Pros	Best-in-class long-context reasoning Excellent at following style guidelines Projects + Artifacts UX 1M-token context on Sonnet	Backend-agnostic: works with virtually any commercial API and every popular local runner (Kobold, Ooba, Tabby, llama.cpp, OpenAI-compatible) Runs locally so chat logs, character cards, and API keys never leave your machine Deep prompt control — sampler settings, prompt manager ordering, instruct/context templates, author's notes Mature ecosystem of character cards, world info/lorebooks, and community extensions Group chats, chat branching, swipes, and QuickReply/STscript scripting for power workflows Built-in RAG (data bank + vector storage) plus TTS, STT, and image-gen integrations Completely free and open source under AGPL-3.0 with 300+ contributors and rapid release cadence
Cons	No real-time browsing by default Image generation limited Region availability varies	Steep learning curve — the UI is dense and assumes knowledge of samplers, instruct formats, and context templates Requires local installation (Node.js or Docker); no hosted SaaS version officially exists Primarily aimed at roleplay/creative-writing use cases; overkill as a plain assistant chat client You still need to bring (and pay for, if commercial) your own model backend Extension quality varies and some integrations (image-gen, TTS) require separate services running alongside
