What is LossyInfo?
LossyInfo is an independent research-and-tools project run by Sarah. Its free browser tools and source-checked Claim Ledger help people recover context lost in copying, compression, summary and retelling.
Every copy leaves something behind.
LossyInfo makes small tools and usable research for inspecting what information gains, loses, and quietly invents on its way to you.

Questions answered
What lives here—and when is it useful?
Three short answers. The detailed tools, evidence and creator scope stay where they belong.
How does the evidence work?
Each Claim Ledger entry links its source, states what the source supports and keeps a material limitation attached. Inspect the Claim Ledger, NASA-backed Mercury example and FAA-backed comet example.
What can a creator get?
Start with a €19 ready-made Mystery Fact Box or request a €49–59 Topic Box. When the subject needs deeper bespoke work, the Research Drop starts at €149. Already have a draft? The separate €49 Script Audit checks its factual claims.

Useful little probes.
Each tool answers one narrow question and keeps your files in your browser. The mix is intentional: the internet gets to tell us what deserves to grow.
Image tool 01↗
See exactly what JPEG compression throws away.
Compare quality and file size side by side, without uploading the image.
Inspector 02↗What does this image say about itself?
Inspect basic file structure and embedded JPEG metadata locally.
Calculator 03↗What was that money actually worth?
Translate U.S. dollar buying power across years using annual CPI-U.
Date tool 04↗How old was someone when it happened?
Calculate exact age at any event—years, months, and days.
Story tool 05↗Put the events back in order.
Build and download a clean timeline from scattered dates.
URL tool 06↗See what a tracking link is telling strangers.
Decode, explain, and remove common tracking parameters before you share.
Field note 001
Before you repost.
A fast, repeatable way to investigate a viral image without pretending metadata alone can reveal the truth.
How to verify a viral image when the original context is gone.
Seven checks, ordered from cheap and fast to slow and conclusive.
Claim Ledger · first four
The context is part of the fact.
Surprising claims checked against authoritative sources, with the qualification most likely to disappear when the story travels.
Astronomy 01↗
Can the Sun rise twice on Mercury?
Yes—from some locations. That last part matters.
Engineering 02↗What does the square-window story leave out?
A fatigue mechanism and a test that accidentally strengthened its specimen.
Measurement 03↗What defines a kilogram now?
Since 2019, not one special metal object.
Method 04↗Can a metric reverse the result?
The same fault surface, measured two legitimate ways.
Why this exists
The web is very good at preserving copies and very bad at preserving the conditions that made them meaningful.
“Information survives. Context doesn’t always.”
