Audit trail

Strata preserves provenance directly in the sheet, tracing each edit to the exact page, phrase, or source evidence it came from. Reviewers can follow the chain from source material to workbook change without reconstructing the audit trail after the fact.

Bob’s FY2026 growth email


Hi Charles,

Following up on the latest plan review, procurement timing is still on track.

We estimate a 15.0% increase in spend for Product A next year.

I will send the vendor assumptions later this week.

Operate in context

Strata operates over your local files and workbooks, then pulls in the relevant business context from ERPs, company systems, inboxes, filings, and more. Outputs stay grounded in the actual materials behind the work instead of relying on chat memory.

Built for sensitive business data

Files stay local

Work without needing to upload sensitive files to the cloud.

AI requests use zero retention

Agent processing runs through zero-data-retention paths where available.

Customer data is not used for training

Files, prompts, outputs, and agent runs are not used to train models.

Values stay audit-ready

Edited and extracted values trace back to the source document, sheet, or row.

Agent observability

Follow agent activity in context, so every workflow stays transparent.

Work stays recoverable

If an agent makes an unintended edit, you can undo the work and move forward.
