Customer Reviews

“I don't have time to read 20 analyst reports a week. openbook's AI gives me the key insights in minutes, in plain English. It feels like having an investing co-pilot sitting next to me, which no other app has ever delivered.”

Grant

Private Investor

“Every other platform I tried felt like it was built for professionals. openbook is the first one that actually makes sense to me. The AI explanations are clear and I finally feel confident making decisions without second-guessing myself.”

Josh

Private Investor

“I used to spend hours jumping between spreadsheets and random stock blogs. Now I just open openbook. The screener finds opportunities I would never spot on my own, and the portfolio analytics show me exactly what's driving my returns. Total game changer.”

Sam

New Investor

Clear stock research without the noise

openbook cuts straight to what matters. I can scan a company, understand the factor scores, and know where to dig deeper without bouncing between five different sites.

Kieran

United Kingdom

Simple enough to use every week

The layout is straightforward and the explanations are written like a person. I use it to review ideas quickly before I spend time on the full annual reports.

Sarah

United Kingdom

Portfolio view is genuinely useful

What stands out for me is the portfolio breakdown. It shows concentration and factor exposure in a way that is quick to grasp instead of burying everything in spreadsheets.

Henry

United Kingdom

Fast way to filter ideas

The screener gets me to a shortlist much faster than my old process. I like that the same framework carries through into each stock page instead of changing from screen to screen.

Rob

United Kingdom

Finally written in plain English

A lot of investing tools assume you already know the jargon. This one does a much better job of explaining what changed, why it changed, and whether it is worth paying attention to.

Ivanna

United Kingdom

Easy to understand the score drivers

The best part is not just the headline score. It is being able to see the actual drivers behind it, which makes the whole process feel much more transparent.

Michael

United Kingdom

Good balance of speed and detail

I can get a quick read in a couple of minutes, but there is still enough underneath to keep digging. That balance is what makes me keep coming back to it.

Mike

United Kingdom

Helps me stay consistent

What I like most is the consistency. Every stock is assessed the same way, so it is much easier to compare ideas fairly and not get distracted by market noise.

Craig

United Kingdom

Useful from the first session

I signed up expecting a learning curve and there really was not one. The search, the stock pages, and the portfolio checks all felt intuitive straight away.
