# Kronos AI > Kronos AI is an AI sales agent that runs your WhatsApp, Instagram, and Messenger conversations for you — qualifying leads, answering questions, following up, and booking calls, automatically and 24/7. Kronos AI replaces the manual, always-on work of a sales development rep (a "setter"): the person who replies to every DM, qualifies each lead, chases the ones who go quiet, and books the ones who are ready. A Kronos agent does that same work in seconds, in any language, at any hour, across every channel at once — without a salary, a schedule, or a training ramp. ## Who it's for Businesses that get inbound leads through WhatsApp, Instagram, or Messenger and lose them to slow replies — coaches, agencies, e-commerce, clinics, real estate, high-ticket services, and any team where a conversation is the path to a sale. If leads land at 11pm on a Sunday and cool off before a human answers, that is exactly the gap Kronos closes. ## What a Kronos agent does - **Replies in seconds, 24/7.** Any inbound message triggers the agent — no keyword required. Conversion drops sharply after the first few minutes, and Kronos answers instantly, every time. - **Qualifies against your own rubric.** Consistently, on every conversation, without the quality drift you get across different human reps. - **Answers from your knowledge base.** Upload catalogs, FAQs, pricing, and policies (PDF, docs, audio, video, images) and the agent responds with your real information, not generic guesses. - **Follows up with silent leads automatically.** Auto Follow-ups reactivate cold conversations with memory of what was already said. - **Takes real actions through integrations.** Save leads to Google Sheets, update a CRM, or run a custom MCP server mid-conversation. - **Understands what customers send.** Voice notes, images, video, and files — the agent reads and reasons over them. - **Hands off cleanly to a human** for the high-emotion closing call, with full context. ## Why teams choose it - **No missed leads.** Instant replies at every hour, on every channel, in parallel — no human schedule to lose leads to. - **One flat price, everything included.** $499 MXN / month (≈ $29 USD / month — same price, two currencies): up to 5 agents, 5 channels, and every feature. - **14-day free trial, no card required.** The first payment only happens on day 15, and only if you don't cancel first. - **Multi-model with automatic failover.** If one AI provider is rate-limited, the agent switches seamlessly — no downtime, no lost conversations. - **Your data stays yours.** Per-account isolation, encrypted connections, and secure authentication. ## Get started Create an agent, connect a channel (WhatsApp, Instagram, or Messenger), upload your knowledge base, and turn on Auto Follow-ups.

Reachable through MCP and as an open REST endpoint. ## Machine access for LLMs & agents Every documentation page has a clean markdown twin at `https://www.kronos.com.mx/docs/.md` (linked above). To search the docs semantically, there are two surfaces — pick by how you connect: - **Open REST endpoint (no authentication):** `POST https://api.kronos.com.mx/v1/docs/search` with a JSON body `{ "query": "...", "limit": 5 }`. Returns ranked documentation chunks by semantic similarity. Rate-limited per IP; intended for discovery. This is the right surface for an anonymous agent or a quick lookup. - **MCP server (requires an API key):** `https://mcp.kronos.com.mx/v1`, tool `search_docs`. Same semantic search, reached over the Model Context Protocol. The MCP requires a Bearer API key because the same server also exposes private account tools (sending messages, reading conversations); `search_docs` shares that gate. If you only need docs search without a key, use the REST endpoint above.
