Ivory Mind, formerly known as Coral AI, is an AI document assistant for uploading PDFs, Word files, presentations, audio, and video, then asking questions and getting cited answers. Every response includes clickable page-number or timestamp references so you can verify the source.

You can chat with individual files or bulk-upload your library and search across 100+ documents in one conversation. The platform supports 20+ file types, OCR for scanned PDFs and handwriting, audio and video transcription, and content generation from your source materials.

Ivory Mind is trusted by over 500,000 researchers, academics, and professionals. The free plan includes 2 file uploads; the Executive plan at $12 per month (billed yearly) adds unlimited uploads, bulk chat, and 150 audio or video transcriptions per month.

MarketMuse is a content research and planning platform that scores your entire site inventory and tells you which topics to create or update next. Its patented models measure personalized difficulty, topic authority, and competitive gaps based on your published pages rather than generic keyword volume alone. Teams use it to build content plans, generate briefs, and prioritize updates where they already have an edge.

Most SEO suites stop at keyword lists and one-page audits. MarketMuse starts from your full inventory, compares coverage against competitors, and ranks opportunities by how hard they would be for your domain specifically. That personalized difficulty score (1 to 100) is the trade-off: more setup than a lightweight keyword tool, but fewer wasted articles on topics you cannot realistically rank for.

The product fits content strategists, SEO leads, and editorial teams at brands publishing at scale. A free tier offers 10 queries per month for solo users, while paid Optimize, Research, and Strategy plans add tracked topics, monthly content briefs, and strategy documents for growing teams.
