As a freelancer managing multiple clients, finding the right tool to streamline my workflow has always been a challenge—until I discovered FuseBase.

This platform is a game changer! The ability to create a fully customizable client portal has saved me hours of juggling between emails and project management tools. The project and task management features are incredibly intuitive, allowing me to seamlessly collaborate with my clients and team members.

What truly stands out is the user-friendly dashboard, which makes setting up and managing everything a breeze, even for someone who isn't overly tech-savvy.

Plus, the workflows and automation features are a lifesaver—they've helped me stay organized without the usual stress.

FuseBase is easily the best investment I’ve made for my freelancing business. I’d highly recommend it to any freelancer or agency looking for an all-in-one client management solution!

FuseBase has completely revolutionized our workflow. It's the ultimate all-in-one solution that ended our struggle with scattered projects and client communication. We now automate teamwork in secure, AI-powered workspaces with ease.

The dedicated client portals are a game-changer, making collaboration seamless and professional. Best of all, the 24/7 AI agents handle the repetitive busywork, freeing our team to focus on strategic priorities. Our productivity has soared, and client satisfaction has never been higher. An essential investment for any business looking to optimize its operations. Truly a 5-star tool!

As a consultant and agency, we’ve been using Fusebase with all our B2B clients, and it’s become their go-to tool for connecting with clients, vendors, and their own teams. We’ve created these custom portals for them, and it’s totally transformed how they handle projects and relationships. It’s like saying goodbye to all those messy email threads and hundreds of Google sheets and docs, and hello to a single, easy-to-use portal!

What we love most is how it gives our clients the power. We can set up a super polished, white-label portal in just a few hours that feels like it belongs to their brand. The drag-and-drop blocks and reusable templates are a huge time-saver, so we can whip up and clone things like onboarding packs in a flash. And those targeted AI agents? A game-changer! Our clients are thrilled that their stakeholders can get instant, accurate answers from specific documents without having to ask for help.

When it comes to collaboration across stakeholders, the portal is truly unmatched. We’ve seen our clients bring together their customers, external vendors, and internal project managers into one awesome workspace. A vendor can upload a deliverable, the client can review and comment right on it, and the internal team can track progress on a shared dashboard, making sure nothing slips through the cracks. It turns all that scattered, multi-party coordination into a super streamlined, accountable process.

Plus, knowing that the platform supports SOC 2 and HIPAA compliance gives our clients the peace of mind they need when handling sensitive information.

I’ve been using it for several years now to work with data, where my team and I cook and conjure things up in the background (the kitchen) and then serve it to clients on the portal (the dining room). It’s a fantastic app for projects where you want full control over how the client portal will look. I’m excited about the new features: Built-in CRM, Memberspace in Portals, and Custom Boards—DB & Kanban for project management.

Started to use this app with a curious mindset. Then after testing out its capabilities, it is clear that this is very powerful productivity platform. And the "Client Portal" feature just makes perfect sense for its capabilities as sharing info with clients using this tool makes content look more professional. Though it looks like I still have to dive deeper into the Portal feature to make the best of it. Been wanting for an alternative to Notion, but it would be unfair to call this an "alternative" because it just stands on its own.

Pros: I find the way to write notes (pages) is very easy to do, and can have a variety of content thanks to the lot of blocks and embed options that it has. Customizability for the workspace branding and sharing links is awesome on its own, and better than what competitors offer.

Cons: Learning curve. I spent a good amount of time learning to use this app and reading the knowledgebase, and I still feel that there are a lot left for me to grasp. Basic note-taking and note-sharing is the exception, though, as it took me almost no time to get the hang of it (I don't want to say "master").

Overall Impression: Amazingly powerful productivity, note-taking, and note-sharing tool with potential for some creative use-cases like document management, digital logbook, diary, etc. Highly recommended especially for people like me who love a good note-taking app (and productivity tool).

I haven’t left many comments here, even though I already bought a couple of products. However, I highly recommend Fusebase to anyone who needs to organize their work and projects within a team as effectively and flexibly as possible. I bought the first three codes back in 2020 and have kept adding more as Fusebase has continually added new features, including AI. With Fusebase, there’s little other software I need to get my work and projects organized and done! I’m looking forward to testing and using the new features mentioned in your roadmap. Keep up the good work!

I run a small consulting advisory and have been using Nimbus Note (now called FuseBase) since 2020 when I moved my whole knowledge base out of Evernote. 5 years into a Business Plan lifetime deal I feel in a good position to give a frank, practitioner's opinion for Sumolings who care about productivity tools that actually work in the day-to-day pressure.

FuseBase has become a feature-rich product. The ambition of the team to be more than just a notebook (integrating task management, web clipping, collaborative docs and now increasingly AI-powered features) is apparent in the product and marketing. Product updates and the company site talk about expanded integrations and a push into more automated workflows. That ambition is good: as a consultant I want a one-stop shop for capturing meeting notes, clipping research, annotating files and doing quick analyses without switching tools. Where FuseBase does well is in how the product has blended multiple use cases. The UI supports both structured notes and freeform capture, it can store attachments and web clips, and customer support has been responsive when I have needed help.

