Full-stack call analysis platform with AI

A full-fledged AI call analysis platform with a web interface for managers and executives.
What has been done:

Transcription of audio → text and storage in the database.

Call classification: technical vs product presentation.

Detection of trigger zones: which products the manager offers most often, adherence to the script, handling objections.

Quality metrics and automatic KPI calculation. Confirmed accuracy of AI evaluation — 85%.

Manager interface: viewing transcripts and AI conclusions, chat with AI about a specific call (context already loaded).

Executive interface: filters by team/call types, export of summary reports for N-period.

Integration with CRM: calls are automatically sent to the backend via webhook/API; then — a complete processing cycle without human involvement.

History storage: all transcripts, analyses, and dialogues with AI are stored in PostgreSQL.

Technical stack: React (UI), Node.js + n8n (backend), MySQL (database), Whisper/AssemblyAI/OpenAI and Gemini.
Result: 100% of calls are automatically analyzed; managers receive accurate prompts, executives get clear analytics and reports.
