Built for messages
Two message sources. One review workflow.
Conversations are the heart of most modern cases. Evidence Locker turns phone chats and Slack workspaces into the same searchable, taggable, exportable review.
Phone messages
Cellebrite chat analysis
Upload the ZIP exported from Cellebrite and every chat, SMS and instant-message thread on the device becomes a searchable conversation — with its photos, audio, video and documents attached.
- Conversations grouped by chat, with every participant
- The device owner's messages identified on the right
- Attachments converted for in-browser preview
- Live progress from upload to validation to completion
Workplace messages
Slack workspace analysis
Upload a Slack workspace export and Evidence Locker rebuilds the workspace — channels, private channels, direct messages and threads — then fetches, hashes and preserves every shared file.
- Threads, reactions, edits, link previews and canvases
- Files downloaded from Slack and hashed (MD5, SHA-1, SHA-256)
- Validation notes for anything Slack could not serve
- Times shown in the case’s time zone
How it works
From export to production in four steps
- 01
Import
Drop in a Cellebrite report or a Slack export. Large uploads run in the background while you keep working.
- 02
Preserve
Messages and files are parsed, hashed and stored encrypted, with validation notes for anything missing.
- 03
Review
Search, filter and tag across every conversation with your team — attorneys, examiners and clients.
- 04
Produce
Export exactly what matters as RSMF for your review platform or as PDFs that read like the original chat.
Review tools
Find the messages that matter — fast
The same tools work across phone chats and Slack workspaces, so your team learns one way of reviewing.
Boolean keyword search
AND, OR, NOT, exact phrases and wildcards — across every message, file name and link preview.
Tag messages and threads
Tag a whole conversation, a single thread reply, or a file. Tags travel into every export.
Filter by people, dates and tags
Narrow every view at once — conversations, files and exports all honor the same filters.
Read it like the original
Day dividers, threads, reactions, edits and inline images, shown in the case’s time zone.
RSMF and PDF exports
RSMF for your review platform, or PDFs by chat, by day, or by exact criteria.
