Message Crawler

Built because chat data deserves a closer look before it ships.

Message Crawler is a Windows desktop application for processing chat and short-message data. Slack, Teams, WhatsApp, Cellebrite, Telegram, and dozens of other sources go in; RSMF, PDF, and DAT files come out. Between those two ends, you can actually look at the data, deduplicate it, normalize names, fix time zones, run keyword searches, tag and export — instead of treating chat data as a black box that funnels through unread.

Data sources supported

Message Crawler reads chat and short-message data from a wide variety of sources:

  • Chat platforms. Slack, Microsoft Teams, WhatsApp, Telegram, Discord, Zoom, Webex, MatterMost, Zoho Cliq, Lark, Meta Workspace, Facebook, Instagram, LinkedIn, ChatGPT.
  • Forensic and mobile-collection tools. Cellebrite, Oxygen, Axiom, Elcomsoft, ModeOne, Belkasoft, XRY, iMazing, SyncTech, Apple Chat.DB.

If your data is in a format not on this list, ask. Adding new sources is part of the regular development cycle.

View and inspect

  • Documents view. Every record in the database, in a sortable grid you can filter and sample.
  • Conversation view. See messages grouped into the conversations they belong to, with participants, dates, and message counts.
  • Native preview. Render attachments — PDFs, images, office files — without leaving the application.

Clean and prepare

  • Deduplicate records using the standard Bates approach or a custom hash on fields you choose.
  • Name normalize contacts so John Smith, j.smith, and Smith, John collapse into one identity. Original names are preserved so you can roll back any decision.
  • Time-zone convert message dates between source and target zones — including a "process in a different zone than the load file" workflow for multi-jurisdictional reviews.

Search and tag

  • Search bar Advanced searching capabilities based on metadata.
  • dtSearch keyword indexing for full-text search across message bodies and extracted text.
  • Tagging multiple modes: tag the document, the family, the conversation, the day, or a configurable range of messages around it.

Transform and export

  • Mass update, search and replace, date format, and renumber tools for bulk changes across a search.
  • Export select from RSMF, PDF, EML, HTML — or all of them at once. Induststry standard DAT file is also supported
