DreamGen vs Janitor AI vs SillyTavern Comparison

AI role-play chatbots have gone mainstream. Millions of writers, gamers and late-night storytellers now log in looking for partners who deliver immersive, uninterrupted scenes.

We put the three fan favorites (DreamGen, Janitor AI and SillyTavern) through seven stress tests covering memory, content freedom, price, safety and narrative punch. Read on to see where each bot excels, where it stumbles and which one matches the way you like to role-play.

How we tested

To move past marketing claims, we put each platform through the same seven-part obstacle course.

First, we built a master prompt pack filled with fantasy duels, steamy romance beats, detective banter, and slice-of-life chat. Each scene tucked in trackable clues such as a dragon's real name or a villain's hidden motive.

We ran that pack three times on DreamGen, Janitor AI, and SillyTavern, changing only character names to rule out lucky runs. The process produced 21 conversations per platform and a tidy stack of transcripts.

Every transcript went through a 10-point scoring sheet covering memory, creative freedom, ease of use, price, privacy, world depth, and extensibility. Memory and content freedom counted double because users rank them highest.

Finally, we averaged the scores, inspected outliers, and debated until the math and our instincts matched. The result is a fair verdict you can trust.

Numbers tell only part of the story, but they set the stage for the seven tests ahead.

Memory retention (Test 1)

Long scenes crumble when a bot forgets who did what, so we checked whether each platform still remembered our dragon's real name after 100 messages.

DreamGen performed best. Its Pro-tier context window stretches to 30,000 tokens with GLM 4.7, and the scenario codex pins key details -- character backgrounds, plot threads, setting rules -- so the AI references them consistently. We passed 12,000 tokens before noticing any drift, earning a steady 9/10.

Janitor AI lost track sooner. The free Janitor-LLM began blurring history near 1,000 tokens. By message 20 our dragon became "that creature," and contradictions followed. Upgrading to GPT-4 helped, but your OpenAI bill grows. Overall score: 4/10.

SillyTavern sits in the middle. Retention matches whatever model you connect. A local 13 B model lost the plot halfway, while GPT-3.5 16 k stayed sharp. Enable Lorebook or vector memory and SillyTavern can rival DreamGen, though setup adds work. We averaged the highs and lows and landed on 7/10.

Takeaway: For effortless long stories, choose DreamGen. Tinkerers can match it with SillyTavern, and Janitor AI suits quick, casual chats where memory gaps don't hurt the fun.

Creative freedom (Test 2)

Content filters can break immersion, so we steered each bot through romance, sword fights, and gothic horror to see who flinched.

DreamGen never interrupted the scene. From tense villain monologues to steamy romance arcs, every narrative beat landed without a sudden refusal or awkward fade-to-black. Independent reviewers reached a similar conclusion in a 2025 industry roundup, We Tested the 10 Best AI Roleplay No Filter Tools. Score: 10/10.

Janitor AI was mood-dependent. With the free Janitor-LLM, scenes flowed though the prose sometimes felt clumsy. Switching to GPT-3.5 or GPT-4 raises writing quality, yet OpenAI safeguards occasionally fade scenes to black. Freedom averaged 7/10, and users trade either quality or consistency to reach that score.

SillyTavern matches DreamGen in raw freedom because it imposes no policy of its own. Connect a community model and every bold trope lands on the page. Use a corporate API and you inherit that provider's brakes. We logged 9/10.

Bottom line: For uninterrupted creative output, choose DreamGen or a locally run SillyTavern model. Janitor AI can play along, but you will juggle model choices and occasional refusals.

Ease of setup and everyday use (Test 3)

Getting started should feel like opening a book, not configuring a server.

DreamGen delivers that instant start. Sign up, pick a scenario and you are writing within sixty seconds. The only wrinkle is its credit meter; learn the token system and sessions stay smooth. Score: 8/10.

Janitor AI is similarly welcoming on day one. Browse the community library, tap chat and the fun begins. Complexity rises when you chase higher-end models, juggling API keys and watching for server slowdowns. Those bumps drop Janitor to 7/10.

SillyTavern asks for more effort. Download or fire up a Colab, tweak configs until ports open and models respond. Once running, the lean interface gives power users full control, but newcomers may find the install steps too steep. Score: 5/10.

Takeaway: DreamGen wins for plug-and-play simplicity, Janitor AI follows closely, and SillyTavern rewards technical users who enjoy hands-on setup.

Pricing and value (Test 4)

Money matters, especially when a weekend binge can burn through a novel's worth of tokens.

DreamGen uses a freemium model. The free tier gives you about 2,000 role-play messages per month using Lucid Base, with daily credits that refill after the monthly pool runs out. All features and models are accessible on the free tier. Paid plans expand context windows and provide unlimited access to first-party models. Score: 8/10.

