• Selfology Bot — AI-powered self-discovery assistant that creates personalized follow-up questions based on your answers

• LangMentor — Adaptive AI tutor that learns from your mistakes. 4 digitized textbooks, vector-based error tracking, unlimited personalized practice

• WriteRAG — Rule-based writing analyzer that teaches through your mistakes. Transparent feedback grounded in professional books/courses
• SignalAI — ML-powered content curator that parses Telegram channels, learns from your ratings, and filters out 95% of noise

• VoiceFlow — Speak thoughts into Telegram, AI transcribes, categorizes, and organizes into Notion with tags and metadata. Zero manual processing
• TranscriptFlow — Save YouTube links to Notion, wake up to readable transcripts. Extract knowledge 5x faster through reading than watching
