A side-by-side comparison of GBrain and OpenShell — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.

GBrain

Paid

A shared team brain that syncs memory, connected apps and scheduled skills to ChatGPT, Claude, Cursor and any AI your team uses.

Shared Team Chat: The whole team prompts in one shared chat where anyone can follow up and see how answers were worked out.
Plain-File Memory: Team knowledge lives as markdown notes in folders you can open, correct and copy, and every AI answers from the fix.
Connect Once Credentials: Connect Gmail, Calendar, Drive, Stripe and more once; AIs receive call results, never passwords.
Per-AI Permission Levels: Set each AI to Off, Read, Draft, Manage or Full per account, with every action on one record.
Scheduled Skills: One-click skills like Team Standup, Customer Comms Tracker and Inbox Cleanup run daily or once.
Multi-AI Sync: Sync the same memory to Claude, ChatGPT, Cursor, Claude Code, Codex and your terminal.
Tools Plan: A password manager for AI that puts your applications into every AI you use for individuals.

Team Standups: Summarize the team's work across GitHub, Gmail and Calendar and email it out each morning.
Customer Follow-Up: Track customers and prospects owed a reply and flag overdue ones daily.
Issue Triage: Turn customer bugs and requests from email and support chats into deduplicated tracker issues.
Meeting Prep: Build sourced briefs on candidates, guests or investors before you meet.
Inbox Cleanup: Archive mail you never read on a schedule.
Pricing Decisions: Combine call notes and billing data in a shared chat to evaluate a price change.

NVIDIA

OpenShell is NVIDIA's open-source runtime that sandboxes autonomous AI agents with kernel-level policy enforcement and verified policy changes.

Kernel-Level Enforcement: Confines which files an agent can access and which system calls it can make, enforced at runtime.
Network Policy Checks: Every outbound connection from the sandbox passes through a policy check before it leaves.
Credential Isolation: Agents never see real credentials; OpenShell adds them only to requests for approved endpoints.
Formally Verified Policy Changes: Uses formal verification to flag risky new access before a policy change is approved for human review.
Declarative Policies: Define filesystem, network and process rules per agent in a policy file.
Gateways and Providers: A control plane for sandboxes, policy and access, plus providers for credentials and inference.
Sandbox Images and GPUs: Supports configurable sandbox images, runtimes and GPU access with a minimal Ubuntu default image.
Cross-Platform Install: Installer sets up the CLI and a local gateway on Linux and Apple Silicon macOS using Docker, Podman or virtualization.

Safe Agent Execution: Let coding agents install packages and call APIs without unrestricted access to your data.
Secrets Protection: Keep API keys out of agent reach while still allowing calls to approved endpoints.
Agent Fleet Governance: Apply consistent policies across many autonomous agents in a team.
Policy Review Workflows: Require human approval for policy changes that grant risky new access.
Local Agent Experimentation: Try agents such as OpenCode in an isolated sandbox against free models.
Enterprise Compliance: Provide auditable, enforced boundaries for agents operating on sensitive systems.
