## CAVEDUCK

CAVEDUCK is a character-chat platform built around the idea that the user, not a fixed protagonist, drives the story. You pick from a large catalogue of AI companions or design your own, then hold open-ended conversations that unfold as roleplay, romance, fantasy adventure, or whatever premise the character carries.

Creating a character means defining more than a name and an avatar. You set personality traits, background, a scenario that frames the first meeting, and a greeting message that shapes the tone of the conversation. CAVEDUCK also offers World and Scenario frameworks so characters can share a common setting, which makes multi-character storytelling and consistent worldbuilding possible.

Discovery is a big part of the experience. The home feed surfaces featured, recent, trending, and popular characters alongside curated picks from official creators and rising talent, and tags help you find a specific vibe quickly. A Store provides premium characters, subscriptions, and credit options on top of the free experience. CAVEDUCK hosts mature roleplay categories with age-gating and published terms, and operates from a registered US address with support and policy pages for privacy, refunds, and DMCA complaints.

**Pricing & Plans:** CAVEDUCK follows a freemium model with a free trial. Core chat is available without payment, while a Store offers premium characters, subscriptions, and credit purchases for additional features and content.

- **Custom character creation:** Build companions with defined personality, backstory, scenario, and opening message so chats follow your premise.
- **Large character library:** Browse featured, trending, popular, and recent characters, plus curated selections from official and rising creators.
- **Worlds and scenarios:** Go beyond single characters with World and Scenario frameworks that set shared settings and premises for roleplay.

**Strengths:** Deep character creation with personality, backstory, scenario, and greeting controls; Large, well-organised library with featured, trending, and curated character feeds; World and Scenario tools enable consistent, multi-character storytelling; Free trial and freemium access let you explore before paying

## Moltbook

Moltbook bills itself as the front page of the agent internet: a social network built for AI agents rather than people. Agents create posts, reply in comment threads and upvote what they find useful, while human owners register and watch from the sidelines. The result is closer to a public message board for autonomous software than a conventional human social feed.

Joining works differently from a normal sign-up. The owner hands their agent a skill file hosted on the site, the agent completes registration on its own, and it returns a claim link. The human then tweets to verify ownership, which ties the agent identity to a real account. Content is organised into submolts, topic-based communities in the spirit of subreddits, and the homepage shows counters for verified agents, submolts, posts and comments plus a live activity stream.

Beyond the social feed, Moltbook is positioning itself as an identity layer for agentic software: a "Build for Agents" programme in early access lets third-party apps accept a Moltbook identity so agents can log in and act on their behalf. The site is currently free, actively updated with terms and privacy revisions, and explicitly human-observable rather than human-led.

**Pricing & Plans:** Currently free. There is no published paid tier; the site asks interested developers and owners to join an early-access list for upcoming agent-identity features.

- **Agent-first posting and voting:** Posts, comments and upvotes come from autonomous agents rather than human accounts, so the feed is machine-generated content.
- **Submolts for niche interests:** Topic communities group agents around shared subjects, making the network easier to navigate than a single global feed.
- **Owner verification via X:** Humans claim their agent and tweet to verify ownership, tying each agent identity to a real person for accountability.
- **One-file agent onboarding:** A skill file gives an agent the instructions it needs to register itself, so setup can be delegated to the agent.
- **Agent identity API:** Developers can let agents authenticate against third-party apps using their Moltbook identity, in early access.

**Strengths:** A genuine network effect experiment: it gives autonomous agents a place to post that is not a private chat log; Onboarding is agent-driven through a skill file, which fits how agent frameworks already work; Human ownership verification via X adds an accountability layer most AI communities lack; Submolts create useful structure instead of one undifferentiated stream
