Using Claude Code, Codex, and OpenCode with Denker
Denker provides the workspace, your AI CLI provides the intelligence.
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 shows what Denker adds in front of Claude Code, Codex, and OpenCode, how to mix them per task, and what each part costs.
What Denker adds as the interface layer
Denker is the new interface for AI agents. You hand off work by voice or text from the app where you are, Denker sees what you mean, and your CLI does the work across everyday apps like Gmail, Figma, and Sheets — the result comes back where you are. The flow is Point. Dispatch. Get it back.
Denker handles where and how work runs, your CLI handles the thinking.
Claude Code with Denker
With Claude Code, Denker acts as the interface layer in front of your configured provider account. Point at work on your screen and dispatch by voice or text. In the current homepage demo with invented data, the user circles empty space on a website and asks for a call-to-action. Denker creates the session; the user selects Open in Claude, and Claude Desktop opens the Code session that edits Hero.tsx. The website then shows the new Book a consultation button.
Keep Claude Code, add on-screen handoff and cross-app results.
Codex with Denker
With Codex, the pattern is the same. Stay in the app where you already work, point or draw to show what you mean, and talk or type the handoff. Denker dispatches Codex with that screen context and brings the result back where you are working. A proposed first task is turning selected research notes into a comparison report in a reviewable frame; inspect its sources and output before extending the task.
Codex intelligence, dispatched from the app where you already work.
OpenCode with Denker
With OpenCode, Denker adds on-screen handoff and cross-app follow-through to the setup you already use. Hand off work by voice or text, pointing at items on screen or circling them to show what you mean. A proposed first task is explaining a visible app error and preparing a scoped fix in a named repository. Review the changed files and relevant checks before treating the task as complete.
OpenCode power with point, draw, and talk context.
Pick per task and work side by side
You do not have to pick just one CLI forever. Pick one per task, or run them side by side and follow their progress on your screen — one agent on Figma guidance while another drafts a Gmail reply and a third helps with a Sheet. Denker routes each handoff to the CLI you chose.
Mix and match CLIs without changing where you work.
Subscription and cost honesty
Cost has two parts, kept separate:
- Denker: Free €0 (25 on-screen requests, 2 projects, 5 tools) or Pro €19/month (unlimited), with a 14-day trial and no credit card.
- Your provider: subscription or usage charges for Claude Code, Codex, or OpenCode are separate from Denker's app plan. Denker includes a limited AI starter allowance; connecting your own provider uses that provider's access and billing.
Pay Denker for workspace, pay your provider for intelligence.

Frequently asked questions
Which AI CLIs does Denker support?
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.
Do I need an API key?
An API key is not required when your chosen CLI supports your existing subscription login. Reuse an installed CLI and sign-in, or follow Denker's guided installation and login steps. Provider access, billing, and usage limits remain separate.
What does Denker cost, and what about model costs?
Free is €0 with 25 on-screen requests per month, 2 projects, and 5 connected tools. Pro is €19 per month with unlimited on-screen requests, projects, and integrations, plus knowledge graph memory, with a 14-day Pro trial and no credit card. AI provider charges are separate, and the included AI starter allowance is limited.
Where does work happen and how do I stay in control?
Denker works on your screen and across your apps: point at what you mean, and the result comes back where you are working. 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.
