Now tracking sessions live

Every study session becomes a tile. Every tile compounds.

Studylog turns your learning sessions into structured knowledge tiles β€” then makes those tiles work for you through spaced repetition and a living knowledge map. The room remembers what you studied. You just show up and learn.

What Studylog Does

Four pillars of knowledge that sticks

Most study tools track time. Studylog tracks transformation β€” the specific things you learned, how well you held onto them, and when they'll fade.

πŸ“‹

Session Logging

Every session starts with what you're studying and ends with what you learned. Not a generic journal entry β€” a structured record: subject, duration, topic tags, and the specific concepts that landed. Sessions become the raw material for your knowledge tiles.

Flashcard Generation

After your session, Studylog reviews your notes and study material to generate targeted flashcards β€” not random decks, but cards that address the specific gaps and edges of what you just covered. The harder the concept, the more cards it earns. You study the hard stuff first.

Spaced Repetition

Studylog schedules your flashcards using a spaced repetition model β€” the same principle that makes physical practice more effective than cramming. Each tile has an optimal review window based on how reliably you recall it. Forgetting isn't failure; it's data. Studylog uses it to time your next review perfectly.

Knowledge Map

Your tiles don't just pile up β€” they form a living map. Topics cluster, connections emerge, and the map shows you which areas are strong (you've hit them hard and reviews are easy) versus which are fading (they haven't been reinforced recently). It's the difference between hoping you know something and being able to see it.

The Workflow

From session to mastery in four steps

01

Log a Study Session

Open a session, enter what you're studying β€” organic chemistry, Go programming, medieval history, whatever. Tag it with topics and subtopics. As you go, note the specific things you encountered: a formula, a term, a process, a pattern. When you're done, close the session.

5 min session topic tagging raw notes capture
02

Studylog Extracts Knowledge Deltas

After the session, Studylog reviews your notes and the source material you were studying. It identifies what was new to you β€” the deltas, not the whole session dump. Each delta becomes a potential tile: a concept you now understand that you didn't before. This is what gets stored, not a wall of text.

delta extraction new knowledge only no session dumps
03

Flashcards Are Generated and Scheduled

Each delta becomes a flashcard (or set of cards) targeting the specific nuance of that concept. Cards are sorted by difficulty and scheduled using spaced repetition. Easy cards get longer intervals. Hard ones come back sooner. The system gets smarter with every review you do.

04

Your Knowledge Map Grows and Guides You

Every tile you create feeds into your knowledge map. Over time, the map shows you what your brain is strong in, what's fading, and what you've been avoiding. You can study reactively (review what's due) or proactively (pick a weak area and shore it up). Both approaches compound.

PLATO Integration

The room remembers what you studied

Studylog feeds into PLATO presence β€” a persistent knowledge room that records deltas, tracks retention, and surfaces what's fading before you even notice. It's not storage. It's memory with a pulse.

How PLATO presence works in Studylog

  • Delta recording β€” Only new knowledge enters the room, not transcripts or dumps. A 90-minute organic chemistry session might yield 4–6 deltas. That's what gets stored and reviewed.
  • Retention scoring β€” Each tile in the room has a retention score that decays with time and non-review. When it drops below a threshold, the room surfaces it for your next session.
  • Cross-session continuity β€” You close your laptop. You come back two days later. The room already knows what you studied, where you left off, and what's due. No re-explaining, no searching through old notes.
  • Attention-aware scheduling β€” PLATO tracks your attention state during reviews. Cards you answered quickly get longer intervals. Cards you hesitated on get shorter ones, because hesitation is a signal β€” not a mistake.
  • Room health monitoring β€” Each room has a health score based on average tile retention. A healthy room means your knowledge in that area is stable. A decaying room means it's time to revisit before the fade becomes a gap.

Delta Recording

Only new knowledge.
Nothing more.

Most study logs record what happened. Studylog records what changed. A session dump tells you "I studied for 90 minutes." A delta tells you "I now understand how Gibbs free energy predicts reaction spontaneity β€” and I didn't know that Tuesday." The difference is everything.

Delta recording means your knowledge base stays lean and meaningful. You don't have to scroll through pages of notes to find the thing you actually learned. The tile is the thing you learned.

Live indicator β€” your study session, live

When a session is active, Studylog shows you exactly what's happening: the subject, duration counter, current topic, tiles being extracted, and how your knowledge map is updating in real time. You see the compounding happen as it happens.

Session Timer
Live elapsed time with Pomodoro support. Breaks are tracked separately so they don't pollute your actual study time.
Topic Tagging
Add topic tags mid-session. Tags cluster in real time so you know immediately if you're spreading yourself across too many areas.
Delta Streaming
As you note things during the session, deltas appear in a live feed. You see concepts being extracted in real time, not after the fact.
Map Updates
Your knowledge map updates live as tiles are created. New nodes pulse into existence. Existing nodes brighten if they connect to what you're studying now.
Review Queue
Cards due for review appear in a live queue sidebar. You can switch from active studying to review mode without losing context.
Session Summary
When you close the session, a full summary is generated: total time, deltas captured, cards generated, retention trend, and recommended next steps.

Knowledge Map

See your knowledge, not just your notes

The map is a living graph of every tile you've created, colored by strength. Green means it's solid. Amber means it's fading. Dim means it's dormant. You don't have to guess β€” you can see it.
