WindowsYour whole team runs on the plan you already pay for.
Log in with Claude, with Codex, or with both and pick per task. One flat fee, no API bill, no second subscription.
Built on Claude Code and Codex, within their usage terms. Not affiliated with Anthropic or OpenAI.
Watch them think, not just deliver.
The work isn't the file at the end — it's the room getting there.
Real roles. Real skills. One shared job.
These aren't personas with different labels. Each one carries hand-tested playbooks that have shipped real work. You don't hand out separate tasks and collect the pieces — you hand over a problem.
A team left alone will hand you something polished and wrong.
So a Founder sits on every job. It knows which teammate is doing what, and it steps in mid-work: debates a weak idea, rejects a draft that drifted, pulls the whole team back to what you actually asked for.
Not a promise of perfection. A teammate whose entire job is catching the drift before it reaches you.
“I built this because I'd become the blocker in my own company — the one person ten things waited on. I ran my real work through it for six months before letting anyone else near it. I didn't want advice. I wanted a team that would do the work, on my machine.”
Finished work. Not summaries of work.
Files you open and use — worked by the right mix of skills, checked by a Reviewer, kept honest by a Founder.
They notice how you like things — and remember.
Every time you ask for a rewrite, tighten a draft, or reshape a doc, your team is paying attention. It picks up your voice, your formatting, the way you want an email or a deck to land — and quietly remembers it. Nothing is hard-coded and nothing is generic. Over time, the team stops guessing and starts sounding like you.
Everything your team learns about you is stored on your device — never in the cloud, never with the model, never seen by us.
Your company stays on your computer.
Most tools ask you to hand your company to their cloud and pay monthly for the privilege. Antria runs where your work already lives, on an account you already have.
Battle-tested skills, built in.
Antria comes with embedded skills — playbooks that are battle-tested, verified, and already used by founders to ship real work. Most exist because of people who built in the open and shared. A few we lean on every day, with thanks:
…and the wider Claude Code and Codex skill communities — the design, research, writing, and planning skills we packed and learned from. Big thanks to all of you.
