Your own AI.
Everywhere you are.

1onE remembers what matters to you, reminds you about everything, does exact maths, makes images, writes, teaches and fixes your code. On your phone and your computer.

Free to start. No credit card, no invite code.

One assistant. Every kind of work.

Pick a skill, or just ask. 1onE switches to the right one.

Exact maths

Loans, savings, percentages, statistics and equations, worked out with a real calculator, not guessed.

Images

Logos, posters, product shots and illustrations from a sentence. Save them straight to your phone.

3D and animation

Describe a scene and get a ready-to-run Blender or Three.js script, with steps to render or animate it.

Writing

Emails, proposals, posts and CVs in your voice, tightened and proofread.

Business

Pricing, cash flow, pitch decks, plans and contracts explained plainly.

Study

A patient tutor that explains step by step, then quizzes you so it sticks.

Translate

English, French, Yoruba, Igbo, Hausa, Pidgin, Swahili and more, with the tone kept.

Code

Reads your whole project, explains bugs in plain English and fixes them when you say so.

Reminds you about everything.

Say it the way you'd say it to a friend. "Call Mum at 6pm." "Drink water every 2 hours." "Ade's birthday 12 March, every year." "Board meeting Friday 10am, remind me 15 minutes before."

1onE rings as an alarm on whichever device you're using, and emails you if you miss it.

Shows you the bug before it touches your code.

Paste your code, and the error if you have one. 1onE explains the problem in plain English and checks its own fix before showing it to you.

Nothing changes until you've seen the before and after and chosen "Use fixed code".

Remembers what matters to you.

Tell it once: "remember that Tolu's birthday is 14 May." From then on every answer knows it, in every chat, on every device.

Your tasks, habits and notes live in one place, and your day can be planned for you in a single tap.

Learns how you work.

Mark a good answer, correct a bad one, accept a fix. Each one becomes a lesson. On a Mac, 1onE can train its own copy of its brain on your lessons, privately, on your machine.

Private by design.

Your data is yours

Every account has its own separate storage, and everything travels encrypted. We never sell data or use it for ads.

Secrets stay out of the AI

API keys and private keys are stripped before anything reaches the AI, and contact details in your saved notes stay out of it.

Delete it all, any time

Delete your account in Settings and everything in it is erased. Backups roll off within a week.

Lost your phone?

Sign in on any device with your email or username. Reset your password by email.

Get 1onE.

Free during the beta. One account works everywhere.

In the terminal

Chat, ask about a file, or set a reminder without leaving your terminal.
