FaceAiPro – AI Reel Studio SaaS: Talking AI Presenters, Voices & Captions (Next.js + MongoDB + Stripe)

FaceAiPro is a complete subscription business for short-form video, built by DEV3 Technologies on Next.js 15 (App Router), MongoDB and Stripe. A customer types a topic, a brief or a product link and gets a ready-to-post 1080×1920 reel for Instagram Reels, TikTok and YouTube Shorts: an AI-written script and storyboard, a natural voice, word-by-word karaoke captions, AI scene images and a talking AI presenter, rendered to MP4 by a background worker. It comes with a marketing site, a customer studio, an admin panel, Stripe subscriptions and a credit system.

Try it: the live demo is read-only, with one-click demo logins on the sign-in page (password Demo@12345): pro@faceaipro.test, business@faceaipro.test, creator@faceaipro.test, free@faceaipro.test and the platform admin admin@faceaipro.test. Rendering and AI generation are switched off there, because they run on your own server; the bundled sample reels and the browser preview show the result.

Reel studio

• AI script and storyboard from a topic, brief or product URL (the page's real content and screenshots are used), in any language, tone and length, plus the Instagram caption.
• Talking AI presenters: an animated talking photo (blinks and mouth shapes from the audio) or an Omni AI presenter that is a real talking video, in bubble, card, split, full-screen and host-plus-cutaway layouts. Eight preset presenters are included, and customers create their own from a description or a photo.
• Voices: hundreds of free neural voices in 70+ languages, plus premium AI voices with a delivery style you describe on paid plans.
• Karaoke captions: word-by-word highlight, box or outline styles, fonts, colours, position, size and uppercase.
• Storyboard scenes with AI images, uploads or imported media, zoom and pan motion and fit modes, timed to the voice.
• Cover image with accent words and an optional intro frame, background music with a volume control, and loudness normalised to −14 LUFS.
• Live browser preview: the demo player plays the real voice, captions, presenter and scene timings before any credits are spent, using the same timeline code as the renderer.
• Autosave, duplicate and archive projects, and a media library for images, video clips and music.

Rendering

• A background render worker (ffmpeg) leases jobs from MongoDB with heartbeats, retries and a stuck-job reaper; run as many workers as you need.
• 1080×1920 or 720p H.264 MP4 at 30 fps, the cover JPG and the caption in one download.
• Content-addressed caches for voices, presenter frames and presenter clips, so re-renders never pay twice.
• Works with ffmpeg builds without libass: all text is drawn with canvas.

Subscriptions, credits and billing

• Plans with monthly and yearly prices, feature flags (watermark, HD, premium voices, AI images, Omni AI presenters, custom presenters) and monthly credits, all edited in the admin panel.
• Credit ledger: atomic, never negative and idempotent; credits are reserved when a job is queued and refunded automatically on failure or cancellation.
• Credit packs, upgrades, cancellations and resumes, with Stripe Checkout, the Customer Portal and webhooks. Without Stripe keys, billing runs in a built-in simulated mode, so the whole checkout flow works before you connect your own Stripe account.

Customer panel and admin panel

• Customers: dashboard with credits, plan, recent projects and reels; the studio; a reels gallery with a player and downloads; the media library; the presenter library; billing; and account settings with active sessions.
• Admins: revenue, MRR, subscribers, renders, queue and signup charts; users (credits, plans, suspension, session revocation); subscriptions; payments; the plans editor; render jobs with retry and cancel; preset presenters; contact messages; site settings and credit costs; and the audit log.

Platform

• A marketing site with a react-three-fiber 3D hero of orbiting presenter reels, pricing, features, contact and legal pages, in a glassmorphism UI on Tailwind CSS 4.
• Auth.js with email and password, email verification and password reset, and optional Google sign-in; rate limiting and per-app cookie names.
• Private storage served through an access-checked file route with HTTP Range support.
• A read-only demo mode, one-click demo accounts and a guarded demo seed with bundled sample reels, presenters and voices.

What's in the package

• Full TypeScript source of the web app, the media engine and the render worker, .env.example, README and HTML documentation (including the deployment guide).
• The demo media under storage/demo/: 8 preset presenters, 6 sample reels with covers, and the sample projects' recorded voices.
• A demo seeder (plans, settings, demo logins, 16 demo customers, a month of payments and 7 sample projects) and the test suite (npm run verify).

Requirements

• Node.js 24 and npm, and MongoDB as a replica set (the credit ledger uses transactions)
• A server with ffmpeg and ffprobe for the render worker, plus Python 3 for the free neural voices. Rendering is a long-running job, so it does not run on serverless hosting; the web app alone can.
• Your own AI API key for scripts, images, premium voices and AI presenters
• Your own Stripe keys for live billing (simulated billing is used until they are set); optional SMTP and Google sign-in
