Hacker Sidekick is a desktop application that gives penetration testers, red teamers, blue teamers, and security engineers an AI environment purpose-built for cybersecurity work. Built on a VS Code-based interface, it combines an AI model fine-tuned for security contexts with agentic execution โ meaning it chains tools together and runs multi-step workflows rather than just providing advice.
Sovereign AI Unlike general-purpose AI assistants, Hacker Sidekick's models are built for cybersecurity work. The AI generates exploit code, analyzes malware samples, writes attack narratives, and works with offensive security terminology natively โ without the content restrictions that block legitimate security research.
Agentic Execution Hacker Sidekick executes workflows rather than just chatting. It chains tools like Nmap, vulnerability scanners, and custom scripts into automated pipelines, maintains context across an entire engagement, accesses the terminal on your machine, and produces structured output including reports and documentation.
Local-First Architecture Runs on Windows, macOS, and Linux. Integrates with tools already on your system โ Kali Linux, Burp Suite, WSL, Metasploit, and custom scripts. Data stays on your machine by default.
Use Cases Offensive: penetration testing, web application assessment, code analysis, threat emulation (MITRE ATT&CK), bug bounty reconnaissance. Defensive: alert triage, detection engineering, threat hunting, incident response, compliance reporting.
Deployment Individual download (free tier available), team deployment via SSO, and on-premises enterprise deployment with centralized management.

I can recommend Standard Notes as an alternative. https://standardnotes.com/ Works well on all paltforms, desktop and mobile. The sync works also great. It also backs up to text files on your computer, so that you can back up your files with your regular backup process and you can also easily move away if you would like to one day. - Source: Hacker News / 5 months ago
Standard Notes Official Website A super-private, encryption-first notes app worth checking out. - Source: dev.to / about 1 year ago
I havenโt used this service, but it does have some kind of integrated publishing feature. https://standardnotes.com/. - Source: Hacker News / almost 2 years ago
This certainly could be useful for me personally, but it would need more functionality. I think the _full_ project could be very useful though. However I would ask, how is this different from e.g. https://standardnotes.com/ and other note systems available ? - Source: Hacker News / over 2 years ago
