Overnight Catch-Up: the WhatsApp card that never makes things up

Описание и применение

Приложение Overnight Catch‑Up преобразует длинный чат WhatsApp в короткую карточку, показывая упоминания пользователя, вопросы, сроки, деньги, ссылки и краткое резюме, уменьшая время чтения с 5,5 минут до 1 минуты.

Задача

Users miss overnight WhatsApp group chats with many unread messages, making it hard to find deadlines, questions, or important information.

Результат

The app reduces reading time from ~5.5 minutes for 300 messages to ~1 minute for the card, while ensuring privacy by not storing data and allowing local offline summarization.

Рабочий процесс

• Parse WhatsApp export (Android/iPhone)
• Extract facts: user mentions, unanswered questions, times/deadlines, money, links
• Summarize long chats in ~3,000‑char chunks using an open‑weight model
• Combine summaries
• Guard checks summary for new numbers, links, money words or unknown names; if rejected, show facts only

Доказательства

Plain Python finds mentions of my name, unanswered questions, times and deadlines, money and links, and copies them straight from the chat. No model is involved.

Источник

A guard rejects any summary that adds numbers, links, money words or names that are not in the chat. If it rejects, the card shows facts only.

Источник

The app estimates about 5.5 minutes to read the chat versus about 1 minute for the card (an estimate at 200 words per minute).
