Your website. Your assistant. NevAI turns your public pages and custom answers into a configurable assistant with its own identity, a developer API and an embeddable widget. Built by NevetsInc with deterministic matching, without an external generative AI provider.

The Playground is live.
Build and test your website assistant for free. Your first production key starts a 90-day free trial with 5,000 responses per month. No card required.
Free testing includes 100 responses per day per installation. The Developer plan is listed at $2 USD/month; paid checkout is currently unavailable. Production pauses after the trial; your data is kept.
From website to working assistant
Make it yours, step by step.
Start in the Playground, then review what your assistant knows before connecting it to your website. Helping someone set it up? Read the machine-readable setup guide.
Create a local profile
Enter your developer details. The profile stays on this device; no password or cloud account is created.
Connect your website
Add your public HTTPS URL and assistant name. Save the separate recovery credential, then start learning from the Website tab.
Review and customize
Set your assistant identity and greeting. Review extracted answers, correct them and add your own questions and responses.
Enable tools and test
Choose the tools you need. Ask real questions in Test and inspect the intent, confidence and source.
Create your integration
Use a test key for server development. Verify your website before creating a production key, which starts the 90-day trial.
Publish and monitor
Embed the public widget or call the API from your server. Check Usage and Logs, then improve answers that fall back.
Your identity, your content and your response rules. NevAI provides the engine.
Give it your name and identity
Configure the name, company, role, greeting, tone, fallback and branding. Your visitors meet your assistant rather than a NevetsInc company bot.
✓Custom name, role and company
✓Greeting, tone and fallback
✓Widget title, avatar and accent
✓Optional Powered by NevAI attribution
Platform reference
Limits and behavior of the live Playground and API.
Privacy & control
Local developer details, minimal server data and explicit controls.
✓
Local profile
Developer profile details stay in localStorage. Assistant configuration, hashed credentials and usage live securely on the server.
✓
Secret keys
Raw API keys are shown once. Only hashes are stored; private keys belong on your server, never in widget HTML.
✓
Verified websites
Production activation requires domain verification. Widget sessions are restricted to the configured assistant and allowed origin.
✓
Grounded answers
Responses come from your configuration, indexed content or enabled tools. Low-confidence questions use your fallback.
✓
Compact logs
Request logs contain metadata by default. Storing unmatched question text requires opting in.
✓
Clear deletion
Delete knowledge separately from assistant identity. Clearing a local profile leaves production resources intact.
Before you start
Yes. The live Playground at /NevAi/playground lets you create an assistant, index your website, customize answers, test tools, create API keys and monitor usage.
Playground and test-key responses are free within the 100-per-day installation limit. Production use includes a 90-day free trial starting with your first production key: one assistant, one website, up to 500 pages, 5,000 responses per month and 30 requests per minute. No card is required. The Developer plan is listed at $2 USD/month, but paid checkout is currently unavailable. Production pauses after the trial; data is preserved and limited testing continues.
No. Your developer profile stays on this device. Server resources are protected by a separate management credential and recovery credential. Exporting a profile does not transfer server access; save the recovery credential separately.
NevAI uses deterministic lexical matching, intent rules, synonyms, typo tolerance, website content and enabled tools. It does not call an external generative AI provider. When confidence is too low, it returns your configured fallback.
