01 / THE RECORD
Five people argue your decision until they land somewhere.
5 PERSONAS · 30 TURNS · ONE VERDICT
Should we ship the migration on Friday?
DenizWe are not shipping an untested rollback on a Friday night, full stop.
RanaFriday is in writing to our largest account, so we ship or we explain why we lied to them.
VERDICT
The group reached a sound, unified decision: run the rollback against a production snapshot tonight with Yusuf present, share results with everyone, and ship Friday only on a clean pass — otherwise call the customer Thursday morning with a revised date. The practical recommendation is to execute exactly this plan, assign a named decision-maker for the Thursday go/no-go call, and document the condition explicitly so no one can reinterpret 'Friday holds' as unconditional on Friday night.

Get it on Google Play
EchoSwarm is live on Android. iOS comes after it, and there is no date yet — we would rather say so than invent one.
App Store — soon
Leave an address below and you get one message: the day the iOS app is live. Nothing else.
03 / HOW IT WORKS
You ask. It casts the room. They argue. You get a judgment.
Write the decision you are stuck on. EchoSwarm casts the room from it — a handful of characters, each with a persona and something they want — and you can edit or replace any of them. Then they take turns. They answer each other by name, change position, and stop when the run ends.
Nothing here is a chatbot answering you. The point is the disagreement between the people you cast, and what survives it.
04 / THE ROOMS
Every recorded room keeps its own address
Each room recorded on this site is a page. Send the link to whoever needed convincing — they get the argument and the reasoning, not a screenshot of a conclusion. In the app, your own runs share as a card with the verdict, and on the paid plan you can export a whole run.
Browse the rooms — 6 recorded.
05 / BOUNDED
Runs end on purpose
A run finishes. That is a product decision, not a limit we regret: a conversation you can read to the end is worth more than one that scrolls forever, and the graph stays legible when the cast is bounded.
Concretely — the free tier runs 4 agents for 20 turns, three times a day and thirty times a month. The paid plan, $9.99 a month in the US, goes to 50 agents and 50 turns a run and 500 runs a month, and if a month needs more than that you buy more runs outright rather than waiting for the calendar. The rooms above were recorded at 30 turns, which is why their counters read 30 and not 20.
06 / QUESTIONS
What people ask before they install it
- What is EchoSwarm?
- EchoSwarm is an Android app that turns a decision you are stuck on into an argument between AI characters. You write the question, the app casts characters who each want something different, they argue it turn by turn on a live graph, and you get a written verdict: who held which position, what turned the room, and what it recommends.
- How much does EchoSwarm cost?
- EchoSwarm is free to start: the free tier gives you 4 characters, 20 turns, 3 runs a day and 30 a month, and web research on 1 question a day and 10 a month. The paid plan is $9.99 a month in the US (Google Play shows your local price) and gives up to 50 characters, 50 turns a run instead of 20, 500 runs a month, web research on 100 questions a month and export of any run. Extra runs can be bought once, 1,000 for $19.99 or 2,000 for $24.99, and they do not expire.
- Is EchoSwarm on iPhone?
- Not yet. EchoSwarm is on Android, through Google Play. There is no iOS date; you can leave an email address on echoswarm.app and get one message on the day the iPhone app is live.
- How is EchoSwarm different from asking a chatbot?
- A chatbot gives you one answer in one voice. EchoSwarm casts several characters with conflicting goals and makes them argue, so the useful part is the disagreement and what survives it. The verdict names who held which position and which moments changed the room.
- Is what the characters say advice?
- No. A run is a simulation. The characters are generated by AI, they know nothing about your situation beyond what you typed, and nothing they say is the opinion of a real person or a professional. EchoSwarm is not a lawyer, a doctor or a financial adviser; use it to find the argument you had not thought of, then check it.
- What should I write to get a good run?
- Name the place, name the people and say what each of them wants, say what has already happened, and say what it costs you to get this wrong. A vague question still runs all 20 turns, but it circles, and the verdict comes back as thin as the question was. The guide at echoswarm.app has worked examples.
- Which languages does EchoSwarm support?
- The app is available in ten languages: English, Turkish, German, French, Spanish, Russian, Arabic, Chinese, Japanese and Korean.
- What happens to what I type?
- Your question and characters are sent to third-party AI services to generate the dialogue, and only to run your swarm; the privacy policy names each service. There are no ads and no analytics or tracking SDKs. Your account is an anonymous identifier on your device, and you can delete it and every run from the app's settings.
- Can I share a run?
- Yes. In the app you can share a card with the verdict and a picture of who argued with whom, and on the paid plan you can export the whole run. The rooms recorded on echoswarm.app each have their own page you can link to.
07 / ON PHONES
This page is the recording. The app is the room.
Everything above is a finished run, read after the fact. In the app you cast the room yourself and watch it happen — the graph moves as each agent speaks, and you can pause, step a single turn, or rewind to any point in the argument.
That is the part a page cannot show you. Here is what it looks like while it happens.
