10 Best Free Brainstorming Apps & Tools

What is the best free brainstorming app?
The best free brainstorming app is Mindmeister. A mind mapping-based collaborative brainstorming tool for teams and individuals, the free app allows you to collaborate with up to three mind maps. Its visualizations make for appealing presentations.

You can brainstorm using the usual collaboration tools like VoIP, chat and project management software. Sure, they let you communicate anywhere and anytime, but these are not designed primarily to follow and correlate ideas. For that, there are brainstorming apps and mind mapping software designed to juice out the best ideas for execution.

If you’re new to this software type–or running brainstorming sessions–you’re better off trying a free tool to walk you through the exercise. We have prepared a list of the best free brainstorming tools that we believe will help you consolidate ideas and flesh out a clear output. Most of these are SaaS small business apps, so manage your expectations if you have enterprise-level requirements.

We will be highlighting the features that make each of these unique, so you can pick the best one for you.  Also, you’ll be able to distinguish the free apps from each other. Some of them are designed for solo use, while others are for collaboration. Some put emphasis on mind mapping, while others on mobility.

Brainstorming can be done both in groups and as an individual. It is a creative problem-solving technique that is very forgiving. Participants throw out ideas that can be a little off the wall hoping to find a very ingenious solution. These can be just reigned in later. But whether you do it with others or yourself, it is preferable to have a board or even toys to play with–tools that will help you think in more abstract ways. The brainstorming area should also be accommodating and the atmosphere light. This is something that a good yet free brainstorming app help recreate. 

Many of us who brainstorm with others use a board to jot down ideas. We pin pictures, charts, and notes. We even draw shapes, make graphs, diagrams, and connect them with arrows. This instinct to scribble, post, and connect concepts is catered to by digital brainstorming aids with collaborative workspaces. They range from digital whiteboards to mind maps. These are also pretty useful even when you brainstorm alone.

It is good to note that some researchers and professionals find solo brainstorming is better. Many believe that group brainstorming is just a waste of time. But then again,  this depends upon the situation. If you ask us, it really depends upon who you are with and what the brainstorming session is for. There is no categorical answer. 

Group brainstorming tools are, in essence, a subtype of collaboration software. They usually come with admin controls, access roles, and a shared dashboard. Just like individual online brainstorming tools, you can access them from your browser or through an app using multiple devices. In this way, you can collaborate with different people wherever and whenever you need them. Individual brainstorming platforms will have similar useful tools that group brainstorming ones except for a collaboration function. You can do your brainstorming alone and just share it with others later. 

10 Best Free Brainstorming Software

1. Mindmeister

Mindmeister dashboard example

Mindmeister is a mind map-based collaborative brainstorming tool. The free version allows you to collaborate with an unlimited amount of people but you only get 3 mind maps. The collaboration feature is included but if you want more mind maps and features, you have to upgrade to a paid plan. The free version allows you to store designs and files such as PDFs. Your maps on Mindmeister get updated in real-time across all devices. It is also accessible to other users allowing for a real collaborative brainstorming session. 

The free version seems to be okay for a limited time as you can only have 3 mind maps. But if you don’t have many projects, you can just reuse the maps you already have.

Should you want to upgrade, the best plan for teams (and individual use) is said to be the Pro plan that costs $8.25 per user a month. It includes custom themes for maps and export options. This allows for multiple team members and seems to be perfect for small to medium teams.

Key Features of Mindmeister

  1. Real-time collaboration
  2. Mind map-based UI
  3. Three free mind maps

2. Coggle

Coggle dashboard example

Coggle is another brainstorming tool for mind map enthusiasts. The free version allows for collaboration and is perfect for occasional brainstorming. It also includes unlimited image uploads, unlimited public diagrams, and full change history. The user interface and graphics are neatly designed. It even includes multiple starting points so you and your team can map several related topics in a single space. Not only that you can add images and floating text, but you can also add branches and loops to model advanced relations and processes. 

Its free version may be enough for occasional brainstormers who want real-time collaboration. There is no harm in trying. 

Once you’re ready to scale, the Awesome plan (personal and professional version) starts at $5 per month. It allows for a larger degree of customization like more control on line paths. It also includes more item shapes. 

