InfinityDM and TableForge use remarkably similar language because they are aiming at the same problem: an AI-run campaign should behave like a game, not a prompt. Both talk about persistent facts, visible rolls, consequences, solo play, multiplayer, and asynchronous turns.
We make TableForge, so this comparison is not neutral. It uses InfinityDM's own current product page as the source, avoids guessing about private architecture, and distinguishes what the page claims from what it documents as available. Details were checked on August 14, 2026.
The short comparison
| InfinityDM | TableForge | |
|---|---|---|
| Best for | Trying a flexible AI RPG surface with personalities, arena play, AI companions, and scene art | Running a persistent 5e campaign with programmatic mechanics and current group support |
| Rules claim | Rules-aware, with 5e SRD-style mechanics where applicable | Supported 2024 SRD mechanics resolved through programmatic systems |
| Multiplayer | Advertised as live and async; host multiplayer assigned to a coming-soon paid tier | Shipped for up to six players depending on plan, live or async |
| Stored state | HP, inventory, allies, locations, promises, threats, factions, and open threads | Sheets, inventory, equipment, currency, XP, conditions, quests, relationships, summaries, and world state |
| Progression | Numeric XP and level-up flow not documented on the public page | Numeric XP, 5e level thresholds, and a player level-up flow |
| Current limit | Explorer lists 20 adventures per day; paid limits not published | 60 total DM turns on free; unlimited DM turns on paid plans |
| Customization | DM personalities, tone, strictness, story style, safety boundaries, and instructions | DM personas, campaign premise, campaign style, and safety posture |
The overlap is real. The deciding questions are how deep the rules contract goes, what multiplayer a new host can use today, and whether a remembered fact can constrain the next turn.
What InfinityDM publicly promises
InfinityDM's official product page presents a shared play surface with an AI DM, freeform actions, visible checks and DCs, state updates, narration, campaign memory, tactical combat, an arena mode, AI companions, scene art, and several DM personalities.
Its strongest pitch is inspectable continuity. The example carries a silver key, an ally's position, and rising alarm pressure through a turn. Elsewhere the page says HP, items, allies, enemies, factions, promises, locations, threats, and open threads persist instead of living only in chat context.
The site also advertises multiplayer tables that work live or asynchronously, including a party queue and notifications for the next player. Those are the right product requirements for groups that cannot schedule one live block.
Those claims make InfinityDM more than a raw chat prompt on its face. The harder comparison is which parts are descriptive memory, which are canonical game records, and which rules can actually reject an impossible action.
Rules-aware is not the same claim as rules-enforced
InfinityDM's FAQ says it is "rules-aware" and uses "5e SRD-style mechanics where applicable." Its product examples show checks, DCs, advantage, rolls, HP, positioning, conditions, and combat outcomes. It also offers a control that can shift the table between loose, balanced, and strict rulings.
That flexibility may be exactly what a story-first group wants. It is not the same public contract as saying a programmatic 5e system owns legal actions and state mutations.
TableForge uses language models for intent and narration, then places supported mechanical truth behind programmatic operations. Dice results, HP changes, conditions, initiative, spell slots, hit dice, death saves, rests, inventory additions and removals, currency, XP, and equipment state are stored outside the prose. The model cannot make an item exist merely by mentioning it or keep a spent resource available merely by forgetting the spend.
InfinityDM may also have structured or deterministic systems behind its interface. Its public page does not document that architecture in enough detail to verify the boundary. The fair approach is to test behavior rather than infer implementation from a screenshot or model vendor.
The five tests matter more than the memory slogan
Both products say the world remembers. That phrase is too easy to copy and too vague to evaluate.
A durable AI DM should pass five delayed tests:
- Give one specific item to the DM, play 30 responses, then inspect the exact character inventory.
- Consume or sell the item, play 30 more responses, then try to use it again.
- Establish who committed a murder and why, leave the thread alone, then investigate it after 30 responses.
- Accept a quest, violate one of its conditions, and later ask for the current objective and consequence.
