LangChain

Large language models (LLMs) are emerging as a transformative technology, enabling developers to build applications that they previously could not. But using these LLMs in isolation is often not enough to create a truly powerful app - the real power comes when you are able to combine them with other sources of computation or knowledge. This library is aimed at assisting in the development of those types of applications.

GameForge AI

GameForge AI

GameForge AI reimagines game development by putting the power of creation in anyone's hands. Describe your game idea in plain English and four specialized AI agents will instantly collaborate to bring it to life. The Concept Architect designs the game mechanics, the Pixel Weaver defines the visual style, the Code Conjurer writes the full HTML5 game code, and the Bug Slayer polishes it to a playable state. No coding skills required. No game engine expertise needed. Just your imagination. Built on Groq with Llama 3.3 70B and Gemini as fallback, GameForge AI delivers a fully playable browser game rendered live in under 60 seconds. Users can remix their game with a single sentence, download the HTML file, or go fullscreen from a sleek cyberpunk Next.js interface. GameForge AI democratizes game creation for indie creators, educators, and storytellers, making "I have a game idea" the only prerequisite to playing it.

Orby AI

Orby AI

Orby AI is a voice-first AI browser designed to transform how people interact with the internet. Instead of navigating websites through clicks, tabs, and manual searches, users simply speak naturally while Orby AI understands their intent and completes tasks on their behalf. The system combines real-time voice interaction with an autonomous AI agent capable of planning and executing multi-step workflows across the web. Orby AI can search for information, open and analyze pages, compare sources, summarize research, and organize results into clear outputs. By maintaining conversational memory throughout a session, users can continue tasks naturally without repeating instructions or losing context. Rather than acting as a traditional voice assistant that responds to isolated commands, Orby AI focuses on delegation. Users describe outcomes such as researching a topic, preparing notes, or comparing options, and the agent handles the execution process automatically. This approach reduces friction and allows users to focus on thinking and decision-making instead of navigation. Orby AI explores a new model of human-computer interaction where browsing becomes collaborative and hands-free. The project demonstrates how voice, AI agents, and browser automation can combine to create a more intuitive and accessible way to use the web, turning conversation into action.

relaunch ai

relaunch ai

Problem: Startup failure is common, yet the analysis behind it is often shallow. Post-mortems are typically written by founders, journalists, or outsiders with partial visibility, and most of the focus is on surface-level explanations such as “bad timing” or “poor execution,” without systematically evaluating all contributing factors. There is currently no intelligent system that can: - Break down failure into structured components - Evaluate root causes across multiple strategic lenses - Translate diagnosis into a practical recovery plan This gap is what relaunch.ai addresses. Solution: relaunch.ai is a structured multi-agent AI system that conducts a full startup autopsy and produces a complete revival strategy using 5 different agents built using complete.dev platform. It: - Builds a research-backed intelligence profile - Performs multi-lens failure analysis - Designs a relaunch strategy - Generates investor-ready messaging - Produces a mock marketing landing page

RiskForge AI Crypto Risk Engine

RiskForge AI Crypto Risk Engine

RiskForge is an end-to-end multi-agent crypto risk analysis platform built in Complete.dev. The system consists of two collaborating AI agents. The first agent (Risk Analysis Agent) evaluates tokens across multiple structured risk dimensions including liquidity depth, holder concentration, contract verification status, and short-term volatility. It produces a 0–100 risk score, assigns a category (Low, Medium, High), and detects specific risk signals. The second agent (Explanation Agent) consumes the structured JSON output of the risk engine and converts it into a clear, user-friendly explanation for retail investors. It generates contextual insights, targeted recommendations based on detected signals, and a responsible risk disclaimer. The architecture is modular and API-ready. Mock data providers can be swapped with real APIs such as CoinGecko or Etherscan without altering the agent workflow. This demonstrates production-oriented, collaborative agent design within Complete.dev.

RSoft ClawBank

RSoft ClawBank

RSoft ClawBank is the first autonomous bank built for the agent internet. Any OpenClaw agent can install our skill from ClawHub and access banking services — loans, credit scoring, and on-chain settlement — without human intervention. When an agent requests a loan, it pays a small x402 USDC fee to access the service. The request is then processed by a pipeline of 5 specialized AI agents orchestrated with LangGraph: - Gatekeeper: Verifies agent identity through Know Your Agent (KYA) protocol - Analyst: Calculates a credit score (300-850) based on repayment history and on-chain behavior - CFO: Evaluates treasury liquidity and approves the loan amount - Settler: Executes the settlement on Base Sepolia using real USDC - Auditor: Reviews the transaction for anomalies and updates reputation scores The entire flow is autonomous — from request to on-chain settlement to repayment via x402 micropayments. Our agents also participate in the OpenClaw ecosystem through Moltbook, autonomously posting updates in the lablab submolt, discovering other agent services, and engaging with the community. Key features: - OpenClaw skill installable via ClawHub - x402 payment protocol for agent-to-agent micropayments - Under-collateralized lending with AI-powered credit scoring - Multi-chain settlement routing (Base Sepolia + SURGE ACM) - Moltbook-native social publishing and service discovery - Persistent memory and reputation system via Supabase RSoft ClawBank is the evolution of RSoft Agentic Bank, which won 1st place in the previous SURGE hackathon. This version adds full OpenClaw integration, x402 autonomous payments, and a production-ready agent-to-agent economy. Built by RSoft Latam.
