CrushOn AI and PolyBuzz both promote character libraries and user-created conversations. Their own catalog numbers are marketing claims and can change; the practical question is whether a reader can find three promising profiles for a specific story. A huge feed is useful only if search, tags and profile descriptions make a suitable character visible.
Test discovery before chat
Pick a narrow fictional adult premise such as a reluctant space-ship navigator, then search it on each site. Count how many results have a clear motivation, setting and opening conflict rather than a portrait with generic praise. Open three results and read their first messages. Do they invite the user to make a choice, or simply announce a personality? This quick audit separates library breadth from usable writing material.
PolyBuzz’s public site emphasizes discovery, character creation and multiple interaction formats. CrushOn’s roleplay material emphasizes genres and longer arcs. Those are useful starting points but not independent proof of conversation quality. Try one matched premise on each platform for at least fifteen turns, correcting a navigation detail in the middle. Record whether the character retains the correction and keeps a consistent voice.
Check the edges of the product
Public libraries need visible reporting and content rules. Review how each service handles character publication, private chats, blocking and deletion. PolyBuzz says public NSFW display is prohibited; check its current policy and whether that matches your intended use. CrushOn has different adult-oriented positioning and still needs clear age and moderation boundaries. Never assume a “private” label means no data is retained; read the provider’s policy.
If you create characters, compare how much profile text can be edited and whether changes affect existing conversations. If you only browse, that control may not matter. Compare plan allowances from live account screens rather than repeating an old free-message figure.
Decision
PolyBuzz may fit a reader who wants broad public character exploration and a variety of formats. CrushOn may be more direct for genre-led adult roleplay. Neither wins by catalog size alone. Choose the service where a well-specified character remains interesting after the first exchange and the account controls fit your privacy expectations.
