AI that produces real Word tracked changes
The only AI document editor producing real OOXML tracked changes. Your counterparty opens in Word and sees standard Accept/Reject revision marks. No plugins required.
- Real OOXML tracked changes, not PDF annotations
- Standard Accept/Reject in any Word client
- Paragraph-level precision operations
- Full revision history with batch commits
OOXML-level fidelity
Sphere doesn't generate text and ask you to copy it back. It operates directly on the OOXML structure of your Word document, the same internal format Microsoft Word uses for tracked changes. The result is a .docx file your counterparty opens in Word and immediately understands: standard revision marks they can Accept or Reject.
Precision editing operations
Sphere offers four document operations: replace (swap paragraph content with tracked changes), insert before/after (add new content at precise locations), and delete (remove paragraphs with revision marks). Each operation produces a tracked change. Visible, reviewable, and reversible.
- Replace: swap paragraph content with tracked changes
- Insert before/after: add content at precise locations
- Delete: remove paragraphs with revision marks
- Template variables: bulk replacement across documents
Batch commit semantics
Sphere uses a staging model inspired by version control. Edits accumulate in a batch, which you can review and commit atomically. This means you can make multiple edits, review the combined diff, and commit them all at once, or discard the batch and start over.
