Why Iliad

Good writing means reading every sentence

When an AI writes the draft for you, you get fluent text that says little and doesn’t sound like you. In Iliad you do the writing. AI helps with the next sentence, a shorter paragraph or a round of edits from Claude, and you read each change before you keep it.

The editor

A quiet page for long writing

Iliad hides the Markdown syntax on every line except the one you are editing. Drag in an image and Iliad saves it in an assets folder next to your document. Write LaTeX between $$ and it shows as a formula. The file on disk stays plain Markdown.

Images

Drag or paste a picture. Iliad copies it into assets/ and links it from the file.

Math

Inline $x^2$ or a $$ block. You see the formula, the file keeps the LaTeX.

Typography

Serif, sans or mono at the size you like. The setting stays in the app, out of your files.

Writing, assisted

AI at your cursor

Press ⌘, for a sentence, ⌘. for a paragraph or ⌘/ for the whole idea. A fast model on Groq writes the suggestion and follows the writing preferences you set, such as “short sentences, no adverbs”. The AI is free with a daily limit, or you can use your own Groq key.

Command comma asks for a sentence, Command period for a paragraph, Command slash for the full idea.

Inline completion

One key for each size of help. Tab accepts, Esc dismisses.

✦ AI on a selection

Select text, press ⌘↵ and pick Rewrite, Expand, Shorten, Summarize or Turn into a list. The result appears next to your text until you accept or reject it.

Bring your own agent

Works with your agent

Leave comments on the passages you want changed, then ask Claude Code or Codex to address them. Iliad shows each change in the page, and you keep it or restore your version.

A Claude Code session in a terminal. Asked to address the comments in the open document, the agent loads the Iliad skill, runs iliad status, reads drafts/the-lighthouse.comments.md, edits drafts/the-lighthouse.md, removes the two addressed comments and runs iliad open to show the first change. Iliad then shows both changes for review.

Your agent downloads Iliad and installs the iliad command and the skill.

Who it’s for

Writers who sign their work

  • Novelists

    Draft chapters in one folder. When a scene stalls, ask for one sentence, then keep it or write your own.

  • Journalists

    Shorten a piece to length and check each cut before you file.

  • Playwrights and screenwriters

    Write scenes as plain text. Ask for a line of dialogue only when you are stuck.

  • Academics

    Write equations in LaTeX, add figures and review every edit an agent makes to a chapter.

  • Students

    Write your own essay. If an agent edits it, you see each change and decide what stays.

  • Bloggers

    Your posts are Markdown files, ready for any static site or CMS.
