Review steps in Apps
Apps can pause at a checkpoint for a person to review. An App’s author marks any block as a review step; when the run reaches it, the App stops and waits for someone to read the output, edit it if needed, and approve it before the downstream blocks continue. It is the human-in-the-loop safeguard that catches a small error early, before it cascades through the rest of the deliverable.Sourcing in the document viewer
A pass over how sources are presented. Opening a citation lands you closer to the passage it points at, and citations stay readable where several of them sit close together in the same paragraph. See Sourced Answers.The Mainframe
Our biggest release since launch. The Mainframe is a central orchestration agent: it works out what your request needs, gathers it from across your documents, the web, and your spreadsheets, then hands a complete set of materials to the step that writes your answer. It shows its work end to end with a card for every capability it uses, and it powers both Chat and Apps. It brings:- Iterative smart search that loops until it has surfaced all the relevant context.
- A brainstorming mode with no data sources, for thinking work that stays entirely within the EU.
- A web research mode that reads across many sources in a single pass.
- Excel analysis with code for advanced calculations and search across complex datasets.
- Document comparison that reports what changed between two versions, ranked by how much each change matters.
- Conversation memory with fast, in-context follow-ups.
Slide generation from App blocks
App blocks can now produce presentation slides as a native output, built on your firm’s slide templates. An App designer links a block to a template, and the finished run exports as a ready-to-share deck, so a workflow can go from inputs to a formatted PowerPoint without leaving VirtualBrain.
