What you can do

Sapling works in the app you are already writing in. Each feature has its own switch in the Sapling menu bar menu.

  • A suggested correction shown under an underlined word, with Accept and Ignore

    Fix mistakes as you write

    Spelling and grammar issues are underlined. Hover over an underline and click the suggestion to apply it. Control+O accepts every suggestion at once; Control+I accepts those in the current sentence.

  • A grey suggested word after the text being typed, with a Tab hint

    Finish sentences with Tab

    As you type at the end of a line, Sapling suggests what comes next in light text. Press Tab to accept it, or keep typing to ignore it. Available on paid plans.

  • A list of saved snippets under the caret, each with its shortcut

    Insert saved replies

    Type a snippet's shortcut and it expands in place. Type \ to search your snippets where you are writing, or press Control+L for a search box.

  • A panel of rewrites for a selected sentence, with options such as Formal, Shorten and Friendly

    Rephrase a selection

    Select text and press Control+J to see rewrites: paraphrase, formal, shorter, longer, or a different tone. Press Enter to replace your selection.

On paid plans, Sapling also shows the tone of what you are writing in the corner of the window.
