What the app can do

Search and fetch

Use standard search and fetch tools to retrieve API docs, pricing, launch guides, and cron education content inside ChatGPT.

Build schedules

Turn a recurring workflow into a cron expression, retry posture, and webhook threshold recommendation.

Skill layer

MCP prompts and resources act as the first ChatGPT skill surface for schedule design, launch copy, and alert-policy guidance.

Explain cron

Parse a cron expression and preview the next scheduled run times in your target timezone.

Plan alerts

Recommend retries, failure thresholds, and disabled-job escalation for webhook-driven automations.

Why this is the right first version

The current app is intentionally public and read-only. That keeps the MCP server safe to expose, simple to connect, and easy to index.

For actual job creation and account-level actions, the next step is OAuth-backed identity. Until then, this release focuses on planning quality, product discovery, and answer-engine visibility.

That tradeoff is pragmatic: the app becomes usable in ChatGPT now, while the core SimpleCron dashboard and API remain the place for authenticated job management.

AEO and search surface

Dedicated ChatGPT landing page and a focused blog article around ChatGPT, MCP, cron automation, and webhooks.

Structured answers

FAQ schema, software application schema, and plain-language summaries built for answer engines and LLM retrieval.

LLM routing

Query fit

The copy now targets queries like ChatGPT cron scheduler, MCP cron server, and webhook automation with ChatGPT.
