Client collaboration platform made for professional services
Ok, ok maybe just behind Notion but it's definitely among the top options. Excellent software whether you need a simple note-taking tool or something more robust. Fusebase is my preferred app for managing projects, and regardless of your needs you won't be let down. My only complaint is the absence of a mobile app. The older Nimbus app handles basic tasks, but a full featured mobile version would be amazing. Don't hesitate — get it now!
I have been debating about this product for some time now but with recent reviews and research decided to buy it.
Long time eernote and notion user so looking forward to enhanced capabilities.
There are many client portal platforms in the market, but very few manage to strike the right balance between functionality, security, flexibility, and cost. Many platforms are either too marketing-focused, lack meaningful design flexibility, fall short on security controls, or are simply overpriced. And in practice, building a portal that actually makes sense to clients—one that is intuitive, organized, and adaptable to different workflows—is often the hardest part.
Fusebase stands out because it addresses all of these challenges thoughtfully. Their platform combines strong security measures (SOC 2, MFA, and more) with a high degree of customization in structure and configuration. It’s clear that their roots in knowledge and content management influenced the product in the right ways—making it easier not just to store information, but to distribute and present it effectively to clients.
Another key differentiator is reliability. Fusebase has been around for years, which matters in a landscape where new SaaS platforms appear and disappear quickly. Their support has also been excellent—responsive within the same day, even during the high-demand period of their AppSumo campaign.
The development roadmap is active and meaningful, with updates that actually improve usability. I’ve suggested features that may not have been widely requested at the time, and the team not only considered them but incorporated several into their development plan—with some already released. The new AI agent and automation capabilities further elevate the platform, reducing manual workload and enabling smarter client delivery.
I’m genuinely looking forward to seeing where the team takes this next. Fusebase is shaping up to be a serious long-term solution in the client collaboration and knowledge-sharing space, and I wish the team continued growth and success. They’ve built something with real substance—and it shows.
FuseBase isn’t Notion... and that’s a good thing. It keeps the essentials that teams actually use and drops the extras most people don’t need.
It’s not Humata... but it brings practical AI assistants your team and clients will actually rely on.
It’s not a portal builder... yet it’s simple, no‑nonsense and remarkably flexible.
It’s hard to describe, maybe because it’s inventing a new category: a smoother way to work that keeps everyone in one place without constant app switching, lost context, or unnecessary stress.
As I said: Fewer handoffs, clearer client collaboration, and AI that gets things done (not just talks) ;))
I've been following the development from 2021 and it's been a treat. This time around I advise to buy the full stack for what it offers an all in one ultimate work hub. The mobile apps are needed though to make this complete
The only thing for which this deal would have been a five tacos for me is evernote imports.
i had used evernote around 10 years since beginning and have around 9000+ notes in it.
Providing seamless import from there to specific notebooks of nimbus is great tool in itself.
Plus 50GB space, plus automations, AI integrations, notion like notes. and many more things down the line as the app progresses.
one more thing, chrome extensions are also awesome. I have used nimbusnotes in the past, and it worked great.
good luck to the team for great success ahead. And thank you for providing the deal on Appsumo.
I have a lot of Codes and the features of Fusebase are great. I mostly still take it for notes, created my first automations - and love them.
Instead of only focusing on AI features I would like to see an optimization of performance and - most important - the editor. It would be great if it was possible to export to Markdown and be more compatible with it, since this is very popular and high demanded these days.
For example I often copy & paste Markdown content into the editor and have a lot to fix, and I run an automation which outputs Markdown and want to automatically create a page. Creating the page works flawlessly, but not without editing the output (code blocks for example, only to name one)
All in all: Still a great tool, don't want to miss it.
One Pinned tab on my browser is always Fusebase.

I am very happy that I have become more productive and organized with Fusebase. (I still love to call it nimbus note)
In contrast to certain AppSumo deals that seem neglected by their developers, Fusebase consistently enhances and invests in their product. I purchased this deal when it was Nimbus Note in 20-21, and was excited by what the product offered then: a place to take notes, capture videos, etc.
FuseBase represents the next generation-which is both exciting and a bit confusing. This advancement is impressive but may require some time to learn how to use effectively. Fortunately, users can sign up for walkthrough support, which is readily available and now on me to schedule and do the thing. I’ve recently added a new code, and their customer service has been great in addressing my questions. I’m excited to explore this product further, as it was already impressive and now boasts even more powerful features, even if I don't yet understand them.
I just saw a recent 1 star review from someone and I immediately thought that is crazy, could not be further from the truth. This is one of the top ten Appsumo deals of ALL TIME. The AI and functionality is firing on all cylinders! There is a LEARNING CURVE, but if you get past it like most people do, then this is a very serious product with a real set of recipes to organize and scale your business. Literally, hardly ever see a product on here that is this complete. I love it, i loaded up on some codes and we are rocking with Fusebase. Keep up the great work Fusebase!!
I'm not sure how this product is getting anything past a two star unless they are paying for it but it has plenty of shortcomings.
1. Very insecure. I would not put any confidential documentation on this app. (Anyone can resuse the same browser session and steal important information)
2. Not user friendly at all. (Not challenging to use just not intuitive)
3. Limited customization options. (Can not customize the login page at all. Unable to delete certains items.)
4. Poorly written documentation. ( The documention does not address all features.)
5. Not all advertised functionality is there.
I have to be honest in my reviews.
This product has solved a whole stack of documentation, workflow, resource, and file sharing pain points in my business. I was a NimbusNote user 5 years ago. I liked it but it was slow, so I never got much use out of it. Fusebase builds on that original superdocs concept, but steps it up 100x. This product is elite tier, and this dev group is dedicated long-term. If you have multiple workflows to coordinate across a team of 10-15+... stack 10 codes and get to work. You'll never look back.
