How it works
Three steps from zero to a fully deployed AI assistant.
Step 01
Add PDFs, Word docs, CSVs, Markdown, or paste any URL. Your assistant learns everything instantly — no coding required.
Step 02
Choose from GPT-4, Claude, Gemini, Mistral, and more. Or bring your own API key — you stay in full control of costs.
Step 03
Embed on your website, connect WhatsApp, Telegram, Instagram, or launch a voice agent — all managed from one dashboard.
Upload PDF, TXT, CSV, Markdown, or DOCX files. Manuals, contracts, onboarding guides, and support policies stop being passive documents and become structured assistant context your team can query instantly.
Add a URL and the platform ingests your help center, product pages, landing pages, and public documentation — keeping the assistant's answers aligned with what your website actually says.
Connect HTTP/SSE MCP servers to give the assistant real-time access to external data and actions. Tools are auto-discovered at runtime — Notion, GitHub, databases, custom APIs, and more.
Every source — files, URLs, and MCP tool outputs — is chunked, embedded, and indexed into one coherent retrieval layer. Mixed formats, different structures, single search space.
When a user sends a message, the engine semantically retrieves the most relevant chunks from your knowledge base and grounds the response in that exact context — not in model training data.
One knowledge core powers all your channels: web widget, WhatsApp, Messenger, Telegram, Instagram, and voice calls — every customer gets the same grounded, consistent response.
AI ENGINE
One source enters the engine at a time, travels through the processing tunnel, and emerges as a grounded assistant response the user can actually use.
Start from your live public knowledge surface.

"Define forbidden terms and custom instructions per workspace. The assistant's system prompt enforces brand voice, escalation rules, and topic restrictions on every single response."
"Token consumption, model cost breakdowns, provider usage history, and top conversations — all tracked per organisation with date-range filtering and granularity selectors."
"Understand which conversations your assistant resolves, which it escalates, and which knowledge base sources drive the most accurate answers — so you know exactly where to improve."
Testimonials
Teams across industries use Ask Nexora to deliver AI-powered support in minutes.
“We went live on a Friday afternoon. By Monday, the AI had handled 340 conversations and captured 28 leads — without anyone on the team lifting a finger over the weekend.”
Sarah M.
Head of Support · TechFlow
“We replaced Intercom for our support tier and saved $600/month. The MCP actions mean our AI actually books demos and creates tickets — Chatbase couldn't come close to that.”
James K.
CTO · DataNova
“WhatsApp, Instagram, and our website — all running from one dashboard. Support tickets dropped 65% in the first month. Our team now only handles the cases that actually need a human.”

No plans, no seats, no credit card, no usage bills. Add your own AI provider API key to switch on AI replies — without one, Nexora still runs as a full messaging inbox.

Without an AI key, Nexora runs as a real-time messaging inbox — your team reads and replies, everything stays in one place.
Humans answer. Nexora routes, stores, and organizes every conversation.
AI mode

Your key, your models, your bill. Swap providers anytime.
Free to create your workspace · Add an AI key whenever you're ready
How to get started
Three steps · Nothing to pay at any point
Create your workspace
Sign up in seconds. Nothing to pay, nothing to configure.
Add your AI key (optional)
Paste a provider key to turn on AI answers — skip it to stay in messaging mode.
Deploy everywhere
Drop in one line of code and connect your social channels.
Most users are live in under 30 minutes. Upload your documents or add a URL, configure your agent, copy one line of code onto your website — done. Social channels like WhatsApp and Instagram take a few minutes more to connect via webhook.
Nothing. Nexora is free — no plans, no seats, no credit card, no per-conversation fees. The only thing you can pay for is your own AI provider usage, and you pay that provider directly with your own API key. We never take a cut.
Web chat widget, WhatsApp Business, Instagram DMs, Facebook Messenger, Telegram, and voice calls (powered by Vapi). All channels share the same knowledge base and are managed from one dashboard — set up once, deploy everywhere.
MCP (Model Context Protocol) lets your AI agent take real actions beyond answering questions — book appointments, send emails, create support tickets, fetch live data, trigger workflows. This is what separates Nexora from basic chatbots like Chatbase: your AI doesn't just talk, it works.
Upload PDF, TXT, CSV, Markdown, Word (.docx) files, or paste any public URL. The platform processes and indexes your content automatically — no prompt engineering or technical setup needed. Update a document and your AI is instantly up to date across all channels.
Nexora keeps working as a plain messaging platform. You get the web widget and all social channels feeding into one shared inbox, with unlimited conversations, history, contacts, and lead capture — your team simply answers the messages. Add an API key later and the same inbox turns into an AI agent, no migration needed.
Nexora includes MCP action execution (Chatbase doesn't), covers all 5 channels with no per-channel charge (Intercom charges per channel), has no seat limits, and the platform itself is free — you only bring your own AI provider key. You get more automation for nothing.
Yes, at no cost. Turn it off in your widget settings and it displays only your company name and logo — fully on-brand for your customers.
The only AI assistant that answers AND acts across WhatsApp, Instagram, web, Telegram, and voice. Completely free — add your own AI API key to switch on AI, or run it as a plain messaging inbox.
