01 · The claim

Your whole team can change the product. Engineers still merge.

Marketers, designers and CRO specialists make the change on your real app. It lands as a pull request.

For teams running a real app with real customers.

02 · The loop

Stop writing tickets for padding.

Most round trips between you and engineering are about how it looks, not whether it works. Those are the changes the person who wants them could make in a minute.

Merged.
a working week6 hand-offs, mostly waiting
the same afternoon1 hand-off: the review

A typical small change — copy, spacing, placement. Give or take.

03 · The change

One change, start to finish.

Someone asks in plain words: an A/B test, variant B on the new design system. The preview redraws. A pull request opens for review. The same afternoon, no ticket.

A change playing in the workshop: someone asks for "Set up an A/B test on the landing page. Variant B uses the new design system: dark hero, rounded corners, the blue accent.", the files are edited, the preview of your app is redrawn, and pull request #413 is opened for review.

04 · Your app

AI app builders make new apps. We change yours.

AI app builders start a fresh JavaScript project on their own stack. bigpencil opens the app you already run, in the stack it is written in.

  • A prompt. A new app, on their stack.