Janitor AI wins the sticker-price headline. Chat all day without paying by using its Janitor-LLM, or plug in GPT-3.5 and pay OpenAI directly. The site mentions future premium tiers, yet today you can role-play for zero dollars if you accept modest quality. Value score: 9/10.

SillyTavern is as cheap or as costly as you make it. The software itself is free. Run a local 13 B model on a home GPU and your only bill is electricity. Prefer GPT-4? You pay the OpenAI meter. That choose-your-own-budget approach also earns 9/10.

Takeaway: For true zero cost, Janitor AI and SillyTavern share first place. DreamGen charges a fair convenience premium that many writers are happy to pay.

Safety and privacy (Test 5)

Creative freedom matters, but no one wants private chats leaking online.

DreamGen stores sessions on its own cloud servers. Traffic is encrypted and the team states that staff never open private chats unless you grant permission via a support ticket. There is no self-host option or parental gate. Good for adults who trust the platform, less ideal for families. Score: 7/10.

Janitor AI is also cloud based, and every connected API receives your text. Policies feel informal, outages occur, and age checks rely on a simple checkbox. That uncertainty drops the score to 6/10.

SillyTavern takes the opposite path. Run it locally and nothing leaves your machine, so privacy climbs to maximum. The trade-off is zero built-in moderation; safety rests on you. We gave it 8/10.

Verdict: DreamGen and Janitor AI keep data in their clouds and ask for trust, while SillyTavern keeps data at home but shifts all responsibility to the user.

Multi-character and world depth (Test 6)

Role-play flourishes with ensemble casts and layered settings, and here DreamGen and SillyTavern lead in different ways.

DreamGen builds scenario tools into the interface. The scenario codex lets you define plot, setting, writing style, and multiple characters -- each with backgrounds, goals, and relationships. In our mystery test the detective, witness, and nervous suspect kept distinct voices throughout the arc. You can also edit, delete, or add any message in the thread, including NPC dialogue the AI generated. Story Mode shifts to a text editor for writers who prefer narrative prose over chat. Score: 9/10.

Janitor AI leans on one-to-one chemistry. Its character editor is deep, yet the chat window hosts a single persona at a time. You can fake a group with a dungeon-master prompt, but juggling roles yourself grows tedious. World-depth score: 6/10.

SillyTavern is built for full casts. Group Chat loads several character cards and the AI bounces between them. Add a Lorebook and the app auto-injects setting notes whenever a keyword appears, keeping lore consistent even in lively tavern scenes. Once configured, SillyTavern handled five characters arguing over dragon loot with no drops in coherence. Score: 10/10.

Takeaway: DreamGen delivers rich, turnkey storytelling, SillyTavern rewards builders who crave cinematic control and Janitor AI shines in focused one-on-one chats.

Extensibility and integrations (Test 7)

Some role-play sessions spill beyond a single browser tab. You might feed lines into Discord, drive a VR avatar or narrate a tabletop stream.

DreamGen offers partial access. Paying subscribers get API access, and its models can power custom apps or bots. You cannot modify the DreamGen interface; it remains a curated workspace. Score: 8/10.

Janitor AI takes the opposite path. The site accepts many external models, yet it gives outsiders no API connection. You can choose engines such as GPT-4, Claude or DeepSeek, but once text lands inside, the platform is a silo. Score: 6/10.

SillyTavern swings the doors wide. The code lives on GitHub, extensions are plain JavaScript and connectors exist for major APIs plus local back ends. Need ElevenLabs voice, Stable Diffusion art or a custom dice roller? Add a plug-in and restart. That builder-friendly spirit earns SillyTavern a perfect 10/10.

Takeaway: Pick DreamGen when you need a polished model you can call from other tools. Use Janitor AI for quick model swapping inside one site. Choose SillyTavern when you plan to script, fork or bolt AI brains into larger creative projects.

Scoreboard and key insights

After seven trials and 21 transcripts per platform, the numbers tell a clear story:

Test	DreamGen	Janitor AI	SillyTavern
Memory retention	9	4	7
Creative freedom	10	7	9
Ease of setup	8	7	5
Pricing & value	8	9	9
Safety & privacy	7	6	8
Multi-character depth	9	6	10
Extensibility	8	6	10
Weighted total	187 / 210	149 / 210	176 / 210

Three patterns stand out:

1. Context windows matter. Large buffers and memory tools prevent plot amnesia.
2. Filters live in the model, not the interface. Pick a lenient engine and both DreamGen and SillyTavern let the story flow.
3. Convenience carries a cost. DreamGen charges dollars, SillyTavern charges learning time and Janitor AI charges in occasional hiccups.
