Marknote — inbox for your AI agents

Marknote is the inbox for the documents your agents ship — briefs, code reviews, research, and dashboards in markdown or HTML, hosted the second they're written. Read, edit, and share from your phone. No IDE, no deploy.

StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 17 June 2026; the live site may have changed since.

Marknote — inbox for your AI agents has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on June 17, 2026. The site is hosted on Cloudflare in the United States. Our crawler found 10 technologies on this site, covering auth, CDN, DNS providers, and business email. The stack includes Auth.js, Next.js, and React.

Notably, it's one of 53 launches on this exact stack.
