Write the next chapter

Hermes is AI writing software for novelists. It continues scenes, suggests the next words, rewrites passages, and talks through plot problems, guided by your story and your style. Its rewrites wait on the page until you keep them.

2,500 AI words a month are free. No card needed.

Hermes suggested the end of this headline. Keep it?

Scroll, and the scene writes itself.

The harborHermes

The harbor

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.

Hermes waits until you askTell Hermes what to write or change…
Step 1 of 7Your draft

Your draft

Start with your own words.

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

Hermes picks up the thread.

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

Try another way to say it.

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

Make a focused edit.

Select a phrase, choose Edit, and say what to change. The edit lands in place, and undo brings back your original.

Autocomplete

Find the next few words.

With Hermes on Suggest, a suggestion waits at your cursor when you pause. Tab keeps it and Esc dismisses it.

Chat

Talk through what happens next.

Open the conversation beside your chapter. When an idea fits, Hermes writes it straight into the scene, and undo takes it back.

Your chapter

Hermes wrote in pencil. You chose the ink.

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.

Now try it with your own writing.

Paste a passage and let Shared Pen continue it, with no account or card. Or step through the other tools in a sample scene.

Hermes keeps a style sheet for every book.

Copyeditors keep one so page 300 reads like page 1. Hermes notes how you write, then follows the point of view, tense, and tone you set.

Questions writers ask

What is Hermes?

Hermes is an AI writing workspace for novelists and storytellers. It combines project organization with Shared Pen co-writing, autocomplete, rewrites, AI chat, and writing style guidance.

Is there a free plan?

Yes. Every account includes 2,500 AI words per month, and you don't need a payment method to start. Words you type yourself never count. When you want more, upgrade to Pro; billing starts at checkout. You can cancel anytime through Manage billing in account settings.

Are AI words unlimited?

No. Pro has a standard 250,000-word monthly allowance. AI usage is estimated from token counts; it is separate from words you type yourself. Account overrides and purchased credits can change your available allowance. Pro users can purchase an additional 50,000 words for $5 USD. Check your account usage for your current balance.

How is my writing processed by AI?

Using AI features sends content to third-party AI providers through OpenRouter, as described in the Hermes privacy policy. Providers have their own data-handling practices. Review the policy and linked provider policies before submitting sensitive material.
