Psyche

Psyche is an independent software publisher that emerged from the open-source community around the GitHub handle Chevey339, focusing on lightweight, cross-platform communication tools built with modern frameworks. The company’s only public release to date is Kelivo, a Flutter-based chat client engineered to interface with large-language-model endpoints while retaining a minimal native footprint on mobile operating systems. By leveraging Google’s UI toolkit, the application compiles into performant ARM and x86 packages for Android, iOS, and Huawei’s emerging Harmony Next ecosystem, giving users a consistent conversational experience regardless of device vendor. Typical use cases include ad-hoc querying of self-hosted or cloud LLM APIs, quick prototyping of prompt workflows, and secure offline storage of chat histories through an embedded SQLite engine. The interface deliberately avoids vendor lock-in by exposing standard OpenAI-compatible REST endpoints, so academics, hobbyists, and enterprise testers can point Kelivo toward local models running on llama.cpp or toward commercial services such as Azure OpenAI without reconfiguration. Optional plugins add markdown rendering, syntax highlighting, and session export to PDF or JSON, making the client equally suitable for casual question-and-answer sessions and for preserving reproducible research transcripts. Although the catalogue is presently limited to this single title, the publisher’s emphasis on transparent source code, rapid iteration through GitHub Actions, and permissive MIT licensing signals an intention to cultivate an ecosystem of similarly streamlined utilities. Kelivo is available free of charge on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the latest build and supporting batch deployment alongside other applications.
