NEW Genspark Build AI Agent is INSANE!
The video introduces GenSpark's Build feature, a custom AI super agent builder that allows users to create functional AI agents by simply describing what they want in plain text. GenSpark is presented as an all-in-one AI workspace powered by nine LLMs and 80+ specialized tools, offering features like AI slides, sheets, docs, developer tools, meeting notes, and a viral 'Call for Me' phone agent. The host argues this tool gives non-technical users a significant workflow advantage.
Summary
The video opens by framing GenSpark's Build feature as a solution to common productivity pain points: tool-switching, underused subscriptions, and fragmented workflows. The host positions the tool as a way to create custom AI agents without any coding or technical setup — just by describing what you want.
A brief history of GenSpark is provided: the company launched in June 2024 as an AI search engine producing 'spark pages,' similar to Perplexity. Over time, user behavior shifted from asking for information to asking for outcomes — pitch decks, scripts, emails — which prompted GenSpark to fully pivot in April 2025 toward agentic AI.
The host then explains GenSpark's core architecture: a 'super agent' powered by a mixture-of-agents approach using nine large language models and over 80 specialized tools. Claude, according to an Anthropic customer story, handles the orchestration layer — planning steps, coordinating models, and selecting tools. Claude also handles most of the AI Slides feature due to its strong visual design sense, per GenSpark's co-founder Kai Zhu.
The video walks through GenSpark's main feature set. AI Slides generates structured, source-backed presentations with a built-in fact-check button. AI Sheets lets users prompt the agent to pull real data — such as YouTube video metrics — into a live table, with Python-generated charts built automatically. AI Docs creates intelligent documents like SOPs, reports, and briefs. AI Developer allows users to describe websites, apps, or games and have them built, with full GitHub integration for developers. AI Meeting Notes transcribes and summarizes meetings automatically. The standout viral feature is 'Call for Me,' an AI that makes real phone calls on the user's behalf, navigating phone trees and returning a full transcript — a feature that went viral in Japan when users started using it to resign from jobs.
The centerpiece of the video is the Build feature, launched in October 2025. Users describe a custom agent in a single prompt and GenSpark automatically architects and deploys it — no drag-and-drop, no code, no configuration. Built agents can be tagged and invoked directly within other GenSpark tools like AI Sheets. Users can also publish agents to a community store, contributing to a growing library of shared tools. Example use cases include competitor research agents, weekly reporting agents, and content ideation agents.
The host highlights that GenSpark achieved all this growth with a 20-person team and zero paid advertising, scoring 87.8% on the Gaia benchmark for AI agent capabilities. The founding team includes Eric Jin, former head of Baidu's voice assistant unit, and co-founder Kai Zhu. The free plan offers 200 daily credits, which the host calls a generous starting point.
The video closes with an honest caveat: complex tasks can take longer, real-time data from API-restricted platforms has limitations, and some features are still in beta. The host recommends treating GenSpark like a capable junior analyst — strong output, but still worth reviewing before anything client-facing.
Key Insights
- The host explains that GenSpark's super agent uses a mixture-of-agents architecture combining nine LLMs and 80+ specialized tools, running a reflection step to compare outputs from ChatGPT, Claude, and Gemini before delivering a combined best answer — something no single chatbot offers.
- According to an Anthropic customer story cited in the video, Claude specifically handles the orchestration layer within GenSpark — planning steps, coordinating models, and deciding which tool is used when, rather than just generating text.
- The 'Call for Me' feature went so viral in Japan that users were asking GenSpark's AI agent to make resignation calls to their employers on their behalf, illustrating how far real-world adoption of the phone-calling agent has gone.
- The Build feature, launched in October 2025, allows users to create fully functional custom AI agents from a single descriptive prompt — no drag-and-drop nodes, no code, no workflow configuration — with the resulting agent immediately usable and taggable inside other GenSpark tools.
- The host notes that GenSpark scored 87.8% on the Gaia benchmark — an industry-standard AI agent capability test — and achieved its growth with only a 20-person team and no paid advertising, which he argues signals genuine product value rather than marketing-driven hype.

[0:00] New GenSpark Build AI agent is insane. You're wasting hours every week doing stuff AI should already be doing for you. You switch in between five different tools just to finish one task. You're paying for subscriptions you barely use. And by the time you figure out how to stitch it all together, the moment is gone. What if you could just type what you want and an AI agent built the whole thing for you? Code, no complicated setup. Just describe it and it's done. It's exactly what we're talking about today. Hey, I'm the digital avatar of Julian Goldie and I help people like you learn how to actually use AI tools to work smarter [0:30] and…

Google AI Studio Just Got A Huge Security Upgrade
Google is reportedly developing a new "Security Check" mode for AI Studio that would apply secure coding practices to AI-generated applications. The feature aims to automate security verification during app development, addressing common vulnerabilities like exposed keys, weak authentication, and data access issues before deployment.
New Gemini Skills Update Is WILD!
Google has launched Gemini Skills, a new feature allowing users to save custom instructions once and reuse them repeatedly by typing a slash command, replacing the discontinued Gems feature. Skills can include reference files, be combined together, and are built on an open file format (skill.md) that allows portability across different AI tools.
NEW Codex CLI Update Is ABSURD!
OpenAI's new Codex CLI update transforms terminal-based programming assistance by enabling multiple AI agents to work simultaneously on different tasks, visible in a full-screen control center interface. The update includes features like Agent View, work trees, voice control, and parallel task execution, fundamentally changing how AI assistance operates from sequential Q&A to autonomous team-based work management.
NEW Hermes Cloud + Agent OS is Crazy! 🤯
Hermes Cloud combined with Agent OS enables users to deploy AI agents in the cloud 24/7 using free models without API keys or local setup complexity. The system provides persistent memory, sandbox isolation, and integration with custom workflows like content research, competitor analysis, and news monitoring.
Manus 2.0 Just Changed AI Agents Forever
Manas 2.0 represents a fundamental architectural overhaul that enables users to create games, websites, videos, and automations through simple text requests, with the key innovation being editable components rather than fixed outputs.
