LoveLetter is an online service for discovering and sharing messages tied to a person’s name. Visitors can search using a name, nickname, or part of a name, then read letters and replies for free. The collection holds anonymous words that were left unsaid or written later, including messages of love, gratitude, apology, farewell, and reflection addressed to others or to oneself. Search results may include letters intended for someone with the same name, so the service encourages readers to approach them thoughtfully rather than assume they are personal.

People can also write and leave letters for someone who may find them in the future by searching their name online. Writers use a name or nickname rather than the recipient’s full legal name, and are encouraged to include shared memories or details that help the intended reader recognize the message. LoveLetter preserves the writing process alongside the finished letter. Readers may reply, but doing so requires the original writer’s full name.
