heysteff vs. SleekFlow, side by side
SleekFlow is an omnichannel conversational-commerce platform with a strong presence in APAC markets: WhatsApp and Instagram with catalogs and payments built into the chat, and automation configured through flows. heysteff starts from a different premise: a reasoning AI agent as the core, trained on your brand's tone and rules, that decides what to do in each conversation rather than following only a pre-built flow tree.
| Aspect | heysteff | SleekFlow |
|---|---|---|
| Channels included | WhatsApp (official and unofficial), Instagram DM, Messenger, Gmail, Shopify — one agent | WhatsApp and Instagram with a commerce focus: catalogs and payments built into chat |
| Conversation engine | Reasoning AI agent (LLM) that decides and executes actions | Configurable flow automation |
| Free plan | Real Free plan: 50 conversations/month, 1 channel, no card required | See their current pricing |
| Entry price | From $149/month, published USD pricing | See their current pricing |
| Setup fee | $0 | See their current pricing |
| Official Cloud API + unofficial number (Baileys) for numbers you already own | WhatsApp Business API | |
| Abandoned cart recovery | Native, integrated with Shopify (Pro plan and up) | Catalogs and payments built into the conversation (commerce focus) |
| Appointment scheduling | Yes, synced to Google Calendar (from Starter) | Not the product's central focus |
| Copilot mode | Yes, with "human echo" detection when a human already replied | Check directly |
| Region / language | LATAM, US and EU — built from LATAM, native Spanish and English | Strong presence in APAC markets |
| Per-workspace LLM choice | Yes — Anthropic, OpenAI, DeepSeek or OpenRouter, per workspace | Not a product axis (flow automation, not an LLM agent) |
| MCP server | Yes — Model Context Protocol so your own AI can configure the workspace | Check directly |
When SleekFlow may be the better choice
- Conversational commerce with mature catalogs and payments. If you need customers to buy without leaving the chat, through an established in-chat catalog flow, that's a product with a specific focus there.
- Your operation is in APAC markets. SleekFlow has strong local presence and support in that region, which can matter more than heysteff's LATAM/US/EU coverage.
- You prefer full control through visual flows. If your team wants to hand-design every conversation path, without an AI making autonomous decisions, a flow-based model can feel more predictable.
- You already have processes and a team trained on their flow builder. The switching cost of a complex automation already built there isn't trivial.
When heysteff is the better choice
- You want the AI to decide, not just follow a tree. heysteff's reasoning agent interprets the conversation and acts — replying, booking, recovering a cart — without every case being pre-wired into a flow.
- You sell in LATAM, the US or Europe and want a brand that speaks your language. heysteff is built from Santiago, Chile, for LATAM and the world, with native Latin American Spanish and English.
- You need to try it with no commitment. The Free plan (50 conversations/month, no card) lets you evaluate the real product before paying; entry pricing is published in USD, no fine print.
- You want to choose the AI model. heysteff lets you configure the LLM provider (Anthropic, OpenAI, DeepSeek, OpenRouter) per workspace, and exposes an MCP server so a customer's own AI can configure the system.
