AI Tools for Content Marketing Agencies
Draft, humanize and check client content in one place, with seats for every writer and an API when volume grows.
StealthGPT is an AI writing toolkit for content marketing and SEO agencies. Writers draft with the SEO writer, humanize AI text so it matches each client's voice, and check it with the built-in AI detector. Owners manage seats from one team page, and high-volume client work can run through the StealthGPT API or inside Claude and Cursor over MCP.
Built for client content at volume
A seat for every writer
Max includes 3 seats and Enterprise 5, and you can add paid seats up to 20.
SEO content that reads human
Draft with the SEO writer, then humanize it so client posts read like your team wrote them.
Checked before delivery
Run every draft through the AI detector and see its score before the client does.
API and MCP for volume
Push client drafts through the REST API, or humanize inside Claude and Cursor over MCP.
