What it is

A review layer for anything with a URL

VizHound opens your prototype in a viewer and makes every element commentable. What comes out the other side is structured enough for a machine to act on.

Comment on anything

Click any element in the live prototype and drop a Figma-style comment with tags. No screenshots, no annotation apps.

Every comment carries the context

Each note records the exact selector, the computed styles, and a screen grab. The feedback knows what it points at.

Export fixes, not screenshots

Turn a review session into an AI-ready fix prompt for Claude, v0, or Cursor — or a task list for Trello and Jira.

How it works

Three steps, no setup

  1. 01

    Paste your link

    Drop in the URL of your prototype — v0, Lovable, Replit, or anything with a link. It opens in the VizHound viewer.

  2. 02

    Click to comment

    Point at the thing that's wrong. Tag it, describe it, grab the screen. VizHound captures the element underneath.

  3. 03

    Export to your AI or PM tool

    One click turns the session into a fix prompt you paste into your AI tool, or a task list your team can pick up.

Why it matters

Collecting prototype feedback is copy-paste chaos

Notes land in five different chats. Screenshots lose the element they point at. Meanwhile your AI tool could fix most of it instantly — if it knew exactly what and where. VizHound closes that gap.

What people say

“The button looks off.”

Which button? Off how? On what screen?

What your AI gets

Fix: primary CTA misaligned
Element:  button.cta-primary
Selector: main > section.hero > button
Styles:   padding 10px 20px; margin-left 3px
Note:     "The button looks off — nudge it
          back onto the grid"
Screen:   grab attached

Who it's for

Built for people who ship prototypes

Vibe coders

You build in v0, Lovable, or Cursor. Feedback should land in the same loop your AI works in.

Indie makers

Send one link to early users and get back comments pinned to real elements, not vague DMs.

Product teams

Review prototypes together and walk away with a task list instead of a screenshot thread.

Agencies

Give clients a place to point at things. Every note arrives with the context your devs need.

Early access

Built for the tools you already use

Exports are formatted for the places vibe-coded prototypes get built and fixed.

  • v0
  • Lovable
  • Replit
  • Cursor
  • Claude

VizHound is in early access

It's free, there's no account, and your feedback shapes what gets built next. The best way to judge it is to point it at your own prototype.
