I used Trailback to turn my Mac activity history into a daily work report with ChatGPT, then saved it to Notion. It helped me discover a practical new way to make use of my everyday work history.
Très bon travail. Je vais pouvoir profiter à fond de toutes les possibilités de cette intéressante application. Super !
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.
TrailbackNew · AI apps
Ask your AI app.
It asks Trailback.
Connect Claude, Codex or Cursor in one click. Then just ask, in the chat you already use:
find a file, see what you did yesterday, or write your day into Notion.
Claude
Found it. Invoice – Studio Nova – October.pdf, in your Downloads, saved on 14 October.

Codex
Yesterday you were at the computer for about 5 h 40 min:
- 9:10 Client proposal, in Word and Chrome (1 h 20 min)
- 11:00 October invoices, 3 PDFs and Gmail (55 min)
- 14:05 Website copy, in Notion and Figma (1 h 25 min)
Claude
Done. Added “Wednesday” to your Daily journal in Notion.
- Confirmed: pricing page edits, 2 client calls, October invoices sent
- Likely: “Website refresh” project
- Couldn't tell: 25 min in Chrome
Off until you turn it on. Trailback itself stays 100% offline; the AI app sends what it reads to its own service. How it works →
01 · Remember
Remember everything you saw.
Pages, files, screenshots and copied text, found by what was in them.
Remember · Describe it
Search in your language.
You remember what it said, not what it was called.
Type it the way you remember it, and Trailback finds it inside your pages, files, screenshots and copied text.
In English, or in nine other languages.
- Finds words inside PDFs, scans, spreadsheets, slides and screenshots
- Understands “from Gmail”, and “last week” in your language
- Accents optional: resume finds résumé
Pick your languages in Settings → General.
On Windows, reading words in pictures needs that language installed in Windows settings.
Remember · Browser memory
Every page you visit,
remembered.
Clear your browser history, and that page is gone for good.
The free Trailback extension saves every page you read to your computer, so you can find it later by what was on it.
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.
Remembered
Remember · Searchable computer history
Pick a time.
See what you were doing.
“I had that slide deck open
right before Thursday's call.”
Pick the time, and Trailback shows the pages, files and apps you had open.
One click opens them all again.
Your whole computer history, searchable by time: pick a moment and reopen everything from it.
- 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

You remember it came from WhatsApp,
not which folder it ended up in.
Trailback groups every file by where it came from, what it is and the project it belongs to.
Nothing is moved.
- 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 date is in a PDF somewhere: a policy, a bill, a passport scan.
Trailback reads your files and lists what's coming up.

Trailback reads each file and suggests a real name and a proper folder.

Loved by founders and builders.
Real posts on X.
Congratulations on the launch and wish you the best 🥳
finally a way to find that one pdf from three weeks ago without turning my office into a crime scene
Looks like a solid product. 🥂
Looks like a good product. Good use case. Curious what tool you used for the video generation
Consider me a fan! 🙋♂️
Congrats Pavan 👏 Trailback looks like a solid app. 🔥
Amazing 🤩🤩🤩
Macの中のファイルを探すのに使っています。日本語の検索とOCRに対応しているので、ファイル名を思い出せなくても、中身の言葉から探し出せます。ファイル名も勝手に変えず、提案を確認してから変える進め方なので安心です。購入前に開発者へ質問したときも、返信が早く丁寧でした。
In short
Trailback is a memory for your computer.
The Trailback app for Mac and Windows remembers what you did, so you can find it again by describing it.
On a Mac it is a Spotlight alternative that also finds web pages, screenshots and copied text by what was in them.
On Windows it is a Windows Recall alternative that works on any Windows 10 or 11 PC, without taking pictures of your screen.
What it does
- Remembers the web pages you visit (free extension for Chrome, Edge, Firefox, Brave, Comet and Safari), the files and PDFs you open, the screenshots you take and the text you copy.
- Reads the words inside PDFs, documents, spreadsheets, slides and screenshots, so you can search by what something said.
- Describe it: type what you remember, like “the invoice from the designer last month”, and it finds the file, page, screenshot or copied text.
- Quick Search from any app: press Option + Space on Mac (Alt + Shift + Space on Windows), find a file and drag it into an email or chat.
- Pick a moment: choose a time, see everything you had open, and reopen it all in one click.
- Your day, written up: connect Claude, Codex or Cursor if you want to, and they can write a short journal of your day. Or save a Day report for any day, in your own time zone.
- Works in English, Japanese, Chinese, Spanish, French, German, Portuguese, Italian, Dutch and Polish.
- A cross-platform digital memory app for Mac and Windows: the same app and the same features on both (each license is for one computer).
Privacy
- 100% offline. No cloud, no account, no tracking. Works with Wi-Fi off.
- Everything is stored encrypted on your own computer.
- Passwords, one-time codes and card numbers are skipped. Private and incognito windows are never recorded.
- You choose how long memories are kept, and you can delete anything.
- A private AI memory for Windows and Mac. It never records your screen or audio.
For Mac (macOS 13 or later) and Windows 10 and 11.
Pay once, every future update included, 7-day money back.
Questions
Something else?
Write to support@trailback.app.
The app
Is Trailback a Spotlight alternative?
Yes. Spotlight finds a file when you remember its name.
The Trailback Mac app finds it when you only remember what was in it, and it also finds web pages, screenshots and copied text. See Spotlight alternatives for Mac.
Is Trailback an offline alternative to Microsoft Recall?
Yes. Trailback is one of the offline alternatives to Microsoft Recall. It doesn't record your screen. It remembers the pages, files, screenshots and copied text you used, and keeps everything encrypted on your computer. Recall needs a Copilot+ PC; Trailback works on any Windows 10 or 11 PC and on Mac.
What app remembers everything I do on my computer?
Trailback. It's an app that remembers everything on your computer, offline: the web pages you visit, the files and PDFs you open, your screenshots and the text you copy. You find any of it by describing it in your own words.
Is there a private AI memory app for Windows?
Yes. Trailback is a private AI memory for Windows 10 and 11, from the Microsoft Store. Everything stays on your PC, with no account and no cloud.
Does it work with files in other languages?
Yes. Search works in English, Japanese, Chinese, Spanish, French, German, Portuguese, Italian, Dutch and Polish, including the words in screenshots and scans. Choose your languages in Settings → General.
Can AI apps like Claude, Codex or Cursor use my Trailback memory?
Only if you turn it on. In Settings → AI apps, connect Claude Desktop, Codex or Cursor in one click, and choose what they can see. Passwords, card numbers and your Private folder are always hidden. Trailback stays offline, but the AI app sends what it reads to its own service.
One good use: write your daily work journal from what you actually did.
Will it slow my computer down?
No. It works quietly in the background.
Which computers does it work on?
Mac (macOS 13 or later) and Windows 10 and 11. Trailback is a cross-platform digital memory app: the same app and the same features on both (each license is for one computer).

Can I move my license to a new computer?
Yes. Use it on any of your computers, one at a time.
Where do I get the Windows version?

Privacy
Is it recording my screen?
No. It remembers what you did (pages, files, screenshots you took, apps, copied text), never your screen or passwords.

Can I stop it remembering something?
Yes. Pause it, ignore any app, site or folder, or delete one item, a period, or everything.
