The “saving felt like understanding” line lands. That’s exactly where most read-it-later and summary tools break for me: they reduce the backlog, but they don’t preserve the user’s actual thinking.

One workflow I’d want is a clean distinction between source claims, AI outline, and my own interpretation/questions. If I edit the outline into my take, I’d want Gistr to remember “this is Jim’s synthesis” vs. “this was in the source,” so future AI help doesn’t flatten it back into a generic summary.

Do you keep the original transcripts and PDFs searchable offline, or is it all cloud based?

Congrats on the launch @arunfromgistr 🎉 I keep hearing nothing but good things about Gistr. A couple of my cousins are med students and they've worked it right into their daily routine, and the PMs I work with are big fans too. Excited to see where you take this.

Really like the positioning here...not just summarize this for me, but help me actually understand and work with the source material.

Time passes so fast but today, every minute feels worth it.
To everyone who upvoted, commented, and shared thank you.

Congrats on the launch team Gistr. Tried Gistr a couple weeks ago and the thing that surprised me was how fast the source got processed. Dropped in a 45-minute podcast expecting to wait, came back one minute later and the highlights were ready. Small detail but the speed of that step is what made me actually keep using it rather than closing the tab and forgetting.

One thing we kept noticing while building Gistr — learning online is weirdly fragmented.

PDFs are in one app, PPTs somewhere else, YouTube videos across 15 tabs, notes in another tool, and research chats sitting separately in ChatGPT.

Half the friction isn’t even learning — it’s just managing where everything is.

Gistr is our attempt at making all of that feel a lot more effortless. Your sources, notes, highlights, voice thoughts, and AI conversations all stay connected in one place instead of being scattered everywhere.

Would love to know if others here feel the same chaos while learning/researching online.

A thing I've come to believe building Gistr: the entire "save it for later" category has been broken for years.

We save things to feel productive. Then we never go back.

The tools that exist mostly help us save more efficiently. That's the wrong problem.

The actual problem is this:

Consumption and retention got disconnected somewhere along the way.

You consume something. You feel like you understood it. The act of saving it gives you a second hit of "yes, I'll come back to this." And then... you don't 🫠

Gistr is our attempt to reconnect the two. Not save more. Retain more.

Curious how others think about this. What's your take? 👇

Really excited to finally share Gistr with the Product Hunt community

Would genuinely love your feedback, questions, and even critiques. We’ll be around all day 👀

Hey Product Hunt 👋 - Arun here, founder of Gistr.

I used to screenshot content, save articles, and bookmark videos, convinced that future myself would handle it. But future me never did. Eventually, I stopped pretending the current system worked and began creating a different one.

The issue wasn't that I was saving the wrong things; it was that saving felt like understanding, which isn't the case.

Gistr aims to bridge that gap. It's not about quicker summaries of what you consume—it's a method to genuinely make sense of the sources you gather.

So we built it as a thinking companion, not a notebook or a summariser:

• 📥 Save and consume anything - YouTube, podcasts(Apple & Spotify), PDFs, articles, EPub, MOBI, PPTx, etc - via web, mobile, or browser extension

• 🎙️ Take notes your way - type, highlight, or record a voice note directly on any source. Your thinking lives next to the content that sparked it

• 💫 AI-generated outlines that you can customize and develop your own ideas from.

• 📍 Every AI response is grounded in your sources with citations you can verify.

• 🌳 A living knowledge base that gets sharper about you the more you use it (the part we're most excited about)

Who it's for: Lifelong Learners, Researchers, Curators, Content Creators, PMs, founders, and serious learners who consume a lot and want it to compound into real expertise - not a graveyard of saved URLs.

We're at 20,000+ users across 100+ countries, grown entirely through word of mouth. Today, we're bringing it to the PH community.

The free tier gives you the full experience. Explorer and Thinker tiers for power users, plus credit passes if you want to go deep on a project without committing.

Launch-day offer: 35% off the Explorer and Thinker tiers for the next few days. No code needed - discount applied at checkout.

I'll be here all day. Roast it, question it, tell me what sucks.

Most curious to hear: what's your current system for actually retaining what you read or watch? Mine was "hope" — which is how I ended up building this.
