AI can build a prototype in an hour. But turning feedback into action - whether it's your own review or input from others - is still the slow part. Spikes makes feedback structured, precise, and agent-ready.
The problem: describing visual issues in chat is imprecise. "Make that card bigger" - which card? How much bigger?
Click the element. Leave a comment. Your agent gets the exact CSS selector, bounding box, and context to act on it.
The problem: feedback is scattered across WhatsApp, email, Slack - all screenshots and vague descriptions you have to translate.
Share one link. Reviewers click elements and comment. You get structured JSON to paste straight into your agent.
From "I don't like that card thing" to a PR in minutes, not hours.
The prototype is the easy part now. Spikes handles what comes next.
Built something over the weekend? Share it with friends, collect their reactions in one place, iterate with Claude.
Stop chasing feedback across WhatsApp and email. One link, structured comments, faster revisions.
Product, design, stakeholders - everyone reviews in the browser. Feedback goes straight to implementation.
