Proto-Mind vs Suprbox — Secure Storage for Autonomous AI Agents: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Proto-Mind and Suprbox — Secure Storage for Autonomous AI Agents — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Proto-Mind
VIRENCORE
A native macOS floating workspace that keeps AI conversations, project memory, files and live voice together on your Mac.
Key features
- Floating Cube Workspace: Hover the cube to reveal the workspace and click to pin it, or move away to hide it while tasks keep running in the background.
- Per-Conversation Model Routing: Each chat picks its own model and account — ChatGPT with Codex access, supported model APIs, or a local Ollama model.
- Editable Project Memory: Notes, decisions and preferences stay attached to a project and carry into later conversations, and you can review, change or remove any of them.
- Live Voice Control: Speak to open a project, steer a running task or send new work, and add a correction while the task is still going.
- Detachable Companion Windows: Pull out and resize a browser, a file or a second conversation so reference material sits beside the work.
- Explicit Mac Access: Codex can work with files and run commands only after you turn Mac access on; screen control additionally requires Codex Desktop's signed Computer Use helper.
- Local Data Storage: Conversation history and saved memory live on your Mac, and cloud processing happens only when you choose a cloud model or voice.
- Open Source Beta: The macOS installer and the Apache 2.0 source are both published, so the workspace can be inspected and built from source.
Best for
- Long-Running Project Work: Keep a website or client project's decisions in project memory so each session resumes instead of re-explaining the brief.
- Brief to Deliverable: Have the agent read a client brief and save a proposal document, then open it in a companion window next to the conversation.
- Parallel Task Execution: Start several tasks across different models at once and check back on them without blocking the conversation you are in.
- Hands-Free Steering: Dictate a correction or open a project by voice while your hands are busy elsewhere on the Mac.
- Privacy-Sensitive Drafting: Run a local Ollama model so conversation content never leaves the machine.
- Model Comparison: Put the same question to a Codex route and a local model in adjacent windows to compare the answers side by side.
Suprbox — Secure Storage for Autonomous AI Agents
Suprbox
Secure, purpose-built memory fabric that mediates document access and stores context and recall vectors for autonomous AI agents.
Key features
- Purpose-Built Memory Fabric: Provides a dedicated storage layer for agent context and state, optimized for storing and recalling contextual information used by autonomous agents.
- Vector Recall & Retrieval: Stores recall vectors and supports fast retrieval of context vectors so agents can access relevant context quickly during execution.
- Document Gateway: Sits between documents and agents to mediate reads and writes, preventing direct, uncontrolled agent access to source documents.
- Runtime Policy Enforcement: Enforces tight, fine-grained policies at execution time to control what agents can read, write, or execute against stored data.
- Execution Isolation: Isolates agent workspaces and memory to reduce risk of cross-agent data leakage and maintain separation between concurrent agent sessions.
- Controlled Context Delivery: Supplies agents only the allowed slices of context and vectors needed for a task, limiting exposure of sensitive information.
- Interposes between documents and autonomous agents to control access
- Purpose-built memory fabric for storing agent context and recall vectors
- Policy-driven execution and enforcement for agent operations
- Workspace isolation to prevent cross-agent data leakage
- Access controls and document-level gating for agents
- Designed for auditability and runtime visibility of agent access patterns
- Integrates with agent workflows to mediate reads/writes to storage
Best for
- Protecting enterprise document stores from autonomous agents by mediating agent access and preventing unauthorized reads of sensitive files.
- Providing persistent agent memory for multi-step workflows where agents need to store and recall contextual vectors across sessions.
- Enforcing runtime access policies for agents operating in regulated industries (finance, healthcare, legal) to maintain compliance and governance.
- Powering secure Retrieval-Augmented Generation (RAG) pipelines where agents retrieve vetted context vectors rather than raw documents.
- Isolating agent workspaces for research or development teams to experiment with agent behaviors without risking cross-project data leaks.
- Coordinating multi-agent systems by centralizing shared context and controlling which agents can access which pieces of memory.
- Prevent autonomous agents from reading or exfiltrating sensitive documents
- Store and manage agent context and memory vectors securely
- Enforce runtime policies for agentic workflows (who/when/how data is accessed)
- Isolate agent workspaces to reduce risk of data bleed between agents
- Provide a secure intermediary for LLMs and bots accessing corporate documents
