Choose the plan that protects your credibility
Así Echo works for both individual creators tracking their own content AND ghostwriters/agencies managing multiple client voices. Each author gets their own isolated ledger—something ChatGPT can never do.
For occasional publishers testing the waters
For active thought leaders publishing consistently
For ghostwriters and content creators managing multiple clients
For agencies, media companies, and teams managing dozens of voices
All plans include a 14-day free trial. No credit card required.
You connect your LinkedIn, X, Medium, and Substack accounts once. Echo ingests your publishing history and creates a semantic signature for each idea you've expressed. It doesn't just match keywords—it understands meaning.
Echo shows you exactly why: the collision type, which previous posts triggered the refusal, your credibility risk score, and specific recommendations. You maintain full control—Echo advises, you decide.
Absolutely. Echo is a continuity engine, not a content blocker. It provides informed guidance based on your publishing history. The final decision is always yours.
Yes—that's the point. Use ChatGPT, Claude, or any AI tool to draft content. Before publishing, run it through Echo to check for collisions with your existing work. Echo adds the memory layer AI tools lack.
You can manually add content to your Idea Ledger at any time. Echo will incorporate it into your semantic history and use it for future collision detection.
Plagiarism tools compare your text against others' work. Echo compares your new ideas against your own intellectual history to prevent self-plagiarism and idea exhaustion.
Each client gets a completely isolated author ledger. When you switch between clients in Echo, you're evaluating against ONLY that client's history—no cross-contamination. ChatGPT can't do this. It has no concept of separate author identities or isolated memory contexts.
ChatGPT has no persistent memory between conversations and no concept of separate author identities. You'd have to manually brief it on your entire publishing history every single time, and it still wouldn't understand semantic collisions. Echo maintains permanent, semantic memory for each author and detects idea exhaustion automatically.
