ToolDeck is a set of small tools that run in your browser. Each card handles one task, such as counting characters or tidying up text. You can clear the small jobs that come up in the middle of bigger work, then get right back to it.
Pick a card. Solve one small thing.
How it works#
No account and no download. Each tool fits on a single page: open it, enter your input, and copy the result. ToolDeck is free and works in any browser on a computer or phone. Every tool also has a usage guide.
Your data stays with you#
ToolDeck has no accounts. By default, your input is processed in your browser and never leaves your device. Some tools need server-side processing. For those, your input is used only to run that tool and is not stored afterward. For details, see our Privacy Policy.
Fewer tools, kept with care#
ToolDeck isn't trying to be a collection of every tool imaginable. We focus on everyday tasks people actually need and keep the number of tools small. Each tool handles one task, and usage guides are available in both English and Japanese. Each new tool includes only the features its task needs, and the flow from input to result is designed with care before it's released.
Built with AI, decided by people#
We use AI when building ToolDeck, but people decide what to build, how it should feel, and when it's done. Before anything ships, we review every tool for usability and make final adjustments.
