Brainstorming online: a brainstorm website, tool and web app, no workshop required

Team brainstorming online usually means a calendar invite, a video call, a shared whiteboard, and forty minutes of warming up before the first honest idea. The workshop format survives because it used to be the only way to get parallel thinking from a group. It is not anymore.

Brainstormer takes a blunter route: it runs the divergence for you, so there is no session to parallelize. One person types the challenge and six personas answer it in under a minute, and what comes back is a shortlist and a pick you can bring to the one short call that still needs to happen. To be clear about what that is not: there is no shared wall, no in-app voting and no async collaboration here, so teammates each run their own and compare. Our guide on how to run a brainstorming session covers the group formats honestly.

The best way to brainstorm online with a remote or distributed team is asynchronously on a shared wall, not on a live video call. Async removes the two things that quietly ruin virtual sessions: the scheduling tax of finding one slot across time zones, and the anchoring that sets in when the first person to speak frames the direction for everyone else. Each teammate contributes in writing on their own schedule, and the group votes before anyone argues.

Doing that properly needs a shared canvas, and that is genuinely not what Brainstormer is: there is no shared wall, no async voting and no facilitator mode here. Where it fits a remote team is one step earlier, as the thing that fills the blank page before the async round starts, so people are reacting to twenty real directions instead of staring at an empty board. Our guide to running an innovation workshop builds on the same async-first approach.

Working alone, the tool is the room: it generates around twenty directions so you never face a blank page, it argues with itself through six personas instead of nodding along, and it ends on a pick. The full arc, from challenge to shortlist and winner, fits inside a coffee.

Nothing to install, nothing to facilitate: it runs in any modern browser, and the brainstorming app experience works from a phone when the idea hits on the walk.

Four things, and most brainstorming websites do only the first. It should hold the ideas, obviously. It should produce them, so nobody starts at a blank board. It should keep them genuinely different, because the natural drift of any group or any model is toward variations on the first suggestion. And it should end the session with a ranked shortlist and a written reason, because that sentence is the only part that survives into next week.

Judged that way the category thins out fast. Online whiteboards are excellent at holding and arranging, and they generate nothing: the board is as full as the room made it. Note and doc apps hold even more and organize less. Chat assistants generate well and hold nothing, since the session lives in a thread you have to keep pasting forward. The honest breakdown of who does what is on our ideation tools page, and the vendor-by-vendor version with prices is on best brainstorming software.

Collaborative brainstorming online adds one more requirement: the wall has to stay useful when people arrive at different times. That means new arrivals see what exists, the tool pushes them away from repeating it, and votes accumulate rather than being cast in a single meeting. That is the async setup described above, and it is what makes a shared wall better than a call for most weeks.

Automated brainstorming is running the generation step with software instead of a room: you supply the challenge, the tool produces the field of ideas, and the people spend their time judging rather than producing. The part that gets automated is idea supply. The part that does not, and should not, is deciding which idea is worth anything.

The distinction matters because "automated" is doing a lot of work in that phrase. Nobody wants an automated decision, and any tool that hands you a single confident answer to an open problem has automated exactly the wrong half of the job. What is genuinely worth automating is the grind: getting past the six obvious directions everybody already had, keeping the options structurally different rather than six phrasings of one idea, and reading the wall one angle at a time afterward. Those three tasks are mechanical, they are where sessions actually stall, and none of them requires human judgment to perform, only to check.

In practice an automated pass looks like this. You write the challenge as one specific sentence. The studio returns around twenty directions, each tagged with the angle it came from, in about thirty seconds. The same wall can be read persona by persona, so you can see which angle the field is dense in and which one came back thin. Then a human reads the themes and decides, which is the step that was always the point. There is research behind the split: a Wharton study comparing 200 MBA-student ideas against 200 from GPT-4 found the model produced its 200 in around fifteen minutes against roughly five ideas per person per fifteen minutes, and its ideas rated slightly higher on average purchase probability while rating as less novel and more similar to each other. Volume and speed from the machine, novelty and judgment from you. We walk through the numbers in is AI good at brainstorming, and the mechanics of the generation step are on brainstorm with AI.

It depends which of the four jobs you need done, and almost every site on the shortlist does one of them well and the others badly. Sort the candidates by what you are short of: a place to put ideas, a source of ideas, a way to keep them different, or a way to end with a decision.

If the room reliably fills a wall and the problem is that nothing happens afterward, you need convergence, not another canvas: clustering, scoring and a written rationale. If sessions start with silence and end with four variations on whatever the loudest person said first, you need generation and forced variety, which is what this site is built for. If the constraint is that your team is in four time zones, the requirement is asynchronous accumulation, so a site where votes and ideas pile up between sessions beats any live-only tool regardless of how good its canvas is. Ranked comparisons with current US prices are on best brainstorming software, the category split by product type is on ideation tools, and if you are choosing between whiteboards specifically, the verified pricing pages for Miro and Mural cover what each tier actually unlocks.

Yes. Everything on this page runs in a browser tab: no download, no desktop client, no plugin, and nothing for IT to approve. The studio above this text is the actual product rather than a video, so you can type a challenge into it now and watch a full wall of ideas appear in about thirty seconds. An account is what you need to keep a session and read it back later, not to run one.

That matters more than it sounds, because "brainstorm online" is usually typed by someone who has ten minutes and a problem, not by someone starting a procurement process. Most of the category makes you sign up before you see anything work, which is a reasonable business decision and a bad answer to that particular moment. It also works from a phone browser, which is where a surprising share of solo brainstorms actually start, and the same session picks up on a laptop later. The mobile experience is covered on our brainstorming app page.

A lot of people are searching for a brainstorm website in 2026 because the desktop tool they used is going away. Microsoft is deprecating the standalone Microsoft Whiteboard apps on November 30, 2026 and permanently deleting unmigrated legacy whiteboards on October 16, 2026, with whiteboarding continuing inside Microsoft Teams rather than as its own app.

If you only ever used a whiteboard during meetings, the Teams version covers you and costs nothing extra. The people genuinely displaced are the ones who opened a standalone app to think alone, away from a meeting client, which is exactly the solo browser session this page describes. We laid out the full deadline table and how the paid canvases compare on Microsoft Whiteboard alternatives, and the how-to for running the session inside Teams itself is in brainstorming in Microsoft Teams. Worth checking one thing before you pick a replacement: if the boards you are migrating are mostly half-finished brainstorms, the constraint was never the surface.

A free account runs 3 brainstorms a month. Solo at $16 per month removes that cap, and Pro at $39 adds priority support and your full session history. Team at $99 is for accounts that want invoicing and a faster reply from us rather than any extra feature, and we would rather say that plainly than dress it up. Either way the output is the same: around twenty ideas, a shortlist, and one pick with the reasons attached.
