one prompt,many minds
strophae is a desktop app for macOS and Windows. You write the prompt once. Every agent in your council answers it at the same time, each with its own model, system prompt and colour, streaming live in its own column.

features
compose your council
Four browser tabs and the same question pasted four times is not a workflow. Give every seat at the table a voice, then ask once.
personas
agents with a point of view
Name, colour, model and system prompt per agent. Save the good ones as personas and seat them again next session.
models
any model, one key
OpenRouter carries GPT, Claude, Gemini, Llama, DeepSeek, Mistral and hundreds more. The model list is yours to edit in Settings.
attachments
bring your documents
PDF, Word, Markdown, CSV and images attach to the shared context, to a single agent's brief, or to one message.
rich replies
beyond plain text
Mermaid fences render as real diagrams inside the column. Image models paint into the conversation, audio models speak.
languages
in your language
The interface speaks English and Italian and follows your OS. Your words and the models' replies are never translated behind your back.
screenshots
the council at work
Two real sessions, captured straight out of the app.
three painters, one storm
Give each agent an image model and its own brief. The same prompt comes back as three different canvases, streamed into their columns and kept with the session. One button saves any of them to disk.
one decision, six angles
The bundled persona library seats de Bono's Six Thinking Hats around your question: facts, emotion, judgment, benefit. Every answer lands as formatted markdown, tables and all, that you can read side by side.
In Greek drama the chorus turned as one and answered the scene in strophes. Many voices, one line to answer. strophae is that chorus for your questions.
privacy
no accounts. no server. no telemetry.
local by design
Sessions, agents and attachments live in a single JSON document in your user folder. Delete the folder and strophae never knew you.
your key, in the keychain
The OpenRouter API key is encrypted at rest with the OS keychain (safeStorage) and is only ever sent to OpenRouter.
one outbound host
The renderer's Content-Security-Policy allows exactly one network destination: openrouter.ai. Nothing else leaves the app.
run it
running in a minute
strophae is built with Electron, Bun and React. All you need is Bun: clone, install, start.
To talk to real models, open Settings and paste an OpenRouter key
(sk-or-…, from openrouter.ai/keys).
Packaged builds for macOS and Windows come out of CI today. Mac App Store and Microsoft Store releases are on the way, documented in PACKAGING.md.

support
keep the chorus singing
strophae is free, MIT licensed and built by one person in the open. If it saves you a stack of chat tabs, a donation keeps the columns streaming and the store releases coming.
Ko-fi takes one-off tips, GitHub Sponsors does monthly. Starring the repo and filing a good bug report are free and help just as much.
