Decode

Entropik Technologies

Freemium

A human insights platform that uses emotion AI, webcam eye tracking, and predictive models to test creative, products, and experiences before launch.

Emotion AI Measurement: Face emotion, voice emotion, and text sentiment analysis reveal how respondents actually feel during a study rather than only what they report in an answer.
Webcam Eye Gaze Tracking: Real eye tracking runs through a participant's own webcam with zero hardware, producing attention heatmaps that show where people look first and what they miss.
AI Creative Insights: Neuro AI predicts attention, emotional resonance, brand recall, and conversion impact for ad creative, packaging, OOH, and web layouts before media spend is committed.
Synthetic Audience: Build reusable synthetic personas and compare how each creative performs persona by persona ahead of fielding a study with real respondents.
AI Moderator: Runs moderated and unmoderated interviews at scale, then extracts themes, emotions, and supporting evidence from raw interview and video feedback automatically.
Shopper and Shelf Simulation: Simulates real-world shelf and pack testing with attention heatmaps, shelf visibility analysis, planogram optimization, and purchase-intent prediction.
UX Research Suite: Prototype testing, unmoderated task studies, usability and wireframe testing, card and tree sorting, and live website and app testing, each enriched with gaze and emotion data.
Global Respondent Panel: Access to more than 103 million respondents worldwide, or bring your own panel free of charge on any plan.

Pre-Flight Ad Testing: Comparing creative variations and messaging options to predict which version earns attention and recall before buying media.
Packaging and Shelf Decisions: Testing pack designs and planograms in a simulated retail environment to forecast visibility and purchase intent.
Product Concept Validation: Screening product concepts, storyboards, and innovation ideas for early-stage market fit before committing development resources.
UX Friction Discovery: Running prototype and usability studies where webcam eye tracking and emotion signals expose confusion users cannot articulate.
Qualitative Research at Scale: Using the AI Moderator to conduct and synthesize many interviews into structured themes instead of manual transcript coding.
Brand Tracking and Price Testing: Running recurring consumer studies on brand perception, pricing, and the customer journey across multiple markets.

An open agent skill that rewrites AI-sounding text to read like a person wrote it, without changing what the text actually says.

25 Named Patterns: A ranked catalogue of AI-writing tells — from 'not X but Y' staging to decorative bold, chatbot residue, and knowledge-limit disclaimers — each with before and after examples.
Strength-Weighted Detection: The first five patterns justify an edit on a single sighting, while patterns marked weak alone only count when several share a passage, so deliberate stylistic choices survive.
Draft-Critique-Final Loop: Humanizer shows its work by producing a first rewrite, a short critique of whatever still sounds artificial, and then the final version.
No Invention Guarantee: Names, numbers, dates, quotes, and citations must come from the source or the writer; if a sentence needs a missing detail the skill asks rather than fabricating one.
Voice Matching: Supply a writing sample and the rewrite follows its rhythm, word choice, punctuation, and deliberate quirks, including em dashes if you use them.
File-Safe Rewriting: Point it at a file path and it edits prose only, leaving code, data, frontmatter, and link targets untouched.
Agent-Agnostic Install: Distributed as Markdown so it works with any skill-capable agent, via the Skills CLI, the Claude Code plugin, or a ZIP upload in Claude Desktop.
Register-Aware Output: Personal writing keeps the writer's opinions and quirks while technical and reference prose stays neutral and plain.

Cleaning Up AI Drafts: Run a model-generated blog post or essay through Humanizer before publishing so it does not read as machine-written.
Matching a House Voice: Provide a sample of existing published work so rewritten copy matches an established author or brand voice.
Documentation Editing: Point the skill at a repository file to strip decorative headings and staged sentences from technical docs without touching code blocks.
Email and Outreach Polish: Remove sales language and borrowed authority from outbound copy so claims are stated plainly.
Editorial Review: Use the marked list of tells as a critique pass to teach writers which habits read as AI-generated.
Agent Pipeline Step: Chain Humanizer after a drafting agent so generated text is normalized before a human ever reviews it.
