Denker vs ChatGPT

AI on your screen, not in a chat window

Denker is a new interface for AI agents: instead of typing into a chat window, you point, draw, or talk on your screen, and Denker's agents see what you mean. They work across everyday apps like Gmail, Figma, and Sheets and bring the result back where you are. Coding work can run on your own Claude Code, Codex, or OpenCode. This guide compares the chat window, coding CLIs, and Denker so you can pick the right tool for work that lives on your screen and across your apps.

CONTEXT

The chat window tax: leaving work to get help

You are in the middle of real work when you need help from a chatbot. You stop what you are doing, open a new tab, start a new chat, then try to explain what you were just looking at — with copied text, screenshots, pasted links, and background the model never saw. By the time the answer arrives, you still carry it back yourself and redo steps where you work. That round trip is the tax of the chat window.

Every paste is a clue you left your work to get help.

DEFINITION

What Denker is

Denker is the new interface for AI agents. You hand off work by voice or text from the app where you are already working, circle what matters when pointing alone is not enough, and get answers where you are with the result on screen.

“Point at your screen. Your agents take it from there.”
The Denker homepage

No chat window. No copy-paste.

COMPARISON

Chat window vs coding CLI vs Denker

Three options, three places where the work happens:

Chat window: you leave your tab, describe the task in words, paste screenshots or files, then carry the answer back yourself.
Coding CLI: strong intelligence for code and terminal work — you pick the model that fits, using the login you already have.
Denker: you stay where the work already is. Point at what you mean, dispatch to Claude Code, Codex, or OpenCode, and the result comes back where you are working.

Chat holds the conversation, CLI holds the intelligence, Denker holds the work in place.

EXAMPLES

What it looks like on your screen

Three sample demos with invented data from the homepage demo:

Figma help: circle a button and ask how to make its shadow softer — Denker points to the drop shadow setting, guides Blur to 24, and confirms.
Gmail replies: three customer questions highlighted, a reply written for each, draft left unsent for review.
Cross-app follow-through: four receipts opened in Mail and copied into a Google Sheet totaling €511.78 — after pointer approval.

Point, circle, talk, review, then you send.

HONEST GUIDE

When chat still wins and when Denker fits

Chat still wins for quick standalone questions, brainstorming in words, or drafting from scratch when there is no screen context to show. If the answer does not need your tabs, inbox, or spreadsheet, staying in the chat window is faster. Denker fits when the work is already on your screen and spread across apps.

Quick words stay in chat, real follow-through stays on screen.

All follow-ups in these examples remain drafts for review. Denker asks before it moves your pointer, shows its cursor while it works, and never sends messages or emails on its own. Drafts wait for you to review and send.

Frequently asked questions

What is Denker?

How is Denker different from ChatGPT or a coding CLI?

Chat windows and terminals make you bring the work to them. Denker works on your screen and across your apps: point at what you mean, and the result comes back where you are working.

What kinds of tasks can Denker handle?

Denker works across everyday apps like Gmail, Figma, and Sheets and brings the result back where you are. Coding work can run on your own Claude Code, Codex, or OpenCode, which you can pick per task or run side by side.

How do I give Denker context?

Hand off work by voice or text, from the app where you are already working. Circle anything or just talk and Denker sees what you mean. The flow is Point. Dispatch. Get it back: point at your screen, pick Claude Code, Codex, or OpenCode and the model, and Denker answers where you are.

Will Denker act without asking me?

No. Denker asks before it moves your pointer, shows its cursor while it works, and never sends messages or emails on its own. Drafts wait for you to review and send.

What can Denker see on my screen?

Denker only looks at your screen when you invoke it, and only with the macOS permissions you grant. You can review or revoke those permissions anytime.

How does Denker work with Claude Code, Codex, or OpenCode?

Denker works with Claude Code, Codex, and OpenCode. Pick one per task, or run them side by side and follow their progress on your screen. There is nothing new to set up — Denker uses your existing CLI login.

How much does Denker cost and how do I start?

Free is €0 with 25 on-screen calls per month, 2 projects, and 5 connected tools, and Pro is €19 per month with unlimited calls, with a 14-day Pro trial and no credit card. AI provider charges are separate with a limited starter allowance. To start, download Denker, sign in, and hand off your first task by voice or text.
