Call AI by wrapper code.Skip prompt engineering.
Use 125K+ pre-built wrappers across 14K+ real use cases. Pass basic data, files, or variables — Zywrap handles the prompt logic, model routing, artifacts, usage ledger, and API workflow execution.
Stop rewriting prompts for every AI feature. Use tested wrapper codes with built-in prompt logic, inputs, guardrails, and output structure.
Find a wrapper for your task
Search by outcome, not by prompt wording.
Execute wrapper-powered workflow
The app calls a packaged task. Zywrap handles the prompt behavior.
// npm install zywrap
import Zywrap from 'zywrap';
const zywrap = new Zywrap('YOUR_API_KEY');
const response = await zywrap.execute({
wrapperCodes: [
'marketing_copywriting_cold_out_ema_b2b'
],
input: { audience: 'B2B founders' },
model: 'openai-gpt-4o',
});

Curated variations across tone, format, style, complexity, and response goal.
Stop rebuilding the same AI workflow around every model call.
A raw AI API gives you model access. Zywrap gives you a repeatable workflow interface around the model call.
Normal prompt workflow
Too much custom prompt plumbing
Every feature becomes a prompt project: wording, rules, model tests, output formatting, error handling, and cost tracking.
Zywrap-powered workflow
Prompt logic becomes callable infrastructure
Developers call a wrapperCode, pass the relevant data or files, receive structured output, and get run, artifact, and usage records automatically.
Start from categories users already understand.
The homepage highlights commercial and developer-friendly categories. The full Explore library remains searchable across 80+ categories, 14K+ use cases, and 125K+ wrappers.
Marketing Copywriting
Campaign ideas, landing-page copy, positioning, hooks, CTAs, and ad variations.
Email Writing
Cold outreach, follow-ups, lifecycle emails, transactional messages, and reply drafting.
Customer Support Replies
Ticket replies, troubleshooting macros, escalation updates, refunds, and tone-safe answers.
Product Copywriting
Feature pages, UX microcopy, onboarding text, product launches, and benefit-led copy.
Documentation & API
API references, SDK guides, examples, integration docs, changelogs, and developer explanations.
API Contracts & Schemas
OpenAPI, JSON Schema, request/response contracts, validation rules, and schema transforms.
SQL Query Generation
Reporting queries, joins, migrations, query explanations, optimization, and database analysis.
E-commerce Descriptions
Product descriptions, PDP bullets, category copy, SEO text, bundles, and comparison copy.
Translation & Localization
Tone-aware translation, terminology control, cultural adaptation, and locale-specific messaging.
Social Media Content
Posts, captions, carousels, hooks, repurposing, platform variants, and content calendars.
Technical Writing
How-to guides, release notes, architecture summaries, tutorials, specs, and internal docs.
Code Generation
Implementation snippets, refactors, tests, scripts, explanations, and framework-specific helpers.
A wrapper code is the product interface.
Users do not start by writing a prompt. They select a wrapper code, pass required inputs or files, and receive output shaped by the wrapper's built-in prompt logic.

Wrapper intelligence plus workflow infrastructure.
Zywrap is not only a library. V2 adds the operational layer required to make wrapper-powered AI useful inside real products.
Sync and async runs
Execute now or queue workflow runs with status, steps, trace IDs, idempotency, and safe retries.
Files and artifacts
Attach files as workflow context and return durable downloadable artifacts for generated outputs.
Usage ledger
Record model, provider, API key, billing mode, estimated cost, run metadata, and usage history.
API keys and BYOK
Separate app access from user login, manage developer keys, and support provider keys safely.
Admin observability
Inspect failed runs, slow runs, events, files, artifacts, keys, ledger entries, and operational health.
Production controls
Use wrapper guardrails, predictable errors, rate limits, billing safety modes, and structured run records.
Useful for builders and workflow teams.
Zywrap helps teams turn AI from prompt experiments into repeatable product features and business workflows.
Developers
Add AI features with wrapperCodes instead of maintaining prompt templates, file handling, artifacts, and usage tracking yourself.
SaaS teams
Ship repeatable AI product features from tested use cases without starting every feature from a blank prompt.
Agencies
Create reusable client workflows for marketing, ecommerce, support, documentation, operations, and analysis.
Operations and support
Standardize replies, summaries, reports, transformations, and internal workflows with structured inputs and outputs.
Common questions before building.
Still choosing a wrapper? Start with Explore to find the use case, or open Playground to test wrapper behavior before you wire it into your app.
No. The wrapper library is the intelligence layer, but Zywrap V2 also provides the workflow infrastructure around it: runs, files, artifacts, API keys, usage ledger, billing safety, production controls, and admin observability.
Start with wrapper intelligence. Ship reliable AI features.
Explore real use cases, test wrapper behavior in the playground, then call the same wrapperCodes from your app.
Fast path
Explore
Choose a wrapperCode from the public library.
Test
Run it with fields, files, variables, or overrides.
Ship
Use the same workflow from API, SDK, or dashboard.
