Proofreading in notes

This article covers what gets checked, how the marks behave while you type, how to accept or dismiss a fix, and where the switch lives.

What gets checked

Four things.

• Spelling. Words that aren't real words as written: typos, swapped letters, missing letters. Shown with a red underline.
• Grammar. Mixed-up words like their/there/they're and its/it's, missing apostrophes, missing hyphens in phrases like "long-term plan", doubled words ("the the"), a sentence that starts lowercase, a day or month that isn't capitalized, a missing period at the end of a paragraph, the wrong preposition ("observant to" instead of "observant of"), "myself" where "me" belongs, a list that breaks its own pattern ("invest in ads or paying creators"), and a stray comma. Shown with a blue underline.
• Wordy phrases. Filler words and stock phrases that have a shorter exact equivalent: "be able to" for "can", "in order to" for "to", "going to" for "will", and fillers like "just" and "really" when they add nothing. The fix is always a swap or deletion of a few words; the rest of the sentence is never touched. Shown with a purple underline.
• Heavy sentences. Sentences a reader would have to read twice: long stacked clauses, a buried subject, chains of "of the", heavy passive voice. Shown as a small amber dot at the end of the sentence, never an underline. See "Heavy sentences" below.

Eden does not rewrite your sentences for style, tone, or voice. If a sentence is correct and reads cleanly, nothing is marked. Proper nouns, product names, handles, links, and code are left alone.

How it behaves while you write

Eden checks one sentence at a time, and only sentences that changed.

• The sentence you're typing is left alone until you close it with a period, question mark, or exclamation point. A half-typed thought is never flagged.
• Finished sentences are checked about a second after you pause. Underlines usually appear within a second or two after that.
• Untouched sentences are never re-checked. Fixing one word in a long note only re-checks that sentence.
• Underlines follow your text. Typing above or around an underline moves it with the word. Editing the underlined word itself clears it, and the sentence is checked again once you pause.

Accepting or dismissing a fix

Hover any underline to open a small card that shows the original word and the suggested fix.

• Accept replaces the word in place. It's a normal edit, so Undo (Cmd+Z or Ctrl+Z) reverses it.
• Dismiss hides the underline for that sentence. Eden won't bring it back unless you edit the sentence again.
• Click an underline instead of hovering to pin the card open, which is handy on a trackpad.

Turning it off

Three ways, from narrow to wide.

• For one note: open the note's ⋯ menu (top right) and switch off Proofread. Only that note stops being checked (underlines and dots), on every board it appears on. Switch it back on from the same menu.
• One kind of check, everywhere: open Settings → Preferences → Editor. Under Proofread there are separate switches for Spelling, Grammar, Wordy phrases, and Heavy sentences. Turn off the one you don't want; the others keep running. Changing a switch re-checks the open note right away.
• Everything, everywhere: switch off Proofread itself in the same place. The per-check and per-note switches disappear while it's off. Turn it back on any time; Eden checks the open note again right away.

Heavy sentences

Alongside the underlines, Eden keeps an eye on flow.

• When you open a note, Eden reads it once and puts a small amber dot at the end of the few sentences a tired reader would have to read twice. About five per screen at most, one per paragraph, and none if the note reads cleanly.
• As you write, a paragraph you finished gets a quiet second look a couple of seconds after you pause. Only a clearly heavy sentence earns a new dot between full passes, and the per-screen cap always holds.
• Hover a dot to see why the sentence is heavy. Click Rephrase to get two or three rewrites from Eden's stronger writing model. Pick one to swap it in, or Dismiss the dot. A dismissed sentence stays dismissed.
• Editing a marked sentence clears its dot.

Eden never rewrites anything on its own here. It only looks at structure, not tone or word choice.

Where it works

Notes opened in a pane, in the side peek, and in full-screen focus mode. Only workspace members get proofreading. Public pages and shared-link views are never checked, even when the link allows editing. Headings, quotes, list items, task items, and toggle headings are checked along with paragraphs. Text inside tables and code blocks is skipped.

Notes on accuracy

The checker is an AI proofreader, not a dictionary. That is why it can handle any language and understands context (it knows "their" is wrong in "their going to be late"). It can still miss a mistake or, rarely, flag something that's fine. Dismiss anything you disagree with; nothing changes in your note until you accept a fix.
