Live products
click any card to open the full dossierAI quality audit for phone calls — recording in, scored PDF report out.
What it is
A service for sales and support teams. Upload a call recording (or a chat export) — it returns a speaker-split transcript, a score against a 7-point QA checklist with quote-level evidence for every score, and a ready-to-share PDF report. No setup: it runs in the browser.
How it works
Upload — MP3/WAV/M4A/OGG up to 90 minutes, or an already-transcribed dialog as XLSX/CSV/TXT.
Recognition — Whisper large-v3 transcribes, pyannote separates the speakers. Runs on a real GPU, progress shown live.
Analysis — an LLM scores the call against the checklist: greeting, needs discovery, objections, closing — each score backed by a quote.
Report — a PDF with the full transcript, per-criterion scores and growth points. Files are deleted after processing.
Key capabilities
- Audio up to 90 min — long calls are auto-segmented
- 9 recognition languages + auto-detect
- Text dialogs too: chat / CRM exports (XLSX, CSV, TXT)
- Anti-hallucination scoring: every score cites the transcript
- EN/RU interface, live progress bar
Under the hood
A language school inside Telegram — from zero to C1, playing like a game.
What it is
A Telegram Mini App that teaches English from absolute zero to C1. Lessons feel like a game — modules on a map, Duolingo-style quizzes, hints under spoilers. The difference: free-form answers are graded by an LLM like a live tutor, voice-overs sound native, and your speech gets recognized and checked.
How it works
Module map — a course path from sounds and first words to complex grammar, checkpoint by checkpoint.
Lesson — short theory in a friendly tone, typical mistakes of Russian speakers, then straight to practice.
Practice — button quizzes plus free written and spoken answers — the LLM explains what's wrong, not just "incorrect".
Sound — every phrase is voiced with a natural voice; speech recognition checks your pronunciation practice.
Key capabilities
- Full A0→C1 program designed as one coherent course
- LLM grades free answers with explanations
- Native-sounding TTS for every phrase
- Speaking practice with speech recognition
- Lives entirely inside Telegram — nothing to install
Under the hood
Taxi, carpool and freight platform — two Android apps, live in 6 cities.
What it is
A ride-hailing platform for mid-sized cities: taxi, carpool and freight in one Android app. Passenger and driver share a single app with a role switch; a separate admin app manages the fleet. Real-time dispatch over WebSocket, push notifications, driver verification with encrypted documents. Running in production across 6 cities.
How it works
Order — a passenger books a quick ride, a scheduled carpool seat, or a freight run — on an OpenStreetMap map.
Dispatch — drivers see the order instantly over WebSocket; push notifications catch those offline.
The ride — in-app chat, live statuses, driver ratings after completion.
Operations — the admin app: driver verification queue, subscriptions via YooKassa, broadcasts to cities.
Key capabilities
- 3 services in one: taxi, scheduled carpools, freight
- Passenger + driver roles in a single app
- Real-time dispatch: WebSocket + FCM push
- Admin app: verification, subscriptions, broadcasts
- Driver documents encrypted at rest
Under the hood
An interactive school for developers — 12 hands-on tracks, in Telegram and offline.
What it is
A learning platform for developers: 12 practical tracks — Python, Docker, Git, SQL, DevOps, networking, neural nets, algorithms, patterns, testing, bash and APIs. One content source drives three frontends: a Telegram WebApp, an offline Android app, and a standalone neural-networks course.
How it works
Pick a track — from Python basics to DevOps practice — each is a sequence of compact lessons.
Learn by doing — theory in small portions, immediately backed by exercises and real commands.
Anywhere — in Telegram on any device, or fully offline in the Android app — same content, synced from one source.
