New: for admissibility, jurisdictions (Brazil, UK, US, Portugal), and the big-picture workflow, start with the WhatsApp Evidence Guide. This post is the hands-on companion for building the actual report.
WhatsApp conversations can contain commitments, approvals, price negotiations, and promises. When a dispute arises, a neutral, structured summary can help a lawyer, mediator, HR professional, or insurance adjuster review the conversation more efficiently.
Turn this chat into organized, timestamped evidence.
Analyze your chatAn evidence report is not the same as a screenshot folder. It is an organised package that can make months of WhatsApp messages easier to review. This guide walks through how to prepare one while keeping clear limits on what the package proves.
This is not legal advice. It is a practical workflow for creating a WhatsApp chat report that is useful to professionals. What is admissible in your jurisdiction is a question for your lawyer.
A complete WhatsApp evidence report has three components:
The original export lets a reviewer compare a timeline and issues list with the source material. The timeline makes the conversation easier to read, and the issues list highlights topics to check. Neither the export nor the analysis verifies origin, completeness, or legal status.
This is different from handing someone a stack of screenshots: screenshots are often fragments, while a preserved export gives the reviewer more surrounding context to inspect.
You do not need a formal evidence report for every WhatsApp disagreement. You need one when the conversation will be reviewed by someone outside the conversation:
In all of these cases, the person reviewing the evidence was not part of the conversation. They need structure, not a raw chat log.
Need a readable starting point? Upload a copy of your WhatsApp export, then ask the analysis chat for a neutral timeline or an issues list. Keep the original ZIP separately.
Use WhatsApp's built-in export function, from inside the conversation itself. On iPhone, tap the chat name at the top and scroll to "Export Chat". On Android, tap the three dots at the top right, then More, then "Export chat". You will be asked whether to include media — select with media if the conversation contains voice notes with relevant agreements, admissions, or commitments.
The export produces a `.zip` file containing the full `_chat.txt` log and any media files. On iPhone, pick Save to Files and the archive stays on the phone, findable again in the Files app. On Android, WhatsApp never writes it to storage: the file is handed to the share sheet once, and whatever you tap there is the only copy that will exist. Samsung phones have a "Save as file" entry, sometimes behind "More", which puts the `.zip` in Downloads. On every other Android, send it to Google Drive. The Android file picker then lists Google Drive in its side menu, so you can pick the archive straight from there with no download.
Important details:
This is the step most people skip, and it is the most important one.
If authenticity or preservation is in question, ask a qualified professional how to handle the original. Keep it separate from working copies; file metadata and a stored ZIP alone do not authenticate the export.
A lawyer does not want to read 3,000 WhatsApp messages. They want a concise timeline of what happened, organized by date.
Upload the export to ThreadRecap and ask, in the chat that opens with the recap:
Create a chronological timeline of key events from this conversation. Include: agreements made, commitments given, payments discussed, deadlines set, changes requested, disputes raised, and any escalation. For each event: date, who was involved, what was said or agreed, and a short direct excerpt from the chat. Use neutral, factual language. End with: (1) open questions not resolved in the conversation and (2) information that appears to be missing.
The output is a structured draft that can serve as a readable layer of your report. Check each excerpt, date, name, and conclusion against the source conversation before sharing it.
Ask a follow-up question with a different focus:
List every disputed, contentious, or potentially relevant issue from this conversation. For each issue: what each party appears to claim, the messages that support each position, whether the issue was resolved or remains open, and any conditions or qualifiers attached. Mark anything uncertain as uncertain.
Separate requests can keep the timeline and issues review distinct. Use neutral wording, mark uncertainty, and check both results against the source conversation before providing them to a lawyer, mediator, or HR investigator.
For more on structuring these prompts, see the decisions extraction guide and the decision log template.
Combine everything into a single folder or document set:
Label everything clearly. Date the cover note. This is the package you hand to your lawyer, HR department, mediator, or insurance company.
In many disputes, the most important evidence is in voice notes. People say things in voice notes they would never type: verbal agreements, admissions, threats, price confirmations, promises.
Voice notes may contain relevant context. If they matter to the review, include them in the export and preserve the original audio alongside any transcript.
When you export with media and upload to ThreadRecap, compatible voice notes can be transcribed through OpenAI's audio transcription service and placed beside the associated export timestamp and sender label. Review every transcript against the original audio before relying on it.
This is particularly important for cases involving verbal commitments ("I guarantee it will be done by Friday"), informal agreements ("Let's split it 60/40"), or any situation where the spoken word carries weight.
Use this structure when assembling your final report:
Report header
Section 1: Chronological timeline
_(Paste the timeline output from ThreadRecap)_
Section 2: Issues and claims
_(Paste the issues list output from ThreadRecap)_
Section 3: Voice note transcripts
_(If applicable — note which voice notes were transcribed and their positions in the timeline)_
Section 4: Open questions
_(Unresolved points from the conversation)_
Appendix: Original export
_(Reference to the preserved `.zip` file)_

This workflow produces a well-organised review package for a WhatsApp conversation. It does not:
What it can do is make the conversation easier to review. Instead of handing over a phone and saying "scroll through this," you can provide a structured package alongside the original ZIP, so the reviewer can compare it with the source material.
Upload a copy of your WhatsApp export to ThreadRecap, review the initial briefing, and ask for a neutral timeline or issues list. Keep the original ZIP separate and check the result against the conversation before relying on it.
