More than a name

Proton stands for Personalized Responsive Omnipresent Task-Oriented Network, and every word is intentional.

P
Personalized
Builds a living memory of who you are: preferences, projects, decisions. and gets smarter over time.
R
Responsive
Always ready when you need it. Type a message, say the word, or let Proton kick in on its own when something happens.
O
Omnipresent
Desktop, phone, Telegram, or any browser on your network. Always there, wherever you are.
TO
Task-Oriented
Doesn't just answer questions. It actually does things. Browses the web, writes files, sends emails, sets reminders, and more.
N
Network
When a task is too big for one AI, Proton splits it across a team of specialist AIs that all work together.

Know-how,
and hands.

Skills are natural-language instruction files that teach Proton how to do specialized work: polish a document, build a spreadsheet, process a PDF, design a deck, or follow your team's internal workflow. They give the model reusable expertise it can load exactly when the task calls for it.

Tools are Proton's real capabilities: searching the web, reading files, running terminal commands, controlling apps, sending messages, generating images, and more. Skills provide the method. Tools perform the action.

pdf-tools.tool.js
module.exports = {
  name: 'merge_pdfs',
  description: 'Combine PDFs into one file',

  async run({ files, output }) {
    return await mergePdfFiles(files, output);
  }
};
pdf-document-processor/SKILL.md
---
name: pdf-document-processor
description: Merge, organize, and polish PDF files.
---

When asked to combine PDFs:
  Review every source file first.
  Put documents in the requested order.
  Use merge_pdfs with the final file list.
  Save the output with a clear name.
  Open the result so the user can verify it.

Context,
on demand.

Every project has its own knowledge base: goals, stack, decisions, notes. Switch projects and Proton instantly knows exactly where you left off, without you re-explaining anything.

Proton also writes to the project file proactively, documenting decisions and keeping context up to date as you work. Your projects remember themselves.

Send Proton
on a mission.

Some tasks are bigger than a chat reply. Turn them into Missions and Proton keeps working in the background: researching, reading files, running tools, checking results, and moving through a clear plan step by step.

Mission Control lets you watch progress in real time: the objective, briefing, plan, timeline, files, monitoring, and every action Proton takes. While the mission runs, you can keep chatting normally, start something else, or come back later to inspect the work.

Proton watches.
So you don't have to.

Signals are like a personal lookout that never sleeps. Set one up to watch anything: a website, a price, your computer's health, an online service. When something happens, Proton doesn't just send you a notification. It does something about it.

CPU spiked? Proton diagnoses it. A competitor changed their pricing? Proton sends you a summary. If it can be checked, it can be a Signal.

One task.
A whole team on it.

Electrons are specialist AIs that each have one job and the right tools for it. When a task is too big or complex for one AI alone, Proton sends it to a whole team of Electrons working at the same time. Faster, more thorough, and better quality than any single AI could manage.

Atoms are pre-built teams you configure once for a specific type of work. Set it up once, reuse it forever.
