✔️ Do you have emails piling up in your inbox?
✔️ Do you love subscribing to interesting blogs and newsletters but don’t have time to read them all?
✔️ Are you dreading having to wade through dozens of emails to find the content you really want to read?

Introducing summE, a Gmail™ Add-on that instantly summarizes any email in your inbox with one click! summE uses ChatGPT to generate concise one-paragraph email summaries so you can quickly see which messages are important, interesting, or useful and disregard the rest.

summE’s unique functionality crafts each summary in the same voice as the message, so it feels like it was written by the sender, giving you a clear picture of the email’s content and style.

Add summE to your Gmail account today to start saving time and focusing on what matters most.

Scam Protection
scanE also protects you from phishing scams using a unique function that catches scam messages most spam filters miss. When it detects a scam message, scanE displays a warning for your security.

Introducing scanE, a Gmail™ Add‑on that instantly scans emails for AI‑generated content, so you know if your messages are legit.

scanE’s multi‑step process uses two layers of scans to calculate a score that’s over 97% accurate!

  1. scanE scans the message for common AI/scam elements, including phrases, formatting, punctuation, emojis, and email tracking.
  2. The Sapling AI Detector scans the message at the sentence‑level for tone, style, word choice, phrasing, and sentence structure.
  3. scanE averages the two scores to determine the final score, representing the likelihood that the message contains AI-generated text.

Scam Protection
scanE also protects you from phishing scams using a unique function that catches scam messages most spam filters miss. When it detects a scam message, scanE displays a warning for your security.

scanE empowers you to protect yourself from scams, spam, and misinformation by filtering AI‑generated content so you know whether you’re communicating with a bot or a real person.
