Detailed Analysis
StillHere.ink represents a growing category of user-built AI companion platforms that layer specialized functionality on top of existing large language model APIs. Developed and announced by an individual creator on Reddit's r/ClaudeAI community, the application is designed as a chat interface similar in surface appearance to ChatGPT or Claude's own web interface, but differentiated by its explicit focus on companion-style conversation and long-term continuity. Notably, the creator credits Claude as a collaborator in building the application itself, reflecting an increasingly common pattern in which AI systems are used as coding and development partners to produce software that in turn interfaces with AI systems. The app operates on a bring-your-own-API-key model, meaning users connect their own accounts from providers such as OpenAI or OpenRouter rather than paying a subscription to StillHere directly.
The application's feature set is specifically engineered around the challenges that make long-term AI companion use difficult within standard interfaces. Memory persistence, diary-style conversation summaries, rolling summarization, retrieval-augmented generation (RAG), and granular context controls are all included to address the fundamental limitation that most LLMs have no inherent memory across sessions. These features are not novel in isolation — numerous research projects and commercial products have tackled them — but their integration into a single, freely available consumer-facing tool is significant. The creator's approach to cost management is particularly pragmatic: by giving users direct control over model selection and context length, StillHere allows cost-conscious users to run extended conversations on inexpensive models while preserving the option to use higher-capability, more expensive ones selectively.
The economics described by the creator illustrate the rapidly shifting cost landscape of frontier AI models. Spending approximately $40 total across OpenAI and OpenRouter over several months for what appears to be substantial conversational use reflects how dramatically inference costs have declined. The specific callout of Qwen3 235B Instruct — a model from Alibaba's Qwen family — costing only $1.43 for extended use signals that open-weight and third-party models accessible through aggregator APIs like OpenRouter are increasingly competitive with closed frontier models for certain use cases, particularly conversational companionship where raw reasoning benchmark performance matters less than consistency, personality, and cost-efficiency.
StillHere's emergence also reflects a broader democratization of AI application development, in which individual developers without institutional resources can build, deploy, and distribute functional AI-powered products — in this case distributed as a progressive web app with an Android release in development. The platform's subreddit and Discord community suggest the creator is cultivating a user base around the product, following a pattern common to indie software projects that rely on community feedback loops for iteration. The fact that this was posted to r/ClaudeAI and explicitly credits Claude as a development partner positions the project within an active community of power users who view AI not merely as an end product to consume but as a tool for building new tools, compressing the traditional distance between user and developer in software creation.
