What is Squarespace?
Squarespace adds AI site generation and LLM brand monitoring in the same quarter
Squarespace has spent the last six months layering AI into two distinct workflows: site creation and brand discoverability. Blueprint AI now generates personalized multi-page sites from brand personality inputs—colors, fonts, industry type—with industry-specific imagery across 1,000+ categories. Separately, AI Visibility lets users track whether their business surfaces in ChatGPT and Gemini responses, a monitoring capability built into the dashboard rather than delegated to a third-party tool. Commerce features have expanded in parallel, with installment payments and behavior-triggered email automation rounding out the lower end of the funnel.
What is Subbly?
Subbly's AI builder becomes interruptible, months after retention intelligence moved in-house
Development is uneven across the product. The AI Builder is where the recent motion is: model intelligence was upgraded in June, and August makes the agent steerable mid-run — a new prompt can be queued while it works and gets inserted between steps rather than waiting for the current one to finish. The subscription platform itself has been quieter since spring, when Subbly replaced a third-party churn model with an in-house one it measures as 68% more accurate, added a cancellation type setting for immediate versus end-of-period, and shipped biometric two-factor with anomaly detection.

Squarespace
6.3E-COMM
Squarespace adds AI site generation and LLM brand monitoring in the same quarter
◆ Current state
Squarespace has spent the last six months layering AI into two distinct workflows: site creation and brand discoverability. Blueprint AI now generates personalized multi-page sites from brand personality inputs—colors, fonts, industry type—with industry-specific imagery across 1,000+ categories. Separately, AI Visibility lets users track whether their business surfaces in ChatGPT and Gemini responses, a monitoring capability built into the dashboard rather than delegated to a third-party tool. Commerce features have expanded in parallel, with installment payments and behavior-triggered email automation rounding out the lower end of the funnel.
◆ Where it's heading
The pattern is AI applied at the moments non-technical business owners feel most stuck: starting a site, checking whether AI search finds it, and converting visitors who arrive. Squarespace is building toward a closed loop—generate, discover, convert—without requiring users to leave the platform. Image Studio in September is the first step toward in-editor AI content generation, which would extend the same pattern to ongoing page updates after launch.
◆ Prediction
The next likely move is in-editor AI copy and image generation for individual sections, closing the gap between Blueprint AI's site-creation workflow and the ongoing maintenance tasks that currently drive users to Canva or ChatGPT outside Squarespace.
Subbly
2.5E-COMM
Subbly's AI builder becomes interruptible, months after retention intelligence moved in-house
◆ Current state
Development is uneven across the product. The AI Builder is where the recent motion is: model intelligence was upgraded in June, and August makes the agent steerable mid-run — a new prompt can be queued while it works and gets inserted between steps rather than waiting for the current one to finish. The subscription platform itself has been quieter since spring, when Subbly replaced a third-party churn model with an in-house one it measures as 68% more accurate, added a cancellation type setting for immediate versus end-of-period, and shipped biometric two-factor with anomaly detection.
◆ Where it's heading
The builder work is converging on keeping a person in the loop while the agent runs rather than making the agent more autonomous — the stated motivation is course-correcting a run that is going wrong and avoiding wasted credits. That framing, credits as the cost of a bad run, is worth noting: it treats agent time as a metered resource the merchant is spending, which shapes what gets built next. The retention side has not seen comparable investment since the churn model landed in May.
◆ Prediction
Expect further mid-run controls on the builder along the same line — editing or cancelling a queued step, or rolling back a bad one — since the credit-waste problem this release names is only partly solved by inserting prompts.
