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

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

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.

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

  • 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

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

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
