A structured-document editor for AI agents. SuperDocs gives your AI 21 MCP tools and 4 workflow prompts to make section-precise edits — bold a specific paragraph, replace a single table cell, restructure a heading — without disturbing surrounding content. Tables, borders, alternating row shading, fonts, and inline styling all survive AI edits AND round-trip exports across .docx, PDF, HTML, Markdown, and RTF. Other capabilities: pre-signed URL upload/download (no context bloat for files >100KB), compact response mode for editing 100-page documents efficiently (~140× token reduction), multimodal vision on attachments, human-in-the-loop approval for sensitive edits, and multi-language editing across 16+ languages. Free plan: 500 ops/month, no credit card required.
