Plan outings together,
decide fairly.

Group plans stall because everyone has an opinion and no one has a decision. KARAR turns the debate into a vote, then handles the map, the meetup and the bill.

Everything the group needs, in one place

From “where should we go?” to “who owes what”, without the twelve-message thread.

01

Discover amazing places

Explore trending spots, top-rated venues and hidden gems in your city. Smart search, personalised picks and grounded AI recommendations that actually know the place.

02

Plan outings together

Create an outing, invite the group, and let everyone suggest places. A time-bound, anonymous vote closes on schedule and picks the winner, so nobody has to be the bad guy.

03

Share the memories

Follow each other live on the way there, capture the moments, then scan the receipt to split costs automatically. Everything from the night stays in one shared place.

Four steps from idea to outing

  1. 01

    Create the outing

    Pick a date, invite your gang, and set when voting closes.

  2. 02

    Suggest places

    Everyone adds candidates, or asks KARAR's AI for grounded suggestions.

  3. 03

    Vote it out

    Anonymous, time-bound voting. When the clock runs out, the decision is made.

  4. 04

    Meet & split

    Track each other live, then scan the receipt to settle up fairly.

Small details that end the argument

Fair, time-bound voting

Anonymous ballots and a countdown mean the group decides, not the loudest person in the chat.

Live group tracking

Watch everyone converge on the map in real time, with sharing that expires when the outing ends.

Scan-to-split bills

Photograph the receipt and OCR itemises it, so everyone pays exactly their share.

Grounded AI suggestions

Recommendations drawn from real venue data, not hallucinated names that turn out to be closed.

One shared timeline

Upcoming and past outings, photos and receipts live together, so the memory outlives the group chat.

Friends & privacy

Granular privacy settings, and live locations are deleted automatically once the window closes.
