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.
The versioned filesystem built for AI agents
A 100% POSIX-compatible mount so agents and sandboxes use familiar Unix tools, with persistence, sync and version history handled transparently underneath.
Fork a workspace in milliseconds to run dozens of agents on isolated branches, then pick the best result without file locking.
Snapshot the entire filesystem at every step and restore any past state with a single API call when an agent goes off track.
Pause any agent for review, build approval queues and policy gates, then resume from the exact same workspace state.
