sendhey hosts the interactive prototype, PRD, or spec your agent just built as one gated link for execs, engineering, design, and any external stakeholder in the review — with private in-context feedback turned on and the same URL carrying every new version through the sprint.
A PM's agent doesn't just describe a feature, it builds a clickable prototype or writes the PRD and the accompanying spec. Publish the actual HTML/JS prototype with publish_page rather than exporting a video walkthrough or a static image — a reviewer clicks through the real thing. See sharing AI prototypes with clients for the prototype-hosting details this page assumes.
Feedback is on by default, so a stakeholder leaves comments and pinned annotations directly on the prototype, PRD, or spec. Each comment starts private to you; a stakeholder can choose to make theirs public so other reviewers see it too, and a new link allows that choice by default so a shared review thread works without extra setup (turn it off to keep every comment private regardless). That keeps a design review or a PRD comment thread out of a separate doc-comments tool nobody checks.
A prototype or a spec goes through two or three revisions before a review lands; republish to the same link each time and stakeholders who already have the URL see the current version, with no "PRD v3, please ignore v2" message required.
An early spec or a roadmap-adjacent PRD sometimes needs to stay inside the company or inside one partner's domain before it's ready for a wider audience — restrict the link to named people or a company domain the same way you'd gate a client deliverable, and open it up once the work is ready to share more broadly.
Yes — feedback and annotations never require a viewer account; only your workspace does. Whatever gate you set for access, commenting is available to anyone who gets past it.
Yes — republish the same page (or push new files to the same bundle) and the existing share URL keeps working; nobody needs a new link for the next version of the prototype, PRD, or spec.
sendhey doesn't replace your prototyping tool, your doc editor, or your roadmap software — it's the shareable, gated review link around whatever your agent already built, whether that's a prototype, a PRD, or a spec. It doesn't run a build step or server-side logic beyond a static bundle. See sharing AI-generated work with clients for the general workflow.
