LarkWrite is built for writers who are tired of AI that sounds like AI โ€” and tired of tools that ghostwrite their book.

THE DEFAULT IS COACHING, NOT GENERATION While you pause, LarkWrite leaves reader's notes in the margin: questions about what a scene is withholding, what the reader needs to feel, or what memory you might be glossing over. Nothing is inserted into your draft unless you ask.

EXPLORE WHEN YOU'RE STUCK Answer a margin note in a coaching chat. The AI asks follow-ups and suggests angles โ€” like a workshop partner who won't write the scene for you.

YOUR VOICE, ENFORCED Paste or upload samples of your past writing (Substack, Medium, DOCX, or plain text). LarkWrite builds a voice profile so suggestions fit how you actually write. Editable writing rules apply to every AI output โ€” by default they ban hedging, clichรฉs, essay cadence, and inflated significance.

REVISION ON YOUR TERMS Select text when you want help. Revise tightens language; Reframe offers a different angle. AI-inserted words stay highlighted. You earn writing points for words you type yourself.

ANY GENRE Describe your project in your own words โ€” memoir, slam poetry, lyric essay, romantasy, flash fiction โ€” and the coach adapts.

PRICING โ€ข Free โ€” 3 projects, 1 writing sample, 30 reader's notes/month โ€ข Plus โ€” $10/mo โ€” 10 projects, 5 samples, 150 notes/month, Reframe, Word export โ€ข Pro โ€” $20/mo โ€” unlimited projects & AI assistance, 20 samples, PDF/EPUB export

PRIVACY Projects live under your account only. Writing is sent to the AI provider solely to generate your feedback โ€” not shared with other users or used for model training.

Questions & Answers

As answered by people managing OpenAI and LarkWrite.

Who are some of the biggest customers of your product?

LarkWrite's answer:

Individual authors and early adopters โ€” no enterprise customers yet.

What makes your product unique?

LarkWrite's answer:

LarkWrite is built around coaching, not generation. The default interaction is reader's notes in the margin โ€” questions about scene, voice, and structure โ€” not paragraphs pasted into your draft. It learns your voice from your own writing samples, enforces mandatory anti-AI-tell rules on every output, and highlights any AI-suggested text so you stay visibly the author. It also works for any genre you describe (memoir, poetry, essays, fiction) rather than forcing one template.

Why should a person choose your product over its competitors?

LarkWrite's answer:

Choose LarkWrite if you want a writing coach, not a ghostwriter. Compared to ChatGPT or general AI assistants, LarkWrite is designed for long-form creative work: projects, outline, export, and margin feedback anchored to your text. Compared to tools like Sudowrite or Jasper, it doesn't optimize for speed-writing finished prose โ€” it optimizes for keeping your voice and your ownership of the draft. You get voice profiling, editable writing rules, Explore coaching chats, and optional Revise/Reframe only when you select text. Free tier lets you try it without a credit card.

How would you describe the primary audience of your product?

LarkWrite's answer:

Independent writers working on creative long-form projects: memoirists, personal essayists, poets, songwriters, and fiction authors (including NaNoWriMo drafters). Also writers who publish on Substack or Medium and want revision help that doesn't flatten their voice into generic AI prose. The product is for people who want feedback and ideas but refuse to outsource authorship.

What's the story behind your product?

LarkWrite's answer:

LarkWrite started from a simple frustration: general AI tools are good at handing you paragraphs, but bad at helping you sound like yourself on work that matters. Most "AI writing" products push generation; LarkWrite was built the other way around โ€” a thoughtful reader in the margin first, conversation second, text suggestions only when you ask. The name and logo (a lark on a pen nib) reflect that idea: amplification of your voice, not replacement of it.

Which are the primary technologies used for building your product?

LarkWrite's answer:

Next.js (React) โ€” web app and API routes TypeScript โ€” application code Anthropic Claude โ€” AI coaching and feedback Stripe โ€” subscriptions and billing Tailwind CSS โ€” UI
