Zorai is an AI-powered content operations platform for generating, reviewing, scheduling, and publishing content across multiple channels.
It combines:
FastAPI backend for orchestration and APIs
React frontend for operators and reviewers
PostgreSQL + pgvector for persistence and semantic retrieval
Redis + Celery for background processing and periodic automation
OpenAI models for generation, analysis, and embeddings
LightRAG for graph-based knowledge retrieval
Optional integrations for X, LinkedIn, Substack, Reddit, Firebase notifications, and email verification
The core idea is turning your existing knowledge (uploaded documents, transcripts, discovered ideas, and feedback) into a repeatable publishing workflow using hybrid retrieval:
Vector retrieval (pgvector) for directly relevant passages
Graph retrieval (LightRAG) for conceptual relationships and thematic synthesis

ProposalGPT is a multi-tenant proposal-generation platform that combines a FastAPI backend, Next.js frontend, PostgreSQL, and pgvector retrieval with LangGraph-style workflow orchestration plus Celery and Redis for background execution.
The core flow is retrieval-augmented proposal drafting: it generates a proposal structure first, then builds the full proposal section-by-section by running targeted retrieval (similarity search over uploaded RFQ and optional company documents) and generating each section from that retrieved context. It can also retrieve relevant past winning proposals by embedding similarity to use as examples.
Users typically sign in with Google, upload/select an RFQ-like document (plus optional company docs), create a session, chat to request answers or a full proposal, iterate via feedback (resume from checkpoints), then approve and export the final proposal to Google Docs/Drive.

EmailGen (also branded in places as InfiniMail and ColdReach) is a multi-product SaaS platform focused on AI-assisted outbound email operations plus document intelligence.
Outreach / cold email automation: build campaigns from uploaded companies/leads, generate and schedule emails (including multi-step AI sequences), send via Gmail, Outlook, platform SMTP, or custom SMTP, and track opens, clicks, replies, and delivery outcomes. It also includes sending-domain management with DNS verification and domain warm-up, plus a unified inbox for workspace mailboxes.
DocuGenie: a case-based document workspace where you upload files (PDF/DOCX/XLSX/TXT), extract and chunk text, embed into a vector store, ask AI questions over the materials, and generate professional emails from the case content.
Under the hood it’s a monolithic codebase with clear subsystems: Next.js frontend, FastAPI backend, PostgreSQL + pgvector, and Redis + Celery for background jobs, with integrations to external providers like Google/Microsoft email and payment gateways.

I’m sharing MailCheckr: a full-stack email aggregation and alerting platform that lets you connect multiple IMAP mailboxes, continuously syncs folders/messages into PostgreSQL, and helps you quickly spot financially important emails (invoices, payments, quotes) with real-time progress updates plus notifications (email + Telegram).
If you manage multiple inboxes and want faster signal over noise, I’d love feedback and early users
