In their own words
Sapling
Sapling combines writing assistance for teams with developer tools for adding language model-powered features to applications. Its writing tools include grammar and spelling corrections, autocomplete, rephrasing, tone and sentiment checks, and AI content detection. Style suggestions and tone detection are available, with support for 14 languages. Developers can access HTTP API endpoints and SDK components, including Python and JavaScript client libraries. Sapling lists 73 integration guides, with examples for Zendesk, Salesforce, Slack, Google Docs, Microsoft Word and browser extensions. It is available on the web, through extensions and Windows, via API, and in self-hosted deployments. Sapling says it uses TLS encryption in transit and AES-256 encryption at rest, and describes GDPR compliance and SOC 2 Type II certification. Enterprise accounts include audit logs, role-based access and single sign-on. The free plan has AI detector limits; paid writing assistance starts at $12/user/mo billed annually, and a 30-day trial is listed. API trials have a character limit and expire after one month.
StealthWriter
StealthWriter rewrites AI-generated or AI-assisted text to improve phrasing, flow, and clarity, and includes an AI detector. Its humanizer provides light, medium, and aggressive rewrite levels. The detector estimates whether submitted text may be flagged as AI-generated and gives overall and sentence-level feedback. It accepts text from tools such as ChatGPT, Claude, Gemini, Llama, Mistral, Copilot, and Jasper; listed supported languages include Spanish, French, German, Italian, Portuguese, and Dutch. StealthWriter runs in modern browsers on desktop, tablet, and mobile, with Android, iOS, and web listed as platforms. The free plan allows 10 humanizations and 10 AI scans daily, up to 1,000 words per input, and includes Ghost 5.2 Mini. Paid plans start at $20 a month and allow up to 5,000 words per input, with Ghost 5.2 Pro and Ghost Legacy also included. The public detector demo has a 500-word scan limit and daily limits. The maker advises reviewing rewritten text because a rewrite can alter details or how a claim is expressed.
