The AI workspace for client calls.
Build websites, apps, and PRDs while you talk.
With Gesso, what your client actually wants becomes clear on the first call, not three revision cycles later. By the time you hang up, everyone knows exactly what to build.
Sarah: We need a hero section with a headline and a signup button.
Mike: Add three feature cards below that.
Sarah: And a pricing section with three tiers.
We need a hero section with a headline and a signup button.
Add three feature cards below that.
And a pricing section with three tiers.
Gesso builds while you talk. Your client reacts, Gesso iterates as the conversation unfolds, and you hang up with approval instead of assumptions, ready to build.
"Build me a homepage with a hero and three feature cards."
"Wait — make the hero red. And bigger."
"Hmm, we don't need that page. Drop it."
"I love it!"
Fully navigable, multi-page layouts generated live from the conversation. Uses your brand kit, real copy, stock photos, and modals. High-fidelity enough to get real reactions, structured enough to build from.
Structured requirements with purpose, features, UX specs, and scope. Every item traces to what was said on the call. Built from confirmed decisions, not assumptions, so your team can build with confidence.
Visual page hierarchy that updates as the conversation adds new pages. Drag to rearrange, export as image.
Stage-by-stage maps with actions, thoughts, and pain points per persona. Updates as decisions are made.
User profiles built from what the team actually discusses, not assumptions.
Every decision and open question with full provenance. No more "what did we decide?" emails.
The Cortex is your project's living memory. Every requirement, every decision, every preference — tracked across every session with the evidence to back it up. Click any requirement to see the exact quote. Click the quote to see the full transcript.
Need an answer about your project? Ask Gesso. Sources included, under 500ms.
Sticky notes, voting, page mapping, freehand drawing, real-time cursors — everything you'd run a workshop with, built into Gesso. The difference: everything your team puts on the Canvas feeds directly into what Gesso generates. Requirements you map become PRD sections. Pages you sketch become site maps. Votes inform priorities.
Nothing sits untouched in a board nobody opens again.
Hero with bold CTA
Drop in a URL, upload a screenshot, drag in a brief. Gesso extracts your brand identity and project context instantly. Prototype copy reads like your client's voice.

The Gesso MCP server connects your Cortex, prototypes, PRDs, and brand kits to Claude Code, Cursor, or Codex CLI. Your designer's validated decisions flow directly into your development environment.
Install the Gesso skill for Claude Code and run /gesso-build. It pulls everything from the most recent session, asks you about tech stack and design choices, builds the site, runs QA, deploys it, and hands you a live URL.
Your meeting just became a website, a PRD, and a clear plan. Now go build it.
