How it works

Write in kardens

A notebook that's yours. Daily entries, topic notes, wiki-style links between them. Your thinking accumulates into a personal knowledge graph.

Get coached, not corrected

The AI reads what you wrote and asks questions that make you think. Over time, you start catching your own weak arguments before the coach does.

See your creative process

Provenance tracking shows what you typed, pasted, and got help with. Not a judgment — a mirror.

Questions

What does the AI coach actually do?

It reads what you wrote and asks you questions. It seldom rewrites your text — instead, it asks questions that help you revise. It's more like a writing tutor than an autocomplete.

How is this different from ChatGPT?

ChatGPT writes for you. Kardens makes you write yourself — then asks you hard questions about what you wrote. ChatGPT conversations disappear. Your kardens notebook accumulates into a knowledge graph.

How is this different from Turnitin?

Turnitin checks text after it's written and guesses whether AI generated it. Kardens tracks the writing process as it happens — so there's nothing to guess.

Does this replace Google Docs?

For writing practice and daily journaling, yes. For collaborative documents and spreadsheets — no. Kardens is purpose-built for thinking-through-writing.
