Google Collabio
Plan a holiday together without the endless group chat.
- Status
- Shipped

Group holidays get planned in the group chat. Dates, budgets, options and opinions, all buried somewhere up the thread.
Collabio puts the trip in one place. Add dates and a budget, propose places, vote, and see the shared plan with open decisions clearly marked.
Group planning is really a coordination service. A vote doesn’t resolve conflicting needs on its own, so the plan has to show the difference between a popular option and a confirmed decision.

Problem
Group trips get planned in group chats. Dates, budgets, options and opinions end up buried somewhere up the thread.
Research
Planned: ask a small group to plan a low-stakes outing with it, and watch where they fall back to chat.
Prototype
A shared trip board: add dates and a budget, propose options, vote, and see a summary of what's decided. [Verify: what's built today]
In people’s hands
Next: test on a phone, with edit conflicts, late joiners, and someone who suddenly can't come.
What happened
The risk: voting can create a false sense of agreement while budget or dates are still unresolved. A popular option isn't a confirmed decision.
What’s next
Make the difference between popular and decided obvious, then handle changes: late joiners, new dates and options that break the budget.
How I’m approaching it
The Double Diamond, as planned. Plans loop back once real people get involved, so this one does too.
