Your AI plans, your own models, and the apps you already use.

What it does

Chat. Code.
Agents on call.

Three ways to work, one app. Switch whenever you like; your files and history stay put.

CHAT

Hand it your files.

Drop in PDFs, spreadsheets and Word files. Get answers, charts and finished documents back, saved in a folder you can open.

CODE

Your coding tools, side by side.

Claude Code, Codex and others run in real sessions, each on its own branch. Every change is shown and checked before it's done.

AGENTS

A team, and a schedule.

Give one objective and a team splits it up. Or say "every Monday at 8" and it runs on time, then tells you how it went.

Accounts

Every plan you pay for.
One app.

Sign in to each Claude Code and ChatGPT account you have: work, personal, a client's. Pick which one each conversation uses.

01
Their sign-in, not ours.Each account signs in through Claude Code's or Codex's own login, in a folder of its own.
02
See what's left.Every account shows how much of its usage window is used and when it resets.
03
A limit is a choice, not a dead end.Wait for the reset and IJ picks up by itself, or carry on with another account you own.

Privacy

Built for work you
can't be careless with.

IJ was built inside an accounting firm, for client documents. No IJ account, no IJ server, nothing to sign up for.

On your PC

The app, your files and your history live on your computer.

Local only, one switch

Keep a chat on this PC or your own network. IJ asks before anything would leave it.

Asks first

You choose how much it may do alone, from asking before every action to only before risky ones.

Honest receipts

Every answer says which model wrote it, what it did and what it changed.

Undo

Files it writes and settings it changes come with an Undo button.

Remembers, openly

Tell it once how you like things done. You can see and edit everything it keeps.
