Stop re-explaining your project to AI every session.
Your specifications are your competitive advantage. 4ge is the context engineering platform that turns raw ideas into token-optimised, AI-ready briefs, acting as a massive force multiplier for Cursor, Windsurf, and Claude Code.

97% of developers lose time to daily inefficiencies. But for AI-native developers, the biggest bottleneck isn't writing code anymore. It is context engineering.
Every time the AI guesses wrong, you pay for it twice in time and API costs. Research shows 60% of an AI agent's time is wasted iterating on poorly defined prompts. You're burning tokens on rework instead of shipping new features.
Moving fast in Cursor is an illusion if you have to rewrite the output. 68.3% of AI coding failures are caused directly by underspecification. When the AI lacks constraints, it builds the wrong thing perfectly, delaying your launch.
Dumping your entire codebase into a context window doesn't just degrade output quality, it maximises your API bill. Teams using AI without structured specs see a 91% increase in PR review time untangling hallucinated boilerplate.

### TASK: `feat/stripe-payments`
**Objective:**
Implement Stripe processing supporting one-time & monthly subscriptions.
**Existing Architecture:**
* Auth: NextAuth.js with JWT
* DB: PostgreSQL via Prisma
* Validation: Zod schemas in `/lib/validations/`
**Explicit Constraints:**
1. Use existing `requireAuth()` middleware.
2. Never expose Stripe secret keys in client-side code.
3. Use idempotency keys for all charge attempts.### TASK: `webhook/stripe-events`
**Objective:**
Implement webhook handlers for subscription events.
**Acceptance Criteria:**
1. Verify Stripe signature using `stripe.webhooks.constructEvent`.
2. Handle `customer.subscription.deleted` by updating User tier.
3. Return 200 immediately to Stripe before heavy DB ops.A guided workflow that eliminates prompt iteration loops and gets you back to building.
Type a single-sentence idea. No formatting required. Get your thoughts out while staying in the flow state.
4ge automatically drafts the architecture, data models, and API constraints based on your existing stack.
Visually review the logic flow to ensure no unstated assumptions slip through to the LLM.
Export token-optimised, AI-ready specifications that leave zero room for hallucinations.
Feed the brief into Cursor or Windsurf and watch it generate production-ready code on the first attempt.
Cut your spec-to-handoff cycle from weeks to hours. 35% of total project timelines are lost to rework from poor requirements. These benefits directly address that waste.
What used to take days of writing, rewriting, and clarifying now takes hours. Map your feature visually, let 4ge fill in the details, and hand off complete specs your developers can build from immediately. Stop spending 60% of your time clarifying what you meant.
Teams that design only for the happy path ship features that fail in the real world. 4ge's AI partner spots the error states, empty screens, and edge cases you might have missed - before development starts. Projects with rigorously documented requirements are 97% more likely to succeed.
When you say "user flow," developers hear something different. Same words, different meanings - $58,500 in monthly overhead for a 10-person team. 4ge creates living blueprints everyone can read: you see the user journey, developers see the implementation path.
Stories written as "As a user..." strip away the context developers need. The result? Features that ship, but don't solve real problems. 4ge's flow canvas grounds every feature in the user's actual journey - not a generic persona - so developers understand the "why" behind the "what."
Turn 4ge specs into Jira tickets with full context attached
Sync 4ge blueprints directly to Linear issues
Import context from existing repositories; bi-directional status sync keeps your plan canvas in sync with issue status
Specs work directly with Cursor AI
Optimized output for Cascade and chat-based workflows
Model Context Protocol endpoints for custom AI agent integrations
4ge enhances your project management tools by creating the clarity that goes into your tickets. Better specs, better tickets, better outcomes.
Coming Soon: Automatic status updates - when a Jira ticket moves to "In Progress," your 4ge plan reflects it instantly. No more manual status tracking across tools.
Join the waitlist and be among the first AI-native developers to completely eliminate context overflow.
