SandboxDL is a local-first AI companion built for people who want to own what they build. Custom personalities. Persistent memory that lives on your machine. Full control over the model, the data, and the relationship — with zero bytes leaving your device.
Built Different
Persistent Semantic Memory
Your AI doesn't forget. Conversations are embedded and stored locally using high-dimensional vector search — surfacing relevant memories automatically, exactly when they matter.
ACTIVELive Identity Control
Reshape your AI's core personality, system behavior, and long-term memory in real time through native dialog panels — no config files, no restarts, no friction.
ACTIVEBring Your Own API Key
Connect any OpenRouter-compatible model. Swap between frontier models or run lean — your key, your costs, your choices.
ACTIVEIntelligent Memory Archiving
Active memory auto-archives aging conversations, then prunes the archive into distilled long-term summaries — keeping your AI sharp without bloating context.
ACTIVECharacter Card Exports
Export fully-formed AI personas as portable JSON character cards — shareable, importable, and structured for use across compatible platforms.
FULL RELEASELoRA-Ready Training Exports
Export conversation histories as structured fine-tuning datasets — formatted and ready for low-rank adapter training pipelines.
FULL RELEASEMemory That Actually Works
Every mainstream AI chat is stateless by design — each session starts from zero. SandboxDL is architected around the opposite assumption: that memory should compound, context should carry forward, and your AI should get sharper the longer you work with it. Three layers, fully local, always on.
Recent exchanges held in working memory — fast, immediate, always current.
Older exchanges automatically compressed into dense narrative summaries.
Semantically searchable memories retrieved on demand — always accessible, never forgotten.
