PaperPod - Turn any document into an interactive AI podcast

by•
Upload PDFs, DOCX, notes or text and turn them into natural two-host AI podcast conversations. Listen while commuting, studying or working, then interrupt anytime to ask questions using document-only or document + web AI.

Hey Product Hunt! šŸ‘‹ I'm Pushkal, and I'm excited to share PaperPod. The idea came from a simple frustration: I had hundreds of PDFs, research papers, design docs, and notes that I wanted to read—but rarely finished. Traditional text-to-speech wasn't engaging enough. So I built PaperPod to transform documents into natural conversations between two AI hosts. The feature I'm most proud of is that you can interrupt the podcast anytime and ask questions. You can choose between: šŸ“„ Document Only (grounded in your uploaded file) 🌐 Document + Web (combines your document with current web knowledge) I'd really love feedback on: Is the podcast format more engaging than traditional summaries? What document types should PaperPod support next? Which integrations would you like to see (Google Docs, Confluence, Notion, Canvas LMS)? Thanks for checking it out—I’ll be around all day to answer questions!

Would love to see a way to export the transcript alongside audio playback, so I can quickly scan or search specific moments without having to scrub through.

Ā You can share, download podcast audio and transcript script with proper speaker diarization (Host, Guest). Also there is live transcript support when the podcast audio plays. You can click on any line to jump in the audio.

Just Click on Show Transcript

From UI's perspective should I make this more clear?

Love how the two-host format actually feels like a real conversation instead of a robotic Q&A loop, and being able to interrupt mid-episode to ask a follow-up is such a thoughtful touch.

Ā 

Thank you! That's exactly what I was aiming for.

My goal wasn't to build another TTS reader—it was to recreate the feeling of listening to a podcast where you can naturally pause and ask questions whenever something isn't clear.

If AI is going to change how we learn, I think conversations are a much better interface than static pages.

Would love to know what you'd listen to first—research papers, books, documentation, or something else?

The two-host format actually sounds like a real conversation instead of robotic narration, and being able to interrupt to ask follow-ups mid-listen is a really thoughtful touch for commute use.

Ā Thank you! Commute learning is actually one of the biggest use cases I had in mind.

There are so many documents we want to read but never find uninterrupted time for. My hope is that waiting in traffic, walking, or commuting can become productive learning time instead.


Is there a particular type of content you'd use it for during your commute?

Thank you so much!

I found that most AI readers still feel like robotic narration. I wanted PaperPod to feel more like listening to a discussion where you're free to interrupt, ask follow-up questions, and immediately continue the conversation.

I'm really happy that came across in your experience.

Thanks! 😊

That conversational feeling was one of the hardest parts to get right. We spent a lot of time refining the dialogue generation so it feels like two people genuinely explaining concepts instead of alternating paragraphs.

It's great to hear that it feels natural. That's exactly the experience I was hoping to create.

Genuinely useful for my long reading lists. Two-host format feels way more engaging than typical tts, and the interrupt-to-ask feature actually pulled correct details from the pdf I uploaded. Solid stuff.

Ā Really appreciate that, it means a lot coming from someone who actually tried it. :)

The biggest engineering challenge wasn't the AI itself, it was latency. I spent quite a bit of time optimizing the generation pipeline using adaptive concurrency, faster audio synthesis, smarter LLM routing, and retry mechanisms to get the total generation time close to a minute.

If you get a chance, I'd love for you to try it with something more challenging—a research paper or a document full of architecture diagrams—and let me know where it breaks. That's the kind of feedback I'm looking for.

The two-host format is a really smart touch, it keeps the listening experience from feeling like another dry TTS dump and actually holds attention. Love that you can jump in mid-conversation with a question too.

Ā 

Thank you! That was actually one of the core design goals.

Traditional text-to-speech often feels like someone reading paragraphs aloud. I wanted it to feel like you're listening to two people naturally explaining the material instead.

The interruption feature came from my own habit of constantly stopping while reading to ask "Wait... why does this work?"

Curious—what kind of documents would you personally use PaperPod for?

Would love a way to export the full transcript with timestamps, and maybe a highlights doc pulled from the conversation. Super helpful for studying or referencing back later without re-listening to the whole thing.

Ā 

That's an excellent suggestion.

The transcript already exists internally with speaker information, so adding timestamps and making it exportable is definitely feasible.

I also really like the idea of generating "conversation highlights" or key takeaways automatically after the podcast finishes. That would make revision much easier without replaying the entire episode.

Added to my roadmap. Thanks for the idea! šŸš€

The biggest latency improvements didn't come from changing models.
They came from engineering.

PaperPod now converts an 18-page research paper (including architecture diagrams, tables, and technical figures) into a 20-minute, custom two-host conversational AI podcast show within just ~80 seconds.

Behind the scenes:
- Prompt caching
- Lossless token reduction
- TPM-aware scheduling & retries
- Intelligent LLM routing
Production AI is a systems engineering problem disguised as an ML problem.
