WRITE, HAND OFF AND FOLLOW UP — TOGETHER
Write in the same note at the same time. A line becomes a task, then goes to a teammate with a memo and a due date, and you see when they have seen and accepted it. To-dos and the project tree open that original line; the calendar opens its note.

Scattered thoughts, notes, tasks, messages, files, and dates come together in CommonNote. Product screens show a note becoming a next step, tasks gaining owners and due dates, and people working together beside the source.
THE THREAD, NOT ANOTHER TAB
A good note should not go quiet after it is written. CommonNote keeps the reason, the next action, the person, and the date attached as the work changes shape.
ADVANTAGES AT A GLANCE
The gaps people usually bridge by hand, between a notes app, a chat app, a to-do app and a calculator, are part of the default screens.
From a task in To-dos or the project tree, open the source line and you land on the exact line of the note where it was written; the calendar and schedule table open the note. No retyping across views.
How tasks work →Hand work over with a memo (300 characters) and a due date, and see whether it reached their screen and was accepted. Unseen handoffs get one follow-up after at least 4 hours, between 08:00 and 21:00 Korea time; long-unanswered ones are shown first when the app opens.
Hand off a task →On a checklist or list line, @tomorrow 3pm, @fri 5pm, or Korean forms like @금 5시 and @월~금 become due dates and ranges, read in Korea time.
H2SO4 shows as H₂SO₄, while lab codes like IC50, OD600, HeLa and H3K4 are left alone. The text itself doesn’t change, so search and copy still work.
Chemical subscripts →Type a formula to sum atomic weights instantly, or a name to look it up on PubChem, then work out molar mass, mass, moles and dilutions. Looked-up compound information is saved.
Reagent calculator →Combine several images into one figure with panel labels, a legend and automatic numbering — a paper figure draft, inside the note.
Figure frames →Finalizing stores that moment’s version with a SHA-256 hash chained to the previous signature, and colleagues can add witness signatures. Later edits to the body are flagged in the record panel.
Finalize a record →In review mode, comments sit in the margin beside the text and archive themselves once everyone who needs to confirm presses ✓. You can see whose ✓ is still pending.
Review mode →A workday morning digest (Korea time), and — while the Mac app is running, even with its window closed — the Today bookmark tab on the left screen edge and widgets show today’s work. iPhone widgets, Live Activities and Apple Watch come with the iPhone app, now on the App Store.

Open the guide →FOR THE WORK YOU DO
You keep asking who wrote what, and which version you reviewed.
Tell collaborators’ contributions apart by color, and keep reviewed versions with roughly 10-minute version history (the latest 50 versions overall, plus older versions used by finalized records and signatures), finalized records and witness signatures.
Finalize a record →You hop between a calculator, a figure tool and your notes, pasting results.
Chemical subscripts, a reagent calculator, figure frames, TeX math and conversion of ruled-table images all live inside the editor.
Research tools →You asked, but the context, deadline and confirmation are scattered.
Hand off with a memo and due date, then watch seen, unseen, accepted and declined in the Handoffs view. The dashboard collects overdue work and progress by person.
Follow up on handoffs →The same timetable and dates get retyped for every person.
Import Apple Calendar (.ics or a subscription link), exchange or request weekly timetables, and overlay teammates’ timetables to find when everyone is free. Recurring tasks arrive on the weekdays you choose.
Fixed weekly timetable →Lingering sign-ins and exposed personal records worry you.
See signed-in devices and sign them out remotely, use passkeys, and know that the server database stores only password and session-token hashes. Unshared notes can be password-locked and re-lock automatically.
Account security →The context lives in your notes; the deadline lives in another app.
Add @fri 5pm to a checklist or list line and it shows up in To-dos and the calendar; the morning digest and widgets bring today’s work to you.
BRING YOUR HISTORY. KEEP YOUR EXIT.
Folders come in as notebooks. Current notes go out in formats other apps can still read. CommonNote treats portability as a product feature, not a cancellation flow.
NEWS
Features, pricing, downloads, security, the guide and news in one place. Signed in? The address still opens your workspace directly.
The weekly timetable is easier to find, and you can now send it to a colleague straight from the editor.
Today stands out with a filled circle, weekday headers are lighter, and today's number no longer disappears on Saturdays and holidays.
