PROOF FOR EVERY
SITUATION

Job Applicants
Cover letters and writing samples with proof attached. Show hiring managers you didn’t outsource your application to ChatGPT.
“I wrote this myself. Here’s the evidence.”
HOW IT WORKS
Write
Start typing in the editor. Every keystroke, deletion, and pause is recorded automatically in the background. No plugins, no account, no setup.
Copy
When you’re done, hit copy or use the button. Your text goes to clipboard with a unique proof link appended. The recording is saved and scored.
Prove
Share the link. Anyone can watch a real-time replay of your writing process — every hesitation, every correction, every burst of flow.
START WRITING
Your keystrokes are recorded locally as you type. Nothing is sent until you choose to save.
HOW THE HUMAN
SCORE WORKS
Every recording is analyzed across 9 independent behavioral metrics. The scores combine into a single 0–100 human-likeness rating, computed server-side from the raw keystroke data.
Score Tiers
No algorithm can definitively prove authorship. Dictation software, accessibility tools, and mobile keyboards may produce unusual patterns. These scores are indicators, not guarantees -the replay itself is always the strongest evidence. Read the full methodology →
INTEGRATE
PROOF
Embed human-authorship verification into your platform. Two endpoints, no SDK required.
- POST/api/recordings
- GET/api/recordings/{hash}
const res = await fetch(`https://justhuman.app/api/recordings/${hash}`);
const { analysis } = await res.json();
// analysis.score → 0-100
// analysis.confidence → "high" | "medium" | "low"
// analysis.metrics → per-signal breakdown
