Hacker News

Creating short-form vertical videos from Reddit posts requires manual scraping, editing, and voiceover work that takes hours per video and does not scale for creators posting daily.

What is it?

Thousands of faceless content creators are printing money repurposing Reddit posts as TikTok and YouTube Shorts videos — but the manual pipeline is brutal and doesn't scale. ReelRaft auto-scrapes top posts from a chosen subreddit, generates a voiceover script, synthesizes realistic speech via ElevenLabs, overlays text-on-screen captions synced to the audio, adds a blurred background or stock footage layer, and exports a 9:16 MP4 ready to upload. Target niche at launch: r/AmItheAsshole and r/tifu — proven virality, high text volume, massive creator audience. Buildable right now because Reddit API (public read), ElevenLabs TTS, and FFmpeg-based video composition via Remotion are all stable and accessible without enterprise contracts.

Why now?

Remotion Lambda made serverless video rendering affordable in 2024, ElevenLabs dropped API prices, and the Reddit-to-TikTok faceless creator niche is exploding in April 2026 with creators openly complaining about the manual grind on Twitter/X.

  • Subreddit post browser with virality score filter (upvote ratio + comment velocity ranking)
  • AI voiceover generation via ElevenLabs with 6 pre-set voices optimized for storytelling
  • Auto-synced word-by-word caption overlay rendered via Remotion at 1080x1920
  • One-click MP4 export with background blur + stock footage layer from Pexels API

Target Audience

Faceless TikTok and YouTube Shorts creators in the Reddit drama niche — estimated 500k+ active creators doing this manually.

Example Use Case

Marco runs 3 faceless TikTok accounts in the AITA niche, uses ReelRaft to produce 10 videos per day instead of 2, grows from 50k to 300k followers in 6 weeks, and monetizes via TikTok Creator Fund and brand deals.

User Stories

  • As a faceless TikTok creator, I want to turn a Reddit post into a voiceover video in under 5 minutes, so that I can post 10 videos per day instead of 2.
  • As a YouTube Shorts creator, I want to browse top posts by virality score, so that I only spend time on content likely to get traction.
  • As a Pro subscriber, I want to choose from 6 distinct AI voices, so that my different channel personas sound unique.

Done When

  • Post browser: done when user selects a subreddit and sees top 20 posts ranked by upvote ratio with title preview within 3 seconds.
  • Voiceover: done when user picks a voice, clicks generate, and hears a preview of the AI audio in under 20 seconds.
  • Video render: done when user clicks Render and receives a downloadable 1080x1920 MP4 with synced captions within 4 minutes.
  • Paywall: done when free user hits 5-video limit, sees upgrade prompt, pays via Stripe, and their credit count resets immediately.

Is it worth building?

$39/month x 100 creators = $3,900 MRR at month 3. Assumes 5% conversion from ProductHunt and TikTok creator communities with 2,000 free signups.

Unit Economics

CAC: $8 via creator DMs and Reddit posts. LTV: $468 (12 months at $39/month). Payback: under 1 month. Gross margin: 62% after ElevenLabs and Remotion costs.

What's the competition?

Competition Level

Medium

Similar Products

CapCut for manual editing (no automation), Opus Clip for long-form video clips (not Reddit-native), Vidyo.ai for repurposing (no Reddit scraping or TTS) — none offer a Reddit-to-vertical-video pipeline with AI voiceover.

Competitive Advantage

Remotion-based rendering is 10x cheaper than cloud video editors. Reddit-native post browser saves 20 minutes of manual scraping per session.

Regulatory Risks

Reddit ToS allows public post reading for personal use but rate-limits scraping — use official Reddit API with OAuth. ElevenLabs voice cloning requires consent compliance. Low regulatory risk overall.

What's the roadmap?

Feature Roadmap

V1 (launch): Reddit post browser, ElevenLabs TTS, Remotion render, MP4 download. V2 (month 2-3): YouTube Shorts export, voice preview, caption style picker. V3 (month 4+): direct TikTok upload, bulk scheduling, custom voice cloning.

Milestone Plan

Phase 1 (Week 1-2): Reddit fetch, ElevenLabs voiceover, and Remotion template render working end-to-end. Phase 2 (Week 3-4): Stripe billing, R2 storage, full dashboard UI live. Phase 3 (Month 2): 30 paying creators with 80% weekly active usage.

How do you build it?

