177 upvotes · #7 Product of the Day · Launched May 19, 2026 — View on Product Hunt
A Chert review uncovers how this platform lets you build AI agents that text customers in iMessage—without hiring support staff. If you’re running a service business, e-commerce brand, or concierge operation and most of your high-value customers carry iPhones, Chert offers a native blue-bubble channel for conversation that feels personal and immediate. Let’s dig into what it delivers and whether it fits your stack.

What Chert Does
Chert is an AI agent platform purpose-built for iMessage conversations. You configure a system prompt, tone, and knowledge base, and Chert deploys a conversational agent that replies to incoming messages in iMessage directly. The agent can handle customer service questions, capture inbound leads, manage refunds, or run any workflow you script—all in the native Apple Messages app that most affluent customers already use daily. There’s no app download friction and no SMS character limits.
The platform integrates bidirectionally with major CRMs like HubSpot, Close, and Pipedrive, so conversation history syncs back automatically. You can also build custom workflows using webhooks and API calls. Chert sits between your iMessage customers and your backend, translating natural language into actions—whether that’s retrieving an order status, scheduling a callback, or logging feedback into your support system.
Chert Key Features
Core capabilities that distinguish Chert in the messaging space:
- Native iMessage AI agents — Deploy conversational agents directly into Apple Messages, avoiding app fatigue and SMS overhead.
- CRM bidirectional sync — Automatically write conversation history, customer data, and outcomes back to HubSpot, Close, Pipedrive, and other platforms.
- Custom system prompt configuration — Define agent tone, guardrails, and knowledge base without coding; fine-tune behavior on the fly.
- Webhook and API integrations — Trigger backend actions (database updates, third-party API calls, payment processing) from conversations.
- Apple Business Register support — Operate under your brand identity in iMessage, building trust and recognizability with iPhone customers.
Who Should Use Chert
Chert is strongest for concierge services, premium direct-to-consumer (DTC) brands, and luxury consumer businesses targeting iPhone-first customers. If your revenue per customer is high enough that losing customers to SMS friction matters, iMessage native messaging is worth the investment. Examples include jewelry concierge, luxury resale platforms, bespoke tailoring, premium beauty services, and high-ticket SaaS onboarding teams.
Businesses operating in cost-sensitive, high-volume segments (e.g., fast food, budget retail, mass-market logistics) may find the iOS-only customer reach too limiting. Chert is not a replacement for SMS; it’s a complement for brands whose customers spend significant time in iMessage and value that channel over email or WhatsApp.
Chert Pricing and Plans
Pricing details are not yet publicly documented on standard pricing pages. For current rate cards, feature limits, and per-conversation or monthly billing structures, check the official Chert website or Product Hunt profile. Early-stage pricing often shifts as the product matures, so confirm minimums and overage fees directly with the team.
Chert vs Alternatives
Twilio dominates SMS customer messaging but enforces 160-character limits and lacks the native prestige of blue bubbles. Sendbird and Front handle cross-channel conversations (SMS, email, web chat, social) but neither specializes in iMessage or ai-native workflows. Chert’s core differentiator is that it marries iMessage’s brand magic with AI agents that don’t require extensive configuration—you drop in a prompt and go. If your customers are Instagram influencers, high-net-worth individuals, or luxury shoppers, iMessage is where they live and what they trust; SMS often feels cold by comparison.
Pros and Cons
Pros:
- Native channel prestige. iMessage blue bubbles carry brand weight SMS never will; customers perceive conversations as more trustworthy and personal.
- No app friction. Messages appear in the default Messages app; zero download or permission overhead.
- Seamless CRM sync. Conversation data flows automatically into HubSpot, Close, and Pipedrive without manual log entry.
- AI-first architecture. Built from the ground up for conversational agents, not bolted-on automation; prompt configuration is straightforward.
Cons:
- iOS-only customer reach. You cannot message Android users; this limits total addressable audience and may fragment your customer base across channels.
- Apple API approval and moderation. Chert must stay compliant with Apple’s Business Register guidelines; disapproval or policy changes could impact your operations.
- Early-stage product maturity. Fewer third-party integrations, fewer use-case templates, and smaller community compared to Twilio or Sendbird; documentation and edge-case handling may lag.
The Chert Review Verdict
This Chert review finds a genuinely specialized product: if your customer base skews affluent, iPhone-native, and values high-touch service, iMessage AI agents unlock a channel competitors often ignore. Chert’s onboarding is faster than Twilio’s, and the brand effect of blue bubbles is real. The tradeoff—iOS-only reach and Apple’s approval overhead—is a feature, not a bug, for luxury and concierge verticals. For mass-market or Android-heavy businesses, stick with SMS. For everyone else, running a Chert pilot against your iPhone customer segment is a low-risk way to explore higher engagement and shorter customer lifetime value payback.
FAQ About Chert
Can Chert handle outbound campaigns or only inbound support?
Chert handles both. You can configure agents for inbound customer support, but you can also initiate outbound iMessage conversations for follow-ups, re-engagement, or proactive service. API and CRM integrations let you trigger outbound campaigns based on customer events (purchase, cart abandonment, etc.).
Does Chert work with Android users or only iPhone?
Chert is iMessage-native and only reaches iPhone users. Android users won’t receive iMessage conversations; you’ll need a fallback channel (SMS, email, web chat) for cross-device coverage.
How long does it take to deploy a Chert agent?
Deployment is quick—typically 15 to 30 minutes for simple agents. You define a system prompt, upload a knowledge base (FAQ, product specs, policies), and configure CRM integrations. More complex workflows that require custom backend actions may need engineering review, adding a few days for approval and testing.
