Writing Craft
Arc Editor
A real-time co-writing canvas with inline AI marginalia — coaching in the margins while you draft.
The Arc Editor brings the Write to the Top methodology into the moment of composition. It is a clean, two-pane writing canvas: your draft on the left, living marginalia on the right. As you finish a paragraph, ask for analysis and the margin fills with the notes a master teacher would leave — on claim strength, transition quality, sentence variety, and opportunities to deploy a GWA Power Word.
Every note is typed and targeted: a thesis note, a structure note, a style note keyed to a specific Style Axiom. Strengths are named alongside suggestions, and each paragraph receives a coaching score so you can feel a draft tightening in real time. A subtle writing-streak indicator keeps you honest about momentum without gamifying the craft.
It is the difference between getting feedback on your essay and getting feedback inside it — revision and drafting collapsed into a single, focused flow.
