Dinner sorted over text
Someone texts Instinct; Instinct asks your product for tables, with that person’s permission, and books one. An illustration of what Poppy is meant to allow.
Instinct
Be ready when Instinct opens its doors to products.
Instinct is the AI assistant people text to get things done. It has no integration program yet, but it is helping build Poppy, the Personal Agent Protocol. Flow Framework will support Poppy from day one.
Instinct has not announced a developer API. Poppy is a draft protocol; nothing is live on it yet.

The usual way vs. Flow
Today Instinct browses your website.
With Poppy, it asks your product.
Today, without Poppytoday
- Instinct reads your site like a person slow
- Breaks when the page changes fragile
- Signs in as the user, or gets blocked risky
- You can’t see or limit what it did blind
Reviews describe Instinct reaching companies by browsing their websites. Poppy is meant to replace that with agents that say who they are and act within limits the person sets.
With Flow Frameworkready
- Write your product’s jobs as tools1–2 hrs
- Serve them with sign-in (MCP)built in
- Poppy support when it shipsday one
import { tool } from "@flow-engineer/flow"; import { z } from "zod"; export default tool({ name: "find_tables", description: "Open tables for a party size and time.", input: z.object({ when: z.string(), guests: z.number() }), run: async (q) => api.tables.available(q), });

Each job is a TypeScript function with a typed input that calls your API: check an order, book a slot, find a deal. No protocol code.
Test it on simulated users
Run
npx @flow-engineer/flow test. Simulated users try the scenarios that matter, including people who change their mind or ask for something your agent should refuse.Serve it today
Flow serves your tools as an MCP server with each user’s sign-in, live in ChatGPT and Claude now.

Guide
Instinct and Poppy, explained.
What is Instinct?
Instinct is a personal AI assistant that people text or call to get things done, made by Spear Street Technology in San Francisco and invite-only during its beta, according to reviews. Forbes reported a $2.5B valuation weeks after launch.
Does Instinct have an API or integrations?
Not yet. Instinct has not announced a developer API or integration program, so products cannot plug into it directly today. We hope it opens integration support soon, and this page will say when it does.
Is Instinct part of Poppy?
Yes, as reported: PYMNTS lists Instinct among the design partners helping Meta and Sierra build Poppy, with Genesys, Rocket, Shopify, Stripe and Walmart. One account of Meta’s announcement lists other partners, and design-partner status is not a live implementation.
What is Poppy?
Poppy, the Personal Agent Protocol, is an open draft standard for how a person’s AI agent works with a company: the agent says who it is, and the person chooses whether it can view their account, make changes, or both. A company publishes one file describing how agents may connect. Read our explainer.
How does Flow help?
Flow Framework turns your product’s jobs into typed tools served with each user’s sign-in, and it will support Poppy from day one. Build once and you are ready for Instinct, ChatGPT, Claude and messaging apps.
