Core features

Complete visibility into
every user session.

Coryn AI combines secure session replay, rich context, and powerful filtering so your team spends less time guessing.

01

Secure Session Replay

Replay exactly what your users experienced without recording screenshots. Sensitive UI elements stay private by design.

Every interaction, in context
02

Rich Session Context

Capture device state, network quality, screen transitions, feature flags and custom metadata alongside every replay.

The details behind the behaviour
03

Crash Investigation

Jump directly from crash reports to the exact user session that caused them, with full debugging context.

From symptom to root cause
04

Performance First

Designed for minimal battery usage, low storage overhead and negligible impact on app performance.

Lightweight by design
Why Coryn AI

See the full story behind every issue – what the user did, how the UI responded, and the exact sequence that led to a crash, bug, or unexpected state. Coryn AI brings session replay, app context, and debugging together so your team can move from symptom to root cause in one place.

Built for the real world

Built for the complexity
of real-world apps.

Powerful session replay infrastructure that stays accurate, lightweight and under your control. Coryn handles the difficult edge cases behind the scenes, from dynamic Android interfaces to long-running sessions, so you get reliable replays without adding complexity to your app.

01

Privacy that moves with your UI

Sensitive elements stay precisely masked as layouts move and resize. Coryn AI synchronises masking with the UI lifecycle before frames are captured – and automatically rejects a capture rather than risk exposing an incorrectly masked view.

  • Handles keyboards, split screen, popups and bottom sheets
  • Supports overlays, nested views, maps, videos and WebViews
  • Detects dynamic layout changes before capture

Native Android intelligence

Track custom states and events using the Android SDK lifecycle rather than manually wiring every state change. Coryn automatically follows State Provider updates and integrates with Compose without requiring additional tracking logic.

  • Automatic lifecycle-aware state tracking
  • Custom states and events alongside every replay
  • Seamless Compose integration with no additional logic

Performance without Compromise

Sessions can run from the moment your app opens until it closes, while Coryn dynamically adjusts capture performance to stay within CPU limits. Control capture behaviour remotely without rebuilding or releasing your app.

  • Unlimited session duration with optional programmatic controls
  • Adaptive capture up to 30 FPS based on device performance
  • Remotely control FPS and capture by app or version using feature flags

The details make the difference

Little things.
Powerful difference.

Developer Context

Every replay includes device information, network changes, orientation changes, memory state and your own custom metadata.

Powerful Search & Filtering

Find the exact session you're looking for using user IDs, app versions, feature flags, crashes, custom events and more.

Privacy by Design

Only your application's layouts are captured. Passwords, messages and sensitive UI can be hidden with a single command.

Built for Mobile Teams

Designed for Android first with minimal performance impact and seamless SDK integration.

Analytics Integration

Connect sessions to analytics events, crashes and feature flags to understand behaviour instead of guessing.

From the teams building better apps

Built for modern
engineering teams.

Our team was worried about performance overhead and battery drain. Collecting precise context can be demanding, especially on older Android devices. But thanks to adaptive capturing, we haven’t experienced any issues.

How is Coryn AI different from traditional screen recording?

Coryn AI doesn't record screenshots or your user's entire device. Instead, it securely reconstructs your application's UI, allowing you to replay user sessions while keeping sensitive information and content outside your app private by design.

Does Coryn AI affect app performance?

Coryn AI is designed with performance in mind. The SDK is lightweight, optimized for minimal CPU, memory and battery usage, so users can continue using your app without noticeable impact.

Can I hide sensitive user information?

Yes. You can exclude specific UI elements such as passwords, payment fields, messages or any custom views with a single command. If Coryn AI cannot guarantee that sensitive content is hidden, it discards the capture instead of uploading it.

Can Coryn AI integrate with our existing tools?

Absolutely. Coryn AI is designed to complement your existing workflow. Integrate it with crash reporting, analytics and feature flag platforms to jump directly from an issue to the exact user session that caused it.

How long does it take to integrate Coryn AI?

Getting started only takes a few minutes. Add the SDK, configure the basic settings, and you'll begin capturing secure session replays. You can gradually enrich recordings with custom metadata, feature flags and user context as your integration evolves.
