Gantra とは？

Gantra is a team of twelve marketing agents and one rule: nothing ships without you. They audit your SEO, ask ChatGPT, Perplexity and Gemini whether they recommend you, and draft your articles and social posts after reading your site. Every draft waits in one feed: you calibrate, approve, schedule. Your corrections stick, so week three sounds like you. Accepted SEO fixes can leave as GitHub pull requests. The free plan runs real audits every day, forever, no card.