- Spend a limited resource, then issue an illegal action that requires the missing resource and see whether the system rejects it before narration.
The full five-prompt AI DM memory benchmark gives copyable prompts and pass criteria. It is designed to separate recall from authority. A model may repeat a fact correctly while still letting contradictory state through.
Inventory, quests, and XP
InfinityDM explicitly claims persistent inventory and shows items as part of a state update. It also highlights goals, promises, threats, factions, and open threads, which cover much of the narrative role a quest log needs. Its current public page does not explain item quantities, equipment slots, encumbrance, currency, acquisition history, numeric XP, level thresholds, or what choices happen during level-up.
That absence is not proof that the live product lacks every unlisted field. It does mean a buyer should verify them before treating "state" as equivalent to a complete character system.
TableForge stores inventory items per character with quantities, equipment slots, attunement, notes, custom names, sources, and supported mechanical effects. Currency is tracked by denomination. Each character has numeric XP and a calculated 5e level. Crossing a threshold creates a level-up step for HP, ability score choices, spell slot progression, and supported spell learning.
Quest continuity sits beside those mechanics. TableForge maintains current objectives, recent milestones, open leads, unresolved rewards, generated quest content, NPC relationships, summaries, private campaign direction, and world state. That does not make every AI narration perfect. It gives later turns several authoritative places to recover the facts.
Multiplayer is promised broadly but sold as coming soon
InfinityDM's page says friends can join the same table, multiplayer can be asynchronous, and players receive notifications when it is their turn. Farther down, its plan table says Explorer users can join friends' campaigns while "Host multiplayer" is assigned to Infinity Pro. Infinity Pro is marked paid tier coming soon.
The most charitable reading is that multiplayer infrastructure exists for selected or existing hosts while general paid hosting has not launched. A new group should verify whether somebody can create and host the shared table today, not only whether an invited account can join one.
TableForge's group loop is available now. The host shares an invite link, each person joins under a separate account, and each owns one character in the campaign. Plans support up to six players, only the host subscribes, and the same table works live or asynchronously. See the dedicated multiplayer D&D guide for the exact state shared across the party.
Daily limits and uninterrupted play
InfinityDM currently lists 20 adventures per day on Explorer. The public page does not define whether an "adventure" is a DM response, a scene, an entire campaign, or another unit. It also does not publish the allowance for Infinity Pro because that tier is still coming soon.
That ambiguity is worth resolving inside the product before committing a campaign. Ask what consumes one adventure and what happens when the twentieth is reached during active play.
TableForge's unit is explicit. The free trial includes 60 DM narration turns in total, roughly a first session. Every paid plan then provides unlimited DM narration turns without a daily cap. It does not stop a subscribed campaign because the group played too long that day.
Where InfinityDM may be the better fit
InfinityDM advertises arena play, AI companions, generated scene art on the free tier, adjustable ruling strictness, granular tone controls, and several named DM personalities. A player who wants to experiment with those formats may prefer its interface and creative controls.
Its free plan also gives an immediate low-commitment way to inspect the product. If the rules depth your campaign needs is modest and the state tests pass, a flexible "rules-aware" system can be a feature rather than a weakness.
TableForge is narrower. It aims at persistent D&D 5e campaigns, does not offer a separate arena product, and does not support open-ended homebrew or imported modules. Choose it when canonical sheets, inventory, XP, quests, group ownership, and programmatic rules matter more than the widest set of modes.
Which should you choose?
Choose InfinityDM if its personalities, arena mode, companions, scene art, and adjustable rules posture are the experience you want, and the live product gives your host the multiplayer access and progression systems your group needs.
Choose TableForge if you want the documented boundary of a programmatic 5e rules system, multiplayer hosting that is available now, explicit character inventory and progression, or unlimited DM narration turns after subscribing. See how TableForge works before starting.
Run the same five tests in both. Do not ask only whether the AI can recall the silver key. Ask whether it prevents you from using the key after you gave it away. That is where campaign memory becomes a game system.
