Built with Flowise. Built with Flowise. Leverage as a reusable component With agent templates, tool schemas and source codes. ## 6 database agent options The Analyzer micro-app on REX-3 ([tigzig.com](http://tigzig.com/)) offers 6 agent options, all capable of: * connecting to any database (with credentials) * natural-language-to-SQL * natural-language to python (for charts & stats) App also allows on-the-fly Postgres database for file uploads and temp use **AI backend is on Flowise AI. Leverage as a reusable component:** * directly via Flowise's native UI (Click → Share Chatbot → Live) * plugged into any UI via API (as in REX-3) * integrated into automated workflows via API Easy to setup, modify and maintain. ## Standalone General Analyst Single-agent setup for regular queries & simple analysis. Uses o3-mini; for complex cases, I use gpt-4o ## Multi-Agents (technically sequential agents in Flowise, Backend: LangGraph) Three-agent flow: Gemini-Flash-2 / o3-mini / Deepseek-R1. Agent flow: * **Router Agent** → Determines if a query goes to General or Advanced Analyst * **General Analyst** → Same as standalone version above * **Advanced Analyst** → * Step 1: Reasoning LLM (o3-mini / Flash-2 / Deepseek-R1) generates analysis plan & SQL * Step 2: gpt-4o agent verifies query accuracy, executes, and returns results ## Multi (Sequential) Agents with Additional Debugging Still in testing. Similar to sequential agents but with: * one has and additional error-checking step * other is a debugger agent for routing based on user request ## Take them for a spin Feel free to test out with different data/query complexity/agent choices-no API key needed. Connect to your database or use the temporary Postgres DB (created on-the-fly for file uploads). Upload your own files or just hit the 'Sample' button for sample file upload. ## Source Codes/ Resources * **Flowise agent templates & tool schemas** All schemas + source codes → [www.tigzig.com](http://www.tigzig.com/) (Help & Build section) * **Detailed Video Guide – Demo & Build Walkthrough** Covers: Agent architecture, SQL errors, API failures, error handling, cost, performance, quality, latency * **Top Flowise Resource** Leon van Zyl's YouTube → @leonvanzy (best guide out there) Explore 15+ open-source AI analytics apps at tigzig.com with natural language to SQL, python charts, stats, database connectivity and more.
