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.
From your notes to your voice — in three steps.
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.
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.
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.
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.
