If you're looking for a Chrome extension to transcribe YouTube videos, you've probably come across both Claras and Scripsy.ai. They look similar on the surface — both are MV3 Chrome extensions, both offer AI-powered transcription and summaries, and both have freemium pricing.

But once you dig in, the differences matter. We put them side by side so you can make the right call.

Quick Overview

Claras is a Chrome extension that gives you one-click YouTube transcription with AI-powered summaries, key takeaways, chapter breakdowns, and highlights. It works on videos with or without YouTube captions, using its own AI transcription engine when needed.

Scripsy.ai is a Chrome extension focused on YouTube transcription and AI summaries. It offers fast transcript extraction with timestamps and AI-generated summaries on paid tiers.

Feature Comparison

Transcription

Both extensions extract YouTube transcripts quickly. Scripsy claims under-1-second transcription speed, which is fast — though in practice, both tools deliver transcripts near-instantly for videos that already have YouTube captions.

Where Claras pulls ahead: it can transcribe videos that don't have YouTube captions using its own AI speech recognition. Scripsy relies on YouTube's existing auto-generated captions. If a video has captions disabled or none available, Scripsy won't be able to help — Claras will.

AI Summaries

Both tools offer AI summaries, but the depth is different.

Claras gives you a structured analysis: a concise summary, bullet-point key takeaways, chapter-by-chapter breakdowns, and highlights — all generated from the full transcript. You get the "what was said" and the "what matters" in one view.

Scripsy provides AI summaries with key takeaways. The output is solid but less structured — you get a summary paragraph and key points, but no chapter breakdowns or highlight extraction.

User Interface

Both extensions display results in a sidebar on YouTube. Claras has a cleaner layout with clear separation between transcript, summary, and key points. Scripsy's interface is functional but more compact, which can feel cluttered on longer videos.

Pricing Comparison

Claras:

• Free: 7 day free trial and then 2 video/day forever + unlimited transcripts

• Starter: paid monthly plan with unlimited analyses

• Yearly: discounted annual plan

• Lifetime: one-time payment, unlimited forever

Scripsy.ai:

• Free: unlimited transcriptions + 1 AI summary/day

• Monthly: $8.99/mo — unlimited everything

• Yearly: $49.99/yr (~$4.16/mo)

• Lifetime: $79 one-time

Verdict on pricing: Scripsy's free tier is more generous for basic transcription (unlimited transcripts vs. 2 analyses). However, Claras's free tier includes the full AI analysis experience — summary, key takeaways, and chapter breakdowns — not just a raw transcript. If you only need plain transcripts, Scripsy's free tier wins on volume. If you want the AI insights, Claras gives you the full picture even on the free plan.

Where Claras Wins

• Works without YouTube captions — Claras can transcribe videos that have no subtitles using AI. Scripsy cannot.

• Deeper AI analysis — Chapter breakdowns, highlights, and structured key takeaways vs. basic summaries

• Cleaner interface — Better organized sidebar with clear sections for transcript, summary, and insights

• Full analysis on free tier — You get the complete AI experience, not just a raw transcript
  
  

Where Scripsy Wins

• More generous free transcription — Unlimited basic transcripts for free, with 1 AI summary per day

• Lower lifetime price — $79 lifetime vs. Claras's lifetime tier

• Multi-language support — Solid multi-language transcription on the free tier
  
  

Who Should Pick Which?

Choose Claras if:

• You want AI-powered insights, not just a raw transcript

• You're a student, researcher, or content creator who needs structured takeaways

• You value a quick, and well-organized answers

Choose Scripsy if:

• You mainly need raw transcripts in bulk and don't need AI analysis

• Budget is your top priority and you want unlimited free transcripts

• You want the cheapest lifetime deal available

The Bottom Line

Scripsy.ai is a solid, affordable transcription extension — especially if you just need the text. But if you want to actually understand the video, not just read it, Claras delivers more. The AI summaries are deeper, the chapter breakdowns save real time, and the ability to transcribe videos without captions is a feature Scripsy simply doesn't have.

For most users who want more than a copy-paste transcript, Claras is the better choice.
