Use cases
Any app, adapting to the person using it - inside boundaries you set.
Onboarding that improves with every user
Watches where users stall, and rebuilds the flow for the next person who looks like them.
An inbox, reshaped around you
Watches what you reach for. The actions, views and content you use surface; the rest fades.
A CRM, rebuilt around how you work.
A sales CRM becomes an investor’s CRM. Fields adapts, relationships surface, the logic rewires. Same data, different app.
Catches what broke in prod
A backend change breaks an export. Differ sees it live and repairs.
From the least worst version for everyone to the best version for anyone.
How it works
Import
Connect a GitHub repo. Differ assesses fit, clones it, and runs it on a managed runtime. You set the guardrails: what's in scope to adapt and what stays off-limits.
Observe
Every user gets their own anchor. Differ watches behavior: clicks, navigation, flows repeated, and clusters it into signal.
Adapt
When a signal is real and within the bounds you set, an agent proposes a change with rationale and cited evidence. Schema, auth, and runtime shape are off-limits by default.
Diverge & deploy
Differ commits the change to a per-user version of your app, builds it, boots it, and routes that user to it. Your stem stays untouched.
One stem. Many lives.
Your app stays canonical in your repo. Differ derives an adapted version per user — keeping the stem untouched.
The baseline
Your app, exactly as it is in your repo. Differ calls it the stem. It never changes.
The adapted versions
The same app — but it learns from real usage and adapts its UI to each person using it.
