Open the office§ 01 The office
Chat, compare and research with ten open models in one workspace. Pick one, or let Auto choose the right mind for the task.
Keep a project's notes and threads in a room locked with your passphrase. It is encrypted in your browser before it is saved.
Give a clerk a job, a rulebook and a daily allowance. It reads public chain data, drafts, and asks first when a task is above its cap.
Every answer is written down: model, size, time. Close the month into a statement, seal it with your wallet, and let anyone verify it.

Delegate work, keep control
Set a daily allowance for every clerk. Anything above it comes back to you first, and one switch stops a clerk completely.

The idea behind Quillhouse
§ 04 How it works
Go to the app and start asking. No account, no email, no deposit. The free allowance is ready the moment the page loads.
Connecting only reads your address, so clerks can summarise your wallet on Robinhood Chain. Nothing is signed when you connect.
Pick a clerk, give it a brief and an allowance. It works inside its rulebook and asks first above the cap.
Close the ledger into a statement and sign it with your wallet. Share the file; anyone can verify it on the Verify tab.
A seat at the desk
Every feature, free for everyone
§ 05 Pricing
All ten models, compare mode, clerks, rooms and the ledger. Nothing to unlock, nothing to deposit.
Each visitor gets a fair share of answers per day. It resets at 00:00 UTC.
You sign one thing, and only when you choose: the seal on a ledger statement.
The allowance is shared fairly between everyone using Quillhouse. If it runs out on a busy day, it comes back tomorrow.
Bring several models, your notes and your room into one considered workspace.
Give routine work to a clerk, with clear instructions and a bounded allowance.
Principals seal the month, members write, guests see one room through an encrypted invite.
Turn answers and runs into a signed statement your whole team can check.
§ 06 Security
Room contents are encrypted with AES-GCM using a key made from your passphrase, inside your browser. What is stored is ciphertext.
No email, no account, no password. A wallet is optional and only shares an address. Your settings live in this browser.
Before a message leaves your browser, guards look for seed phrases, private keys and API keys. Keys are blocked outright.
Rooms no one
else can read.

The ledger
§ 07 Principles
Every feature is open to every visitor. The daily allowance is the only limit.
Rooms, ledger entries and settings stay in your browser unless you export them.
Models can be wrong and have no internet access. Clerks cite the data they were given.
Statements carry a fingerprint and your signature, so anyone can check them.
Ten open models, private rooms and clerks with budgets. Free, in your browser, on terms you set.
