About the toolkit
Are all twelve tools free?
Yes. The three local AI tools and nine everyday utilities are free, without an account. AI tools download model files before first use.
Do you upload or store my files?
File processing runs in your browser. Files and document text are not uploaded. If you choose to share a verification link, it contains a SHA-256 fingerprint and byte count; full exports can contain filenames and your notes. AI processing runs on your device. When you load a model, your browser contacts jsDelivr and Hugging Face to download software and model files. Those services receive connection information such as your IP address; your selected files and text are not sent to them. Model files may stay in browser cache. Clear site data to remove the cache.
Which tool checks whether a file has changed?
File verification compares SHA-256 and byte count with a sender-provided reference. Text comparison checks extracted wording instead. Neither tool proves identity, delivery, acceptance or malware safety.
