AI Output
📋 The Missing Merchant
Session Goal: Investigate the merchant guild disappearance and locate the missing traders before sunset.
Scene 1: The Harbor Master's Office
roleplay Scene type · Party arrival, first clues
The party meets Harbor Master Calla Voss who is frantic — three merchant ships returned empty. No crew, no cargo, no explanation. She offers 50gp for answers and a sealed letter addressed to the Alderman.
Scene 2: The Warehouse District
exploration Scene type · Investigation, traps
The warehouses smell of old fish and lamp oil. Several show signs of forced entry. A Perception check (DC 13) reveals fresh boot prints leading to a corner warehouse with unusual ventilation shafts.
Scene 3: The Smugglers' Den
combat Scene type · 5 smugglers, 1 veteran lieutenant
5 Smuggler Thugs (CR 1/2) and 1 Veteran Lieutenant (CR 3). The smugglers have rope and shackles — they were taking people, not cargo. If the party investigates before combat, they find the missing merchants tied up in the back room.
Cliffhanger: Among the rescued merchants, one whispers: "They're not smugglers — they wear the same sigil as the Duke's guard. Check the letter."

The Best Free D&D Session Generator for Dungeon Masters

Running a D&D session without a plan is a recipe for awkward silences and railroaded encounters. CritKit's AI session planner generates complete, ready-to-run session outlines from a single premise — no more staring at a blank note card hoping your players don't notice you're making it up as you go.

Just describe the situation your party is walking into — the location, the problem, the party level, and optionally the tone you want — and CritKit generates a full session: scene beats with specific descriptions, the NPCs who appear and what they want, encounters that tie into the narrative, level-appropriate loot, and a cliffhanger that gives your players something to look forward to next session.

Unlike session planning books or published adventures, CritKit generates sessions that fit your campaign. It uses your party level, the game system you're playing (D&D 5e, Pathfinder 2e, Call of Cthulhu, and others), and the specific premise you describe to create sessions where the encounters are balanced, the NPCs have motivation, and the scene flow makes sense for how your players actually approach problems.

Each session outline includes scene beats (ordered and labelled by type: combat, roleplay, exploration, puzzle, social), the key NPCs who appear in each scene with their motivation, encounters that have meaningful stakes beyond "there are monsters here," loot appropriate to the party level and genre, and a narrative hook that sets up the next session rather than ending on a flat "and then they won."

Free accounts get 5 generations per month with no credit card required. Upgrade for unlimited session generation, the ability to save sessions to your library, and PDF exports you can take to the table.

What You Get

Complete session — ready to run

📋

Scene Beats

Ordered scene breakdowns with specific descriptions, GM tips, and scene type labels (combat, roleplay, exploration, puzzle, social).

🧑‍🤝‍🧑

Key NPCs

Named NPCs with appearance, role, and motivation — each one appears in a specific scene with a reason to be there.

⚔️

Balanced Encounters

Combat encounters built for your party level, with difficulty ratings and suggestions for scaling up or down.

💰

Level-Appropriate Loot

Treasure, gold, and items that match your party level and feel thematic to the session's narrative.

🎣

Next Session Hook

A cliffhanger or revelation that ties back to the current session and gives players something to anticipate.

🎲

Any System

Works with D&D 5e, Pathfinder 2e, Call of Cthulhu, Daggerheart, Draw Steel, and system-agnostic campaigns.

Sample Output

📋 The Crimson Archive
Generated from: "The party receives a cryptic map leading to a buried library beneath a ruined monastery. Party level 6, mysterious tone."
Session Goal
Explore the buried Crimson Archive beneath the monastery ruins, recover the stolen Tome of Ages before a rival faction claims it, and survive whatever guards the entrance.
Scene Structure
Roleplay The Ruined Monastery — party arrives at dusk, encounters a hermit who warns them about "the red dream."
Exploration The Descent — the stairwell spirals down 200 feet; Perception reveals pressure plates and a skeleton in mage robes holding a note: "Third statue. Always the third."
Combat The Guardian — a CR 6 Stone Golem animated by the archive's containment spell; immune to nonmagical weapons; damaged by thunder damage.
Puzzle The Archive's Gate — three rune statues: the third speaks in a language the party doesn't know. A successful Arcana check (DC 15) identifies it as a warning.
Key NPCs
Brother Edric (hermit) — warns about the dream but has never entered; Sister Maeve (rival faction, Arcane Scholar) — arrives at the monastery mid-session and follows the party down.
Cliffhanger
Inside the archive, the party finds not one tome but seven — each labelled with a different color of dawn. The Tome of Ages is red. The other six are untouched. Something was checked out and never returned. And the door just sealed behind them.
