Prompt.me AI (promptmeai)

Send one prompt to multiple leading AI models and compare streaming answers side by side. Sign in, use platform credits or your own provider keys, save comparison history, and top up via Stripe. Live site: prompt.me.

Features

Verified from the current codebase:

• Parallel multi-model chat against four configured models (src/constants/modelNames.ts): GPT-5.5 (OpenAI), Claude Sonnet 4.6 (Anthropic), Gemini 3.5 Flash (Google), Mistral Small 4 (mistral-small-latest)
• Streaming via Vercel AI SDK (streamText + @ai-sdk/rsc) in src/actions/generateActions.ts
• Usage modes: platform credits (server provider keys + credit ledger) or bring-your-own API keys (stored on profile / settings)
• Auth: Google popup, email/password, email link (/loginfinish); password reset; account deletion
• Chat history with pin/search/delete; Zustand stores for auth, profile, credits, chat, payments, etc.
• Stripe PaymentIntents for credit purchases (/payment-attempt, /payment-success, /settings)
• Themes (next-themes), markdown responses, cookie consent, privacy/terms/support pages
• Route gate in src/proxy.ts (cookie presence); authoritative checks via Firebase Admin verifyAuth + Firestore rules

Firebase / Stripe setup

1. Enable Google, Email/Password, and Email link auth as needed.
2. Deploy firestore.rules and storage.rules (firebase.json / .firebaserc).
3. Configure Stripe keys and catalog purchase amount validation (src/utils/paymentAmount.ts / credit ledger).

Run locally

npm run dev

Open http://localhost:3000. Chat UI lives at /chat after sign-in.

Scripts

Script	Description
npm run dev	Next.js development server
npm run build	Production build
npm start	Serve the production build
npm run lint	ESLint
npm run typecheck	tsc --noEmit
npm test	Vitest
npm run doctor	react-doctor

Testing and CI

• Vitest covers proxy/routes, payment amount helpers, token/text/object utilities, and related modules.
• CI: npm ci --ignore-scripts, lint, typecheck, test, doctor, build (Node 22). Public Firebase/Stripe env for build come from Actions secrets when set; client init soft-skips when missing.
• malware-scan.yml runs static IOC matching via scripts/malware-scan.sh.

Deployment

Production: prompt.me. Set all required env vars on the host. Keep Firestore rules in sync so clients cannot mutate frozen credit fields.

Contributing

1. Branch from dev.
2. Keep verifyAuth + credit ledger checks on generative and payment actions.
3. Run lint, typecheck, and tests before opening a PR.
4. Never commit secrets or .env.local.
