For founders, execs & creators

Everything you publish,
in your own voice.

Idiolect turns your rough notes into posts, threads, and emails that read like you wrote them — then scores every draft on a validated voice‑fidelity metric. So “sounds like me” is something you can measure, not just hope for.

  • Your writing stays yours
  • Honest scores — never “indistinguishable”
  • Works with ChatGPT, Claude & your tools

most “thought leadership” is just the same five takes on repeat. here’s the one thing shipping this week actually taught me: your roadmap is a hypothesis, not a promise. cut the feature nobody asked for. tell people why. they respect the cut more than the ship.

How it works

From your notes to your voice — in three steps.

1

Capture your voice

Paste a few things you’ve really written — posts, emails, messages. Idiolect builds your Voice Profile: how you write, and the takes you actually hold.

2

Write anything

Give your take in a sentence. Get a LinkedIn post, an X thread, a newsletter — generated several ways, in your voice, with the best one chosen for you.

3

Proof it’s you

Every draft is scored on the validated metric and shown against generic AI. You ship knowing it reads like you — measured, not guessed.

The metric

We can prove it sounds like you.

Everyone says “we learn your voice.” We’re the ones who can show it. Voice Match scores a draft against your own writing on an independent, validated authorship model — so the claim is a number, not a vibe.

  • Relative, not forensic — we measure “closer to you,” we never claim “indistinguishable.”
  • Out-of-sample by design — the score isn’t the one the engine optimized against.
  • Lead with the lift — every draft shown as points gained over generic AI.
