Donjon vs Tabletop Arc: Which D&D Generator Is Best in 2026?

TL;DR — Donjon for fast 5e mechanics, Tabletop Arc for narrative depth and long-running campaign memory. They're complementary, not competing — most experienced DMs run both.

What is Donjon?

Donjon is a long-running collection of free random generators for D&D and other TTRPGs, maintained as a hobby project for over a decade. It includes:

• 5e Random Generator — NPCs, dungeons, encounters, treasure, names.
• Random NPC Generator — Quick stat-block-style NPCs with a name, race, class, and basic traits.
• 5e Dungeon Generator — Procedural dungeon maps with rooms, corridors, traps, and loot.
• Treasure Generator — CR-correct treasure hoards by D&D 5e rules.

Donjon is table-driven and procedural — not AI. Output is fast, consistent, and conformant to 5e rules tables. There's no account, no signup, and no campaign memory.

What is Tabletop Arc?

Tabletop Arc is the AI memory layer for tabletop campaigns. It combines free AI generators with a session-to-canon pipeline:

• Free NPC generator, quest generator, dungeon generator, encounter generator, town generator, magic item generator, tavern generator, name generator, plot arc generator, and battlemap studio.
• Session transcription — Upload audio, get a speaker-separated transcript.
• Evidence-grounded recaps — Every claim links to the transcript segment that proves it.
• Living campaign wiki (Lore Wall) — Every NPC, location, faction, item, and quest is a typed canonical entity with confidence levels and evidence.
• System-agnostic — D&D 5e, Pathfinder 2e, OSR, and homebrew.

Tabletop Arc is AI-driven with structured output. Generators take inputs (theme, setting, tone) and return narrative-rich profiles with motivation, secrets, and plot hooks.

When to use Donjon

Donjon shines when you need a mechanically correct 5e output, fast:

• A CR-balanced encounter on the spot.
• A treasure hoard for a defeated dragon.
• A random dungeon map for a one-shot.
• A quick guard or merchant NPC who only needs a name and basic stats.

Donjon is also a great teaching tool — its outputs follow the 5e DMG closely, so you can use them as reference material for understanding the mechanics.

When to use Tabletop Arc

Tabletop Arc is purpose-built for narrative depth and long-running campaigns:

• An NPC with a personality, motivation, and secret you can roleplay immediately.
• A town with culture, factions, and plot hooks ready to seed adventures.
• A campaign wiki that grows automatically from your sessions.
• Recaps that don't hallucinate because every claim is backed by transcript evidence.
• A living public arc page you can share with your players or readers.

If your campaign will run more than 10 sessions, you need a memory layer — and that's what Tabletop Arc is.

The combined workflow

The strongest 2026 DM workflow uses both:

1. Donjon for quick mechanical needs at the table — stat blocks, treasure, CR-balanced encounters.
2. Tabletop Arc for prep narrative content (NPCs, quests, towns), recording sessions, and maintaining the campaign canon.

Tabletop Arc's NPC generator gives you a character with motivation, secret, and quirk in 3 seconds. Donjon gives you a stat block in 1 second. Together you have a full NPC, ready to play.

Migrating from Donjon to Tabletop Arc

If you've been using Donjon and want a campaign memory layer:

1. Keep Donjon bookmarked for 5e mechanics. Don't replace it; complement it.
2. Start a campaign in Tabletop Arc and add your existing NPCs, locations, and factions as canonical entities.
3. Begin recording sessions (or just upload one to try) and let analysis populate your Lore Wall.
4. After 2–3 sessions, the difference is obvious: your campaign canon is structured, searchable, and growing without manual upkeep.

What's the bottom line?

Donjon and Tabletop Arc are not competitors — they're complementary tools. Donjon is the best free 5e mechanical generator on the open web; Tabletop Arc is the AI memory layer for the rest of your campaign. Use Donjon for fast 5e mechanics, use Tabletop Arc for narrative depth and continuity, and let the two cover the full surface area of D&D prep in 2026.
