Six generators. Millions of combinations.
Entities, artefacts, tomes, cults, locations, and plot hooks — procedurally conjured for writers and GMs. No AI. No internet.
Eldritch Generator conjures procedural cosmic horror content for writers, Game Masters, and connoisseurs of the weird.
Six generators. Millions of combinations. No two results alike.
No AI. No internet. Pure combinatorics running locally on your device.
— ENTITIES —
Summon beings from beyond the threshold of comprehension. Each entity is assembled from phoneme tables (unpronounceable names), weighted attribute pools (domains, forms, weaknesses), and clause templates (worship practices, atmospheric flavour text). A unique occult sigil is procedurally generated for every entity.
— ARTEFACTS —
Generate cursed objects with plausible provenance. Materials, supernatural properties, and the price they exact from their holders — every artefact has a history assembled from real-world locations and dates, and a current whereabouts that begs investigation.
— TOMES —
Create forbidden texts in impossible languages. Formats range from copper scrolls to wax cylinder recordings. Contents include things no book should contain. Reader consequences are progressive and specific. Notable passages are included for immediate use at the table.
— CULTS —
Build secret organisations with hierarchies, goals, methods, and recognition signals. Founded during real historical events. Operating through plausible front organisations. Members drawn from specific demographics. Current status ranges from "active and growing" to "technically victorious — their goal was achieved in 2003, but no one noticed."
— LOCATIONS —
Produce cursed places where reality runs thin. Real geographic regions. Measurable anomalies. Documented-sounding history. Local warnings delivered in the clipped tones of someone who has seen enough. Every location feels like somewhere you could drive to and probably shouldn't.
— PLOT HOOKS —
Generate complete scenario seeds with setups, complications, stakes, clues, and twists. A tag-based coherence system ensures thematic consistency — a mystery about a forbidden text gets complications about translations and experts, not about coastal geography. Every hook includes an atmospheric mood line ready for the opening of a session.
— FEATURES —
Tap any field to re-roll it independently while keeping the rest. Found the perfect entity name but want a different domain? One tap.
Save favourites with personal notes. A dedicated Favourites tab shows saved items across all six categories. Export everything as formatted text.
Browse your last three generations per tab without losing them. History dots at the bottom of each screen let you flick back to something you summoned two taps ago.
Adjust generation with three controls: name complexity (simple to baroque), description length (terse to elaborate), and tone (Cosmic, Gothic, Clinical, or Mythic). Cosmic gives you Lovecraft. Gothic gives you Poe. Clinical gives you the SCP Foundation. Mythic gives you Clark Ashton Smith.
Share results via Messages, email, social media, or any app.
Copy to clipboard for session notes. The formatted output is plain text — paste it anywhere.
— AESTHETIC —
Dark parchment on void. Aged manuscript cards with procedural rough edges, tea-stain watermarks, and candlelight vignette. Ink-bleed text animations. Slow-drifting dust motes in the darkness. A vertical sidebar for navigation. No bright colours. No cheerful UI. The app looks like something you found in a locked drawer and probably shouldn't have opened.
— PRIVACY —
No network connection. No data collection. No tracking. No analytics. No AI. Everything runs locally. Nothing leaves your device. The only thing watching you is whatever you just summoned.
Built for the table. Built for the page. Built for 2am when your players have gone off-script and you need a cult in thirty seconds.
