Chat export viewer
Open a ChatGPT or Claude export file and read it like a document.
What it does
Export files are large JSON archives that no ordinary program opens well. Drop the file here to browse conversations by date, search across them and print one as a clean page.
How it runs
The file is opened by the browser and stays on your machine. Nothing is uploaded, and the page holds no copy of your export after you close the tab.
The other tools
- Token counter: Count the tokens in a piece of text for the model you are about to send it to.
- Cost estimator: Turn a token count and a model choice into a monthly bill.
- Prompt improver: Rewrite a prompt against a checklist of what the model actually needs.
