About

Nobody wants generic, unverified AI slop on their website. That is the fear this was built around. Mastheads is an editorial pipeline, not an AI writer that hands you a first draft and stops. It researches the topic against real sources. It writes under a real named byline, in a voice you set. It passes the draft through fact-check, standards and editor desks before you ever see it, and every article arrives showing what was checked and what fell short. Then you press Publish. It publishes to seven platforms - WordPress.org, WordPress.com, Ghost, Webflow, Shopify, HubSpot and GoHighLevel - or hands you the drafts if you do not run a site. If you run more than one site, the unit here is the site, not the article: up to 20 from one dashboard, each with its own voice, language and country. Free 7-day trial, 10 articles, no card.

About

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.

Pros & Cons from Real Users

Pros

  • I’ve used Mastheads for 45 days to write articles and manage my news site. It’s been a useful part of my publishing routine, and I appreciate being able to use it for both writing and site management. My experience so far has been positive.
  • I’ve been using Mastheads for around two months, and the biggest thing that stands out is the quality of the writing. It does not feel like a typical AI writer that simply generates generic content from a prompt. The output feels much closer to editorial-grade writing, with better structure, research, sourcing, tone, and overall article quality. I especially like how Mastheads combines research and writing into one workflow. It can help find relevant information and sources, build a properly structured article, maintain a consistent writing style, check claims, and even generate supporting visuals. This makes it feel more like an AI editorial assistant than just another text generator. The interface is clean, the workflow is easy to understand, and it saves a significant amount of time when creating long-form content without sacrificing quality.

Cons

  • My experience has been positive so far. I’ve only used Mastheads for 45 days, so I can’t comment on how it performs over a longer period yet.
  • I haven’t experienced any major issues during my roughly two months of use. Because Mastheads has quite a few publishing and editorial features, it can take a little time at first to understand everything the platform can do. I would also like to see even more customization and advanced editorial controls added over time, but these are relatively minor points.

AI Writing Supported

In AI writing, most of the category stops at the draft. Mastheads does not. It researches before it writes and cites what it used. It writes under a named byline in a voice you set. Every article goes through fact-check, standards and editor desks that are allowed to hold it back, and it arrives showing what was checked and what fell short. The final say stays with the writer or editor. From there it publishes into any of seven platforms - WordPress.org, WordPress.com, Ghost, Webflow, Shopify, HubSpot, GoHighLevel - in any language.
