Typical draft (300–350 annotations, one a day): 55 hrs saved a month (2.5 hrs/day × 22); Basic $29.9 ÷ 55 ≈ $0.54/hr.
Basis: 30 sec per annotation by hand; engine measured at ~45 sec for 508 annotations (≈0.09 sec each); ~90% automated, ~10% reviewed (also 30 sec each); 22 business days per month. The automation rate varies with annotation quality — clear, well-aimed instructions automate more; vague or ambiguous ones go to review.

The engine finds, compares and rewrites - you review and approve.

01

Batch processing in one click

Drop in the PDF and target doc; the engine recognizes, locates and rewrites every annotation. You just review the result.

02

Natural language, multi-script

"Delete this paragraph", "make it bigger", "change A to B" — the engine understands proofreading intent, not just text matching. Annotations and body text in English, Russian, German and more are handled the same way; mixed-language manuscripts are no exception.

03

Sync to three formats at once

Sync the same annotations to Word, IDML and Indd scripts in one pass.

04

Verification and rollback built in

Auto paragraph-level reconciliation after every run; accidental changes are flagged and can be restored in one click.

05

Smart disambiguation, less manual work

Ambiguity is resolved by context, anchor and page; only truly uncertain items go to human review.

06

Cancel anytime, no half-written files

The progress panel supports cancellation; interrupted runs never write partial files.

07

AI-assisted recognition

For vague annotations like "polish this sentence" with no explicit fix, AI understands the intent and suggests an edit - clearly labeled as AI-sourced, and applied only after your review. No black box, no overreach.

Four steps from annotations to finished files.

Import, parse, review, export - every step that needs judgment is yours to confirm.

I

Import PDF & target

Drop in the annotated PDF and pick the target document.

II

Engine parses annotations

Each annotation is classified, located and its instruction understood.

III

Human review

Ambiguous or uncertain items land in the review bucket for your confirmation.

IV

Export the result

Write back to Word / Indd in one click, keeping layout, with restorable backups.


Every change, trackable.

Delivery ledger

Every export produces a six-section ledger: how each annotation was handled (auto-applied / manually confirmed / not applied) with page-level locations, in TXT / CSV / HTML / PDF — statistics are cross-checked against the output before delivery.

Auto backup & restore

The original file is backed up before export; any run can be reverted in one click.

Project archive (annual & perpetual)

Past projects are archived, so sources, targets and results can always be revisited. Available to annual and perpetual license holders.

The engine reviews in seconds; you make the calls.

  • Hours saved

    The mechanical find-compare-transcribe work goes to the engine. The time you save is yours.

  • Verification and rollback built in

    The result is reconciled paragraph by paragraph against the backup; accidental edits are flagged and reversible.

  • Sync to three formats at once

    The same annotations sync into Word, IDML and Indd scripts in one pass.

  • Your document content never leaves this machine

    Only the annotation content, a small snippet of text immediately surrounding it, and check-sums are transmitted; the cloud processes and discards them — the full document never leaves this machine.

Save a few hours of proofreading every day - for your kids, your family, and yourself.

The engine never decides for you - ambiguity, uncertainty and judgment always stay with you. It only does the mechanical finding, comparing and rewriting. Every minute saved is yours.
