/ FAQ

Common Questions

Do your tools make any API calls?
No. Every tool runs 100% in your browser. Your prompts, tokens, and data never leave your device. No accounts, no sign-ups, no rate limits.
Why is the Token Counter so accurate?
We ship two professional-grade tokenizers (js-tiktoken for OpenAI models and @anthropic-ai/tokenizer for Claude) directly in the page. All counting happens client-side.
How does the Prompt Quality Score work?
It analyzes your prompt across four categories — clarity, specificity, context, and structure — scoring each 0-25 for a total out of 100. It detects vague words, missing action verbs, and structural patterns.
Is the JSON ↔ CSV converter really private?
Yes — the conversion runs entirely in your browser tab using JavaScript. Your JSON or CSV is never uploaded, stored, or transmitted anywhere. Close the tab and nothing remains.
Are the n8n workflows really importable?
Yes. Each template generates a full n8n workflow JSON (nodes, connections, settings) in the exact format n8n expects. Download the .json and use n8n → Import from File, then attach your credentials (OpenAI, Gmail, Slack, Airtable, Sentry…) to the nodes that need them.
How often do you add new tools?
We add new tools based on community requests and our own workflow gaps. Check back monthly or follow the roadmap below.
Can I suggest a tool?
Yes — use our contact form or reach out on social. We prioritize tools that solve real operational problems for AI operators and agency owners.
