Your iOS and Android apps have drifted. Parive shows you exactly where, and when.
Parive reads both native codebases and lines them up: every screen, feature, and behavior, aligned concept by concept, with a severity on each difference. It's running on Wikipedia's apps right now. No signup, real code, real analysis.
The preview analyzes wikipedia-ios and apps-android-wikipedia: two excellent apps that Wikimedia's teams build in the open. Their openness is what makes a public preview on real code possible, and we're grateful for it. They're not affiliated with Parive.
Today, no one knows all the gaps. Parive does, on day one.
Every product built twice has differences. Most are platform conventions or intentional divergence. The dangerous ones are neither, and they surface as bug reports, support tickets, and "why does Android do that?"
Parive aligns both apps concept by concept: present here, different there, missing on one side. Each difference gets a severity, ranked with evidence from your commit history and connected tools. When one needs a closer look, an agent investigates it across both codebases and reports back with receipts.
A picture of what each app actually does, not what everyone remembers it doing.
The comparison stands on a full inventory of both codebases: screens, features, a domain dictionary, user stories, each one traceable back to source. It reads like product documentation your team would have written with unlimited time.
And it will stay current on its own. When new features land, Parive will re-analyze what they touched and update the affected documentation. Freshness won't be anyone's job.
From difference to merged fix.
Pick a difference worth closing. Build the plan with a planning agent in a shared document, edit the same text together, approve it when it's right. An implementation agent writes the code and tests on the lagging platform and runs them until they pass. The result comes back as reviewable work: a plan you approved, a diff you can read, tests that prove behavior parity.
Prefer your own team or tools? Assign the approved plan to an engineer, or reach everything over the API.
Pick the gap
Start from a ranked difference with its evidence attached: where it lives in each codebase, and what it costs users.
Agree the fix
You and the planning agent edit the same plan document. Nothing runs until you approve it.
Reviewable work
Code and tests on the lagging platform, run until they pass, linked back to the difference and the plan.
The planning and implementation agents run in private demos today. Ask us and we'll show you, on your apps.
One source of truth for the product you built twice.
Documentation, tests, and domain language that are maintained, reviewed, and trusted. Your issue tracker, CI, and every agent your team runs ask Parive instead of digging through code and wasting time and tokens. The apps stop drifting because the thing they are both derived from is kept true. Porting a feature stops being a project and becomes a task you assign.
We're looking for ten teams.
You have native iOS and Android in production. We'll run Parive's analysis on your codebases, walk the results with you, and get your feedback to shape the product. You work directly with the founding team, in your Slack, on your priorities.
Thanks — a founder will reply within a day.
In the meantime, explore the preview.
