User Intelligence to Product Action — in one flow.
Custo uncovers the silent issues hurting your users most, and gives anyone on your team the tools to immediately fix it.
How it works
Everything you need to go from problem to fix — without the noise.
Custo detects issues automatically. Then gives you three ways to act on them — instantly.
Automatic issue detection
Custo connects to PostHog and watches your session replays. Every rage click, dead click, drop-off, and error gets flagged automatically — ranked by how many users it's hurting. Get Slack notifications for critical issues.
Launch a widget
Guide confused users, announce a fix, collect feedback, or upsell a feature — directly from Custo. 19 purpose-built widgets across 5 types. Live in minutes, no code needed.
Copy a code fix prompt
For broken buttons, errors, and crashes, Custo generates a precise prompt scoped to the exact file and issue. Paste it into Cursor or Claude Code — your AI agent writes and ships the fix.
Create a Linear ticket
When a fix needs to go into the engineering backlog, Custo creates a Linear ticket pre-filled with everything your team needs — no write-up, no context lost, no back-and-forth.
How it works
From PostHog to fix in under 10 minutes.

OAuth in one click. Custo pulls your last 30 days of events and session replays automatically.
STEP 02
Issues surface instantly
Custo's AI analyses your data for rage clicks, dead clicks, drop-offs, and errors — ranked by severity and user impact.
STEP 03
Pick your fix
Code fix prompt for Cursor or Claude Code. Widget for immediate UX action. Linear ticket for the backlog.
STEP 04
Ship it
No handoff. No waiting. You go from spotting the problem to having a fix live — in the same session.
What we believe
Understanding your product and
improving it should be the same act.
We're enabling the person with the most context to act on what they know.
No false positives.
Custo cross-references event frequency, affected user count, and interaction pattern against a severity model — so only issues with consistent, reproducible signal make it through. If it's in your feed, it's real.
We don't interrupt you if it doesn't matter.
You'll get a Slack alert when it's a critical issue. You can also set your own alert threshold.
Ship it today. Users won't wait till next sprint.
Context is freshest now. Copy a prompt into Cursor or Claude Code and have a fix live before standup.
