Everything you need. Nothing to set up.
Capture a thought, put related things underneath it, and open any line as a page. The same simple building block holds a shopping list or a whole project.
Put things under things.
Structure appears as you write it. Rearrange it whenever you like.
Start small, grow without limits.
Write a line. Put the details under it. When a line turns into a project, open it as its own page and keep going. Nothing is ever too big for a list, because a list can hold lists.
Click any bullet to open it as a page; breadcrumbs take you back.
The same item in every place it belongs.
Put the launch checklist under the project and under today. It is one item, not a copy: tick something off in either place and it is done in both.
A diamond bullet marks an item that lives in more than one place.
Done means gone — until you want it back.
Finished items fade out of the way so the list only shows what is left. One click brings them back when you need the record.
⌘Enter completes an item; the eye icon in the header shows or hides completed ones.
Tag it, name it, find it all at once.
Write #draft on a post, #blocked on a task, @sam on anything Sam owes you. A tag needs no setup and lives in the line itself, so the same word can label a note, a task and a plan. Click it and everything with that tag, on every page, lines up in one list.
Type # or @ in any line. Click a tag and the header search fills with it, listing every line that carries it across all your pages.
See the day you actually have.
Tasks next to meetings, on a page that exists for every day.
Block time by dragging a task onto your day.
See your tasks beside your meetings and set aside time for the work. A date on a line also brings it onto that day’s page.
Calendar events are shown, not changed. Nothing goes into your calendar unless you choose to add it.
- A page for every day.Today is one tap away; a strip of days lets you hop back and forward.
- Give anything a time.Drag an item onto the timeline; drag the block to move or resize it.
- Your Google Calendar beside it.Today’s events appear on the same timeline, in their own colours. Nothing goes into your calendar unless you add it.
- Move to today, tomorrow, next week.From any item’s menu. Nothing is ever marked “overdue”.
- Dated anywhere, found on the day.Any line with a date shows up on that day’s page, under Elsewhere.
Get it out of your head.
Every line is a note. Every note can hold more.
A journal you’ll actually keep.
One shortcut opens today’s entry from anywhere. Write a line, or three. Anything you date shows up on that day, so the journal and the calendar tell one story.
Ctrl+J starts today’s entry with the date already in place.
- Write anywhere.Every line is a note; a longer note sits under any line (Shift+Enter).
- Photos and files.Paste, drag in from your desktop, or attach from the menu. Images show right in the list.
- Share from your phone.Share a link or a thought into Nested List and it lands in today’s journal entry.
- Dates in plain words.Type a date and it becomes a chip that links to that day.
Remember everything.
Your second brain: everything you ever saved, one search away — even the things you forgot you kept.
Everything you save comes back.
Search for the words you remember. PDF text is searchable, and search by meaning and reading your photos give you more ways to find what you saved.
- The words you wrote, even with typos.
- What you meant, not just what you typed.
- The text inside your PDFs and documents.
- The text in your photos and screenshots.
- What is in the picture.
- File names and the notes on files.
Press ⌘K anywhere. PDF text is read on your device. Reading photos and search by meaning use AI and are on from the start. One switch in Settings, “Allow sending to AI models”, turns all AI off on every device.
Link ideas, and see what links back.
Connect a note to any other note as you write. Each item shows what links to it, with the path it lives under, so an idea is never stranded.
Type [[ to link to any item. Backlinks are one click away in the item’s menu.
Your files live next to your notes.
Drop in photos, PDFs and documents. They stay with the note they belong to, open in place, and the text inside your PDFs is searchable — photos too, once you turn that on.
Paste, drag in from your desktop, or attach from the menu.
- Filter the page you are on.The search box in the header narrows the current page in place, keeping the structure.
- Pin a search.A view you keep coming back to can live in the sidebar.
- Search inside PDFs and photos.PDF text is read on your device. AI reads the text in photos and what is in them, unless you turn it off in Settings.
- Typos welcome.The palette is fuzzy; “Close match” tells you when it forgave one.
Everything moves.
Pin, drag, fold, undo. The structure is never fixed, and nothing is ever lost.
- Undo everything.Every change is undoable, and undo puts the cursor back where it was.
Yours, on every device.
On your device first, in the cloud second, and always exportable.
- Works offline.Everything lives on your device. Changes sync when you are back online.
- Every device, one list.Phone, laptop, work machine. If two devices edit the same line, both versions are kept.
- Install it like an app.From your browser’s menu, on desktop and phone.
- Light and dark.Follows your system, or pick one.
- Never shared, never used to train AI.Your notes and files are yours alone. Nobody reads them, nobody trains a model on them.
- Export everything, any time.One backup file, or a folder of Markdown documents with your attachments.
The details.
Numbers and formats, for people who like to know.
Size and speed
Tens of thousands of notes still open instantly. A list that size is usable in about a third of a second, a keystroke lands in a few hundredths, and scrolling stays smooth because only the rows on screen are drawn — this year and in ten years.
Files
2 GB of file storage, up to 500 MB per file. Images, PDFs, audio, video, text and code all get a preview; PDFs open in place. Photos from an iPhone, ProRAW included, are converted on the way in.
In and out
Import: OPML, the format most outliners export. Export: one JSON backup with every item, or a folder of Markdown documents with attachments — the layout Obsidian expects.
Privacy
Your data is yours. It is stored safely, never shared with anyone, never used to train AI, and you can export all of it at any time.
Everything on your mind, in one place.
Open Nested List, type your first line, and put the next thought under it. That is the whole setup.
