How Lifelog Creates Your Daily Doodle

One of Lifelog's most distinctive features is the daily doodle: a small black-ink illustration that appears on your calendar for any day you record an entry. It's not a generic icon or emoji—it's a tiny scene pulled from whatever you actually talked about.

This guide walks through how that works, step by step, without any technical jargon.

The big picture

When you finish a voice note, Lifelog does three things in sequence:

Transcribes your audio into text
Picks one drawable moment from your entry
Generates a minimal ink doodle and places it on your calendar

You see a single loading animation on the calendar until all three are done—then the doodle and transcript appear together.

Step 1: You record a voice note

Everything starts with your voice. You talk about your day—a conversation, a meal, a walk, something funny, something hard. Lifelog saves the audio and queues it for processing.

The doodle can only reflect what you actually said, so the more specific your entry, the more specific (and charming) the drawing tends to be.

Step 2: Lifelog transcribes and titles your entry

AI transcription converts your speech into readable text. Lifelog also suggests a title, emoji, and tags automatically, so your timeline stays scannable even when you have dozens of entries.

This happens first because the doodle step reads your transcript—not your raw audio—to decide what to draw.

Step 3: AI picks one scene from your day

Here's where it gets interesting. An AI reads your transcript and asks a simple question: what's the one moment from this entry that would make the cutest, most memorable little drawing?

It looks for something concrete and drawable:

Two stick figures laughing over pizza while a dog steals a crust under the table
A runner splashing through a puddle with a leashed dog pulling ahead
A steaming bowl of ramen with chopsticks resting on the rim

The AI avoids vague fallbacks—a lone stick figure "thinking" or "journaling" doesn't make the cut. It wants a specific mini-scene from your actual day.

If your entry is emotionally heavy or low on detail, it picks something gentle and evocative instead—still concrete, still drawable.

Step 4: The doodle is drawn

That scene description becomes a prompt for an image model tuned for minimal black-ink illustration—stick figures, simple props, no text or letters inside the drawing. The background is removed so the doodle sits cleanly on your white calendar cell.

The style is consistent across all entries: small, monochrome, sketch-like. Think diary margin doodle, not photorealistic art.

Step 5: It lands on your calendar

The finished PNG uploads and attaches to your entry. On the timeline, that day's cell swaps from a loading waveform to your doodle. Tap the day to replay the audio, read the transcript, and see the doodle larger in the entry header.

Each entry gets one doodle. Re-recording or regenerating (from the entry menu) replaces it with a fresh take on the same transcript.

Why doodles instead of photos?

Photos are great but they require you to take them. Most meaningful moments never get captured on camera. A voice note takes ten seconds; the doodle gives you a visual anchor for that memory without staging a shot.

Over a month, your calendar becomes a grid of tiny illustrations—each one a different day, a different scene. Scrolling back feels like flipping through a visual diary even though you never picked up a pen.

What makes a good doodle?

Entries with clear actions, people, places, or objects tend to produce the most fun drawings. Compare:

Vague: "Had a normal Tuesday."
Specific: "Made pancakes with the kids and syrup ended up on the ceiling."

The second one gives the AI something to work with—and you'll smile when you see it on the calendar three months later.

Try it yourself

Record a short entry about something that happened today—even something small. Wait for the loading animation to finish, then check your calendar cell.
