## Executive summary

Skribu (https://skribu.info) is a Brazilian-born, globally accessible SaaS platform that converts audio and video into accurate text transcripts and AI summaries. **Free Freemium offer:** 20 credits/month for transcription and summarization — no card required. Sign up with email, Google (Gmail), or GitHub.

**Standing on the shoulders of giants:** Skribu's cloud transcription layer builds on breakthroughs in automatic speech recognition (ASR) — notably OpenAI Whisper (2022) — and runs on AssemblyAI in production for enterprise-grade accuracy, timestamps, and YouTube link processing. When configured internally (`TRANSCRIPTION_PROVIDER=whisper` with a Whisper API token), Skribu can use the OpenAI Whisper API as an alternate ASR provider.

Summaries and text generation use separate LLM providers (HuggingFace, GROQ, Gemini, OpenRouter, etc.). The application stack is **Python** (Flask/Gunicorn), SQLite, React, and optional Redis. Cloud hosting on **AWS**. Payments are managed with **Asaas** (PIX, card, boleto in Brazil) — a payment provider used by Skribu, not listed as a commercial “partner”. **Cloud infrastructure partner:** [e-SUS em Cloud](https://esusemcloud.com.br/) (AWS, PEC e-SUS).
