ULTRASSISTANT

A private assistant for research, writing, learning and building. It is being developed step by step, and this page only lists what actually works.

Live info

The platform

Built to stay small

Features switch on only when they are finished and tested.

Free models

Chat runs on an open-source model through Cloudflare Workers AI and its free daily allowance.

Private by default

Every message needs your owner passcode, so strangers cannot use your quota.

Light on phones

No frameworks and no heavy effects, so it stays fast on low-end Android devices.

Honest status

No invented uptime figures. If something is not built, the page says so.

How it works

Simple on purpose

  1. 01

    You write a message

    Your chat history is saved in this browser only.

  2. 02

    Your backend checks the passcode

    It also validates the request and checks the daily usage estimate before anything runs.

  3. 03

    A free model replies

    If the daily safety limit is reached, you see a message instead of a charge.

What works today

Written by hand, so it reflects what has been built and tested, not live monitoring.

Questions

Good to know

Is it really free?

It is designed to use free tiers only. Chat uses the Workers AI free daily allowance, and on the free plan going over it causes errors rather than billing. Free terms can change, so this is not a permanent guarantee.

Is my chat private?

History is stored in this browser only. Each message is sent to your backend and processed by a model on Cloudflare Workers AI.

Why a passcode?

It stops other people from spending your free daily quota.

How accurate is the usage number?

It is an estimate based on text length. Cloudflare's own dashboard is the real meter.

Does it remember me across devices?

Not yet. Shared memory and accounts come in later phases.
