Wordtune rewrites one sentence at a time. Sapling rephrases, fixes grammar, fills in snippets, autocompletes, and suggests replies — inside the CRM and help desk your team already uses, with enterprise security behind it.
No credit card required. Or try the free paraphrase tool without an account.
Wordtune, from AI21 Labs, is a general-purpose AI writing companion. It suggests alternative phrasings for a sentence, shifts between casual and formal tone, shortens or expands text, and summarizes documents. It is a good fit for individuals polishing essays, emails, and documents.
Sapling is an AI writing assistant for teams. It rewrites and adjusts tone like Wordtune, but it also catches grammar and spelling mistakes, inserts reusable snippets, autocompletes as you type, and suggests full replies in chat — all inside Salesforce, Zendesk, Intercom, Gmail, Outlook, and hundreds of other web apps.
Sapling pairs sentence rephrasing with a grammar checker that catches 60% more errors than leading competitors, so you do not need a second extension for corrections.
Snippet macros, autocomplete, and suggested chat responses cut the time agents spend retyping the same answers — features Wordtune does not offer.
Sapling runs in Salesforce, Zendesk, ServiceNow, Intercom, Gmail, and Outlook, not just in a separate editor or Chrome tab.
SOC 2 Type II, HIPAA with BAA coverage, zero data retention options, and self-hosted deployment for regulated teams.
Managers see usage, errors, and quality trends across the whole team instead of reviewing a handful of messages by hand.
Bring rephrase, grammar checking, and tone detection into your own product with the Sapling API and JavaScript SDK.
