Inspiration

I wasted way too much cash on my first startup because I built it based on my gut, without checking if people actually wanted it. So when I started playing around with a new HR/recruiting app idea, I did the opposite—I dove deep into competitor reviews to find out what actual users were saying. Specifically, I looked at common pros and cons: what features users loved, what got them excited, and especially the gaps they complained about. It was super helpful, but it also took forever. I thought, “There has to be a quicker way to get these insights.” So during the Bolt.New hackathon, we built Review BI, a simple tool that pulls those key insights straight from user reviews.

How we built it

We built our project using Bolt.New in combination with Supabase. The app is deployed on Netlify. Integration with GitHub allows us to know that we’re now proudly approaching 200 commits!

Challenges we ran into

At the beginning, we weren’t entirely sure whether we’d be able to create beautiful multi-layered graphs with smooth animations — which were core to our concept. While we managed that part well, we underestimated the effort needed to build polished micro-animations for certain other interface elements. That part turned out to be trickier than expected :)

Accomplishments that we're proud of

Our peers praised the visual appeal of the dashboard and how intuitive the charts are to use. We’re especially proud of transitioning from a basic architecture — where each query hit the database directly — to a much more efficient in-memory computation model. Bolt.New made this transition remarkably smooth. Now, our charts feel almost instant in response — something we’re genuinely excited about!

What we learned

We were pleasantly surprised by several aspects of Bolt.New:

Its flexibility in handling complex chart types, including unconventional ones (like selectively filling segments in a TreeMap chart);
The successful transition to a completely new in-memory computation architecture (with just a few reminders needed to restore lost logic);
The experimental Diffs feature — it worked brilliantly and, most importantly, saved us a lot of time, speeding up development even more. Magic!
The high quality of default UI elements generated by Bolt.New, as well as its uncanny ability to pick up design nuances based on screenshot references. Regarding Bolt.New’s methodology in general:
Our biggest insight was that when adding a complex new feature, the process and outcome improved significantly by ending the prompt with something like:
“Please don’t code anything until you’re 95% confident I really want this implemented. Ask questions if needed.”
This reliably led to a thoughtful series of 3–6 questions instead of a rushed and sometimes unexpected implementation. Answering those questions almost always resulted in exactly the solution we envisioned.

What's next for Review BI

We’re aiming to take the product to market. Here’s what’s next:

Create a more convenient data upload flow for new projects;
Launch pro plans with premium features, such as:
Comparing multiple products within a single dashboard;
Event tracking and client notifications;
A suite of AI-based interpretation tools for insights from existing data;
Expand our use cases beyond competitive analysis for startups to include active reputation monitoring for existing products and benchmarking against competitors’ evolving performance.
