Describe it. Build it. Ship it.
Business owners chat. Developers code. AI agents build.
Same project, real-time, one workspace.
Business owners describe features in chat. Developers review the code. AI builds it all in real-time.

Multiplayer AI Chat
Your whole team. One AI. Every message shared.
Everyone chats with the same AI in real-time. When Priya asks for a login page, Marcus already has that context. The AI remembers Day 1 decisions on Day 100.
Add a login page with Google sign-in and redirect to dashboard after login
/dashboard after successful auth. Updated 3 files.Now add Stripe payment to the checkout — use the same auth session from the login
checkout.ts. Since Priya just set up Google OAuth, I'm reusing that auth session for payment verification — no extra login needed.Add unit tests for the checkout flow and the login page
Marcus didn't mention Google OAuth — the AI already knew because it heard Priya's request
Cursor and Claude Code are single-player. Each person gets an isolated AI that forgets everything between sessions. Dropstone is multiplayer — one AI that hears everyone and remembers everything.
What people say
Don't take our word for it
Large projects don't just need speed. They need memory. Context is the oxygen of AI-assisted development.

The 70% Problem
Where Lovable stops, Dropstone keeps going.
AI tools get you 70% of the way. Then you hit a wall — bugs, security flaws, features AI can't handle. Lovable and Replit leave you stranded. Dropstone puts a developer right beside you.
Lovable / Replit
Business owner is alone. Can't fix it. Starts over or hires someone.
Dropstone
Developer is right there in the workspace. Fixes it live while you watch.
Lovable / Replit
Business owner doesn't even know. App stays vulnerable.
Dropstone
Developer reviews code in real-time. Catches flaws before deploy.
Lovable / Replit
AI hits the 70% wall. Project stalls. You pay someone to rebuild.
Dropstone
Developer takes over that part. AI handles the rest. Nothing stalls.
Lovable / Replit
AI-generated code isn't production-ready. Full rebuild required.
Dropstone
Developer + AI agents harden it together in the same workspace.
Lovable builds your app. Dropstone builds your app AND makes sure it actually works.
Role-Based Views
Everyone sees what they need. Nothing more.
The code is under the hood — not everyone needs to see it. Like Figma adapts for designers vs developers, Dropstone adapts for business owners vs engineers. Same workspace, different interfaces.
Business View
For founders, PMs, and non-technical team members
Chat with AI in plain English. See a live preview of your app being built. Get status updates. Never see a line of code.
Developer View
For engineers who want full control
Full VS Code-compatible editor, terminal, git integration, and agent activity. Review AI-generated code before it ships.
AI Agent View
Transparent agent activity for the whole team
See what agents are working on, which files they're modifying, test results, and security scans — all in real-time.
Share with one link. Control who sees what.
Generate a shareable link to any workspace. Business owners get the chat view. Developers get the code view. Everyone stays in sync without stepping on each other's toes.
Think Figma. Designers and developers look at the same file but see different interfaces. Nobody questions whether Figma is “for designers or developers” — it's for both.
Background Agents
Your AI workforce never sleeps.
While your team focuses on strategy, background agents explore multiple solutions in parallel — testing for bugs and security flaws before showing anyone the result. Business owners see status updates. Developers see the full diff.

How it works
Explore
Agents explore multiple solution paths simultaneously, testing different approaches to your request.
Validate
Each solution is tested for bugs, security flaws, and edge cases before anyone sees it.
Deliver
Only the best solution is presented — verified, reviewed, and ready for your team.
10 agents included with Pro. 25 agents with Team plan.
