What is Sapling?
Sapling is an AI language platform that adds grammar checking, autocomplete, rephrasing and text snippets to the tools customer-facing teams already use. It also includes a popular AI content detector. The product is aimed at support, sales and operations teams, plus developers who want to build language features into their own apps. Sapling is backed by Y Combinator.
Sapling works through a browser extension, an API and SDK, and an MCP server that AI assistants can call. It connects to Zendesk, Salesforce, ServiceNow, Gmail, LinkedIn and contact center tools like Amazon Connect and Twilio Flex. Enterprise customers get SSO, SCIM, PII redaction and optional self-hosting, which matter in regulated industries.
