Grammarly is a general-purpose writing assistant. Sapling catches more errors on real business messages and adds snippets, autocomplete, rephrasing, and suggested replies inside the CRM and help desk your team already uses, with an API, multiple languages, and self-hosting when you need them.
No credit card required. Or try the free paraphrase tool without an account.
Grammarly is the most widely used writing assistant. It checks spelling, grammar, punctuation, and clarity across many apps, predicts tone, and includes a plagiarism checker and a web editor. Grammarly Business adds style guides, snippets, and an analytics dashboard for larger accounts.
Sapling is an AI writing assistant for customer-facing teams. Its grammar checker runs on neural language models rather than hand-written rules, and it adds rephrasing, snippet macros, autocomplete, suggested chat responses, and quality scoring inside Salesforce, Zendesk, Intercom, Gmail, Outlook, and hundreds of other web apps.
Sapling's neural grammar checker catches 60% more errors than leading competitors on a third-party dataset, especially the missing words and mangled phrasing common in fast support replies.
Autocomplete and suggested chat responses help agents reply faster in live chat and tickets. Grammarly corrects what you type; it does not help you write the reply.
Sapling runs in Salesforce, Zendesk, ServiceNow, Intercom, Gmail, and Outlook, with snippet macros and quality scoring where agents actually work.
Sapling checks grammar in multiple languages and can train custom models on your own data. Grammarly currently supports English only.
SOC 2 Type II, HIPAA with BAA coverage, zero data retention options, and self-hosted or on-premises deployment for regulated teams.
Add grammar checking, rephrasing, tone detection, and AI content detection to your own product with the Sapling API and SDK. Grammarly does not offer direct API access.
