Thousands of messages later, memory is not enough. Find when a subject came up and return to the original passage.

Three years of WhatsApp should not depend on your memory.
Reconstruct events, promises, changing accounts, and important moments scattered across thousands of messages—with a path back to what was actually written.
We are opening the first spots gradually.

You know it happened.
The hard part is reconstructing how.
“But you told it differently before.”
See related statements about the same subject at different times—without automatically treating one as true.
“What did we agree?”
Recover promises, dates, amounts, changes, and open points scattered through a conversation.
“When did all of this begin?”
Reconstruct how people, subjects, and events appeared over time.
You remember the feeling.
The conversation records what happened.
Trailon organizes the path between them.
How it works
- 01
Your conversation
A WhatsApp conversation can contain years of events, people, promises, and different accounts.
- 02
Reconstruction
Trailon organizes these elements over time and identifies relevant paths between them.
- 03
Path back
An interpretation should not replace the conversation. The path therefore ends at the message supporting the reading.
conversationcontextoriginal message
Trailon is not a lie detector.
A conversation can show that two different statements were made. It can show when a subject appeared, how an explanation changed, or what was agreed.
By itself, it cannot establish intent, guilt, or factual truth.
Trailon reconstructs what is in the messages. Interpretation remains human.
Fictional example
A story can change before you notice when.
- MARCH
“I did not even know that person.”
- JUNE
“I knew them, but we never met in person.”
- NOVEMBER
“We met once.”
It is not only about relationships.
Promises and agreements
What was agreed—and what changed afterward.
Payments and debts
Amounts, dates, requests, and revised arrangements.
Personal histories
Events scattered across years of conversation.
Professional conversations
Decisions, deliveries, and commitments made on WhatsApp.
Different accounts
What each person said and when.
A personal conversation deserves to be treated as personal.
We are building this experience for deeply personal material. Privacy, data deletion, and control over submitted material are part of the product architecture—not a later add-on.
