Where To Submit is a hand-checked collection of 1,800+ backlink sites with built-in AI auto-submit. The collection covers 1,000+ launch platforms, startup directories, AI tool directories and review sites, plus 1,200+ blog pages across 840+ domains that still accept comments. It also ships its own submission agent: an MCP server and open-source skills that let your AI agent fill in the submission forms for you.

The auto-submit works one site at a time, in your own browser. On each site it first searches for an existing listing of your product. Then it fills the form from a product profile kept on your machine, and only marks the site as submitted after it sees a confirmation page or email. It doesn't pay, create accounts or solve CAPTCHAs unless you allow it.

Each entry shows DR, estimated monthly visits, pricing, how the form works, and the link type where it has been checked. 460+ sites have tips from real submissions.

40 sites are fully free to browse. Pro costs $19.9 per month or $199 once and unlocks submit links, tips, comment page URLs and progress tracking. The skills are open source under the MIT license.
