Personal Knowledge Management

Personal knowledge management for real life.

Personal knowledge management (PKM) means keeping what you learn, decide and promise somewhere you can find it again. Keplica makes it effortless: talk or type, and it remembers the people, dates and promises for you.

Start your memory

Beyond traditional PKM tools

Note apps store what you write. Keplica understands it.

Capture in seconds, not minutes

Most PKM tools ask you to pick a folder, a template and tags before you write a word. With Keplica you talk or type one line. The structure is built for you afterwards.

It pulls out what matters

Names, promises, due dates, decisions, risks and predictions are picked out of your words automatically, so a rambling voice note becomes a tidy record you can act on.

Ask, don't dig

Ask “When is my car insurance due?” or “What did I promise Priya?” and get a direct answer with the original note linked, instead of scrolling through folders.

Learn from your own calls

Note what you expect to happen, then mark later whether you were right. Over months you see where your judgement is strong and where it slips.

Connected without manual linking

Mention someone in five notes and they get their own page with everything you said about them. Projects collect their own timeline the same way.

Promises land where you will see them

Dated to-dos appear in your action list, a calendar feed for Google, Apple or Outlook, and an optional evening prompt while the app is open.

How Keplica works as a PKM

From a quick thought to a useful answer in five steps.

1

Capture

Record up to five minutes of voice or type a quick note. Attach a photo, PDF or link with one line about why it matters.

2

Extract

Speech is transcribed, then people, projects, promises, dates, decisions, risks and predictions are pulled out of your words.

3

Connect

Every person and project gets a page. Mentions across all your notes link together automatically.

4

Ask

Ask in plain language. Answers cite the exact note they came from, so you can check the original.

5

Follow through

Tick off promises, correct anything the AI got wrong, and mark how your predictions turned out.

Who it is for

Anyone who has ever said “I forgot” is a PKM user.

Busy parents and families

School events, medicine refills, bills, birthdays and what the plumber quoted. Say it once in the car and find it again when someone asks.

Students

Lecture takeaways, assignment deadlines and ideas for essays. Ask “what did the professor say about the exam?” and get the note back.

Managers, founders and freelancers

Meeting decisions, client promises and the reasoning behind big calls. See why you chose something six months later.

Caregivers and health tracking

What the doctor said, which tablets changed, and the next appointment. Keep a clear, dated record without a notebook.

Home, money and admin

Insurance renewals, warranty details, repair plans and rent notices. Attach the PDF or photo with one line, and the date becomes a to-do.

Personal growth

Reflections, promises to yourself and predictions about work, health or relationships, scored honestly over time.

Frequently asked questions

Direct answers about PKM and how Keplica fits in.

What is personal knowledge management?

Personal knowledge management (PKM) is the habit of capturing what you learn, decide and promise, then keeping it findable later. A good PKM system turns scattered notes, conversations and files into something you can search, ask and act on.

Is personal knowledge management only for professionals?

No. Anyone who forgets things benefits. Parents track school dates and medicine, students track deadlines, and caregivers track doctor advice. PKM simply means keeping what matters to you somewhere you can find it again.

What is the easiest way to start personal knowledge management?

Start with capture, not organization. Each evening, record a 30-second voice note of anything you promised, decided or want to remember. Keplica sorts it for you, so the habit takes seconds instead of a weekend setup.

What is the best PKM app for people who hate organizing?

Pick a tool that organizes for you. Keplica lets you speak or type freely, then pulls out people, promises, dates and decisions automatically. There are no folders, tags or templates to maintain.

How is Keplica different from Notion or Obsidian?

Notion and Obsidian are powerful but expect you to build and maintain the structure yourself. Keplica starts from a quick voice or typed note and builds the structure automatically, then answers questions with the original note cited.

How is Keplica different from Apple Notes or voice memos?

Apple Notes and voice memo apps store what you capture but do not understand it. Keplica transcribes your voice, finds the promises and dates inside, adds them to your action list and calendar feed, and answers questions later.

Can I search my voice notes by asking a question?

Yes. Every Keplica voice note is transcribed and indexed by meaning. Ask something like “What did the dentist say about my next visit?” and you get a direct answer with a link to the original recording and transcript.

How do I stop forgetting promises I make to people?

Capture the promise the moment you make it, and have it land somewhere you check daily. In Keplica a spoken promise with a date becomes a dated to-do in your action list and in your Google, Apple or Outlook calendar.

Does Keplica read my photos, PDFs and links?

Not today. Photos, PDFs and links are stored as attachments beside the note. You add one spoken or typed line about why they matter, and Keplica organizes that line while keeping the file one tap away.

How long can a Keplica voice note be?

Each recording can be up to five minutes. That covers most meetings recaps, doctor visits and evening reflections. For longer events, capture the key takeaways in a short note right afterwards.

Is there a free plan?

Yes. The free plan includes 20 captures a month, with voice recordings kept for 90 days. The text, people, promises and insights from every note stay permanently, even after the audio is archived.

Can I use Keplica for work and family at the same time?

Yes. Keplica is built around your memories, not separate workspaces. One note can mention a work deadline and a family errand, and each person or project still gets its own page.

Does Keplica use my data to train AI models?

No. Your notes, recordings and extractions are private to your account and are not used to train AI models. AI processing only runs to organize your own notes and answer your own questions.

Can I export my data if I leave?

Yes. Settings lets you download everything as JSON or Markdown at any time, and you can delete your account and all its data yourself.

What is a second brain?

A second brain is an outside system that remembers for you, so your head is free to think. Keplica is a second brain you can talk to: it stores your notes and answers questions about them with sources.

What makes a PKM system actually useful?

Three things: capture must take seconds, retrieval must be easy, and important items must come back when they matter. If any of these fail, notes pile up unused. Keplica focuses on all three.

Core capabilities that power the memory graph

Voice-first capture

Record a thought and get a searchable transcript plus structured extractions.
