GPT Store (as Squarespace GPT) and announced a partnership with Perplexity's browser Comet, allowing users to begin a website-building conversation inside those external AI platforms before transitioning to the Squarespace editor.

Squarespace GPT, available in the ChatGPT Store, asks users questions about their business name, industry, brand tone, and goals through a conversational interface, then passes this information to Blueprint AI Builder to display a personalized site preview before users continue in the Squarespace editor. Separately, Squarespace announced in October 2025 a partnership with Perplexity, under which Squarespace serves as the website building and hosting partner for Perplexity's Comet browser, allowing users doing AI-powered research in Comet to transition directly into building a Squarespace site. Both integrations are free and do not require a Squarespace account at the start.
