Show HN: Wordspike–AI spikes from any YouTube video (multilang, Kindle export)

1 thekuanysh 1 9/15/2025, 1:15:22 PM wordspike.com ↗
Kuan here, solo dev. I was sinking hours into YouTube “learning” videos—one leads to five, killing deep work focus. My solution: Pull the core (summaries, insights, action steps) and skip the rest.

Launched Wordspike this week: Paste a YouTube URL (web app or browser extension), and it generates structured text output right away.

Key features:

- “Spikes”: AI-generated summary + key ideas + insights + actionable steps (minimalist, no fluff). - Multilingual: Handles non-English videos natively (e.g., I’m extracting from Chinese tech talks as I don’t understand Chinese). - Exports: PDF/EPUB, or sent directly to Kindle in ~90 seconds.

Tech: End-to-end with Bun/JS backend, Redis for async processing, minimalist UI. No team or funding—just bootstrapping *to solve my own problem*.

Early traction: 20+ users in 4 days; strong feedback on trials.

Try it: https://wordspike.com (freemium, just paste a YouTube URL to test).

Curious: What features would hook you? Tech thoughts on multilingual LLM handling or async scaling?

Happy to discuss stack, async workers, or non-English LLM tweaks.

How do you manage video overload in your workflow?

Hey HN, I'm the creator of Wordspike.

I built this because I have a love-hate relationship with YouTube. It's an incredible resource, but the platform's design makes it a major productivity trap. I wanted a way to get the knowledge without the time sink.

Wordspike takes any YouTube link and turns it into a clean, readable article with summaries and key insights. It also has a one-click "Send to Kindle" feature. I built the first version in about two weeks using React, Bun, Postgres, and Redis.

The site is live at: https://wordspike.com

I would be grateful for any and all feedback from the HN community—on the product, the tech, the business model, anything.

As a thank you, I'd be happy to set up anyone from HN with a promo Pro account. Just leave a comment here or my email is in my profile.

Thanks for checking it out!
