1Build a living memory

Write today, find it forever

Today in Pompom at full length: Wednesday's daily note, with a morning run, a reading group, a line in Chinese, links to other notes, a quotation, timed tasks with reminder bells and an evening line about tea. Beside it, Do with the day's schedule and two overdue tasks, the backlinks with the passage that links here, a small map of the notes around this day, an unlinked mention in the half-marathon plan, and the note's history.

Today: the day's note, its tasks, what links here, what mentions it, the notes around it and its history.

  • Today is where you writeNow

    Each day has its note. Write without deciding where anything belongs. Links, tags, quotes, English and Chinese, and tasks with a time that remind you, all live right in your words.

  • Plain files, with their whole historyNow

    Every note is a markdown file in a folder you choose. Every version is kept, so nothing you wrote is ever lost.

  • Capture from anywhereComing

    Clip a web page, keep a screenshot, share from your phone, drop a PDF. Each arrives titled, tagged and summarised, and waits for your yes.

  • Filed for you, by referenceComing

    Pompom offers to show what you wrote today in the notes it belongs to, without cutting it out of the day it happened.

2Learn from experience

Learning you can inspect

LEAP is the learning layer beneath Pompom. From what you write, decide and ask, it proposes what you might have learned. Nothing becomes knowledge until you say so.

  • Beliefs as notesComing

    What you have learned is kept as ordinary notes: the claim, how sure you are, where it applies, and the evidence behind it.

  • Always with the whyComing

    Every belief keeps the passages that support or contradict it, and the record of how and why it changed.

  • Your view, over timeComing

    Ask how your view of something has changed, and see the moments that changed it.

  • Forget on requestComing

    Stop learning from a source, or erase it everywhere, after seeing what depends on it.

3Connect the dots

Everything you know, at a glance

A researcher's notebook: robot learning, a half-marathon plan, film photography, Sichuan cooking, Sunday calls home. Pompom found each topic and named it, with no folders or tags needed.

The map alone: about twenty coloured clusters of notes, each labelled with the topic Pompom gave it, joined by fine lines where notes link across topics, with a small group of loose notes to one side.

A map that answers questions

Most graphs are a pretty tangle. Pompom's map tells you something: which topics you write about, which ones never touch, and the notes that tie them together.

“DreamerV3 and Half marathon plan never meet: no link joins them.”What this shows, beside the map
The Graph with Where topics meet chosen: the notes that link one topic to another are lit in their topic's colour, the rest are faded.

Topics, named for you Now

Notes grouped by what they are about, each group named in whichever language you wrote it.

Ways in Now

Notes standing alone, ones you have not touched lately, the most connected, where topics meet, what has grown this month.

The map through time Coming

Slide back through the months and watch your topics appear, grow and join.

Every note, in its neighbourhood

  • Set like a well-made pageNow

    English, Chinese, or both in one sentence, maths, code and diagrams, all read beautifully.

  • Links both waysNow

    Beside every note: what links here, what mentions it without a link, and a small map of what is around it.

  • Related notes, suggestedComing

    Pompom notices notes about the same thing and offers the link, in blue and dashed, until you accept it.

4Think and decide better

Ask your own notes

  • Answers that cite youNow

    Ask in plain words. The answer is drawn from your notes and points to each passage it used.

  • Search as fast as you typeNow

    Results with every keystroke, in English and Chinese, forgiving of typos.

  • Keep what you learnComing

    Save an answer as a note, or turn it into a timeline of how a question unfolded.

  • Contents that knows the noteComing

    Long notes get a contents column that folds, filters and picks up where you left off.

Design for Ask: an answer about sim-to-real drawn from three notes, each cited by number, with Save as a note, Turn into a timeline page and Copy, and a line saying which notes were sent and that private notes were left out.

Design for Ask: the answer with its sources, and what is coming next.

Design for the Contents column, in light and dark: headings that fold, faint bars showing how long each section is, a line to continue where you were, and a filter that shows matches under their headings.

5Grow together with AI

AI that works beside you, in the open

  • Agents propose, you decideNow

    An agent may add its own notes, always signed and undoable in one click. Changes to your words wait in a review queue as a diff.

  • Bring your own AINow

    Claude Code or any tool that speaks MCP can join as a guest, with the access you grant, and never your private notes unless you say so.

  • Your Guidelines, in a noteNow

    Tell every agent how to work in one plain note they all read before they start.

  • Agents that learn and growLater

    A small team, each with a role, earning trust from your decisions and remembering what worked, through LEAP.

An idea for later: four agents, an owl librarian, a fox researcher, a rabbit gardener and a guest bird for Claude Code, each with a role and a level earned from your decisions, and a job board where they hand work to each other.

An idea for later: your agents, their roles and the work they hand each other.

Every day

A pleasure to write in for hours

Writing that never waits Now

Built so each key shows within a frame, even in long notes. Saving never moves your place, and one Cmd-Z undoes anything Pompom did.

Files and contents beside you Now

Your folders in one column, with drag to move and undo, and the note's outline in the other.

Writing by keyboard Coming

Move by block, jump to any heading or link in two keys, and dim the rest to focus on one paragraph.

Move in from Obsidian or Notion Now

Bring your vault or export. Links are rewritten, private notes stay private, and the originals are left untouched.

English and Chinese Now

Search, links and topics understand both from the start, including notes that switch mid-sentence.

Tasks and reminders Now

Write a task with a date in any note. Pompom gathers them on Today and reminds you on time.

Yours, on your computer

Nothing leaves without you

Plain files

Ordinary markdown in a folder you choose, with history in git. Open them with anything, forever.

On this computer

Pompom runs on your machine and is reached only from it. No account, no cloud copy, no tracking of any kind.

Private stays private

Mark a folder or a tag private, and its words are never sent to any model, notification or outside service.

Pompom the hamster, celebrating.
