Does Lettie integrate with agentOS?

agentOS already has maintenance jobs. What does Lettie add?
Lettie takes the tenant's WhatsApp report, sets the urgency and talks the tenant through simple fixes in the chat, such as topping up the boiler pressure. For the rest, it chases the contractor, books the visit and gets the landlord's sign-off, at the stages you hand it.
50% of repair cases are first reported outside 9am to 5pm, Monday to Friday (Lettie data, Jun–Aug 2026). Lettie replies at any hour, with a median first reply of 26 seconds (Lettie platform data, Aug 2026).
When a repair needs your team, agentOS gets a maintenance job, a tenant note or both, whichever you switch on.
Will our landlords see Lettie's name in agentOS?
No. Jobs and notes Lettie creates in agentOS use neutral wording, without Lettie's name or links.
What goes into the agentOS job?
When a repair needs your team, Lettie creates an agentOS maintenance job on the property, a note on the tenant, or both, as you set up. The job gives the report number, the problem, its priority (Low, Medium or High) and current status, what's affected and where, the recommended next action, the tenant's name and number, and how many photos and files are on the Lettie report.
How quickly do agentOS changes reach Lettie?
Within the hour, as Lettie checks agentOS every hour, or straight away if you press Sync now.
