Storylane vs Supademo: Price, Platform, and AI Agents (And a Third Option)

Quick Takeaways

• Storylane and Supademo are the two most-reviewed interactive demo platforms with published pricing: Storylane is G2's #1 demo automation product (4.8, ~1,500 reviews) with premium RepX agents from $2,000/mo, Supademo is the value leader (4.7, 600+ reviews) from $38/creator/mo with a credit-metered AI Demo Agent — and neither agent drives a live product, only captures.
• Storylane's edge is platform weight: the largest review base in the category, HTML and sandbox demos, buyer hubs, and the three-mode RepX agent line launched August 12, 2026.
• Supademo's edge is the buying experience: a real free tier, self-serve checkout, a 14-day trial, and agent pricing metered in credits, 1,500 of them free.
• Full disclosure: we build Naoma, a competing agent that does drive the real product live and bills only on engaged demos — the third option at the end.

Cards on the table: we build Naoma, an AI demo agent in the same market as both products here. We wrote it anyway: this is the pair buyers shortlist when they insist on published pricing, and neither vendor has written an honest head-to-head. Everything below comes from their own pricing pages, docs, and G2 profiles as of August 2026.

For years this was a tour-builder decision: capture your product, edit a guided story, embed it. This summer both vendors added a conversational layer, ten weeks apart — Supademo's AI Demo Agent went GA on June 3, 2026, and Storylane answered on August 12 with RepX, AI sales agents sold on top of its Demo Suite. The question now is which platform's agent, pricing model, and proof fit the way you sell.

Quick comparison

What Storylane does

Storylane (San Francisco, Y Combinator S21) is the volume leader of interactive demos: the top-rated product in G2's Demo Automation category, with roughly 1,500 reviews at 4.8 and customers like Phenom, CodeSignal, and Avalara. Its Demo Suite spans fast screenshot captures, an editable HTML demo editor from the Growth tier, sandbox demos, buyer hubs, account reveal, and A/B testing — with prices published at every tier, still rare in this market.

RepX, launched publicly on August 12, 2026, adds the agent layer: it converses in text, voice, or AI-video mode, screens ICP fit without forms, surfaces Storylane demos, slides, PDFs, and videos inline mid-conversation, handles objections, books meetings, and pipes leads with summaries into HubSpot, Salesforce, and Slack. The caveat sits in Storylane's own docs: RepX presents what your team captured earlier — screenshot and video demos on RepX Growth, HTML on RepX Premium — a concierge for your demo library, not an agent operating the live product.

What Supademo does

Supademo (New York) claims 200,000+ users and owns the value position: a usable free plan, a published $38 per creator per month annual entry, and a Growth tier at $350/mo annual bundling HTML demos, sandboxes, voice cloning, and white-glove onboarding — capabilities rivals often reserve for four-figure tiers. The whole motion is self-serve: signup, 14-day trial, checkout, no sales call.

Its AI Demo Agent went GA on June 3, 2026. It runs structured discovery, qualifies intent, answers in 50+ languages, and serves the right asset — existing captures, videos, decks, pricing — then books a meeting, starts a trial, or hands off to a human by rules you set, with session summaries and intent signals flowing back. CTO Koushik Marka's launch line frames the ambition: "Most AI sales agents are generic chatbots wired to help docs. They talk about their product but can't show it." The agent does show something — the capture library your team built, orchestrated rather than driven live.

One architecture, two agent bets

Strip the branding and both agents share a skeleton: conversational AI in front of a pre-built demo library. The differences are packaging and posture.

RepX is the premium concierge: three modes including avatar-video calls on RepX Premium, meeting booking with alternative CTAs, "Ask RepX" analytics, and a CSM — with tiers capped at 10,000 and 40,000 monthly visitors. No language count is published, and prospect memory is not stated. Supademo's is the metered utility: an add-on from Scale up, 50+ languages, booking, trial starts, and human handoff, improving in aggregate — with no per-prospect memory claimed and a thinner avatar story than RepX Premium.

On the builder side they trade punches — Supademo's HTML-capable Growth costs $350/mo annual against Storylane's $500, while Storylane counters with account reveal, buyer hubs, and presenter tooling. What neither offers, at any tier, is an agent that operates your actual application in front of the buyer.

Pricing: traffic-priced concierge vs metered credits

Storylane's prices are published in full as of August 2026 on storylane.io/pricing: Free, Starter $40/mo annual, Growth $500/mo annual (five seats), Premium $1,200/mo annual (ten). RepX sits on top, priced by monthly website visitors: Growth "starting at $2,000/mo" for up to 10,000 visitors, Premium "starting at $3,000/mo" for up to 40,000. Vendr reports a median contract of $11,500/yr (reported, not list). The complaint G2 reviewers raise most — cost at scale, 98 mentions — predates RepX, and a $2,000/mo agent floor will not soften it.