Tech Stack

Next.js, Reddit API, ElevenLabs API, Remotion for video rendering, Supabase, Stripe, Vercel — build with Cursor for pipeline, v0 for dashboard UI

Suggested Frameworks

Remotion, ElevenLabs SDK, FFmpeg via Remotion Lambda

Time to Ship

3 weeks

Required Skills

Reddit API, ElevenLabs TTS, Remotion video rendering, FFmpeg, Stripe, Next.js.

Resources

Remotion docs, ElevenLabs API docs, Reddit API docs, Stripe billing docs.

MVP Scope

app/page.tsx (landing), app/dashboard/page.tsx (post browser + generator), app/api/reddit/route.ts (post fetch), app/api/voiceover/route.ts (ElevenLabs), app/api/render/route.ts (Remotion Lambda trigger), app/api/stripe/route.ts (billing), remotion/VideoTemplate.tsx (9:16 video composition), lib/db/schema.ts (schema), components/PostCard.tsx (post selector), .env.example

Core User Journey

Pick subreddit -> browse top posts -> select post -> choose voice -> click render -> download MP4 in 3 minutes -> upgrade when credits run out.

Architecture Pattern

User selects Reddit post -> Reddit API fetches content -> ElevenLabs generates MP3 -> Remotion Lambda renders 9:16 video with captions -> R2 stores MP4 -> download link delivered via Supabase realtime.

Data Model

User has many VideoJobs. VideoJob has one RedditPost, one Voiceover, one RenderedVideo. RedditPost belongs to one Subreddit.

Integration Points

Reddit API for post data, ElevenLabs for TTS voiceover, Remotion Lambda for video rendering, Pexels API for background footage, Supabase for user data, Cloudflare R2 for video storage, Stripe for billing.

V1 Scope Boundaries

V1 excludes: direct TikTok upload, voice cloning, team accounts, scheduling, multi-platform export beyond MP4.

Success Definition

A faceless TikTok creator finds ReelRaft via Twitter/X, generates a real video from a Reddit post without any founder help, posts it, and upgrades to Pro before the free limit runs out.

Challenges

ElevenLabs API costs scale fast at volume — at $0.003/character and 1,500-character posts, 60 videos/month = ~$270 in API costs for one Pro user, which destroys margins unless usage is capped hard.

Avoid These Pitfalls

ElevenLabs costs will eat your margins before you notice — implement hard per-user character caps from day one. Do not build a custom video editor in v1, Remotion templates are enough. Finding first 10 paying creators takes longer than building — budget 3x more time DMing creators than writing code.

Security Requirements

Supabase Auth with Google OAuth, RLS on all user tables, signed R2 URLs for video access, rate limiting 30 renders/hour per user, input sanitization on Reddit post text before TTS.

Infrastructure Plan

Vercel for Next.js, Supabase for Postgres and auth, Remotion Lambda for rendering, Cloudflare R2 for MP4 storage, GitHub Actions for CI/CD, Sentry for errors — total infra ~$215/month.

Performance Targets

200 DAU at launch, video render under 4 minutes, dashboard load under 2s, R2 CDN for video downloads.

Go-Live Checklist

  • Security audit complete.
  • Payment and credit flow tested end-to-end.
  • Sentry error tracking live.
  • Remotion Lambda warm-start tested.
  • Custom domain with SSL configured.
  • Privacy policy and terms published.
  • 10 beta creators tested and gave feedback.
  • Rollback plan for Remotion Lambda documented.
  • ProductHunt and creator subreddit launch posts drafted.

First Run Experience

On first run: sample AITA post pre-loaded in the post browser with a generated voiceover and rendered demo video ready to play. User can immediately watch the demo video and download it without connecting any account. No manual config required: demo video plays instantly, Reddit API only needed for real post browsing.

How to build it, step by step

1. Define schema in lib/db/schema.ts: User, Subreddit, RedditPost, VideoJob, RenderedVideo. 2. Run npx create-next-app with TypeScript and Tailwind. 3. Install @remotion/lambda, elevenlabs SDK, stripe, drizzle-orm, supabase-js. 4. Build Reddit API fetch route returning top posts with upvote ratio and title. 5. Build ElevenLabs voiceover route with 6 voice options and character count guard. 6. Build Remotion VideoTemplate.tsx composing background, waveform, word-synced captions at 1080x1920. 7. Deploy Remotion Lambda and wire render trigger to app/api/render/route.ts. 8. Store rendered MP4 in Cloudflare R2 and return signed download URL. 9. Add Stripe credits billing with hard usage cap enforcement. 10. Deploy to Vercel and walk full journey: select post, generate voice, render video, download MP4, hit pay wall.
