Help: your top 10 questions
Short answers to the questions we hear most. Something missing? Email support@nexxtool.ai.
What does Nexxtool do?
It checks every reply your AI chatbot writes before your customer sees it. If a reply breaks one of your rules or gets one of your facts wrong, it gets fixed or held back, and you see why.
Which AI does it work with?
OpenAI, Anthropic, Google Gemini and Llama, or any AI that writes text.
How do I connect it?
Two ways. Point your chatbot at your Safe AI address instead of straight at the AI, or send each reply to our check API. Guided setup walks you through it in 4 questions.
What counts as one check?
One AI reply checked against your rules counts as one check. A knowledge check (comparing a reply against your own documents) also counts toward your knowledge-check limit.
What happens when a reply is blocked?
If it can be fixed, it’s fixed. If not, your customer gets your safe fallback line, like “Let me get a team member to help with that.” You see the reason in your history.
Can it stop private data from going out?
Yes. Turn on “Block private data” and replies with card numbers, US Social Security numbers or secret-looking keys get stopped.
What happens when I hit my monthly limit?
Checks pause until your next month starts or you upgrade. Every plan has a hard cap, so there’s no surprise bill.
Is there a free plan?
Yes: 1,000 checks a month, 1 connection, 50 knowledge checks and 1 document. Sign up between Nov 2, 2026 (UTC) and Feb 2, 2027 and you get 2,500 checks a month for your first 3 months.
How long do you keep my check history?
Free 7 days, Starter 30 days, Pro 90 days, Scale 365 days.
How do I reach you?
