Tegaki 手書き
A writing co-pilot. Not an automation tool.

“I don't know what to post.”
Yes you do. It happened this week.

Tegaki turns what actually happened in your week into a LinkedIn draft that sounds like you wrote it. You edit before anything gets published, and every edit teaches it more about how you write.

Tegaki never posts to LinkedIn. The publish button stays yours.

Why Tegaki

Showing up is the whole game. Sounding like yourself is the whole risk.

The people winning on LinkedIn aren't the best writers. They're the ones who post consistently, in a voice their network recognizes. Both halves matter, and each one kills the other: posting weekly is hard to sustain, and outsourcing it makes you sound like everyone else.

The silence tax Every quiet week costs you.

Deals, hires, and invitations go to the person your network thought of first. If you only post when inspiration strikes, you're invisible for the forty weeks a year it doesn't. Tegaki removes the blank page, which is the only reason most weeks go unposted.

The sameness trap Generic AI posts get read as spam.

Your network can smell a template. The moment a post opens with "In today's fast-paced world," trust drops and so does reach. Tegaki is built around one job: drafts that pass as yours, because they're built from your voice and your actual week.

The compounding asset It gets better every single week.

A ghostwriter starts over every month. A prompt forgets you tomorrow. Tegaki keeps a voice profile that learns from every edit you make, so the tool you have in month three is measurably better than the one you bought in week one.

How it helps you

Four moves. Minutes a week. Yours at the end.

Your week already contains the post. Tegaki's job is to find it, draft it in your register, and hand you something worth editing instead of a blank page.

1Teach it your voice

Paste a few of your past posts

Tegaki reads them and writes out an explicit voice profile: how you open, how long your sentences run, what you never say. You can read it and correct it.

2Tell it your week

Meeting notes, or just type

Paste notes from your notetaker or write freely about what happened. Thin material? It asks for more instead of making something up.

3Get a draft

Written, then challenged

Every draft goes through a second pass: a critic that hunts down every line that sounds generated and rewrites it in your register.

4Edit, and it learns

Your edits are the curriculum

When you change a line before publishing, Tegaki compares your version to its own and updates your voice profile with what it missed.

Your voice

Explicit rules, not vibes.

Most AI writing tools keep their idea of your voice inside a black box. Tegaki writes it down in plain English: concrete, checkable rules extracted from your real posts.

If it thinks you open with a blunt claim and close without a question, it says so, and you can correct it directly. A profile you can read and edit is worth more than an embedding you have to trust.

Every generation also carries two or three of your actual past posts along as examples. That does more for voice than any instruction.

Voice profile · Read and correct me
Opening move A blunt, specific claim. Never a rhetorical question.
Sentences Short. Mostly under 15 words. One long one per post, for contrast.
Paragraphs One to three lines, with air between them.
Closing A rule or a takeaway. Never "Agree?" or "What do you think?"
Never does Hashtag blocks. Emoji. Motivational endings.
Returns to Sales process, hiring mistakes, lessons from lost deals.
Our principles

Three things Tegaki refuses to do.

Every other tool in this category leads with automated posting and impression graphs. These refusals are the product, and they're why you can trust what goes out under your name.

Won't post for you No publishing. No scheduling.

Tegaki has no LinkedIn integration at all. Nothing goes out under your name until you have read it, edited it, and posted it yourself. The product says this out loud.

Won't invent Facts come from your week, or not at all.

The generator may only use what you gave it. If the material is thin, it tells you and asks for more. A fabricated anecdote published under your name is the worst failure this product can imagine.

Won't sound like AI Banned patterns, enforced.

A hard blocklist of the phrases that give AI writing away, checked after every generation. A draft that trips the check gets rewritten before you ever see it.

Also banned unless your own past posts do it: hashtag blocks, emoji, and closing with "What do you think?"

The learning loop

Your edits are the product.

Save an edited draft and Tegaki studies the difference between what it wrote and what you kept. What it learns goes into your voice profile, with a full version history you can audit and roll back.

The voice match figure is computed from something real: how much of each draft you leave untouched, measured across your recent edits. When it goes up, that means you are editing less because the drafts need less.

Who we are

Built by people who hated posting too.

A note from the founders

Tegaki started with a sentence we kept hearing from smart, busy people, and kept saying ourselves: "I know I should post more, I just don't know what to say."

The truth was never a lack of material. Every week had a lost deal, a hiring lesson, a small win worth telling. What was missing was the bridge between a real week and a publishable post, and every tool we tried crossed that bridge by sounding like a robot or by posting on our behalf. Both felt like handing our reputation to someone else.

So we built the tool we wanted: one that starts from what actually happened, drafts in a voice it learned from our own writing, refuses to invent, and hands the final word back to us. Every time. We use it for our own posts, every week, and it gets a little more like us each time we edit.

If that's the relationship you want with your own voice, we built this for you.

手書き · "Handwritten"

The name is the promise.

Tegaki is Japanese for handwriting. What goes out under your name should read like it came from your hand. This is the tool for that.
