Lantern Post launches free greeting cards with verified hidden reveals

PIGENAI LLC has launched Lantern Post, a free digital greeting card service that hides a verified song, video, story or place behind a glowing lantern. The product is designed to let people send a personal surprise without accounts, apps or recipient tracking.

Why it matters: - Lantern Post is trying to make digital greetings feel more personal than a text message or standard e-card. - The service combines surprise, verification and privacy in a format recipients can open without signing in or downloading anything. - Free sending and receiving removes the usual paywall for a shared greeting card experience.

What happened: - PIGENAI LLC announced general availability of Lantern Post on Sept. 8, 2026. - Lantern Post is available at lanternpost.app. - A sender can hide a song, video, story or place behind a glowing lantern. - The recipient taps the lantern to reveal the hidden content. - The service requires about three steps and roughly one minute to send. - Recipients need no account, no app and no installation.

The details: - Senders choose from cards for occasions such as birthdays, thank-you notes and hard weeks. - Each card includes original artwork and a two-part sentiment, with a hook on the front and a twist inside. - Senders can choose a card or type a word and let the composer find one. - Lantern Post lets senders add a line only the recipient would understand, plus a P.S. under the reveal. - Lantern Post does not write those personal words. - Senders preview the card exactly as it will arrive, including the song. - Every reveal is verified before it is hidden. - Verified reveals are resolved to their final destination, matched against a strict allowlist of well-known homes and screened with Google Cloud Web Risk. - Each tap checks the card again. - Senders share the link themselves by text, email, messaging app or QR code. - Lantern Post does not email the recipient and does not ask who the card is for. - Song cards include a 30-second preview on the card before the recipient opens a music service.

Between the lines: - The product is built around a privacy-first pitch: no recipient address, name or account is kept. - Lantern Post sets no tracking pixels and sends no read receipts. - The system counts only whether a card was opened and whether a lantern was tapped. - The privacy model is designed to make the card temporary only when a sender, recipient or forwarded recipient chooses to end it. - Cards have no expiration timer by default. - Recipients can forward a card and start one of their own with one tap. - That makes the product part greeting card, part lightweight sharing system for media and messages. - Founder Lindsay Hiebert said Lantern Post is meant to let one person hand another “a moment that was chosen, sealed, and verified — and completely free.” - The first Lantern Posts already include a card made for a Kansas City gate agent whose 4 a.m. kindness inspired the launch essay.

What's next: - Anyone can send a free digital greeting card now at lanternpost.app. - Readers can open a live example card the same way a recipient would. - Lantern Post says it will remain free to send and free to receive, with no membership fee and no paywall. - PIGENAI LLC is also positioning Lantern Post as part of a broader set of applications from founder Lindsay Hiebert, who leads the company and has backgrounds in AI governance, security, networking and education.

The bottom line: - Lantern Post is betting that privacy, verification and a playful reveal can make digital gifting feel more human without adding friction for recipients.
