Long-Form Source Material and Anchored Review Context Stay Together
Why It Matters
Review Long Documents without Losing Context.
Import long-form material, anchor feedback to exact passages, manage the review queue, and export a useful revision brief without separating comments from their source.
One Device-Owned Workflow
Import. Review. Resolve.
Each stage keeps the source passage, requested change, review status, and final revision guidance connected from import to handoff.
01
Import
Bring long-form source material into one review workspace from pasted text or a supported document format.
02
Review
Anchor asks, simplifications, rewrites, verification notes, and precise comments to the passage that needs attention.
03
Resolve
Work through the review queue and export a structured revision brief that preserves every decision and its original context.
