Opin gives developers an AI-native way to understand users. Instead of manually reading feedback or waiting on product teams, you can drop in our Web SDK (one script tag or npm install) and instantly capture user sentiment at the exact moment it matters, feature usage, errors, onboarding, upgrades, cancellations, and more.
Once feedback is captured, Opin’s AI automatically:
- clusters themes
- identifies patterns
- extracts reproducible steps when possible
- prioritizes what impacts your customers most
- generates developer-ready summaries
So your engineering team can spend time fixing, shipping, and building, not interpreting scattered user comments.
Features developers love:
- Lightweight Web SDK — add NPS/CSAT widgets or custom triggers with one line of code.
- Event-based feedback capture — fire surveys at lifecycle events using JS hooks.
- AI-driven insight engine — converts noisy feedback into structured issues.
- Developer-centric summaries — clear, concise, actionable insight.
- Zero UI overhead — tools stay out of your way; everything is customizable.
Opin is built for dev-led SaaS teams, indie hackers, and technical founders who want to stay close to the user without drowning in raw feedback.
