Longtime user and fan
I have been using Nimbus (not Fusebase) since it was on Appsumo originally and it's like Evernote for those who don't want to be limited to 2 devices.

FuseBase is ambitious and capable
I bought it many years ago as NimbusNote. At that time, I was looking for a capable Evernote alternative, since their price kept climbing and their free features kept reducing. NimbusNote handled my bulk Evernote importing like a champ—truly impressive.
Since then, it's become FuseBase, which is a cooler name with more ambition, which I appreciate. Although this has been my most expensive LTD ever through all the upgrades, I'm confident in the team to continue delivering great value for years to come.
Their content AI is legit. Their database functionality is coming soon. Their Automations and AI Agents were unexpected but very appreciated.
Here's to cheering you on for many more!

One of the TOP tools that AppSumo has ever offered!
We at the agency have been using FuseBase (formerly Nimbus) since 2021. We rely on this platform daily and have moved all notes, file-sharing with clients, and the client portal to it. I value their support and their commitment to sharing knowledge through webinars. The tool has a lot to offer digital and tech professionals, as well as agencies like ours.

Easy Automation, Slick Portals - Great for Small Businesses
Fusebase is a super handy all-in-one platform for anyone running a business, working with clients, or needing a smart workspace. The standout for me is how easy it is to create slick client portals and manage everything—tasks, docs, forms, automations—without any hassle. Their AI tools are surprisingly good, helping keep your projects and communication organized and running smoothly.
Setup is quick, and you get a lot of customization, so you can really make it fit your brand. Sharing stuff with clients is easy and actually looks professional, plus there are a ton of integrations for tools you’re probably already using.

Has delightfully exceeded my expectations!
I am another OG Nimbus purchaser from the very first deal on Appsumo. I am glad to see this deal flourish as it has. They have consistently rolled out new features to stay ahead of the curve with all the innovations in the marketplace.
I had the CEO reach out and ask if I could do a customer feedback session maybe 3 or 4 years ago. They listen to their customers and take action and have a great product.
The note features are fantastic. Right on the heels of Notion in some places and superior in others. All the automation and AI capabilities have made this one of the best deals I have purchased and I have bought a LOT.
If you don't currently organize your digital world well, you will miss out on being your best self and this app with the templates, different block types, collaboration tools, portals and more give us a really polished and organized workspace that garners a lot of trust from anyone who sees our operations.
Highly recommend!
