Spine Research - Iterative deep research you control

Hey Product Hunt! 👋

We’re super excited to introduce Spine Research — the world’s first iterative deep research tool that puts you, the human, in the driver’s seat!

Deep research, when it works, is pretty cool — using an LLM’s multi-step reasoning to scour the web and find niche information that would normally take a human ages to uncover.

But what if it misses the mark? Most deep research tools out there are a black box; you don’t really know why it’s doing what it’s doing. Your only guidance is through a chat message — which is often the wrong UX for a multi-step process.

And if you want to iteratively build on your initial research? Maybe the AI went down the wrong path, or you want to add another section based on what you learned (research is fundamentally iterative — one-shot impressiveness only goes so far). You’re usually stuck going back and forth in chat.

Spine Research tackles all this.

• 📝 Start with your prompt, and Spine gives you a research outline of what it’s going to look for. You can edit and modify this as you like.

• 📚Once you’re happy with the outline, Spine generates an initial report – complete with references and sources – all in an easy-to-use, editable report format (because research should be collaborative between human and machine!). Spine often sifts through thousands of sources for your initial report, a magnitude more than other tools.

• 🪄 The real magic: Spine lets you iteratively enhance or add to sections of the report. Maybe you want to add a few more competitors for your diligence report, or include a new section on the side effects of a competing drug for your Ozempic report. Simply select the text you want to enhance and tell Spine what to do.

You control it all:

• Choose web research or your own documents.

• Scope to recent information, a specific category (research papers, financial documents, etc.), or even a specific domain.

• Select your preferred LLM — we default to Claude, but if you like OpenAI or Gemini models, we’ve got those for you too!

With Spine, you end up with a complete report giving you a deep understanding of your topic, all through a transparent process you’ve guided from the start.

With Spine Research, you can quickly:

• ⚡Analyze the impact of breaking news, market events, or regulatory changes on any company, industry, or investment.

• 🏢 Generate deep-dive company profiles for investment analysis, competitive intelligence, or account research.

• 📈 Build comprehensive market research reports to understand trends, opportunities, and customer needs.

• 📚 Conduct thorough literature reviews for medical, scientific, or academic purposes.

• 🔄 Iteratively refine ALL of the above with unparalleled control over sources and AI models, ensuring reports you can actually use.

If you use deep research tools daily, we’d love your feedback! Try our platform and see if this new paradigm resonates better than existing tools.

Thrilled to share what we’ve been building at Spine Research with the broader community! 🎉

Fast, flexible, and reliable deep research—whether you're analyzing a new market, evaluating an investment, preparing for a sales meeting, or conducting academic research, we’d love for you to give it a try.

Huge shoutout to the incredible Spine team for pushing this forward—we’re just getting started.

Excited to hear how you use it in your workflow—and how we can make it even better for you.

Been heads down with the amazing @Spine Research team building the next-gen deep research platform. Of all the capabilities it offers today, two stand out to me: giving users full control to create reports with language models while keeping humans in the loop, and enabling control over inference-time compute using the research depth param (fast, standard, deep) — a critical lever for guiding and scaling complex research workflows by adjusting how much reasoning and source exploration the model performs.

This is an incredibly powerful tool for anyone who spends hours gathering and synthesizing research. Giving users control over sources while still harnessing AI for speed and iteration is the perfect balance.

The ability to guide the process from start to finish, while still leveraging the power of LLMs, is exactly what the industry needs. I love that you can iterate on your report and refine sections as you uncover more data. Can you customize the AI's reasoning or provide additional context to help steer it more accurately during the research process?

As an engineer, I am inclined towards tight feedback loops.

They drive faster learning and better decisions.

But most AI research tools break that loop.

You ask a solid question → wait 10+ minutes → get a vague overview with no depth, no sources, no control.

Change your angle? Start over. No memory. No iteration.

We built Spine Research to fix that.

• Pulls from 3x more sources than anything we’d seen

• Focuses on exactly what you need news, papers, internal docs

• Lets you steer: adjust scope, exclude noise, dive deeper

• And you can layer in your own thinking notes, edits, links right in the doc

We didn’t want another summarizer.

We wanted a research engine that fits how thinking actually happens: iterative, contextual, hands-on.

That’s the magic of Spine:

It’s not just output. It’s a workflow.

We’re a small engineering team building the tool we always wished existed.

The internet already has the answers—Spine Research just helps you use them effectively. 🚀

Congrats on the launch! 🎉

Really like the angle of iterative research you control, hitting that sweet spot between automation and human direction is no small feat.

Excited to see how people start integrating this into their deep work flows. Rooting for you! 🚀

So many tools just generate generic summaries, but this one lets me go deeper. I can include technical documents or specific studies, then shape the AI’s focus from there. Super useful.

The most exciting part of working on this product for me has been the opportunity to rethink how users can interact with AI, beyond just a chat. For some of the fastest growing products in history, there so much that we’re still just scratching the surface of. So excited for all the new things we have planned going forward, to really help realize the promise of AI for users.

Looks interesting! just curious, how's the performance compare to chatGPT deep research @ashwin_raman

Really cool to see the different shape tools can take!

Great work team!

This is promising! Congratulations on the launch! Looking forward to exploring Spine in greater depth!

Wow! Just used Spline to for a quick research and boy! The result is detailed and gives me exactly what I was looking out for. The inline referencing is very helpful. Great job guys!
