Records with Critical Errors
Annual Cost of Bad Data per Organisation
Human Errors Quietly Undermine Every Dataset
Spreadsheets, CRM entries, ERP systems, even board reports — the key information businesses rely on is riddled with mistakes. And as AI adoption accelerates, the cost of bad data compounds exponentially.
Teams enter data every day, but errors are inevitable: wrong currencies, illogical dates, duplicate records, inconsistent names, missing fields. These errors corrupt your analysis, forecasting, and AI models — costing time, money, and trust.
— Gartner Group, 2025
The 1–10–100 Rule of Data Quality
Every error that escapes downstream from entry multiplies in cost. DataCheckr keeps you at 1× — all the time.

VQD Models — Purpose-Built for Data Precision
Large Language Models hallucinate on numbers and dates. DataCheckr’s Vector Quality Definition (VQD) models are precision-engineered for data integrity.
| Capability | LLM (ChatGPT) | DataCheckr VQD |
|---|---|---|
| Numeric accuracy | ✗ Hallucinates | ✓ Precise |
| Date validation | ✗ Unreliable | ✓ Exact |
| Works offline / local | ✗ Cloud only | ✓ Edge processing |
| Learns from user feedback | ~ Limited | ✓ RLHF built-in |
| Data stays private | ✗ Sent to cloud | ✓ Never leaves device |
| Speed per check | Seconds | ✓ Milliseconds |
| Setup time | Extensive configuration | ✓ Under 1 hour |
| Zero-shot on any dataset | ✗ Requires training data | ✓ Day 1 ready |
The HEAT Engine
At the heart of DataCheckr AI is our Human Error AI-powered Trapping (HEAT) engine — catching mistakes at the exact moment they happen.
Precision Checking Models
VQD data integrity model that continuously improves leveraging zero-shot and reinforcement learning.
Real-Time Flagging
Flags suspicious values the instant they’re entered with ternary classification: Good / Probably Bad / Definitely Bad — directing attention to critical issues first.
Reinforcement Learning
Learns from every user interaction to deliver more personalised and accurate error checking with each use. RLHF built-in — no manual effort required.
Team Oversight
Provides individual and team-level visibility. Share tuned models via the cloud model library — everyone benefits from your learning immediately.
Edge Processing
For privacy and performance. Analysis of your data stays local and lightning fast – no cloud uploads.
Patterns, Not Values
We do not store or reuse your underlying data values. What we retain are high-level heuristics — patterns about what valid data looks like — not the data itself.
Encrypted in Transit & at Rest
Any information under our control — such as heuristics and supporting service data — is encrypted in transit and at rest. Your insights stay protected.
AI Benefits Without the Risk
You gain the benefits of AI-supported checking and continuous learning, without handing over your raw data. For full details, see our Trust Centre.
