Turn any website into an installable PWA — no coding required
Every PWA gets a unique install page that recreates the app-store experience without the store review process, working across iPhone, iPad, Android, Mac and PC.
Compose, preview, schedule and send push notifications to iOS, Android, Windows and macOS, with subscriptions auto-synced to your own user data.
Produces maskable icons, correctly sized macOS icons and all 26 iOS splash screens automatically, so the app looks right on every device.
Set up the web app manifest with toggles and inputs rather than code, and add custom install buttons and permission prompts without development work.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
