Reading, tools and saving your work.
How the tools work, where your words are kept, and what to do before changing devices.
01What is ZEROINSIGHT?
ZEROINSIGHT offers reading notes and two kinds of thinking card to help you record a question, check its evidence and revisit a judgment.
02Are the tools free to use?
No. You can read the notes and open the tools without an account or payment.
03Is my card sent to a server?
No. The cards run in your browser and do not submit your input or call an AI service. To keep a copy, turn on browser saving or export a file.
04Will my text survive a refresh?
Only when you enable “Save on this device” and browser storage is available. Otherwise, export a file before leaving. Storage does not synchronize between browsers or devices.
05Can I change language and appearance?
Yes. Each language has its own pages. The language selector keeps the equivalent page, and light, dark, paper and system appearance options are available. Unsaved tool text should be exported before switching pages.
06Does this method guarantee a correct conclusion?
No. It helps organize questions and make assumptions visible. It does not verify evidence automatically, assign reliability scores, or replace appropriate professional judgment.
