Language models for enterprise applications.
Businesses and developers need real-time language quality checks (grammar, AI-generated text detection, autocomplete) built into their workspaces and messaging tools, but building this in-house is hard.
Sapling provides an API/SDK plus browser extension and MCP server delivering grammar, AI detection, autocomplete, rephrasing, and chat assist as drop-in components or a single HTTP request.
The page claims its grammar checker catches 60% more language quality issues than other checkers, and offers enterprise-grade security (private cloud, AES-256 encryption, PII redaction, SSO/SCIM/MFA) plus a dedicated MCP server for AI assistants.
Founded in 2019 by Ziang Xie as a Y Combinator-backed company; it later partnered with contact-center firm ibex to power AI messaging tools.
