One-click training
Feed it your Business Brain.
Point the agent at your website and it reads the homepage plus the pages that say what you actually do, then drafts the Business Brain for you: what you sell, who it is for, why it wins. Drop in a pricing sheet or a playbook to sharpen it.
Give it a sender persona (a name, a role, a signature) and every email reads like it came from a real person on your team. No prompt engineering, no fine-tuning bills, and no AI key to buy: the AI is built in.
Real personalization
Every lead gets a letter. Not a template.
Mail-merge tokens fool no one: {{first_name}} is not personalization, it is decoration. Your agent reads what it knows about each harvested lead (their business, their city, their website) and writes an opener that could only have been written to them.
Test it before you trust it: the built-in console lets you pit your agent against any lead and read exactly what it would send, as many rounds as you need.
Per-lead personalization from real harvested context
Test console: audition your agent before it goes live
Tone control: from boardroom-formal to founder-casual
Test console: Agent vs. lead
Lead: Sunrise Dental Studio · Austin, TX
Hi Dr. Reyes, noticed Sunrise Dental’s reviews rave about your same-day crowns, but your site doesn’t take bookings after hours. We fix exactly that…

Make it shorter and end with a question
Hi Dr. Reyes, your patients love the same-day crowns. Want same-day bookings to match? Worth ten minutes this week?

You stay the closer
It drafts. You approve.
When replies land, the agent reads the thread and quietly drafts the answer in your voice, waiting in your inbox for a one-click approve or a quick edit. You keep final say; you just stop paying the blank-page tax forty times a day.
Under the hood, a multi-provider AI gateway with automatic failover keeps your agent online even when one model provider stumbles, or plug in your own API key (BYOK) and run it on your terms.
Out of the box
A full sales hire, minus the salary.
Everything your agent needs to research, write and follow up ships in the box, trained on your business, loyal to your voice.
Knowledge base
Upload playbooks, pricing and FAQs. The agent grounds every message in your actual material.
One-click training
Point at your website, click once, done. Retrain any time your business evolves.
Per-lead personalization
Openers written from each lead’s real context, never mail-merge decoration.
AI reply drafts
Incoming replies get a ready-to-send draft in your tone, waiting for one-click approval.
Auto-failover gateway
Multiple AI providers behind one switch: if one goes down, your agent does not.
Built-in AI, or your key
Works on day one with AI included. Prefer your own OpenRouter, Gemini or DeepSeek key? Connect it.
Sender persona
A name, role and signature per agent, so outreach reads like a person on your team wrote it.

Straight answers
AI Sales Agents, questions, answered.
Whatever you give it: your website content, uploaded documents (playbooks, pricing sheets, FAQs, up to your plan’s knowledge-base allowance) and the persona settings you choose. Leads Ranger distills this into a compact Business Brain that grounds every message the agent writes, so outputs reflect your real offer instead of generic AI filler.
Yes, that is the point of training. You set the tone, the agent learns your positioning from your own material, and the test console lets you audition it against real leads until the voice is right. For replies, drafts wait for your approval, so nothing leaves in a voice you have not signed off on.
Sequences you launch run automatically by design: that is outreach. Replies are different: the agent drafts responses and holds them for your one-click approval by default, keeping a human in the loop exactly where judgment matters.
No. AI is built into Leads Ranger, with automatic failover between providers, so a new account writes outreach on day one with no key. If you prefer direct control over model choice and spend, connect your own OpenRouter, Gemini or DeepSeek key and your usage runs on it.
Yes, in the useful sense of the term. An AI SDR researches a prospect, writes a personal first message, follows up on schedule and handles the first reply, which is exactly the loop these agents run, with your approval on replies. It is built for small teams: it is trained from your own website in minutes, sends from your own mailboxes and works alongside the lead finding and CRM in the same login.
No. Your documents and Business Brain are used solely to generate your outreach and replies. They are not used to train third-party models, and you can delete your knowledge base at any time.
