My Day

The problem

You finish a week and cannot account for it. Your manager asks what you shipped. You open ahalf-finished document and spend ten minutes reconstructing why you opened it. You readsomething useful in March and cannot find it in August.

Meanwhile your AI assistant starts every conversation knowing nothing. You re-explain theproject, the file, the thing you already tried, every single time.

Your computer knew all of it and wrote none of it down.

What My Day does

Every ten minutes it writes one small Markdown file describing what you were doing:

---
start: 09:10
end: 09:20
title: Tracing the webhook retry loop
summary: You read Stripe idempotency docs, then edited retry.ts.
apps: Visual Studio Code, Google Chrome
sites: stripe.com, github.com
project: payments-api
---
- Reading Stripe's idempotency-key docs on retried deliveries
- Editing retry.ts, focused on the key-reuse path

That is the whole storage format. No database, no account, no upload. You can grep it,edit it, or delete a file you would rather not keep.

Install

npm install -g @abhitsian/myday
myday init      # explains exactly what gets read, then asks
myday start     # begins recording

macOS, Node 18 or later.

Want the menu bar app instead of the CLI? Build it in one command — it needs Xcode CommandLine Tools and takes a few seconds:

git clone https://github.com/abhitsian/myday && cd myday
./app/build-app.sh --install     # → /Applications/My Day.app

The app is signed ad-hoc rather than with an Apple Developer ID, which is why you build itlocally rather than downloading a binary. A downloaded copy would be quarantined byGatekeeper; one you compile yourself is not.

Removing it is one command and takes everything with it:

myday uninstall

How it works

flowchart LR
    A["Every 15s<br/>which app is in front"] --> D
    B["Your browser's own<br/>history database"] --> D
    C["Claude Code<br/>session transcripts"] --> D
    D["Every 10 minutes<br/>one Markdown note"] --> E["~/.myday/memories/"]
    E --> F["The app<br/>timeline, threads, friction"]
    E --> G["MCP server<br/>your AI assistant reads it"]

Three sources feed it, and you switch each one on or off separately. Reading your browsingis a different decision from reading your terminal work, so they are different switches.

It works before you grant it anything

Most tools in this category want an invasive permission before they show you anything, soyou have to trust them on a promise. Run tiers 1 and 2 for a week and read the output first.

For tier 3, myday build-helper compiles a 60-line Swift program that reads two attributesand prints them. You grant Accessibility to that one binary rather than to osascript,which would hand the same power to every script on your machine.

The timeline

Your day in order, with real application icons and clickable page links. Claude Code sessionssit on the same rail, each with a resume button that copies the command to reopen it.

Threads

A tracker tells you that you spent 1h55m in Slack, which is a fact about software. Threadstell you the checkout bug ran across four days and has been quiet since Tuesday, which is afact about your work.

Nothing is declared. There is no project field to fill in — threads are derived from thefiles you touched and the pages you opened. Each carries a state (today, yesterday, thisweek, quiet), and the ones you picked up and put down surface first.

Friction

The costs your day hides from you, each with the evidence attached:

• Signing in to the same host 29 times a week, which is a session-timeout setting rather than a habit
• The same search typed on 13 separate days, because the answer never got saved anywhere
• A page you navigate to most days and never bookmarked

Your AI assistant can read it

This is the part that changes how the tool feels. My Day ships an MCP server, so anyassistant that speaks MCP can look up what you did without you re-explaining it.

Claude Code — add to ~/.claude.json:

{ "mcpServers": { "myday": { "command": "myday-mcp" } } }

Cursor — add to .cursor/mcp.json. Windsurf, Zed, Continue and anything else withMCP support take the same two lines.

Then, mid-task:

You: pick up where I left off

Claude: You were tracing a double-fire in the webhook retry loop — you'd read Stripe'sidempotency docs and edited retry.ts, and retry.test.ts was still failing on theduplicate-delivery case (2026-08-14 15:30).

Four tools are exposed: history_search, history_window, history_resume, andhistory_time_by.

Notes are built from web page titles and window titles, which are text other people control.A page titled "ignore previous instructions" would otherwise reach an assistant that canrun commands. Every response comes back inside a fenced envelope with the brackets escaped,so the payload cannot break out of it, and the rule is restated on every single response.

Where this came from

OpenAI shipped Computer History in the ChatGPT Mac app in August 2026: record interactionevents rather than screenshots, roll them up every ten minutes into Markdown memory files,read those back when the user asks about past work. Windows Recall and Rewind had taken thescreenshot route before it and spent their public lives defending that choice.

The text-only decision is the good one, and My Day keeps it. Where the two part ways:

That last row matters more than it sounds. Threads need two or three weeks before they meananything, so a fresh install has nothing to say at exactly the moment you decide whether tokeep it. My Day reads the browsing history already on your disk and writes notes for the pastsixty days, so the first screen you see is populated.

Privacy

Rules apply before anything is written, so an app you exclude never reaches disk. There is nolater filtering step to get wrong.

myday permissions apps +Signal          # never record Signal
myday permissions sites include         # switch to an allow-list
myday clear hour                        # delete the last hour, notes and events both

Password managers are excluded out of the box. Private browsing is never included, becauseyour browser does not record it. Summaries are written locally with no model by default, andenabling one logs every send to a file you can read.

Clearing removes the notes and the raw events behind them. Deleting a note alone wouldleave the events on disk and the next rollup would write it straight back.

Commands

myday init | start | stop | status | uninstall
myday show | timeline | apps | browse | sessions
myday threads | friction | search <q> | ask "<question>"
myday sources | permissions | clear | backfill
myday view                       # the app, in a browser

What it does not do yet

• Window titles need a permission, so without tier 3 a note names the app and not the document.
• Threads bind 41% of consecutive notes. Continuous work still fragments more than it should.
• Nothing pushes. Every view waits for you to open it.
• macOS only. The capture layer is Cocoa and LaunchServices.
