Set up Stripe Checkout for subscription billing
Your prompt
Add Stripe Checkout to handle monthly subscriptions. Create a /api/checkout route that accepts a priceId, creates a Stripe session, and redirects. Handle success/cancel URLs pointing back to /dashboard...

For the success URL, make sure to include a session_id query param — Stripe needs it to verify the purchase on return.
Should I use Stripe Elements or hosted checkout?
V
Hosted checkout — faster to ship and handles PCI compliance automatically.

How it works

From idea to shipped in three steps

Tell Vibier what you're building, and it generates a complete, sequenced prompt plan — no more guessing what to ask or blowing your context window.

01
Describe your project
Answer a few questions: what are you building, which AI tool you're using, and your experience level. Takes under two minutes.
02
Get your prompt plan
Vibier generates a phase-by-phase breakdown with pre-written, optimized prompts — each sized to avoid context overload and estimated cost.
03
Build step by step
Work through prompts in sequence. Mark done, flag errors, save great ones. An AI assistant answers questions about each prompt as you go.
Cost comparison

Most developers overspend by 3–5×

Without a plan, you're making the same mistakes in every session — resetting context, asking vague questions, re-explaining architecture. Vibier front-loads the thinking so the AI does it right the first time.

Without Vibier
Vague prompts → bad output → redo
Context resets mid-feature
No idea how much you've spent
Blocked waiting on AI to re-explain
Ship in weeks (or never)
With Vibier
Pre-written, scoped prompts that work
Context managed across sessions
Cost tracked per prompt and project
AI assistant answers in-context
Ship the first time, on budget
Platforms

Built for the tools you already use

Vibier generates plans optimized for each platform — knowing how Claude Code handles context differently from Lovable, or how to structure Cursor prompts for multi-file changes.

Claude Code
Terminal-first AI coding. Vibier generates file-scoped prompts that fit within Claude's context window.
Lovable
Full-stack app builder. Plans are sequenced to build UI, then logic, then integrations — in the right order.
Cursor
AI-native IDE. Prompts are sized for Composer sessions and scoped to avoid conflicting file edits.
Bolt
Fast prototyping. Vibier breaks features into single-shot prompts that Bolt can execute without confusion.
Chrome extension

Your plan, right inside Claude

Install the Vibier Chrome extension and your active prompt floats alongside Claude.ai — no tab switching, no copy-paste. Mark prompts done, see next steps, all without leaving the conversation.
