Online Brainstorming Tool

Spatial rooms where your team walks, talks, and thinks out loud together

By Flat Team·

Your team needs to brainstorm. So someone opens a shared doc, types "Ideas:" at the top, and waits. Three people add sticky notes to a digital whiteboard. Everyone else stays quiet. The loudest voice wins. The best ideas never surface because half the team checked out after two minutes of staring at a blank canvas.

Now picture this on Flat.social. Your team walks into a spatial room with three brainstorm zones: a whiteboard area, a sticky note wall, and a campfire for open discussion. Two designers huddle near the whiteboard sketching concepts. The product lead drops sticky notes on the wall while chatting with an engineer through spatial audio. Someone overhears an idea as they walk past and jumps in with a build. That's what an online brainstorming tool looks like when it's built for conversation, not just sticky notes.

Flat.social gives your team a room they can move through, talk in, and fill with ideas. Multiple groups brainstorm at once. The best ideas come from the collisions between them.

Ideas Flow Through Conversation

Walk up to a teammate and start riffing on ideas. Spatial audio makes brainstorming feel like gathering around a table, not staring at a screen.

What is an online brainstorming tool?

An online brainstorming tool is a digital platform where teams generate, share, and develop ideas together in real time. The most effective tools go beyond shared whiteboards by supporting natural conversation, parallel group work, and spontaneous idea exchange across distributed teams.

Why Teams Pick Flat.social as Their Online Brainstorming Tool

Walk-Up Conversations
Spatial audio lets you walk your avatar next to someone and start talking. No hand-raising, no "you're on mute." Brainstorming happens naturally through proximity, just like clustering around a whiteboard in person.
Parallel Brainstorm Zones
Audio isolation zones let you run three brainstorm groups in the same room without interference. The design team sketches in one corner while engineering discusses architecture in another. Walk between zones to cross-pollinate ideas.
Whiteboards & Sticky Notes
Place whiteboards and sticky notes anywhere in the room. Sketch, write, and organize ideas visually while talking through them with spatial audio.
No Downloads Needed
Share a link. Your team clicks and joins in the browser. No app installs, no plugins, no accounts required for guests. Brainstorming starts in seconds.
React and Vote
Drop hearts on your favorite ideas. Send fireworks when someone nails it. Five reaction types give your team a fast, visual way to signal which ideas resonate.

Overhear, Jump In, Build On

Proximity-based audio means you catch fragments of nearby conversations as you move through the room. That's how the best brainstorm moments happen: someone overhears an idea and adds the missing piece.

How to Run an Online Brainstorming Session on Flat.social

  1. 1
    Create your brainstorm room

    Sign up at flat.social and create an Open Spatial room. Choose a map template with open areas or start from a blank canvas. This is your brainstorm space.

  2. 2
    Set up brainstorm zones

    Use build mode to create distinct areas. Place a whiteboard in one zone for sketching. Drop sticky notes in another for quick idea capture. Set up a campfire area for open discussion. Add billboards with brainstorm prompts or challenge statements to guide the session.

  3. 3
    Invite your team

    Copy the room link and share it on Slack, Teams, or email. Enable guest access so external collaborators can join without creating an account. Everyone opens the link in their browser and walks in.

  4. 4
    Warm up with speed ideation

    Launch speed networking mode for quick 1-on-1 rounds. Give each pair 90 seconds to share one idea related to the topic. After 4-5 rounds, everyone has heard a dozen starting points. Energy is up. The real brainstorm begins.

  5. 5
    Let groups form naturally

    Don't force everyone into one conversation. Let people spread across the brainstorm zones. Some will sketch on whiteboards. Others will cluster around sticky notes. A few will riff verbally near the campfire. Walk between groups to connect the dots.

  6. 6
    Converge and vote

    Gather everyone near the sticky note wall or whiteboard. Walk through the top ideas together. Use reactions to vote: hearts for strong ideas, fireworks for breakthroughs. The spatial layout makes it easy to see where energy clusters.

Tips for Facilitating Online Brainstorming Sessions

Running a brainstorm on Flat.social is different from running one on a video call. The spatial format changes how ideas flow. Here's how to make the most of it.

1. Build the room before people arrive. Spend 10 minutes in build mode setting up zones with whiteboards, sticky notes, and billboards. A well-designed space signals "this is a creative session" the moment people walk in. It also saves time explaining where to go.

2. Start with energy, not instructions. Open with a 2-minute speed ideation round or a quick virtual icebreaker game. Get people moving and talking before the real brainstorm starts. Flat.social's spatial format rewards movement, so get avatars out of the spawn point fast.

3. Don't force one conversation. The biggest advantage of a spatial brainstorm is parallel thinking. Let 2-3 groups work independently, then bring them together to share. You'll get more ideas in 20 minutes than an hour on a video call. This same approach works great for virtual hackathons too.

4. Use billboards as prompts. Place billboards around the room with "How Might We" questions or challenge statements. They guide the brainstorm without you having to repeat the brief. Teams can reference them as they move between zones.

5. End with a gallery walk. After the brainstorm, have everyone walk the room and react to their favorite ideas. Hearts and fireworks make voting visual and fun. It also ensures quiet team members get their ideas seen. This is a great free online brainstorming tool technique that costs nothing to try.

Tips for Brainstorm Participants

Joining an online brainstorming session on Flat.social? Here's how to contribute your best ideas.

Move around. Use WASD to explore the room. Walk past different groups and listen in. The best ideas often come from connecting two conversations you overheard in different zones. Think of it as an online brainstorming board you can physically walk through.

Write first, talk second. Drop a sticky note with your idea before discussing it. This prevents louder voices from dominating and gives introverts equal space. Then walk to where people are gathering and talk through what you wrote.

Build on others' ideas. When you spot a sticky note or whiteboard sketch that sparks something, walk over and add to it. Place your sticky note next to theirs. Sketch on the same whiteboard. The spatial layout makes it obvious when ideas are connecting. It's the same dynamic that makes virtual coworking spaces so productive.

React generously. See an idea you like? Send a heart reaction. Someone proposes something bold? Fireworks. Reactions give the facilitator a quick read on which ideas have energy behind them.

Multiple Groups, One Room

Audio isolation zones let separate brainstorm groups work in the same space without hearing each other. Walk between zones to carry ideas across teams.
