Sapling
Sapling offers grammar correction, autocomplete, paraphrase and AI-detection via browser extensions, a REST API, SDKs and an enterprise MCP server. It checks text, returns suggestions and detector results, and exposes endpoints for integrating writing assistance into web apps and messaging platforms, with per-check detector limits documented on product pages.
Public pages list a Free tier ($0/month), a Pro tier ($25/month) with an annual variant shown, an Enterprise tier with a documented seat minimum, and a metered API plan with a one-time $5 minimum.Is Sapling right for you?
Good for
- Founders embedding writing assistance and AI-detection into web apps or messaging platforms via REST APIs or browser extensions.
- Multiple surfaces: REST API, SDK components, browser extension, and MCP server to integrate suggestions where teams work.
- High per-check detector capacity on paid plans — Pro and Enterprise document per-check character limits up to 100,000 characters.
Keep in mind
- Enterprise purchasing requires contacting sales and the site does not publish full contract pricing or security documentation inline.
- Team plans have a documented minimum seat requirement that may increase initial costs for small teams.
- Confirm enterprise contract and detector billing terms before committing to large-volume use, because full enterprise pricing and security docs require contacting sales and are not fully published on the linked official pages.
Pricing and plan limits
The site shows a Pro monthly price ($25/month) and an 'Annual ($12 / mon)' figure without explicit billed-annually language; the pages also require contacting sales for full Enterprise quotes. The linked official pages do not list complete contract or enterprise pricing details.
