Uptube.io is an 6 AI agents system that analyzes any YouTube channel generate ideas and writes scripts in the creator's own voice

A few months ago I started noticing something. Established YouTubers with 100K+ subscribers were paying 4-6 person research teams $8k-15k/month, and the scripts that came out still sounded generic. Not bad, just... AI-flavored. Like nobody specific wrote them.

That gap is what I'm building UpTube.io to close.

The core idea: paste a YouTube channel URL, and an AI agent does what a research team does but actually understands the channel first.

How it works under the hood

Instead of hardcoding "if news channel, search news" type logic, I gave the agent 5 generic tools (web search, fetch channel data, fetch transcripts, fetch comments, fetch any URL) and let it decide what to do with them. A finance channel and a cooking channel get completely different research paths, the agent figures it out from the channel's own content.

The part I'm most proud of: it reads video transcripts and learns how the creator actually talks vocabulary, pacing, hook style before writing anything. The goal is that when a creator reads the script, it sounds like their own best video, not a template with their name swapped in.

The model routing problem

Wanted Claude-level quality without Claude-level cost across every tier, so I built a provider-agnostic adapter - same agent, same tools, but the model swaps based on plan. Took longer to build than I expected, but it means I can swap any model in or out later without touching the agent logic.

Where I'm at

Building this from Cheyene,WY targeting primarily US/global creators. Backend is Next.js AI is Anthropic + OpenAI . Credit-based usage system so heavy users don't quietly drain margins on a flat subscription.

Free tier is live, no credit card required. I'd genuinely love feedback from anyone who's used AI script tools before and been unimpressed - that's exactly the bar I'm trying to clear.

uptube.io if you want to try it. Happy to answer anything about the agent architecture, the niche-detection logic, or the cost-per-tier math - building all of it in public from here.
