DetailsBuilt for text web chat
SiteTrellis does one job, and these are the edges of it.
- Text, not voice. Replies arrive whole rather than token by token.
- Knowledge you write. Paste what the agent should know; there is no website crawler, file ingestion or embeddings search.
- Your website is the channel. Email is outbound only; there is no inbound email, WhatsApp or Slack.
- Webhooks and custom tools instead of native CRM connectors, a prompt and rules instead of a flow builder, and email sign-in instead of SSO.
Products
Every product shares your account, team and billing.
