Strella Changelog – September 11, 2026

Watermark sensitive stimulus

Image, video, embed, and prototype blocks have a new Watermark option in their Advanced section, so a leaked screenshot or recording of sensitive stimulus traces back to one person.

Edit a saved report in AI Chat

Reports saved from AI Chat now have an Edit action in their menu that opens the report back up in AI Chat, so you can keep refining it.

Coded-response filters show their question

In the participant filter picker, each coded-response filter now reads as its question followed by the coding name, so you can tell what it matches. Labels too long for their row show in full on hover.

Small fixes

• Importing a study document: the Build assistant now turns a study document into a guide question for question, in your wording and order, instead of summarizing it, and screening questions land on the Screener tab
• Pasting screenshots: you can now paste an image straight into the message box in the project setup chat or the Build assistant
• Analysis during busy periods: when the AI model is briefly out of capacity, analysis now tries again instead of leaving out an interview summary or a question's themes
