Changes 1/2

Auditable by design

See every action before it lands. Strata keeps workbook changes legible with visible diffs, change summaries, and a clear review loop instead of burying edits behind an opaque run.

The point is not just automation. Teams can inspect every change, keep everything, or roll back everything in one move when a run is not ready.

Cross-file analysis

Ask questions that span a folder, not just the workbook currently open. Strata can read across related models, monthly files, source packs, and PDFs to assemble the context behind an answer.

That can make recurring analysis 5x faster or more, turning month-over-month bridges, vendor rollups, portfolio updates, and source-backed charts into review work instead of rebuild work.

Context available

What Strata keeps in view

Current view

The workbook, sheet, selection, or document in front of you

Related files

Other models, reports, PDFs, and folders in the workspace

Recent actions

What you just opened, reviewed, edited, or asked Strata to do

Memory

Team conventions, recurring workflows, and durable preferences

Past sessions

Relevant conversation history and prior run context

Operate in context

High-stakes spreadsheet work rarely lives in a single sheet. Strata understands the files, terminology, and conventions around the model you are working in, not just the active grid in front of you.

That means less setup, fewer ambiguous prompts, and more useful output on the first pass, with room for company-specific language, formatting preferences, and recurring workflows.

Local desktop

Context stays in your workspace

Workspace files

Models, PDFs, source packs

Reusable workflows and tool use

Strata server

Temporary slices only

No uploaded files

Nothing stays on the server. Only small temporary slices of data are used when needed.

Private by default

Strata is desktop-first by design. Your files stay in your local workspace or your company storage instead of getting rewritten into a hosted document system just to use the product.

That lets teams keep existing spreadsheet workflows while adding agent help, durable context, and auditability without pushing sensitive model context further away from where it already lives.
