Stack

Cloudflare AI Gateway + NVIDIA NIM + Mistral AI + Google AI Studio + Cloudflare Workers AI + Kilo Code Gateway + Ollama Cloud

A pipeline that parses messy multi-format logs into severity-aware clusters, exposes the clustered views as read-only MCP tools, and lets a LangGraph agent answer natural-language questions like 'only errors in payments' or 'show me the raw lines for cluster 7' in seconds.

Build time

A day to adapt the reference Colab to your log format

A durable orchestrator task breaks a news article into claims, fans them out to parallel worker tasks for source verification and historical analysis, then synthesizes a fact-check report.

Build time

2-4 hours for a prototype

Stack

Trigger.dev Scheduled Tasks + OpenRouter + Anthropic Startup Program

Crawl a docs site or help center into clean markdown with Firecrawl, embed it into a vector store, and serve a LangGraph ReAct agent that answers product questions with citations and self-refines its retrieval.

Build time

Half a day for a prototype

Stack

Firecrawl + LangChain + LangGraph + Qdrant

A Trigger.dev scheduled task that polls a YouTube channel every 8 hours, pulls transcripts, has Claude extract highlights as structured JSON, and emails a clean HTML digest via Resend — no database required.

Build time

1-2 hours for the single-channel version

Stack

Trigger.dev + YouTube Data API v3 + Anthropic | Claude + Resend + Upstash | Redis

A manager agent plans, delegates, and validates work across specialist agents (researcher, writer, editor) using CrewAI's hierarchical process, with tasks allocated at runtime rather than pre-assigned.

Build time

2-4 hours for a prototype

Stack

GroqCloud + OpenRouter + Qdrant Cloud Free Tier

A scheduled worker that crawls competitor sites and news sources with Firecrawl, has an LLM cluster and summarize the fresh items grounded in the scraped text, and assembles a curated newsletter draft with source links.

Build time

Half a day for a first newsletter

Stack

Firecrawl + Anthropic | Claude + Trigger.dev + Resend

A lead agent plans a research strategy, spawns parallel subagents with separate context windows to investigate different aspects simultaneously, then a citation agent attributes every claim — the orchestrator-worker architecture behind Claude Research.

Build time

1-2 days for a prototype

Stack

Anthropic Startup Program + Upstash | Redis + Qdrant Cloud Free Tier

A repurposing worker that scrapes a blog post or YouTube video with Firecrawl, then uses a LangChain chain to spin it into a LinkedIn post, a Twitter thread, and an email-newsletter section in one run.

Build time

2-3 hours for the first version

Stack

Firecrawl + LangChain + Anthropic | Claude + Google Docs API

A worker that generates unit tests for a source file, runs them, and only keeps tests that compile, pass, and measurably increase code coverage — iterating until it hits a target.

Build time

2-3 hours for a prototype

Stack

GitHub Actions + GitHub repository + OpenAI for Startups

A scheduled scrape-to-store-to-deliver pipeline: Trigger.dev runs a weekday cron that scrapes the top Hacker News stories through a Browserbase proxy, summarizes each with an LLM, and emails a formatted digest.

Build time

1-2 hours for a prototype

Stack

Trigger.dev + Browserbase + OpenAI + Resend

A CrewAI crew where a researcher agent searches and scrapes the web and an analyst agent normalizes the findings into a structured, deduplicated leads table written to CSV or a database.

Build time

2-3 hours

Stack

CrewAI + Firecrawl + Serper + OpenAI

An event-driven document-parsing pipeline that detects new invoice or receipt emails, extracts a structured schema with a LangChain extraction chain, and writes validated rows into a Postgres database.

Build time

2-3 hours

Stack

LangChain + OpenAI + Neon | Postgres

A scheduled job that scrapes the pages and sites you care about with Firecrawl, summarizes the fresh content with an LLM, and emails you a clean daily digest.

Build time

Stack

Firecrawl + Val Town Cron + Mistral AI (La Plateforme)

A CrewAI crew of specialist agents — an SEO analyst, a brand-positioning analyst, and a synthesis writer — that researches competitors in parallel and produces a coherent, fact-based strategic report instead of a single subjective prompt.

Build time

2-3 hours

Stack

CrewAI + Firecrawl + Serper + OpenAI

A scheduled task that scrapes a target site (e.g. Hacker News) on a cron, summarizes the top articles with an LLM, and emails or messages you a clean daily digest — a durable background job, not a fragile local script.
