How it works

From your samples to your first draft in four steps.

01
Samples

Upload Your Writing Samples

Drop in .txt, .md, .pdf, or .docx files — emails, Slack messages, long-form drafts, anything you’ve written. Samples are organized by channel and embedded for retrieval.
02
Interview

Take the Style Interview

Answer 10 short questions covering humor, punctuation, opinion strength, bad-news delivery, emoji usage, and more. Each answer maps directly to an adjustable style control.
03
Profile Build

Analyze & Fine-tune

Lane Brain builds your syntax map and vocabulary profile, then runs a fine-tune job. Review the detected profile and adjust any dimension before you start generating.
04
Streaming AI

Generate & Correct

Pick a channel, type a prompt, and watch the draft stream token by token. Mark anything off — corrections feed back into your profile for the next run.

Learns From Your Samples

Upload your real emails, messages, and posts. Lane Brain analyzes your vocabulary, sentence rhythm, and punctuation habits to build a profile unique to you.

10 Style Controls

Writing breath, humor level, cringe filter, opinion strength, punctuation, capitalization, signature slang, audience pivot, and bad-news delivery — all adjustable sliders.

4 Writing Channels

Text / IM, Internal Email, External Email, and Long-form — each channel has its own tuned profile so the tone fits the context automatically.

Real-time Streaming

Drafts appear token by token as they generate. No spinners, no waiting — you watch your writing take shape live.

Batch Generation

Queue multiple topics with per-topic channel selection. Generate a full content run in a single job and poll status until it completes.

Correction Learning

Mark phrases that aren’t quite you. Corrections update style weights and get embedded as new samples — so the next draft is closer to how you actually write.

Channels

Write for every context, automatically

You don't write the same way in Slack as you do in a proposal. Each channel gets its own tuned profile so the tone fits the context.

01💬

Text / IM

Casual

Short, punchy, and conversational. Your Slack and iMessage style — contractions, emoji, and all the personality that gets stripped from formal emails.

Casual toneEmoji-friendlyShort-form
02📧

Internal Email

Direct

Friendly but efficient. No corporate fluff. The way you actually write to teammates when no one's watching — direct, warm, action-focused.

External Email

Professional

Polished and persuasive. Your best professional tone — without sounding like a robot or a template. Confident, clear, and unmistakably you.

Structured

Detailed and well-organized. For blog posts, reports, and proposals that need depth, structure, and the authority of your own writing.

Frequently asked

Questions, answered

You upload your own text samples (.txt, .md, .pdf, or .docx) — emails, Slack messages, long-form drafts — and take a short 10-question style interview. Lane Brain analyzes vocabulary, sentence rhythm, and punctuation across 10 style dimensions to build your personal profile.

Four channels, each with its own tuned profile: Text / IM (casual, short-form), Internal Email (direct and collegial), External Email (polished and persuasive), and Long-form (structured reports, proposals, and blog posts).

Generic AI sounds like everyone. Lane Brain is grounded in your actual writing using retrieval-augmented generation and fine-tuning, then shaped by 10 explicit style controls — humor, formality, cringe filter, opinion strength, punctuation, capitalization, signature slang, audience pivot, bad-news delivery, and writing breath.

Yes. Every style dimension is an adjustable slider you can tweak per draft. You can also mark phrases that don’t sound like you — corrections update your profile weights and get embedded as new samples so the next draft is closer to your voice.

No. Lane Brain is entirely text-based. "Voice" here refers to writing voice — your unique style, tone, and vocabulary — not audio recordings.

Yes. Batch generation lets you queue multiple topics with per-topic channel selection and run them as a single job with status polling.

Your samples and generated drafts are used only to build and refine your personal profile. They are never used to train general-purpose models.

Your words, on tap.

Upload your samples, take the style interview, and start generating drafts that sound unmistakably like you — not a template.
