Janitor AI is a platform where users create, share, and chat with custom AI characters for roleplay and storytelling. It runs on the JLLM model for free access, with options to connect external LLMs like OpenAI’s GPT. The site hosts over 15 million users, focusing on unfiltered interactions that span casual talks to deep narratives.

Key features include character creation tools that let you define personality, backstory, and initial messages. You upload images and add sample dialogs to shape responses. The memory system tracks details across sessions, ensuring continuity. Trending highlights popular new bots by chat activity, updated every 15 to 30 minutes.

Users like the freedom from content filters, allowing diverse scenarios that competitors like Character.AI restrict. Recent reviews on Reddit from March 2025 praise its role in fantasy adventures, noting novel-like depth. The community sharing adds value, with thousands of prebuilt characters ready to explore.

Drawbacks surface in reliability. Trustpilot entries from August 2025 report frequent glitches and downtime, which disrupts workflows. Bots can generate overly long or off-track replies, requiring prompt tweaks. While free at core, API integrations add costs, comparable to Replika‘s setup but without its advanced scripting.

Technically, it supports multiple backends for varied response styles. JLLM handles basics well, recalling context via embedded notes. Product Hunt feedback from July 2025 highlights the ease of customization, although some users note melodramatic tones in the outputs. The interface remains simple, featuring search and public galleries for easy discovery.

For those testing it, begin with a basic bot to learn prompting. Adjust samples for better alignment. Monitor trending for inspiration. This approach builds familiarity fast, turning potential frustrations into refined experiences.
