The Concept

A reader companion app that tracks every stat change, new skill, item drop, and quest as you read your favourite LitRPG series. Think of it as a live character sheet that updates with your reading progress.

01

Read Anywhere

Kindle, Audible, Royal Road, Kobo — QuestLog syncs your reading position via Whispersync page locations, Royal Road chapter tracking, or manual chapter select.

02

Auto-Update

As you pass key chapters, the character sheet updates: new stats, skills, items, and quests appear. Community-curated data packs per book — no author work required.

03

Explore

Inspect skills, compare gear, browse the inventory, follow active quests. It's like pausing a game to check your build — but for your book.

04

No Spoilers

Everything beyond your current reading position is locked. You only see what you've read. Abilities, items, and quests from future chapters stay hidden until you get there.

Live Demo

Pick a book. See the character sheet at a specific chapter. This is what QuestLog would look like while you're reading.

Ch. 1–8

The Accidental Crawler

Level 1 · No Class · Human
A regular guy in heart-patterned boxer shorts, a brown leather jacket, and his ex-girlfriend's pink Crocs. Carrying half a pack of Marlboros and a Zippo. No shoes. No pants. No idea what's happening. The dungeon just ate the world and he's standing in his underwear.
STR 5 DEX 4 CON 5 INT 6 CHA 8
Midjourney / DALL-E Prompt
Dark fantasy character portrait, confused man standing in apocalyptic rubble, wearing only heart-patterned boxer shorts, brown leather jacket open over bare chest, pink Crocs on feet, holding a lit cigarette, bewildered expression, dramatic lighting from above, dungeon entrance glowing behind him, dust particles in the air, a small Persian cat at his ankles looking regal, cinematic composition, dark moody atmosphere, concept art style, 4K --ar 2:3 --v 6

Still in the boxers and jacket, but now battle-scarred and muscular. Fists wrapped in glowing enchanted gauntlets (Fists of the Berserker). Eyes burning with berserk energy. Princess Donut rides on his shoulder wearing a glittering tiara. A clockwork shield drone orbits around them. He's learned to weaponise chaos.
STR 14 DEX 11 CON 17 INT 13 CHA 19
Midjourney / DALL-E Prompt
Dark fantasy character portrait, muscular brawler man in battle-worn heart-patterned boxer shorts and tattered brown leather jacket, glowing golden berserker gauntlets on fists, battle scars on arms and face, confident fierce expression, a regal Persian cat wearing a sparkling jeweled tiara sitting on his shoulder, a small clockwork bronze shield drone floating nearby, standing in a dungeon arena with magical torchlight, purple and gold energy particles, dramatic lighting, concept art, painterly style, 4K --ar 2:3 --v 6

FLOOR 9 · LEGEND
Ch. 80+

The People's Champion

A gladiatorial figure wreathed in explosive energy. The boxer shorts are iconic now — the entire multiverse watches him on the dungeon's reality TV broadcast.

A young Australian man pulled into another world. Average build, dark hair, smart mouth. Wears whatever medieval-ish clothing he can find.

Midjourney / DALL-E Prompt
Fantasy character portrait, young man with dark hair and a wry smirk, wearing simple medieval traveler clothes that don't quite fit, dark purple shadow tendrils faintly visible around his hands, standing in a lush fantasy forest clearing with ancient stone ruins, looking slightly out of place, a small blob of living blood (familiar) hovering near his shoulder, mystical atmosphere, warm golden light filtering through trees, watercolor meets concept art style, 4K --ar 2:3 --v 6

The essences have reshaped him. Leaner, more predatory. Wears a dark cloak that seems to drink in light (Cloak of Night). Shadows cling to him naturally.

Jason has become something more than human. Gold rankers live for centuries and reshape reality. His shadow abilities can blanket entire battlefields in darkness.

