Hybrid AI agents.
Built and run for you.
Others sell software. Callibre is the ecosystem.
One agent that answers the phone, replies on SMS and WhatsApp, works your DMs, and remembers the whole thread wherever the customer picks it back up. Behind it: in-house prompt builders and 24/7 support inside your own Slack. The platform plus the people.

A hybrid agent finishes the job.
Most callers never try twice. They call the next number. And the ones who do come back rarely come back the same way: they called yesterday, they text today, they DM on Saturday. Single-channel bots make them start over every time.
The call nobody picks up
Voicemail is not an answer. The lead books with whoever answers first, and that is usually not you at 7pm on a Saturday.
The bot with no memory
They explained it on the phone yesterday. Today they text and get asked the same four questions again. That is where trust dies.
The channel dead end
Your voice bot cannot send a text. Your chat widget cannot call. Every gap between them is a lead that stops moving.
The handoff that never lands
Qualified, tagged, and then sitting in a queue until Monday. A booking that happens two days late is a booking someone else already took.
Not a voice bot with a chat widget bolted on.
One agent, one memory, every channel. Voice, SMS, WhatsApp, Instagram, Facebook, email and live chat all run off the same conversation and the same context. The customer switches channels. The agent does not lose the thread.
People behind the agent, not just a builder screen. Our in-house team writes the prompts, loads the knowledge base, runs the QA suite, and stays in your Slack after launch. The agent escalates to your humans on rules you set, and never off a script it invented.
Enterprise agents need more than a login.
They need a team.
This is what working with Callibre actually looks like. You close the client. Everything after that happens in a Slack channel we build for you.
You sent two messages. The ecosystem did the rest: intake, knowledge base, prompts, QA, launch, and every 2 AM fix since.
You get a login.

The Full Ecosystem
Everything behind the saleA fulfillment engine behind every deal you close, so you can sign clients before you've hired anyone. The full operation, not just the AI.
The platform our team
runs under your brand.
Voice, chat, white-label and HighLevel-native, all underneath one hybrid agent. Our specialists own every layer. Nothing labeled Callibre, everything labeled yours.
Voice that doesn't sound like a robot.
Our specialists tune voice, prompts, and back-channeling per client. You don't touch a knob. Sub-second response, 800+ voices, custom clones. Inbound and outbound at concurrent scale.
White-label every layer.
Your domain. Your dashboard. Your client portal. Your billing. Even our specialists work under your brand. Clients never see Callibre.
Multi-channel chat with shared context.
Same conversation across voice, SMS, WhatsApp, Instagram, Facebook, email, and live chat. Our team wires the routing per client, so handoff happens without your customer re-explaining who they are.
Built for HighLevel
from day zero.
Snapshots install. Workflows trigger. Calendar, contacts, and opportunities sync. Our team owns the deployment per sub-account, so your GHL-trained operators don't have to learn a parallel universe.
Enterprise agent infrastructure.
Handled end to end.
Build, test, deploy, and observe enterprise-grade AI agents from one platform, with our team working alongside yours at every step, under your brand.
Configure, test, launch.
One control panel for your entire agent: persona, knowledge base, tool integrations, guardrails, and escalation rules. No code required.
Visual conversation flows.
Map qualifying logic, branching paths, tool calls, and booking flows as connected nodes you can see, test, and edit.
Monitor every interaction.
Score conversations in real time and inspect every tool call, API payload, and decision your agent makes, before your client ever asks.
AI summaries, transcripts, and playback.
Every call gets an AI summary, full transcript, and cost breakdown. Filter, replay, and QA every conversation, down to cost per booked appointment.
Providers go down.
Your agents don't.
Callibre runs on our own in-house LLM and our own hosting, not on someone else's API. When OpenAI or Anthropic have an outage and half the AI industry goes dark, your agents keep talking like nothing happened.
Plugs into the
stack you already run.
Native integrations across telephony, LLMs, CRM, calendars, and support tooling. 50+ live today, and our open API handles whatever else your stack throws at it.
They sell software.
Compare the ecosystem.
How Callibre stacks up against the other voice AI platforms on the things that decide whether a deployment survives: channel coverage, persistent memory, who does the building, and what a minute actually costs.

Competitor pricing and capabilities reflect each company's publicly published information and may change. The HighLevel band is metered by token at call time, so it moves per call. Their published rates bill the voice engine ($0.045/min), the speech line ($0.015 to $0.170/min), and telephony separately, then meter the model on top: $0.072 to $0.227 a minute in fixed lines before a single token. Our own receipts are here.

Enterprise-grade security,
built to pass their review.
Enterprise agents get enterprise scrutiny. The controls their security team asks about, spelled out, not buried in a badge wall. Encryption, access control, and signed agreements at every layer.
Encryption everywhere
AES-256 at rest, TLS 1.3 in transit. Keys managed and rotated. Recordings and transcripts never stored in the clear.

Resilience by design
99.99% uptime SLA with multi-region failover and a priority call queue. Peak volume never drops a conversation.
More than a platform.
Your profit center.
Every cost on this page is rebillable at the rate you set. We pass infrastructure through at what it costs us, you charge your client what the outcome is worth, and the spread is yours. Set the margin once and forget it.
Sell it as yours.
White-label portal, your pricing, your client relationship. A won client is a sub-account, not a rebuild. Your second client covers the plan.
Pick your plan.
Pay usage at cost.
Every plan opens the whole platform. The only thing that changes is how many client accounts you run on it. Usage is billed on top, itemized per minute, with no markup on any layer.

