Frequently Asked Questions

What counts as an "analysis"?
An analysis is when Hallucinated.dev cross-checks your IDE's AI response against additional models. Free gets 1 model check, Pro gets 2, and Ultra gets 4 models cross-checking simultaneously.
What's the difference between Pro and Ultra?
Pro ($20/mo) gives you 15 checks/day, 2-model cross-checking, and 300 queries/month. Ultra ($50/mo) adds 40 checks/day, 4-model analysis, 1,500 queries/month, plus Knowledge Extraction, Premium Analysis (all flagship models), and API Access.
What happens if I exceed my limit?
Pro and Ultra users can enable Extra Usage for overage. Rates are $0.002/query, $0.02/analysis (Pro), $0.05/analysis (Ultra), and $0.03/health check. Free plans pause until the next cycle.
How does per-seat Teams pricing work?
Teams plans are priced per seat (2-20 members). Teams Pro is $25/seat/month ($20 if annual), Teams Ultra is $60/seat/month ($50 if annual). All team members share pooled query limits and get collaboration features like conflict detection.
What LLM providers do you support?
We support 16 models across 6 providers: OpenAI (gpt-5.2, gpt-5-mini, codex variants), Anthropic (opus-4.5, sonnet-4.5, haiku-4.5), Google (gemini-3-pro, gemini-3-flash), xAI (grok-code), Perplexity (sonar-pro), and Moonshot (kimi-k2). Higher tiers unlock more models.
Is my data used to train your models?
No. We do not use customer data to train models. Data is processed for analysis and then stored only for your Cross-Memory history (based on your plan's retention period).
Can I switch plans at any time?
Yes. You can upgrade or downgrade at any time. When upgrading, the new plan takes effect immediately with prorated billing. When downgrading, the change takes effect at the start of your next billing cycle. Annual plans receive a 20% discount.
How does IDE monitoring work?
Install the Hallucinated extension from your IDE marketplace (VS Code, Cursor, Windsurf, JetBrains). The extension hooks into your IDE natively to capture AI conversations, code changes, and session metadata without interrupting your workflow. For Claude Code CLI, a shell hook captures sessions automatically. Data syncs to the cloud and becomes searchable via the knowledge base.
