Sound familiar?
Every group has a decision-making bottleneck.
47-message group threads that end with "idk, you pick"
Plans that fizzle because nobody actually committed to a call
The loudest voice wins instead of the best idea
Better ideas in. Better decisions out. One link.
See it in action
Three steps. Under a minute. Better ideas in, better decisions out.
Find the option everyone can stand behind
Lumen scores every option across rating, consensus, and participation — finding the pick that satisfies the most people, even when preferences pull in different directions.
Your whole group, one link
Share a link and they join instantly. No download required. Manage roles, permissions, and who can add options.
Add options — or let AI suggest some
Add ideas yourself, or get AI-generated options tailored to your topic. Then everyone weighs in with star ratings, token allocation, or single choice. Nothing gets overlooked.
From dinner plans to product plans
Wherever a group needs to make a call — Lumen helps you brainstorm stronger options and land on the best one.
Where are we eating tonight?
Friends & nights out
Where are we traveling?
Trip & event planning
What’s our next book?
Clubs, crews & communities
What should we build next?
Product teams
Which vendor do we pick?
Operations & procurement
And everything else
Couples, roommates, families
Three ways to vote
Different decisions call for different methods. Pick the one that fits your group.
Star Rating
Rate each option 1–5 stars. Best when every option has trade-offs and you want everyone's nuanced take — vacation spots, restaurant picks, sprint priorities.
Token Voting
Allocate limited points across options. Forces real prioritization when you can't pick everything — budget calls, group itineraries, gift-list trimming.
Single Choice
One vote, one pick. Fast and decisive when you just need a commitment — what movie tonight, which vendor, which paint color.
Vote together or on your own time
Not every group is in the same room — or timezone. Lumen works either way.
Live Voting
Everyone votes at the same time. Results update in real time. Perfect when the group's together — dinner table, planning meeting, watch party.
Async Voting
People vote on their own time. Results are revealed once everyone has weighed in. Built for distributed teams, cross-timezone friend groups, and anyone too busy for another call.
Generate options. Surface signal.
Stuck on what to even put up for a vote? Lumen's AI suggests options tailored to your topic. Once votes come in, it surfaces the themes, splits, and consensus your group might have missed — so you find the call everyone can live with, not the loudest one.
