Good to know
- 26 of 27 tools run entirely in your browser; the other one explains on its page what it sends.
- 25 of 27 keep working without a connection once loaded.
- Open Graph & Social Preview Checker: In “Page URL” mode the address is sent to MySmartCoPilot’s server, which fetches the page’s head and, if you leave it on, asks about the preview image (type, size, redirects). Your browser also loads the preview image from its own server to read its pixel size. In “Paste HTML” mode nothing is sent unless you tick the server image check.
- Social Post Accessibility Checker: Downloads a dictionary (for hashtag suggestions) and emoji names from MySmartCoPilot the first time they are needed; your post is never sent anywhere.
- Sentiment Analyzer: The VADER word list (about 140 KB) is downloaded from MySmartCoPilot the first time you analyse a text; opening a PDF downloads the PDF engine once. Your text never leaves your device.
- Results are estimates for planning and learning, not financial or legal advice. Check the method and assumptions on each tool’s page.
