🔬 Local-first · Privacy-preserving · AI-powered · Multilingual

Professional test data analysis.
Your data stays with you.

A desktop app for measurement analysis - load 31+ formats, compare runs, process signals, batch-report, and ask Axy about your data locally. The interface supports English, German, French, Brazilian Portuguese, Simplified Chinese, Italian, Spanish, Korean, and Japanese, with global and per-file regional decimal/date settings. The website handles downloads, accounts, and optional cloud sharing - not in-browser analysis.

🔋

Battery & Fuel Cell Researchers

Domain-specific KPIs for fuel cell stacks, battery characterisation, and thermal analysis. Ships with FCT stack report templates and battery/thermal analysis profiles.

🧪

Pharma & Lab Scientists

Native support for AIA/ANDI CDF chromatography, mzML mass spectrometry, JCAMP-DX spectra, Thermo RAW, and Sciex WIFF. Integrated with ISO 17025-style metadata reporting.

📊

Test & Data Engineers

Batch-process folders of CSV/TDMS/HDF5 files. Run automated pipelines (health → compare → limits → analyze → report). Export PPTX/Word/PDF from templates in one click.

Guided Engineering Workflow

From raw data to polished report in 5 steps

Every project follows the same guided flow. Click a step in the ribbon to jump directly - Vizalyze keeps everything in sync.

1

Load

Import 31+ file formats with smart preamble parsing, CAN decoding, custom import templates, and locale-aware decimal/date parsing. Preview before loading. Parquet cache for instant re-open.

2

Health

Automatic data quality check. Detects missing data, constant channels, timestamp conflicts. Pass / Warn / Fail badges with recommended fixes.

3

Compare

Overlay multiple runs with 6 alignment modes: time column, uniform resample, event-based, setpoint crossing, trend t=0, or row index. Delta tables and lineage tracking.

4

Analyze

Statistics, correlations, unit consistency, limit evaluation, and domain-specific KPIs. 8 domain profiles including fuel cell, battery, pharma HPLC, and vehicle emissions.

5

Report

Batch export to PPTX, Word, and PDF from reusable templates. Auto-summary merges Health + Compare findings. Pipeline recipes save the full workflow for reuse.

AI Integration

Ask anything about your data

Vizalyze has a built-in AI chat panel that understands your loaded data. Bring your own API key or use local models - your data never leaves your machine.

💬

Natural language queries

Ask "which channel has the highest variance?" or "generate a low-pass filter at 5 Hz" - the AI reads your actual column names and values.

✨

AI-assisted code panel

Write computed column formulas or filter conditions in plain English. AI autocompletes channel names, suggests Polars expressions, and explains errors inline.

🎨

Chart styling & automation

Ask the AI to apply colors, set Y-axis limits, highlight anomaly regions, or generate a full batch report recipe - then save it for reuse.

Bring your own API key for any provider:
