Voice Intelligence Engine

Your voice.
Every AI.

Paste 150–600 words of your real writing. VoiceEngine performs a forensic 16-dimension analysis and builds a deployable voice profile — a machine JSON file any AI tool obeys, plus instructions written for humans. AI that finally sounds like you, not like AI.

How it works

From writing sample to voice blueprint in four steps

No training runs and no sample storage. Every provider call crosses an authenticated, entitlement-gated HTTPS gateway; samples are forwarded transiently and provider credentials remain server-side.

STEP 01

Paste your writing

An email, a post, a chapter — anything you actually wrote. 150–600 words is the sweet spot.

STEP 02

Get decoded

The engine dissects tone, rhythm, structure, vocabulary, and risk posture across 16 dimensions — with scores you can inspect and correct.

STEP 03

Set the rules

Pick intent, audience, and content type. Flip on hard filters like NO HYPE, NO HEDGING, NO AI TELLS — enforced, not suggested.

STEP 04

Deploy anywhere

Copy the machine file into ChatGPT, Claude, or any AI tool as a system prompt. Keep the human doc for your team.

Features

Built like an instrument,
not a toy

Every output is validated, retried on failure, and quality-scored before you ship it.

◈

Forensic 16-dimension analysis

Energy, formality, directness, specificity, confidence — plus signature moves, phrasing habits, and what you never say. Rendered as animated score bars you can audit and override before anything is generated.

ENFORCED
⛔

12 hard style filters

NO HYPE, NO HEDGING, NO PADDING, NO AI TELLS and 8 more — written into the profile as rules, not vibes.

⇄

Machine + human outputs

A strict JSON system prompt for AI tools, and a readable instruction doc for people. Always in sync, both exportable.

◎

AI quality check

A second AI pass scores the profile on 5 dimensions and warns you below 70 — before you rely on it.

☁

Profiles that follow you

Save voice profiles to your account and reload them on any device. Private exports can also stay on your device.

SERVER-SECURED
⚿

Credentials stay off the client.

Works with Anthropic, OpenAI, and DeepSeek through a server-owned gateway. Provider credentials never enter browser storage, network payloads, or shipped source.

✆

Mobile-first

Every step, modal, and export works on a phone. Guided tour included — clear enough for an 8-year-old or an 80-year-old.

Privacy by design

We don't store your writing.
That's the architecture.

Pricing

Costs less than the words it saves you

FAQ

Fair questions, straight answers

Do I need my own AI account?
No. VoiceEngine securely routes requests through server-managed Anthropic, OpenAI, or DeepSeek credentials.
Which AI tools can use my voice profile?
Any tool that accepts a system prompt or custom instructions: ChatGPT, Claude, Gemini, Copilot, API integrations, agents — the machine file is plain JSON with an embedded system prompt.
Is my writing stored anywhere?
No sample is stored by BNDR. Requests cross the encrypted gateway only long enough to enforce access and forward the call. We store only account data, usage counts, reports you submit, and finished profiles you explicitly save.
Can I cancel my subscription?
Yes. Manage Billing opens a secure Stripe customer-portal session from your account menu. Access continues through the paid period unless a refund or chargeback revokes it.
How does the lifetime license work?
When Gumroad purchasing is enabled, you buy once and receive a license key. Redeem it while signed in to unlock the lifetime entitlement. Existing codes can be entered now.
Does it work on my phone?
Yes — the whole flow is mobile-first: analysis, filters, exports, saving, and the guided tour all work on any modern phone browser.
