Trailback to everything
you did on your computer.
Websites you visit, files you open, screenshots you take, text you copy.
Trailback remembers it all. Describe it, and you're back.

Trailback gathers each piece of work by itself. You don't file anything.
Your browser history, kept
Every page you visit,
remembered.
Works in the browser you already use. Add the free Trailback extension to your browser in one click. It saves the pages you read to Trailback on your computer, so you can find them by what was on them, even after you clear your history.
On your Mac or Windows PC.
Trailback shows you the one-click link for your browser.
Pages are remembered quietly in the background.
Private windows are never recorded. Nothing goes to a server.
Why Trailback
Your computer does a lot.
It remembers very little.
The page, the file, the thing you copied. You saw it, you used it, and now it's gone.
01 · Describe it
Say what you remember.
You're back.
You know what it was about.
You just don't know what it was called.
Type it the way you'd say it to a friend. Trailback looks inside your pages, files, screenshots and copied text, and shows the best match first.
- Reads the words inside PDFs, documents, spreadsheets, slides, pages and screenshots
- Understands “last week”, “from Gmail” and “the pricing page”
- Works in English, Japanese, Chinese, Spanish, French, German and more
New in 2.7 · Media Tools
Add a background.
Ready to post.
Screenshots and screen recordings look better on a clean background.
Drop in any picture, screenshot or video. Pick a background and a size, and save it, ready for X, LinkedIn, Instagram or your website. All on your computer, and your original is never changed.
- Gradients, colours, a blur or your own picture
- Moving backgrounds for videos, with the sound kept
- 16:9, 1:1 or 9:16, and a Mac window frame


Also new in 2.7
Search in your language
Japanese, Chinese, Spanish, French, German, Portuguese, Italian, Dutch and Polish. Words in screenshots and scans too.
Spreadsheets and slides
Excel and PowerPoint files are found by the words inside them, not just their names.
Text, PDF and Media Tools
Every tool now has its own place in the sidebar, so the one you need is one click away.
Tidy names more files
Any PDF, document or screenshot called scan_0412 gets a real name from what it says inside.
Pick your own shortcut
Choose the keys that open Trailback from any app. It tells you if they are already taken.
Browsers that stay connected
Chrome, Edge, Brave and Firefox keep sending pages, and Fix Connection tells you exactly what to do.
Quick Search · from any app
Two keys. Find it.
Drop it where you need it.
Attaching the signed rent agreement. Let me know if anything's missing.

02 · Collections
Your files, sorted
the way you remember.
You remember it came from WhatsApp.
Not which folder it ended up in.
Collections sort every file by what it is, the app or site it came from, and the project it belongs to. Nothing is moved, so your folders stay exactly as they are.
- By source: everything from WhatsApp, Gmail, Drive or ChatGPT
- By type: invoices, contracts, screenshots, photos
- By project: one click turns it into a real folder
The site each download came from
158 files · photos, PDFs
64 files · attachments
38 files · shared docs
34 files · images, exports
Your projects
03 · Tidy
Messy files, sorted.
Only when you say yes.
“download (3).pdf”, “IMG_4823.HEIC”,
“Untitled.docx”. Sound familiar?
Trailback reads each file and suggests a real name and a proper home. Nothing changes until you click, and Undo puts it all back.
- Real names from what's inside each file
- Finds ID scans and bank statements lying around, and keeps them safe
- Shows the space you can get back: copies, old installers
Give 23 files proper names
Suggestions only. Everything can be undone.Rename all4 ID scans sitting in Downloads

04 · Your week
See where your week went.
Then share the good parts.
Busy all week, but can't say what you got done?
Trailback puts your week together for you: the projects you worked on, the files you made and the pages you read. It stays private on your computer until you choose to share it as a picture.
- The projects you worked on, in one view
- New files and pages read, counted for you
- Share it as a picture, or keep it to yourself
You worked on 8 projects this week.

05 · Pick a moment
Pick a time.
See what you were doing.
“I had that slide deck open
right before Thursday's team call.”
Pick any hour of any day. Trailback lays out the pages, files and apps from that time, in order, and opens them all again with one click.
- Ask “yesterday afternoon” or “last Friday at 3”
- See what you worked on, and for how long
- Reopen everything from that time in one click
