Free tools for AI, security and recruiting teams

Small, single-purpose tools from the teams that build Helix. Each one shows how it reaches its answer, with formulas and sources on the page.

AI platform teams
LLM VRAM calculator
How much GPU memory a model needs for its weights, key-value (KV) cache and runtime, and which GPUs fit it, with tensor-parallel sizes.
- Presets for Qwen3.8, GLM-5.3, DeepSeek, gpt-oss, Llama, Gemma and more
- Weights, KV cache and recurrent state priced from each model's config.json
- 12 NVIDIA GPUs from L4 to B200, plus Macs up to 512 GB
Recruiters
Boolean search string generator
Turn job titles, skills and exclusions into Boolean strings for LinkedIn Recruiter, LinkedIn search, Google X-ray and Bullhorn.

- Each platform's documented operator rules, with sources
- Title variants suggested for 19 common role families
Security teams
Penetration test report template
Fill in scope, methodology and findings with CVSS scores, then copy the report as Markdown or save it as PDF or HTML.
- Rules of engagement, limitations and retest sections, not just findings
- CVSS v3.1 scores computed with FIRST's equations
- Drafts stay in your browser; nothing is uploaded
