A new way to make software
Build on your plan.
Koda gives you a place to shape an idea into working software. It runs on the Claude or ChatGPT plan you already pay for, so there are no credits to buy and no bill from us.

Start with what you know. Koda helps turn your choices into a clear plan, then gives you the tools to build and refine it.
Always-on judgment that shapes every response.
Gets on with it. Does the work instead of describing it.
Tidies as it goes. Edits what's there before adding more.
Tells you what changed, and asks before anything hard to undo.
Checks that things actually work before calling them done.
Uses Koda's own tools the way they're meant to be used.
The notes Koda keeps about how this project works.
Focused playbooks the agent uses when a task calls for one.
Confirm a page works by driving it in a real browser.
Built in
Good tools come with good guidance.
Koda plans, checks its work, and keeps the project clean while you decide where it goes.
See
Nothing disappears behind the chat.
Your files, documents, previews, and changes stay close. Open them as you work and see what your choices are doing.
You can see where you stand
Know how much of your Claude or ChatGPT plan you have used and when your hours return.
It remembers the project
A new conversation can pick up the decisions and context that matter without making you explain everything again.
Stay in control
Move carefully or move fast. You choose.
Review a plan before work begins, approve individual actions, or give Koda more room. Koda says what changed in plain words, and every change is saved so you can go back.
