The Swiss Army knife of AI roleplay chats

What it does

Agnaistic is a multi-user, multi-bot chat platform for AI roleplay. It connects to a dozen different AI services—Kobold, Claude, OpenAI, OpenRouter, AI Horde, and others—so users aren’t locked into any single provider. It runs as a Node.js app with optional MongoDB for persistence; skip the database and it falls back to browser localStorage in “Guest Only” mode.

The interesting bit

The “agnostic” part is the real pitch. Most character-chat tools marry you to one backend. Agnaistic treats AI services as interchangeable engines and adds multi-tenancy on top—users bring their own API keys, presets, and personas. The optional pipeline layer even does long-term memory and PDF embedding, which suggests ambitions beyond casual chat.

Key highlights

• Supports 10+ AI backends including self-hosted (Kobold, Goose) and commercial APIs
• Group conversations: multiple humans, multiple bots, same thread
• Character generation and image generation via third-party services
• Memory/lore books for persistent worldbuilding
• Subscription system built in (unclear if for SaaS hosting or patron tiers)
• Optional Python pipeline for embeddings and long-term memory

Caveats

• The README is heavy on install steps and light on architecture explanation; some features like “Subscriptions” are mentioned without context
• Pipeline features require a separate Python environment with Poetry—extra complexity for a “quick start”
• 744 stars suggests a niche audience; the “designed with scale in mind” claim isn’t substantiated with numbers

Verdict

Worth a look if you want to self-host character AI without betting on one provider, or if you’re building a small community around shared bots. Skip it if you just want a single-user ChatGPT wrapper—this is overbuilt for that.
