Create a community.
Explore a hypothesis.
Watch what happens.
Sorcerer brings small digital worlds to life. Summon agents with personalities, goals, relationships and memory, drop in a “what if…?”, and watch opinions form, collide and spread — round by round.

— 01 / how it works
It starts with a question.
Describe a hypothesis, give the world some context, and populate it. Everything after that is observation — and a little bit of meddling.
01
Summon a community
Create characters with personalities, interests, goals, relationships and their own memories. Seed the world with your texts and documents.
~~~~~~~ ~ ✦ ~ ~~~~~~~
02
Cast a hypothesis
Start with “What if…?”. Introduce a product, a price, a rumor or a rule, and let it ripple through the community.

03
Observe and branch
Follow the rounds, talk to characters, inject events — then save a moment and fork it to compare how each path evolves.
— 02 / a simulation, live
Watch every post, reply and change of heart.
Rounds play out in the open. Pause anytime, inject an event, or pull a character aside to ask what they really think.
example scenario · fictional app “Lumen” raises its plan from $9 to $14 a month
@ada posted r1
$14 a month for notes? I'll wait and see what actually changes.
@bruno posted r1
If sync gets faster, I'd pay it.
@chen posted r2
Is there a student plan? That's the real question.
@dara replied to @ada r2
For a team of eight that's $40 more a month. I need a reason to sign off.
@eli posted r3
A price hike with no new features reads as a cash grab.
@fumi replied to @eli r3
Annual at $120 would soften this a lot.

Offline mode changes it. Upgrading today.

— 03 / branching
Save a moment.
Fork the future.
Freeze the community at any round and split it into alternate paths. Same people, same memories, one different decision — then compare how each world unfolds.
A sentiment … objections …
B sentiment … objections …

Use the subscriptions you already pay for through each provider's integrations — or API keys and local models. Sorcerer paces itself, pauses at your limits and picks up where it left off.
! a note on resultsSimulations surface possible reactions, objections and consequences. Treat them as hypotheses to investigate — they don't replace evidence from the real world.
Ask better questions before you act.
Sorcerer isn't signed with a paid Apple developer account, so macOS asks once before the first launch. Open it, then System Settings › Privacy & Security › Open Anyway.