Everything in Agency. $0 a month.
Upgrade or start your HighLevel plan through our link and we comp your Callibre platform fee for as long as that subscription is active. You pay HighLevel what you were already paying. Most agencies stop paying $297 or more a month for the platform they were about to switch to, and get white glove onboarding on top.

- Usage at pass-through cost
Build your exact cost per minute.
Orchestration, the model you pick, telephony and add-ons. Every layer priced at what it costs us, on top of whichever plan you are on.
Pick how much you still
want to do yourself.
The plans above decide what software you get. This decides how much of the work stays on your desk. Everyone else in this category sells you a login and wishes you luck. You can hire our team to do the builds instead, and that is a service you buy, not a feature you hope is in the box.
You build it
For the operator who wants their hands on the build and knows what they are doing.
- Full platform access, unlimited hybrid agents
- 24/7 support from our engineers in your own Slack
- Migration from your current platform
- Usage at pass-through cost
We build it together
For the operator ready to step back, with our prompt team on the build alongside you.
- Our in-house prompt team builds your agents with you
- The Callibre acquisition snapshot
- Knowledge bases built from your docs and call recordings
- QA test suites run before every launch
We build it
Our team becomes your team. You sell and own the client relationship. We do the rest.
- A dedicated PM, AI builder and ops team on your account
- Full install and deployment under your brand
- We onboard each of your clients, per sub-account
- Managed support for your clients, answered under your brand
- Ongoing tuning from real transcripts as volume grows
You keep the client relationship and the retainer at every level. The only thing that changes is who does the building. Sign clients before you have hired anyone, and scale the delivery without scaling your headcount.
Frequently asked questions.
Everything a partner has asked us at least three times.
Hybrid means two things here. First, one agent runs every channel on one memory. It answers the phone, replies on SMS and WhatsApp, works Instagram and Facebook DMs, handles email and live chat, and remembers the whole thread wherever the customer picks it back up. Second, the agent is hybrid human and AI. Our in-house team builds and tunes it, and it hands off to your people on the rules you set.
Yes. If you upgrade or start your HighLevel plan through our affiliate link, we comp your Callibre platform plan for as long as that HighLevel subscription stays active. You pay HighLevel what you were already going to pay, the platform fee goes away, and you only pay usage at pass-through cost. Here is how it works.
We join your Slack or WhatsApp. When something needs fixing, you message the same thread your team already works in and a Callibre engineer responds, 24/7, across timezones. No ticket portal, no queue number, no "have you tried the docs."
Yes, and that is the part most platforms in this category do not offer at all. Your plan decides what software you get. Managed services decides how much of the work stays on your desk. On done with you, our in-house prompt team builds your agents alongside you. On done for you, a dedicated PM, AI builder and ops team run the builds, the deployment and the per-client onboarding under your brand, and we answer your clients' support tickets as you. You keep the client relationship and the retainer. Both are scoped on a call because the work varies with the size of your book.
No. Our in-house prompt building team builds and tunes agents with you, from first script to ongoing optimization as your client's volume grows. You focus on selling and the client relationship; the ecosystem handles the craft.
Full conversations, from understanding intent and pulling information to completing tasks like booking appointments, creating tickets, qualifying leads, and updating your CRM. Agents escalate to humans only when configured to do so.
Voice, SMS, WhatsApp, Instagram, Facebook, email, and live chat, with the same conversation and context shared across all of them. Handoff between channels happens without your customer re-explaining who they are.
Real. Your domain, your dashboard, your client portal, your billing, your support tickets. Callibre is invisible at every layer your clients see. Not a logo swap with someone else's URL underneath.
No. Sub-second response, 800+ voices, custom clones, and back-channeling tuned per client. Voice quality is the reason partners switch, and the reason their clients stay.
Two parts. A platform plan at $97, $297 or $497 a month depending on how many client accounts you run, and usage billed on top. Usage is itemized per minute at pass-through cost: orchestration, the model you pick, and telephony, with no markup on any layer. Upgrade HighLevel through our link and the platform plan is comped, so you pay usage only.
Nothing your clients will notice, because your agents don’t run on them. Callibre runs its own in-house LLM on its own hosting. Third-party models like OpenAI and Anthropic are available as optional routing, but they’re never a dependency. On telephony we run Telnyx and Twilio with redundancy between them. When the AI industry has an outage day, Callibre agents stay on the phone.
Guardrails, grounded knowledge-base retrieval, and escalation rules are configured per agent. Every conversation is scored and inspectable. You can QA every tool call and decision the agent makes.
You keep your clients. Contact data, conversation logs, and workflows export cleanly. Your client relationships are yours. No hostage-data tactics.
Not hard, because you don't do it. Migration support is included: our team ports your prompts, knowledge bases, phone numbers, and workflows, rebuilds them on Callibre, and QA-tests everything before cutover. Most migrations run in parallel with your existing setup so there's zero downtime.
Your workspace is live on day one. Most partners deploy and bill their first client inside two weeks. Our team builds alongside you from day one, drawing on agents we’ve already proven in your vertical.
