Problem → solution → tech stack.
A free tool that reads a store's public support pages and mirrors back how an AI agent would handle their top tickets - grounded replies, honest cost and coverage estimates, and a shareable result card. Built so every use is its own distribution.
Four products - a multilingual marketing site, an agentic AI sales concierge, a HubSpot-replacement CRM, and a post-sale customer portal - for a Swiss aircraft dealership, shipped as one Next.js app on one Postgres.
An end-to-end agentic system that runs an entire job-search funnel - discovering, scoring, tailoring, submitting, handling recruiter replies, and even placing screening phone calls - instrumented so every action is logged, gated, and reconcilable to the cent.
Three years after banning generative AI entirely following a source-code leak, Samsung Electronics is now deploying ChatGPT Enterprise and Codex to its entire Korean workforce and global Device eXperience division - marking one of OpenAI's largest enterprise deployments to date.
A paper posted to arXiv on June 15, 2026 introduces Orchestra-o1, an omnimodal agent orchestration framework that coordinates specialized AI sub-agents across all major input modalities - and reports a +10.3% accuracy gain over the prior state of the art on OmniGAIA, an established community benchmark for omnimodal agentic tasks.
A new paper accepted at ICML 2026's AI4GOOD Workshop audits the three most popular agentic AI frameworks - LangChain, AutoGPT, and the OpenAI Agents SDK - and finds zero native compliance with basic structural safety and containment principles.
Instead of waiting for store owners to find the tool, this system pre-scans their store, then emails them a link to their own AI-written support teardown - a closed loop that sources, qualifies, analyzes, and converts, with every move logged to a team dashboard.