Key Features of Coggle

  1. Mindmap tool
  2. Unlimited public diagrams
  3. Real-time collaboration

3. Lucidchart

Lucidchart dashboard example

Online brainstorming is all about visual communications. One way to get ideas across is through charts and diagrams. LucidChart is an excellent way to build these visuals. What’s also cool about it is that you build charts with data. Yes, you can import and even connect live data for your diagrams. But, its free version is only available for an individual. This means, the free tool, is essentially an individual brainstorming platform. Collaborative features are only available for paid plans. Although this is the case, you get access to a free shape library and access to all templates. 

The available templates are useful in a wide array of business processes from IT to sales. If you are in project management, you can create a Gantt chart. If you are in product management, you can build website mockups. LucidChart integrates well with Jive, Google Drive, and Atlassian Confluence.

The Pro plan for single users costs $9.95 per month paid quarterly.  

Key Features for Lucid Chart

  1. Free templates
  2. Build charts with data
  3. Easy to use
  4. Build complex diagrams

4. Mind42

Mind42 dashboard example

Mind42 is another collaborative visual thinking platform. The name is not pronounced as “mind forty-two” instead it refers to the collaborative function as intended to be pronounced as “mind for two”. The platform is totally free and fully runs on your browser. Maybe one downside is that it is ad-supported. It is not like other free platforms that prefer donations to keep them afloat. 

The platform allows you to create private mind maps by default. You can create nodes and connect them with arrows. Each object can be labeled and you can even add pictures. Also, you can add shapes and links as well. The user interface is not the prettiest one out there though. There is much left to be desired in this department. But, if you are looking for something functional and browser-based, there is no harm in trying it out. 

You can collaborate with people by allowing them to edit your maps. You also have the option to share your maps publicly for the world to view and even export it in several file formats. 

Key Features of Mind42

  1. Straightforward user interface
  2. Export to files
  3. Collaborate via invites

5. Popplet

Popplet dashboard example

For personal brainstorming use, the free version of Popplet might be enough. It is a straightforward application that, as many other brainstorming tools online are, is mind mapping-based. It is targeted at students, educators, and businesses. The user interface is very straightforward with drag-and-drop controls. It also has a corresponding app which is only exclusive to Apple users. If you are on Android, you can still access it via your browser but there is no app for it.  

Essentially, Popplet is a mind mapping tool perfect for people who prefer maps than any other method. But, if you want a more flexible application, this may not be for you. However, collaboration is pretty easy to do with the tool. If you are an educator, for example, you can let the class participate in digital activities. Students can create presentations using the materials that were brainstormed in Popplet. There are many uses for it. Your creativity is the limit.

Best Free Brainstorming App for Different Needs

So, what is the best free brainstorming platform for you? Certainly, it depends on what you need it for. For example, if you are a creative professional, Milanote might just fit your purpose. It offers a whiteboard-based workspace where you can build mock-ups and improve on your designs. If you are an educator, Popplet can be a good tool to facilitate brainstorming and reporting for your students. Do you work in a team? Stormboard or Miro may capture how a real-time collaborative brainstorming session for you. If you are a mindmap enthusiast, free tools such as Mind42 and Wisemapping may just do the trick. 

But, if you have a general need for a brainstorming app and want one that is robust yet flexible, we recommend Mindmeister. It allows for solo and collaborative brainstorming and scales to premium features. Furthermore, its visualizations lend to your brainstorming stunning presentations, plus it has a built-in project management feature (premium) should your concept exercise turns to a full-blown, high-value initiative.

Meantime, it is good to note that if you really want to stick with free plans and apps, you can also use a platform stack. What we mean by this is that you improve communications in your real-time workspace collaboration by having a video conferencing software up as well. 

There are many studies and differing views out there about brainstorming. Interestingly, one that should catch your attention though is that some have found online brainstorming to be better than an in-person session. The reasons for this can include shyness, scarcity of tools, and access to proper information. Some people are understandably shy. Therefore, they contribute in the best way they can when they can be anonymous. Some people contribute better when they have visual tools and have access to information (the internet). Virtual brainstorming is not the best way to move forward with everything. Also, it is not for everyone. But, it might help you from time to time depending on your tasks. So, try one or more applications presented above if you would like to see whether virtual brainstorming is effective for you.

Brilliantly helpful ! Thank you !
About 50 years ago, ( when retail computers ( Amstrad etc) had TINY memories ) someone came up with a terrific programme which they had actually called ‘Brainstorm’.
It allowed you to enter individual lines of text which then instantaneously cross-referenced with other lines of text which had matching elements in lines that you had earlier entered.
Additionally, you could arrange these entries in hierarchical order ad infinitum, grandparent-parent-child-grand child.
I’ve been looking for it ever since !
