Home/Products/Field Notes Companion
Mialink Software LLC · Chrome and Edge
Field notes that live where the work happens. Pin notes to the fields, columns and labels of any web application — hover to read, click to edit. Your notes stay in your browser, never in the app's records.
Field Notes Companion 1.5.0 runs on Chrome and Edge for Windows, macOS and Linux. Store listings are being prepared; until they are live, this page and the privacy policy are the reference for what the extension does and how it handles your notes.
Features
Most annotation tools mark a spot on a screen. Field Notes Companion attaches to the thing itself — a field's id, a label's target, a column header's text — and finds it again on every page load.
Field labels, column headers, section legends, plain text. If the page names it, you can pin a note to it — and the marker is re-resolved against the live page, so a note written next to "Renewal date" is still there after the app ships an update.
A small marker sits beside each annotated element. Hovering opens the note after a delay you set, from half a second to thirty seconds, and long notes open into a wider layout instead of a cramped tooltip.
Everything is kept in your browser's extension storage. Nothing is written into the application, so you cannot corrupt a record, break a form, or leave a note where a colleague will read it over your shoulder.
Bold, italic, underline, highlights, text colour, bulleted and numbered lists, links, and note, warning and example callout blocks.
By default a note follows the exact page you wrote it on, with long IDs and GUIDs in the address normalised so the same screen still matches. Turn on Ignore URL and match on screen and the note follows you across every account, ticket or order.
Choose the marker shape, its colour, the note background, a size from 8 to 22 pixels and an opacity, and override any of it per note. If you make them too faint to find, one button resets every marker to its defaults.
Export a dated JSON file, then restore with a merge or a clean replace. A reminder nudges you every 14 days by default, and you can change the interval or silence it.
Deleting a note records a tombstone with a timestamp. That is what stops a sync bringing back a note you removed on another machine, or an old backup quietly resurrecting everything you have deleted since.
If the target is not on screen — a tab you have not opened, a collapsed section, a field hidden by permissions — the marker is simply not drawn. No orphaned markers floating over empty space.
Notes are only ever read to the extent needed to find the element they are anchored to and draw the marker. There is no model, no summarising and no suggestion engine behind any of this.
Screens
Screenshots are being captured for the store listings. Until they land here, the two views below are the ones worth showing.

Storage
There is no account with us, because there is no service to sign into. Notes live in your browser's extension storage. If you want two machines in step, the extension can write one file to your own Google Drive — after you turn that on and sign in.
Drive sync uses the drive.file scope, which lets the extension see only the single file it created. It cannot read, list or modify anything else in your Drive.
How many notes are coming in, how many changes, deletions and conflicts, before anything is written.
It checks on the interval you set, and when two versions disagree it pauses and asks instead of picking a winner.
One at a time, with your choice of which version wins, and nothing silently resolved.
Honest limits
Worth saying plainly, because it decides whether this is the right tool for the way you work.
Chrome and Edge on Windows, macOS and Linux. There is no mobile browser support and no Safari or Firefox build.
No real-time sharing, no comments and no team workspace. You share notes by exporting a set and sending the file.
If an app draws its interface into a canvas or hides everything inside a shadow DOM, there may be no field id, label or header for a note to attach to.
Sync moves notes between machines through your Drive; it is not a live connection. Notes are stored unencrypted in browser extension storage and in the Drive file, protected by your OS account and your Google account respectively.
No account, no telemetry, no servers of ours. Uninstall the extension and its local data goes with it; delete the Drive file and the synced copy is gone.
