The AI assistant
you always wanted.

Proton remembers everything about you, gets things done instead of just talking about them, keeps an eye on the things you care about, and can run whole teams of AI on complex tasks, all on your desktop.

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.

Real code.
Not prompts.

Most AI assistants are stuck in their own little world. They can talk about things, but they can't reach into yours. Proton can. With Skills. Search the web, read your files, book calendar events, send emails, control apps on your machine. Real things happening, not just words on a screen.

Skills can be written by you or shared with others. If it can be done on a computer, it can be a Skill.

web-search.skill.js
export const skill = {
  name: 'web_search',
  description: 'Search the web',
  parameters: {
    query: { type: 'string' }
  },

  async run({ query }) {
    const results = await searchAPI(query);
    return results.map(r => ({
      title:   r.title,
      url:     r.url,
      snippet: r.snippet
    }));
  }
};

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.

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.
