Your AI agent forgets every customer.
Sondex fixes that.
Sondex gives your AI agent a full relationship history for every person it talks to — past conversations, purchases, support tickets, and where things stand. One API call before each reply.
Customers
Every person who's emailed you, bought from you, or needed support. One profile, always current. Your agent never asks “can you remind me who you are?”
History
Full conversation thread, purchase records, and support timeline. Your agent never sends “thanks for reaching out!” to someone who's been a customer for six months.
Relationships
Who's waiting on a reply. Who just bought. Who's frustrated. Your agent reads the room instead of guessing.
Not just a database
Every conversation makes your agent smarter about that customer.
Sondex doesn't just store emails — it understands them. Every inbound message automatically updates the customer's profile: their sentiment shifts, their summary rewrites, their relationship status adjusts. By the time your agent queries the context API, the profile already reflects everything that's happened.
Auto-generated summaries
“Long-time customer, bought Pro in January. Had a billing issue last month (resolved). Currently evaluating the API tier.”
Relationship tracking
Status updates automatically — from “new lead” to “waiting on us” to “happy customer” — based on what's actually happening in the conversation.
Cross-source enrichment
Email history + Stripe purchases + support threads merge into one profile. Your agent sees the whole picture, not siloed data.
