LetterLatch

LetterLatch is a mobile + web app for scheduling emotionally timed love letters and short notes that arrive when they matter: anniversaries, hard weeks, travel days, or “you’ll need this” moments. Users write letters, attach a photo or voice snippet, and choose a delivery trigger (date/time, location arrival, or a simple check-in like “after your exam”). The app includes lightweight AI assistance to polish tone (not generate fake feelings), suggest structure, and flag risky phrasing that could be misread. It also supports “offline drafting” so you can write when you’re emotional without sending impulsively. Recipients get a clean, distraction-free reading view and can save letters into a shared private archive. Monetization is straightforward: subscription for advanced triggers, shared archive, and voice attachments; free tier for basic scheduled sends.
