AI Personal OS — Telegram/Notion [Main Hub]

ProblemManaging personal productivity, habit tracking, and social interactions requires constant context-switching and manual data entry across multiple disjointed apps.
SolutionA Telegram-native AI operating system for personal productivity — a stateful multi-agent hub that routes voice and text messages to specialized sub-agents for task capture, day planning, social CRM, biometrics tracking, and semantic search. Built on a hub-and-spoke architecture with persistent Postgres memory and Supabase state management, each agent runs its own conversational lifecycle and commits structured data to Notion, Google Calendar, and Pinecone.
ResultUnified all life-management workflows into a single conversational interface, completely eliminating manual data entry.

API Gateway & State Manager

ProblemA multi-agent Telegram bot needs to gracefully handle context switching, user states, and multimodal inputs without mixing up conversational memories.
SolutionSyncs Telegram button interactions with Supabase DB to manage user states.
ResultEnsured zero context bleeding between sub-agents and provided a seamless, crash-free conversational routing experience.

AI Personal CRM Agent (Vector-Powered)

ProblemKeeping track of networking history is tedious. Standard text matching fails to handle nicknames, typos, or new contacts efficiently in Notion databases.
SolutionA specialized agent that manages social interaction logs. It utilizes Pinecone semantic search to accurately resolve contact identities, dynamically fetches/generates Notion tags, and employs strict output parsers (Guardrails) to validate JSON payloads before database mutations.
ResultAutomated CRM logging with 100% data compliance, instantly resolving ambiguous contact names via vector entity linking.

Context-Aware Biometrics Tracker

ProblemTracking daily health, habits, and productivity requires filling out complex forms manually, leading to friction and inconsistent data logging.
SolutionAn automated ETL pipeline that conducts dynamic, time-aware interviews. It implements a resilient "Two-Stage Commit" pattern: first backing up the raw narrative to Notion, then using an LLM to extract normalized properties (JSON) to update specific database fields.
ResultConverted unstructured daily reflections into structured biometric telemetry with zero data loss.

AI RAG Agent with Hybrid Postgres Search

ProblemStandard vector search returns irrelevant data because it cannot process strict relational constraints like exact dates, priorities, or task statuses.
SolutionAn advanced conversational RAG assistant. It features a Query Planner that parses natural language dates (NLP) and dynamically builds complex Hybrid Search queries, combining semantic similarity (pgvector) with strict SQL metadata filtering.
ResultAchieved high-precision knowledge retrieval, completely eliminating hallucinated responses for time-sensitive task queries.

Autonomous Scheduling Agent

ProblemLLMs are notoriously unreliable at executing calendar updates because they fail to check for existing schedule conflicts or handle updates deterministically.
SolutionThis execution-focused agent translates high-level textual daily plans into precise CRUD operations (Create, Read, Update, Delete) within Google Calendar.
ResultEliminated double-booking and manual calendar management through a highly deterministic execution pipeline.

Notion → pgvector sync

ProblemEnterprise or personal knowledge bases are inaccessible to AI agents without a reliable, automated ingestion pipeline that keeps vector embeddings up to date.
SolutionAutomated n8n pipeline that syncs a Notion productivity database to a PostgreSQL vector store using OpenAI embeddings. Classifies items by type, resolves cross-entity relationships, and upserts idempotently — enabling semantic search over personal knowledge without manual intervention.
ResultProvided the foundational vector infrastructure, ensuring all conversational agents operate on the most recent, synchronized data.

Let's automate something.

If you've got a repetitive process that should run itself, send it over. Most conversations start with a quick description of the manual steps.
