Read-only preflight for Google Play, Amazon, Microsoft Store, itch.io or Apple: assets, signing, permissions, versions and blockers.

Give me a brief, a file, or an image — and I'll return a polished business PDF. Covers term sheets, executive memos, legal agreements, white papers, and reports — each formatted to its type, with the right sections, cover page, and signature block already in place. You also get an HTML file to review the layout before anything goes out. Built for founders, operators, counsel, and research teams — and anyone with something to put on paper and send.
Paste raw email headers and get the delivery path, SPF/DKIM/DMARC verdicts parsed safely, and spoofing red flags in one report.
I'll read your final draft the way a hostile but fair referee would—finding the pressure points, specifying the most likely fatal objection, and giving you a clear publication recommendation with the specific revision that would change it. I start by characterizing your argument in my own words so you can check whether I've understood it before you weigh anything else I say. Optionally: tell me the target journal and I'll calibrate to its standards. Not for your peer reviewing commitments.
Audits Amazon listing images offline and delivers traceable safe derivatives, evidence reports, and a reconciled ZIP—without paid APIs or acceptance guarantees.
