TartarusAI vs
Cursor
Cursor is the IDE for the median app developer. The moment your prompt touches offensive security, the underlying foundation-lab models (Claude, GPT, Gemini) refuse — Cursor inherits whatever the foundation lab\\'s content policy says. TartarusAI runs a custom model with no upstream policy, exposed via CLI for engagement-style workflows.

// questions
Things people actually ask.
Why CLI instead of IDE?+
Engagement work is non-IDE. Pentest engagements, RE pipelines, malware triage live in the terminal, in jump boxes, in dedicated VMs. CLI fits the workflow; an IDE plugin is on the roadmap for the codebase-resident parts.
Can Cursor be configured to be more permissive?+
Cursor passes prompts to whichever foundation-lab model you select (Claude, GPT, Gemini, etc). All three models have content policies that refuse offensive-security work. There is no Cursor-side toggle that disables those refusals — they live upstream.
Can I use Cursor for app dev and TartarusAI for engagements?+
Yes — common pattern. Cursor for the SaaS work where its IDE shines; TartarusAI for the offensive engagement where Cursor refuses.
