DocRouter Flows: Visual Workflow Automation for Intelligent Document Processing

Andrei Radulescu-Banu •
Most document AI tools give you one-step LLM processing. The second a customer needs branching, agents, or human-in-the-loop, you need more. DocRouter Flows is a visual, document-native workflow system with first-class OCR/LLM nodes, sandboxed Python, and durable execution via node-level checkpoints—no Temporal cluster required. Lightweight to run, and in production at scale.

How AI Agent Memory Works

Andrei Radulescu-Banu •
How to design AI agent memory and how it behaves in production: extracting memory facts from the incoming prompt, deduplicating and reconciling them with existing entries in AWS Aurora pgvector, injecting prior facts into LLM context, and scalability/optimization strategies for selecting only the most relevant facts. Covered implementation with Mem0 and custom save & retrieve LLM prompts—now a standard capability across ChatGPT, Claude, Grok, and Gemini.

How To Embed an AI Copilot in Your Application

Andrei Radulescu-Banu •
How we embedded an AI copilot into DocRouter as a tool-calling Document Agent: the agent loop, tool approval UX, context injection, and the backend patterns that make agents reliable in production.

The 'One Codebase, Many Products' Playbook

Andrei Radulescu-Banu •
Shared our journey with The 'One Codebase, Many Products' Playbook at AnalytiqHub.com, turning one framework into a powerhouse for AI products. From building DocRouter.AI in 3 months to launching SigAgent.AI in 3 weeks, and customized AI portals for clients – it's all about slashing dev time with 90%+ reuse. Core Playbook Steps: Build Shared Foundations (React UI, FastAPI backend, MongoDB storage, and Claude Agent for workflows), Integrate Smartly (LiteLLM for LLMs and Stripe for seamless billing), and Scale with Ease (open-core for community, closed forks for clients).

SigAgent.AI - Tracing Claude Agents

Andrei Radulescu-Banu •
AI agents have become powerful and reliable, but you need to build them right. With 50% of new agents now built with Claude Code, the ecosystem has opened up for integration with MCP, marketplaces, plugins, and SKILLS.md. What's missing? AI Agent Evaluation for debugging during development, and for guardrails and monetization during deployment. SigAgent.AI specializes in tracing Claude agents using Open Telemetry and step-by-step, hook-level monitoring. We covered how to build Claude Agents with SigAgent.AI traceability, what works and what doesn't with MCP tools, CLAUDE.md, SKILLS.md and MCP-as-code, and how to stand up agent infrastructure for value-based and usage-based pricing.

How To Integrate Stripe Into Your AI Application

Andrei Radulescu-Banu •
How did we built Stripe billing into DocRouter.AI? The talk covered why Stripe was the right choice for scaling metered AI usage, our SPU (Service Processing Units) credit system inspired by Databricks DBUs, free tier → plans → a-la-carte credits with consumption waterfall, dynamic pricing config 100% in Stripe metadata, async Stripe API calls in FastAPI, and our MongoDB backend schema.

An AI Backbone for Document Processing

Andrei Radulescu-Banu •
At the Sundai MIT hackathon, we recently develop a flow that grades 5th grade quizzes against a configured rubric. DocRouter.AI implements the back end, with the teacher-in-the-loop able to correct the evaluations. We reviewed this hack!

A front-end UI specialized for this use case can be quickly developed with tools like Manus, Bolt AI, Cursor, Windsurf. The DocRouter is the a tech stack accelerator, just managing prompts and evaluations, with human-in-the loop, hiding the complexity of LLM workflows.

AI Document Workflows

Andrei Radulescu-Banu •
DocRouter.AI is a drag-and-drop UI that transforms unstructured docs into ERP data – integrated with MCP clients like Claude Desktop – building web dashboards, dynamically – for example, allowing consulting companies to optimize internal engineering resources allocated to contracted projects.

Smart Document Router

Andrei Radulescu-Banu •
The DocRouter.AI is an open source Document Understanding Tool. It performs data extraction, at scale, for intelligent automation in a number of verticals: Supply Chain, Healthcare, Finance.

It is implemented using:
– NextJS, NextAuth, TailwindCSS
– FastAPI, Pydantic
– AWS, MongoDB
– LiteLLM
– OpenAI, Anthropic, Gemini, Groq/DeepSeek

To Andrei's surprise, the Cursor AI editor wrote most of the DocRouter.AI code! We discussed how DocRouter.AI was coded.
