One agent, for every task

aixplain One does your work and builds agents and apps in plain language, on your desktop and in your browser, on any model.

Using Athena, which picks the right model for each step

Free for Mac, Windows and Linux

Hand it your work

It works in your apps and files, builds apps and writes code

Just ask

Ask in plain words and start from the outcome. It plans, connects what it needs and gets it done. It asks before it sends, pays or deletes, until you let it run on its own.

Desktop, the web, WhatsApp and Telegram

Works in your apps and files

It works with the files on your computer and the apps you connect: Gmail, Calendar, Drive and more, from 1,000+ tools, or your own MCP servers and APIs.

export async function POST(req: Request) {
  const { message, clientId } = await req.json()
  // The agent inside the booking app
  const run = await fetch(`${API}/v2/agents/booking-assistant/run`, {
    method: "POST",
    headers: { "x-api-key": process.env.AIXPLAIN_KEY },
    body: JSON.stringify({ query: message, session: clientId }),
  })
  return Response.json(await run.json())
}

describe("booking assistant", () => {
  it("moves a session to the next free slot", async () => {
    const res = await call("Move Thursday to Friday")
    expect(res.status).toBe("done")
    expect(calendar.events).toHaveLength(1)
  })
})

  })
})

Code in the app or your terminal

The same agent writes, tests and reviews code on your computer. In your terminal it keeps the same permissions and sessions.

Your agent factory

The same agent that does your work builds new ones. It designs, builds, tests and deploys each agent, then monitors and improves it, with evidence at every step.

Develop and deploy

Describe the work in plain language. aixplain One designs the solution with you and builds the agent, or you build it in code with the Agents SDK. It's tested on your machine, then deployed with its own API and key, versioned, on cloud or your servers.

Monitor

Every run is traced: what the agent was asked, each step, how long it took and what it cost. Set thresholds on latency, escalations and cost, and get an alert when one is crossed.

aixplain One

How did booking-assistant do this morning?

Read 214 runs since 8:00
Checked them against your thresholds

212 answered on their own. One refund was escalated, one bulk cancellation was stopped, and one run crossed the 3 s latency threshold, so you got an alert.

Analyze

See why runs end the way they do: the topics people raise, their sentiment, the error codes behind failures and the root cause of escalations.

aixplain One

Why are runs escalated?

Grouped this week's runs by topic and sentiment
Traced escalations to their cause

Most escalations are refunds over $200, which the refund policy caps. Calendar conflicts cause most errors.

Evaluate

Run the same agent on two models over a dataset built from your real runs, and score both on correctness, conciseness, coherence and safety.
