Overview
Tech stack
  • GPT-4o
    GPT-4o (omni) is OpenAI's flagship multimodal model: it delivers GPT-4 intelligence with native, real-time processing across text, audio, and vision.
    This is GPT-4o, OpenAI’s 'omni' model: a single neural network natively handling text, audio, and image inputs and outputs. It matches GPT-4 performance on English text and code, but surpasses it on non-English language, vision, and audio benchmarks. The speed is a major upgrade: it achieves human-level responsiveness in voice, with an average response time of 0.32 seconds (a significant jump from GPT-4’s 5.4 seconds). Developers get a 128K token context window and a model that is more cost-efficient than its predecessor, making high-intelligence, real-time applications viable.
  • n8n
    n8n (pronounced 'n-eight-n') is the fair-code workflow automation platform: it gives technical teams the power of custom code (JavaScript/Python) via a visual, node-based editor.
    This is n8n: a powerful, self-hosted workflow automation platform designed for developers and technical teams. It uniquely blends the speed of a no-code UI with the flexibility of custom code, allowing users to build complex, multi-step automations that other tools cannot handle. With 400+ integrations and native AI capabilities, n8n ensures you maintain full control over your data and deployment (on-prem or cloud). For example, you can build a workflow to automatically pull data from a private API, transform it with a custom Python script, and push the results to both Salesforce and a Slack channel, all from a single visual canvas.
  • Google Drive
    Google Drive is the secure, cloud-based file storage and synchronization service: access, share, and collaborate on files across all your devices (Windows, macOS, Android, iOS).
    Launched in 2012, Google Drive is a robust file-hosting service used by over 2 billion users for secure cloud storage and synchronization. Every account receives 15 GB of free storage, shared across Drive, Gmail, and Google Photos. The platform integrates seamlessly with the Google Docs Editors suite (Docs, Sheets, Slides), facilitating real-time collaborative editing. Users can store over 100 file types, manage permissions easily, and use the desktop app to back up specific computer folders: it’s the central hub for Google Workspace productivity.
  • Google Sheets
    Cloud-based spreadsheet platform: deliver real-time data analysis and multi-user collaboration across any device.
    Google Sheets is your cloud-native spreadsheet solution: designed for simultaneous, real-time collaboration. Teams can co-edit files instantly, eliminating version control issues. Utilize over 400 functions and formulas for powerful data manipulation (e.g., `VLOOKUP`, `QUERY`). Integrate directly with Google Workspace (Drive, Docs) and enterprise data sources like BigQuery/Looker for large-scale data analysis, all accessible via a simple web browser or mobile app. This platform ensures your operation runs on current, shared data: maximizing efficiency and minimizing data silos.
  • YouTube
    YouTube is the definitive global video platform: it hosts over 2.5 billion monthly active users and drives more than 1 billion hours of daily watch time, operating as the world's second-largest search engine (after Google).
    YouTube is the premier global video distribution network, a powerful Google subsidiary consistently ranking as the world's second most visited website. The platform commands an audience of over 2.5 billion monthly active users; viewers consume more than 1 billion hours of content daily. Functioning as the internet's second-largest search engine, YouTube drives discovery across diverse formats: long-form videos, Shorts (seeing billions of daily views), and live streams. Top channels, such as T-Series (with over 257 million subscribers), validate its massive creator economy and solidify its role as the essential hub for entertainment, education, and commerce worldwide.
