Autogenerating a Book Series from Three Years of iMessages

Original Article ↗ Hacker News Discussion ↗

Turning years of private chat logs into printed books sparks both enthusiasm and unease. Commenters trade tools and techniques for exporting and decrypting messages from iMessage, WhatsApp, Telegram, WeChat, and Signal, and explore ways to format texts, images, and even AI‑generated summaries or haikus into readable volumes. Alongside technical tips, they debate whether preserving intimate conversations as physical artifacts is a valuable form of personal and historical memory or an invasion of privacy that freezes moments people might prefer to forget.

Message Export Across Platforms

  • Several commenters want similar books for WhatsApp, Telegram, WeChat, Signal, etc.
  • WhatsApp:
    • Native export to text, with/without media, but limited to last 10k/40k messages.
    • Limits may be framed as email-size issues but some suspect it’s to slow migration to other services.
    • Backups are encrypted; tools exist to decrypt SQLite backups with a user-set password.
  • Telegram:
    • Has native JSON export, considered easy to adapt.
  • WeChat:
    • Export and decryption described as painful: emulator use, brute-force decryption over days, outdated HTML tools that break on some messages.
  • Signal:
    • One user struggles restoring an old Android backup; others suggest it should work or point to third‑party tools.

Preservation, Nostalgia, and Creepiness

  • Many find the idea deeply sentimental:
    • A way to preserve relationships, personal history, and correspondence akin to letters or diaries.
    • Compared to wartime letters and historical letter collections; concern that future historians will lack such records.
  • Others are uneasy or find it creepy:
    • View chats as closer to transient spoken conversation than letters.
    • Worry about immortalizing cringeworthy past selves.
    • Debate over whether private messages “should” be ephemeral.
  • Some explicitly embrace total recall and long‑term logging; others value forgetting for mental health.

Gifts, Services, and Practicalities

  • Many see strong potential as a gift (anniversaries, reminders of relationships, even toxic ones).
  • Some think it could succeed as a commercial service; others worry about sending highly private text corpora to printers.
    • Concerns include poor data security practices and indefinite retention at publishers.
  • Home printing and cheap comb binding are suggested as privacy‑preserving alternatives.

Media, Formatting, and Tools

  • Handling images, GIFs, and videos is a recurring gap; ideas include thumbnails, QR links, or LLM‑generated descriptions.
  • LaTeX is both praised for output and cursed for difficulty.
  • Several libraries and scripts are mentioned for exporting iMessage, WhatsApp, and others.

AI/LLM Enhancements

  • Multiple people initially expected an LLM‑generated narrative based on the chats.
  • Proposed augmentations:
    • Haiku or poetic summaries per exchange.
    • Monthly one‑line summaries for a richer table of contents.
    • Turning threads into plays, scripts, or novels.
  • Pushback exists against feeding intimate conversations into “randomness machines,” preferring to keep communication personal.