But the rebrand from Nimbus to FuseBase is still not finished: domain redirects are inconsistent, some pages and links point to nimbusweb.com and important desktop continuity has been forgotten. My Mac desktop client is stuck in limbo: it has not received the polished modern refresh I expected and for years now the behavior and performance is behind the web app. One concrete casualty has been extensions: The Nimbus Clipper was removed from my workflow and not replaced with a clear, direct alternative. For consultants who live in the browser and clip research all the time that is a real workflow regression. Performance is my biggest recurring complaint.

FuseBase is functional but often slow. Search queries and note opens can impose multi-second waits, sometimes I have seen one-to-three second delays that feel trivial in writing but add up to real friction across a day of client work. The public messaging of the platform has not addressed this. Other modern note platforms – historically Evernote – set a baseline expectation for near-instant search and navigation. The feature proliferation of FuseBase is promising, but not if the core experience of capturing and retrieving information is still sluggish.

I am also watching the company's strategic focus with cautious optimism. The recent moves to promote AI features and "agents" are in line with industry trends and will attract new users but risk shifting development and product attention away from core note capture, clip reliability, desktop parity and speed. Personally, I don't need fancy AI assistants embedded everywhere, I need fast, reliable input, editing and search, plus robust clipping and sync behavior. If FuseBase puts more engineering effort into shiny AI demos than into the nuts and bolts of syncing, indexing and client stability, long-time users like me will feel neglected.

For potential buyers on AppSumo: FuseBase is worth a look if you want a single platform that tries to replace a constellation of apps (note taking, web clipping, lightweight tasks and collaborative docs) and you care about responsive support. The lifetime deal I bought made the financial decision easy years ago. If you are deciding now ask specific questions about Mac desktop parity, the status of browser extensions and performance benchmarks for search on data volumes similar to yours. Test the web clipping and search on a free account with real workload before you commit. If your priority is blinding speed, frictionless search and an absolutely solid desktop client, proceed with caution. FuseBase can be slower than competing tools and the rebrand inconsistencies suggest some execution risk. If the team prioritizes polishing the fundamentals (restoring and improving the clipper, accelerating search indexing and shipping a reliable Mac desktop experience) FuseBase could be a best-in-class consolidated workspace. Until then it's a powerful evolving product with moments of brilliance and still many rough edges.

FuseBase used to have an "export all" feature, but it was quietly removed. Even worse, I can't see it on the roadmap. That means once your data lives inside FuseBase, you're effectively locked in with no straightforward way to back it all up or migrate elsewhere.

For any modern productivity tool, data portability isn't a nice-to-have, it's table stakes. Removing this function signals the opposite: vendor lock-in by design. Without an export-all option, every new note, file, or project you create becomes harder to extract over time.

FuseBase has strong collaboration and knowledge-management features, but the lack of data freedom casts a long shadow. Until they bring back a proper bulk export, users should be aware that convenience today could turn into a cage tomorrow.

I use FuseBase every single day as my central hub for note-taking, project planning, and client collaboration. It has replaced multiple tools for me by bringing everything into one streamlined, professional workspace.

What I love most: It helps me centralize my projects and notes in one hub :
• All-in-one: notes, tasks, docs, and client tracking in a single place, no more switching between Notion, Google Docs, and Evernote.
• Customizable, branded client portals that elevate the professional experience and simplify collaboration
• Built-in AI agents that summarize meetings, generate recaps, assign tasks, and follow up, saving me tons of time on emails and admin work
• Productivity boosters: browser extensions, email integrations, transcription and OCR with AI enhancements

If you run consulting, training, or agency work, or simply need a powerful hub to keep projects and client communication organized, FuseBase is a game-changer. It has become my daily operations center and one of the best investments I’ve made.

I’ve been using it to organize information and plan, and it’s been incredibly helpful and user-friendly. I’m excited to explore its full potential as I keep building and developing my projects. It’s a great companion for staying organized and making progress. Looking forward to seeing how it supports me further in the future!

Impressive all-in-one platform for collaboration, project management, and knowledge sharing with a clean interface.
Pros:
Centralized hub for documents, tasks, and communication, especially with clients via portals.
Smooth integrations/webhooks with popular tools
Customizable workflows for teams of any size
Strong focus constant development and updates.
Solid founder, been around a while.
Cons:
The learning curve can be slightly steep at first, but once mastered, it is good.

Overall, it is a powerful tool that enhances team productivity and is absolutely worth stacking..
Thanks team Appsumo and fusebase...

Been using this since the Nimbus Notes days and honestly, it's become my go-to for everything. I have terrible brain fog sometimes and this platform has been a lifesaver for getting all my scattered thoughts out of my head and into something organized. The way you can nest folders and tag everything means I actually find stuff later, which used to be a nightmare for me.

What really impressed me is how flexible it is across different projects. I've built knowledge bases for clients, set up community spaces, and even run entire project workflows - doesn't matter what industry you're in, you can make it work exactly how you need it. The customization options are solid without being overwhelming, and clients always seem impressed when I share portals with them. It's one of those tools that just gets out of your way and lets you work
