ProofWrite
ProofWrite is an AI research and writing platform built for SEO agencies, link builders, guest post providers, and content marketing teams.
It helps create researched, cited, fact-checked SEO articles and publisher-ready guest posts built around a keyword, client URL, or anchor text.
Unlike generic AI writers, ProofWrite follows a research-first workflow: it gathers source material, plans a relevant article angle, writes from evidence, checks claims, adds citations, and reviews link placement so drafts read like genuine editorial content rather than AI filler.
ProofWrite is designed for guest posting, niche edits, digital PR, SEO agency deliverables, client content workflows, and multi-site publishing.
