## What is IndexOS?

IndexOS is the offline-first technical suite for technicians and companies: guided diagnostics, mapped fault codes, technical diagrams and manufacturer cards, in four vertical apps inside a single app.

THE FOUR VERTICALS
• ElectraIQ — Industrial automation: PLC, drives, motors, photovoltaics
• HVACIQ — HVAC and refrigeration: boilers, splits, heat pumps, chillers
• HorecaIQ — Professional kitchens: ovens, refrigeration, washing, coffee
• BASIQ — Building automation: alarms, CCTV, access control, KNX/DALI

WHAT YOU GET
• Step-by-step guided diagnostics: from symptom to cause, with suggested tools and spare parts
• Fault codes by domain, mapped and explained
• Wiring diagrams and manufacturer cards you can check in the field
• Technical glossary and Learn paths
• Intervention history

OFFLINE-FIRST
All content works without a connection: perfect for plants, boiler rooms, professional kitchens and technical spaces with no wifi.

## Version history (last 4 releases)

### 1.3 — 2026-08-30

NEW: AI ASSISTANT

A technical assistant inside every section. Ask a question and it answers by citing the fault sheets in the app's own database, not with generic answers pulled from the web.

• It only answers technical questions in your field: industrial automation, air conditioning, professional kitchens, building automation
• 2 free questions per day, no sign-up
• Unlimited with IndexOS Pro

CONTENT

• ElectraIQ: Tesar and Thytronic protection relays, star-point fault, Thytronic alarm catalogue

IMPROVEMENTS

• Interface fully localised: last remaining untranslated strings removed
• Chat: send from the keyboard, fixed input field, more reliable answers on long questions
• Minor fixes

Everything else keeps working offline: error codes, guided diagnostics, diagrams and field tools.

### 1.2 — 2026-08-02

Technical AI Assistant
A new "AI Assistant" section in the menu, available across all areas (ElectraIQ, HorecaIQ, HVACIQ BASIQ). Ask technical questions in the field and get immediate answers about faults, protection relays, thresholds and procedures, with specialized context for each trade: industrial electrical, professional kitchens, HVAC and building automation.
The assistant is intentionally limited to the app's technical domain: off-topic questions are declined.
This version also includes keyboard fixes in the chat and layout improvements.

### 1.1 — 2026-07-08

Version 1.1 — more stable and more accurate.

• More reliable fault-code diagnosis: fixed an issue that could interrupt the search.
• Sharper recognition: the exact manufacturer code now appears first among the hypotheses.
• Localization and interface text fixes.

Thanks for using IndexOS — keep the feedback coming.
