Daily Idea - Letterboxd for Youtube Videos
Elevenlabs for your MVP

Your YouTube Content, Organized

Inspired by this tweet
The One Liner
Track, rate, and share YouTube videos.
The 140 character tweet (or X) version
Your YouTube experience, upgraded. Track what you watch, rate it, and share curated lists with friends—think Letterboxd, but for videos.
The Longer Story Version
The Problem
We’ve all been there: scrolling endlessly through YouTube. There’s too much content, and it’s easy to lose track of the gold buried under all the noise.
You watch a killer documentary, a life-changing tutorial, or a hilarious vlog. A few weeks later, you try to find it again—and… nada.
Sure, YouTube's algorithm helps a little, but it’s built for short-term views, not long-term curation. There’s no easy way to organize what you’ve seen or share it with others.
And forget about personalized recommendations outside of YouTube’s autoplay loop.
The Solution
A platform to log, review, and share your YouTube journey.
Here’s how it works:
Log it: Add any video you’ve watched.
Rate it: Loved it? Meh? Give it a score.
Review it: Jot down your thoughts—was it hilarious, insightful, or a waste of time?
Curate it: Build and share themed lists like "Best Sci-Fi Shorts" or "How to Start a Side Hustle."
Discover it: Get recommendations from people you trust, not just algorithms.
It’s like your personal archive of all the YouTube content that matters to you, plus a community vibe where you can see what your friends are watching and loving.
How We'd Build It
Tech Stack:
Use YouTube API to pull video data (title, thumbnail, etc.).
Leverage GPT-4 or another LLM for content tagging and sentiment analysis.
Next.js or React for the front end (fast, modern, and scalable).
Backend on Firebase or AWS Lambda for real-time updates.
PostgreSQL for structured data storage (user logs, reviews, lists).
Connect with Zapier to automate social sharing and cross-promotion.
Bonus Features:
Community forums for video discussion.
Integrated AI to recommend hidden gems based on user-curated lists.
Social media integrations for one-click sharing.
Why It Needs to Exist
Because YouTube is chaotic, and your time is valuable.
This tool isn’t just about tracking videos—it’s about turning passive watching into a richer, more meaningful experience. You’ll have the tools to organize your viewing habits, build your own recommendations, and connect with people who share your interests.
For creators, it’s a chance to reach superfans who actively engage with their content. For viewers, it’s a way to cut through the noise and find content that actually resonates.
If you’re tired of endless scrolling and want more control over your YouTube experience, this changes the game.

AI Voice Tech for the MVP

You ever listen to an AI voice and think, Wow, that’s robotic AF? Not anymore.
Meet ElevenLabs (not an advertiser yet) —the AI voice tech that doesn’t sound like a bad GPS. This thing generates voices so real, you’ll think they hired Morgan Freeman to narrate your life. It’s next-level, and for startups, it’s a game-changer.
What is ElevenLabs?
Think of ElevenLabs as the Drake of AI voiceovers—smooth, versatile, and always on point.
You give it some text, choose a voice (or clone your own if you’re feeling fancy), and boom—studio-quality audio in seconds. No more paying for voice actors, no recording studios, and definitely no endless editing sessions.
Let’s say you’re building a language-learning app. You need different characters to speak in various accents, tones, and moods. Normally, you'd hire multiple voice actors and spend weeks in post-production.
With ElevenLabs, you can:
Generate multiple voices instantly.
Tweak the tone—make it happy, serious, or anything in between.
Make changes on the fly.
Need a voice to read bedtime stories? Easy. Want something for a customer service bot? Done. You’ll save time, money, and a ton of headaches.
I swear not an advertiser - just that important to share.
How It Can Help Your MVP
Here’s a quick scenario:
Imagine you’re launching a personal finance app for Gen Z. You want a feature where users get daily motivational tips—delivered by a fun, relatable voice. You don’t have time (or budget) to hire a celebrity, so you use ElevenLabs to create the perfect AI voice.
You test out a few scripts, get early users to give feedback, and iterate in real-time. You’ve just saved months of work—and thousands of dollars—while getting your MVP out the door faster.
Other AI Tools to Supercharge Your MVP
ElevenLabs is a beast for AI voice, but let’s talk about some lesser-known AI tools that can give you an edge. These aren’t the usual suspects like ChatGPT or Canva—these are under-the-radar power-ups for your startup’s MVP.
1. Copy.ai (for Instant Marketing Copy)
Generates ad copy, landing page headlines, email scripts, and more. Optimized for marketing, it helps you get ready-to-test copy in minutes. You can write 10 tagline variations for A/B testing with just one prompt.
2. Runway ML (for AI-Powered Video Editing)
AI video creation and editing with features like background removal, text-to-video, and style transfer. No need for expensive video shoots—Runway lets you create marketing videos by simply typing prompts. Perfect for product explainer videos.
3. MidJourney (for Visual Design)
Generates stunning visuals from simple text prompts. Whether you need illustrations, product concepts, or custom graphics, MidJourney can deliver results that look like high-end designs. Great for landing page hero images or branding assets.
4. Motion (for AI-Powered Project Management)
Automates your schedule and task prioritization. Motion acts like a smart assistant, learning your work habits and updating your schedule in real-time. Ideal for managing multiple MVP sprints without spending hours updating calendars and task lists.
5. Durable (for Instant Website Creation)
Creates fully functional websites in under a minute. Just enter your business type, and Durable generates a ready-to-use site. It’s perfect for quickly launching a landing page to test your idea while you develop your core product.
Why Use AI for Your MVP?
Look, time is your most valuable currency when building a startup. You’re not here to perfect every little detail. You’re here to ship, test, and learn.
AI tools like ElevenLabs let you skip the expensive stuff—voice actors, editors, and dev cycles—so you can focus on what really matters: user feedback and iteration. Launch, adjust, repeat.
