HOW IT WORKS
Three steps. About fifteen minutes from sign-up to a live agent on your number.
01
Drop in your knowledge.
Upload PDFs, paste text, or add product docs. Your agent has them on hand within seconds.
02
Teach it to sound like you.
Write a short role prompt and set escalation rules. Refunds, upset customers, and low confidence can pause for a human.
03
Get a real iMessage number.
Sendline provisions the line for your workspace. Inbound messages route to the agent and every thread lands in your dashboard.
FEATURES
The app surface is wired to the same backend used by the webhook.
Live conversations
Search, export, reply, take over, and resolve threads stored in Supabase.
Knowledge base
Upload PDFs, text files, images, CSVs, HTML, JSON, or pasted text into R2-backed storage.
Test agent
Send sandbox messages through the same model key, prompt, and KB retrieval path.
Action controls
Toggle agent capabilities and approval requirements per workspace.
Line provisioning
Request an iMessage line from Sendblue during activation.
Workspace controls
Pause, resume, or delete a workspace through authenticated server calls.
PRICING
Billing is intentionally absent in this build.
The activation flow requests infrastructure and channel provisioning without collecting card data.