GOLD RANK 20/20 ABILITIES DOOM AURA
Midjourney / DALL-E Prompt
Epic dark fantasy character portrait, powerful mage figure wreathed in living shadows and doom energy, flowing dark robes with constellations of dark purple and crimson light embedded in the fabric, multiple shadow arms extending from his back like dark wings, eyes blazing with cosmic void energy, an aura of doom radiating outward causing the ground to crack, modern city skyline visible in background being overtaken by magical energy, his blood familiar formed into an elaborate suit of liquid crimson armour, epic scale, volumetric fog, god-rays piercing through darkness, cinematic, 8K --ar 2:3 --v 6

🏹
F-GRADE · THE TUTORIAL
Ch. 1–50

The Office Worker

F-Grade · Archer · Alchemist
Average-looking guy with short brown hair and brown eyes. Not handsome, not ugly — aggressively normal. Was an office worker who happened to practise archery as a hobby. Then the System arrived and dropped everyone into a tutorial dungeon. Turns out Jake has the Bloodline of the Primal Hunter, and his "hobby" made him the deadliest thing in the tutorial.
AGI 42 PER 68 Bloodline: Primal Hunter
Midjourney / DALL-E Prompt
Fantasy character portrait, average-looking young man with short brown hair crouching in a dense magical forest, holding a crude wooden bow with a nocked arrow, wearing torn modern office clothes (loosened tie, ripped dress shirt), alert predatory expression on an otherwise ordinary face, faint golden glow in his brown eyes hinting at hidden power, a dead monster beast in the background, tutorial dungeon atmosphere with floating blue System text, natural lighting filtering through ancient canopy, survival fantasy aesthetic, concept art, 4K --ar 2:3 --v 6

Midjourney / DALL-E Prompt
Dark fantasy character portrait, lean athletic archer with short brown hair and intense GLOWING YELLOW predator eyes (like a hawk or snake), small scar visible on neck, wearing dark practical hunting leather armour, patches of iridescent toxic green-black snake scales manifesting across his forearms and neck (Scales of the Malefic Viper ability), holding an ornate enchanted bow with an arrow nocked and glowing with arcane cyan energy, a faint ghostly image of an enormous cosmic serpent (the Malefic Viper patron) coiling in the background, alchemical vials on his belt, dark forest clearing, dramatic moonlight, predatory stance, concept art, painterly, 4K --ar 2:3 --v 6

Key Features

What makes QuestLog different from a wiki.

📖 Spoiler-Safe Progression

Every piece of data is tagged to a chapter number. QuestLog only reveals stats, skills, items, and quests up to your current reading position. Future content is locked behind a spoiler gate. Switch books, come back months later — it remembers exactly where you were.

How We'd Build It

Technical approach for the curious.

Data Schema

Each book gets a JSON data pack: chapter-keyed events (stat changes, items, skills, quests). Community contributors use a visual editor. Peer review before publish.

Reading Sync

Kindle: Whispersync page positions (reverse-engineered API exists). Royal Road: Chapter tracking via unofficial API wrappers. Fallback: Manual chapter selector.

App Stack

React Native (iOS + Android) with a lightweight backend. Offline-first — data packs download locally. Real-time sync when connected.

Per-Book Theming

Each series gets a custom colour palette + UI skin. DCC gets dungeon/gameshow vibes. HWFWM gets magical essence colours. DotF gets cultivation jade tones.

Why Now

📈 Genre Growth

LitRPG is the fastest-growing fantasy sub-genre. Dungeon Crawler Carl alone has 500K+ Kindle readers. Royal Road has 10M+ monthly visitors.

🔍 Data Exists

Fandom wikis for top series already track every stat, skill, and item per chapter. The data just needs structuring — not creating from scratch.

🚫 No Competition

Writer tools exist (LitRPG Tracker). Wiki databases exist. Reader companion apps that sync with your progress? Nobody's shipped one.

🤝 Author Incentive

Authors get reader engagement data, an official presence, and a new way to monetize. QuestLog makes their world-building interactive.

Would You Use This?

If you're a LitRPG reader who's ever wanted to check your character's build mid-chapter — this is for you.
