Meet Warren Avis 

Great tool - in-between building my own complicated spreadsheet and using a financial advisor. Can model different retirement dates and see how that impacts the plan. Recent changes to add other people but treat together really helpful. Gives me assurance I'm on track. I have used both the voice and type options to update the plan - like both options depending on what I'm trying to do.

I’m comfortable making my own financial decisions and plans, but I was looking for something that sits between fully DIY (using Excel or tools like ChatGPT) and paying for a financial adviser — something that could provide guidance and a second opinion. Warren is the only product I’ve found that genuinely attempts to fill that gap.
The experience feels much more like a conversation than completing a form. You’re asked about your goals, retirement plans, concerns, savings, pensions, and investments in plain English, and it works with you to build a plan that reflects your actual circumstances.
Warren quickly produces personalised forecasts and action plans. It handles more complex scenarios — such as bonuses, specific savings goals, or less typical financial situations — which gives it a level of flexibility beyond a standard templated approach.
I started using Warren in version 1, and it has evolved rapidly since then. Improvements have been consistent and clearly informed by user feedback, and notably, there has been no loss of data — no small feat in software development. I’ve also tested its outputs, using identical inputs, against advice from two financial advisers. In my experience, the quality is comparable, but Warren is significantly more accessible, available 24/7 via web or app, whereas speaking to an IFA can often be less convenient.
That said, it isn’t regulated and isn’t tied to any specific financial provider, so it’s best viewed as a coaching and planning tool rather than a substitute for regulated advice.
For transparency, I work in financial services as a Senior Director of Data and AI Solutions. I have no connection to the company behind Warren, but based on my experience, I would not hesitate to recommend it.

A really clever tool to help you plan. For me i was focused on retirement. A quick ‘call’ with AI and it had worked out my situation and built my plan. Team behind it are improving the UX all the time - its a great help if you need some guidance and a solid plan

Version 3.0 a real step up, and theres so much more they can do (and probably will do) to improve even further

MI’ve spent years looking for a tool that sits between “figure it all out yourself” and “pay for a financial adviser”.

In the UK there seems to be very little available for people who are comfortable making their own decisions but would still value guidance, structure and a second opinion along the way. Warren is the first product I’ve found that genuinely tries to solve that problem.

The experience feels much more like having a conversation than filling in forms. You can explain your goals, retirement plans, concerns, savings, pensions and investments in plain English, and the system works with you to build a plan that reflects your actual circumstances.

I particularly like the way it creates personalised forecasts and action plans. If your situation includes bonuses, specific savings goals or unusual circumstances, those can be reflected rather than forcing you into a generic template.

Another positive has been the pace of development. I’ve seen meaningful improvements introduced in a relatively short period of time, and the team appear to listen carefully to user feedback.

Importantly, Warren doesn’t present itself as regulated financial advice, and that’s an important distinction. What it does provide is a highly useful financial coaching and planning tool that helps people think more clearly about their options and organise their financial lives.

For anyone who enjoys taking an active interest in their finances but doesn’t necessarily want ongoing adviser fees, it’s well worth a look.

Version 3.0 is a huge improvement. It is has gone from being a pretty well trained AI to really providing great insight. If it could work with Open Banking then it would really be a game changer.

Since the release of 3.0 the app is so much better. I know the team worked super hard and it's very cool to see it pay off. I fed the same info to Warren as last time - MUCH better output, much smoother experience and way less bugs.

This seems like a good idea, and actually what I was looking for having been talking to general AI tools (chat gpt etc) about my financial planning. Two problems kept me from using this service: 1) on logging in I could see no statement about data handling or privacy. I am reluctant to hand over all my financial info without at least some idea how it will be used and protected. 2) the only available first step seemed to be to "have a call" with Warren. I am not particularly keen to talk to an AI I don't know why I can't fill in a webform with my info.

If you want your adviser to be a script with no ability to make compassionate and common sense recommadations, this is your app. I get that AI is clever enough to do this but I want someone in charge of my money to understand me. Warren isn't a financial adviser, it's an information aggregator. If you would use a decision tree to let an ai doctor prescribe the best pills for you this is your app, I prefer an accountable human.

Thanks for your AI reply. It's so obviously AI and anyone with any knowledge of how AI writes can spot it.

A great tool for financial planning. I thought the voice interface was a really nice touch too - just tell it what I want to do, and et voila!

After just a few minutes of chatting with Warren I had a financial plan and set of clear actions I can take to get on track. Whenever something about money comes to mind I give Warren a call to run it past him and see how it might impact my plans. This experience is so much more accessible, simple and faster than human led financial planning I have used before.
