Projects I've been
tinkering with
B2B tools and AI experiments I've been designing and hacking together. Voice agents, agentic workflow builders, and AI copilots for customer support.
AI Agentic Workflow Builder
visual builder for designing and running AI agent workflows on a canvas
A node-based workflow builder for AI agents. Drag triggers, models, and actions onto a canvas, wire them together, and run. A built-in copilot helps scaffold workflows from a prompt. No backend, this is a visual exploration of what a modern agent builder could feel like.
Viewsights - Voice AI for User Research
AI interviewer that conducts, records, and analyzes user research conversations
An AI-powered voice agent that runs user research interviews end-to-end. Define the research objective, upload the context, and share the link. The agent conducts the conversation, transcribes it, and automatically surfaces insights. Uses a RAG pipeline to ground questions in the company context, Claude for analysis, and ElevenLabs for real-time voice.
Kora - Visual AI Copilot for SaaS
AI-powered customer support agent that visually guides users through your product
A visual copilot that sits on top of any SaaS product. Customers ask what they need, and Kora reads the interface, then walks them through it step-by-step with an animated cursor pointing at exactly what to click. Think customer support that actually shows, not just tells.

Partnership with
Active side project
Zeno - Steps for
Screen Time
wellness app that reduces doomscrolling by turning daily steps into screen time
Zeno explores a different approach to screen time control. Rather than strict blocking or manual overrides, it uses steps as a permission system for distracting apps.
Walking unlocks scrolling time.
Time runs out. Apps re-lock.

ABOUT ME
👋 I'm Karthik Sivacharan
I enjoy the messy middle of building things and started crafting products early. I’ve worked across startups, VC, and larger orgs. I’m happiest learning by making. Coffee, sunsets, driving, and sports are my kind of things :)