Supademo prices its agent like a utility. Platform plans run Free, $38/creator/mo annual, and $350/mo annual per supademo.com/pricing; the AI Demo Agent bills by credits: $99 for 1,400, $299 for 5,500, $500 for 12,500, at one credit per response plus one per 15 seconds of voice. At GA the company framed the cost at roughly $0.50–$0.80 per qualified demo; its published typical-call math now lands at $0.80–$1.41 for a 15-minute conversation. Credits never expire, and every workspace gets 1,500 free (about 75 calls, per the vendor).

That makes Supademo the only vendor here tying agent cost to usage rather than a traffic band or a seat — the closest the tour category has come to outcome-linked billing. The step not taken: a credit is consumed whether or not the conversation went anywhere.

Reviews: the deepest base vs the fastest riser

Both give buyers something rare in demo software: large, independently browsable review bases. Storylane holds a 4.8 on G2 across roughly 1,500 reviews and the category's #1 spot; criticisms cluster on cost at scale (98 mentions), mobile experience (84), and features migrating into higher tiers. Supademo holds a 4.7 across 600+ reviews, 82% five-star; its cluster is missing features and limited customization (about 83 mentions), plus a narrow accent range on AI voiceovers and friction on very complex demos.

Read fairly, Storylane's base says "trusted at scale, watch the invoice," and Supademo's says "excellent value, occasionally hits the ceiling." Neither agent has third-party conversion data yet — both launched mid-2026 — so ask for numbers in any pilot.

When Storylane wins, when Supademo wins

Choose Storylane if you will use the platform's weight: HTML, sandboxes, buyer hubs, an avatar-capable agent with a CSM attached, and the largest review base behind the decision — with budget for $500/mo Growth and a $2,000/mo agent line. It is the enterprise-shaped pick.

Choose Supademo if value and speed decide it: HTML and sandbox demos at $350/mo, an agent switched on for $99 in credits and trialed against 1,500 free ones, and checkout without talking to sales. It is the fastest cheap experiment in demo automation.

Look elsewhere if what you want automated is the demo conversation itself, on the real product — both agents present captures, and that constraint is structural.

The third option: an agent that runs the real product live

Here we step in, clearly labeled. Naoma is a full-cycle AI account executive for inbound: it opens with discovery, then gives a live demo adapted to that buyer — slides where they help, the real product driven live in a browser session, branching journeys on Scale and Enterprise — handles objections, qualifies, and books the meeting or routes straight to signup and checkout, with CRM write-back. It speaks 33 languages, auto-detected and switchable mid-demo, ships best-in-class realistic avatars, branded mascots, and animated avatars (custom-built for you), added prospect memory and account enrichment in August 2026, and includes the high-converting website widget with built-in chat bot on every plan. The stack is in-house — roughly 20% faster conversational reaction than an ElevenLabs stack — and Naoma builds the demo for you rather than handing you an editor.

Billing goes one step past Supademo's credits: a demo is chargeable only after 3 minutes of engagement, and bounces are free. Published plans start at $299/mo on the pricing page; model your own traffic in the ROI calculator. Proof is public: Naoma has conducted more than 50,000 AI demos, and in the AiSDR case study, 53% of demos ran past three minutes, the average conversation lasted 7 minutes 50 seconds, 21% of demos produced a qualified lead, and 6% ended with a booked meeting — alongside a 4.9 on G2 and a 5.0 on Product Hunt. The honest ledger: Naoma is GDPR compliant with SOC 2 in progress, while both rivals hold SOC 2 Type II, and self-serve purchase with a free trial arrives in September 2026, so plans start with a walkthrough today.

FAQ

Should I pick Storylane or Supademo? Pick Storylane for platform depth, the category's largest review base, and a premium avatar-capable agent (RepX from a published $2,000/mo); pick Supademo for the lowest published entry ($38/creator/mo annual), self-serve checkout, and a credit-metered agent you can test on 1,500 free credits.

Is there an alternative to both Storylane and Supademo? Yes — Naoma, a live AI demo agent that drives your real product in a video conversation and bills only for demos with 3+ minutes of engagement, from a published $299/mo; see Naoma vs Storylane and Naoma vs Supademo.

Do Storylane and Supademo publish pricing? Yes, both as of August 2026: Storylane lists Demo Suite tiers from $40/mo annual and RepX from $2,000/mo on storylane.io/pricing; Supademo lists plans from $38/creator/mo annual plus agent credit packs from $99 on supademo.com/pricing.

Can Storylane's RepX or Supademo's AI Demo Agent demo my live product? No — both present demos captured earlier in screenshot, video, or HTML form, so the buyer never sees the real application driven live; agents that drive the live product, like Naoma, are a different architecture.

Which is cheaper, Storylane or Supademo? Supademo at almost every point: $38 vs $40 at entry, $350 vs $500 for the HTML-capable Growth tier, and agent credits from $99 versus RepX's $2,000/mo floor — a gap Storylane's own cost-at-scale complaints suggest widens as you grow.
