Hermes suggested the end of this headline. Keep it?
A prewritten session in the Hermes editor, one tool at a time. Nothing here is sent to an AI provider.
The harbor stretched below, its water flat as poured lead. Mara leaned on the railing. For the first time in years, she had come back without a reason to leave.
She was nervous when she saw the old boat coming toward her.
She walked to the end of the pier with a feeling of uncertainty about what might happen next.
but she could still read it.
Your draft
Hermes reads your chapter, your notes, and your style sheet before it suggests anything. Keep scrolling to write the rest of the scene.
Shared Pen
Switch Hermes to Co-write and give it a direction. It writes the next paragraph right on the page. The new words glow for a moment, then become part of your draft while Hermes keeps going.
Rewrite
Select a sentence and choose Rewrite. The new version shimmers in where your sentence was. Flip through versions, then keep one or revert.
Inline edit
Select a phrase, choose Edit, and say what to change. The edit lands in place, and undo brings back your original.
Autocomplete
With Hermes on Suggest, a suggestion waits at your cursor when you pause. Tab keeps it and Esc dismisses it.
Chat
Open the conversation beside your chapter. When an idea fits, Hermes writes it straight into the scene, and undo takes it back.
Your chapter
Rewrites waited for your choice, and everything Shared Pen wrote was one undo away. In your own projects, you can pause, steer, undo, or ignore Hermes at any point.
Paste a passage and let Shared Pen continue it, with no account or card. Or step through the other tools in a sample scene.
