Why teams choose Supademo's agent over Karumi
Buyers see your product through an AI either way. The difference is whether the buyer clicks through and steers an interactive demo hands-on, or watches the agent drive it and decide where it goes.
Interactive HTML demos, not a passive screen-share

Common questions about Supademo vs. Karumi
How Supademo's AI demo agent compares to Karumi.
What is Karumi?
Karumi is an early-stage AI demo agent (YC F25). It runs a guided product demo on a video call, where the agent drives a live browser and the buyer follows along by voice or chat.
Teams sizing up Karumi usually line it up against Supademo's AI Demo Agent, which works the opposite way. It chats by voice or text, answers questions in the moment, and brings up interactive demos buyers click through hands-on, plus videos, decks, and slides, all self-serve on a full demo platform.
What are the best Karumi alternatives?
Supademo is the strongest Karumi alternative. Buyers click through interactive demos themselves instead of watching an agent drive a video call, on a full demo platform with transparent, self-serve pricing. 1Mind and Storylane round out the shortlist, detailed in our Karumi alternatives guide.
Teams tend to choose it when they want buyers steering interactive demos hands-on rather than sitting through an agent-led video call.
How much does Karumi cost?
Karumi publishes a single self-serve plan at $900/mo for 100 demo sessions, one agent, and one language; multilingual and higher limits sit on a custom Enterprise plan. That works out to about $9 per demo session at the cap, and more if you don't use all 100. On Supademo, a typical 15-minute demo call runs about $0.80 to $1.41, published on our pricing page, and covers 50+ languages.
So the typical call costs a fraction of Karumi's roughly $9 a session, and isn't limited to one language.
What is the difference between Supademo and Karumi?
Control is the difference. Supademo hands the buyer interactive demos to click through and steer, plus videos, decks, and slides, while Karumi's agent runs the video call and sets the path.
So a Supademo buyer navigates the product hands-on, while a Karumi buyer can ask by voice or chat but doesn't decide where it goes.
What can Supademo do that Karumi can't?
Karumi is just the buyer-facing agent; Supademo is the platform around it. You build interactive demos, record your screen for video demos, share them with anyone, and track who viewed what.
Layered on is a creator-side AI suite for voiceovers, voice cloning, and translation in 50+ languages, and the buyer clicks through and steers the interactive demo themselves instead of following the path Karumi's agent picks.
Is Karumi a good AI demo agent?
Karumi makes sense if you want a hands-off, agent-led demo on a video call, with the agent driving a live browser while the buyer follows along. Being early-stage (YC F25), it's worth confirming maturity, and a live agent driving a real browser can lag or misdescribe a feature mid-demo.
Supademo tends to win for teams that want buyers steering interactive demos hands-on. Its approved, pre-captured demos can't lag or go off-script on a live product, and it runs on a full demo platform with transparent pricing.
Why do teams choose Supademo over Karumi?
A hands-off, agent-led video call points to Karumi. Supademo is the choice when the buyer should actively explore the product instead of just following along.
Its AI suite ties a buyer-facing agent to a full demo platform, so buyers click through and steer interactive demos themselves, with an independent SOC 2 Type II audit behind it.
