Simulation, evaluation, and RL training infrastructure for AI browser agents
Pixel-perfect, reproducible browser environments that eliminate web drift, noise, and rate limits so agent runs are comparable over time.
Every action is tracked, classified, and tagged — click failures, layout shifts, and misfires are surfaced rather than silently swallowed.
Human annotators build custom, long-horizon training data for supervised fine-tuning of browser agents on real enterprise platforms.
Safely sample and evaluate large numbers of trajectories to train browser agents at scale, without running into anti-bot constraints.
AI-assisted email and SMS marketing that turns audiences into customers
Drag-and-drop templates, reusable layouts, and guided steps to design and send newsletters or promotional emails without a designer.
Build automated journeys triggered by signups, purchases, birthdays, or inactivity, including welcome and abandoned-cart series.
Generate draft copy and subject lines, and use data-driven send-time suggestions to improve engagement.
Tag, segment, and filter contacts, and track engagement history in a searchable audience database.
