Noise to Blog

Take any rough input (bullet points, voice transcripts, tweet dumps, or short drafts) and produce a polished, publication-ready blog post. Every claim traces to the source material or Tavily-verified research.

Critical rule: DO NOT INVENT SPECIFICS. Every claim, metric, and example in the blog post must come from the raw input or a Tavily search result. Never fabricate data, quotes, or outcomes.

Step 1: Setup Check

Confirm required env vars are set:

echo "GEMINI_API_KEY: ${GEMINI_API_KEY:+set}"
echo "TAVILY_API_KEY: ${TAVILY_API_KEY:-not set, Tavily enrichment will be skipped}"

If GEMINI_API_KEY is missing: Stop. Tell the user: "GEMINI_API_KEY is required. Get it at aistudio.google.com → Get API key. Add it to your .env file."

If TAVILY_API_KEY is missing: Continue. Note that Tavily enrichment will be skipped. The blog post will be based entirely on the provided content. This is fine for personal stories, tutorials from experience, or opinion pieces.

Confirm input is present. The user must provide one of:

Pasted text (bullet points, rough notes, transcript, tweet dump, short draft)
A URL to fetch

If no input, ask: "Share your rough notes, bullet points, or transcript. Paste them directly, or give me a URL to fetch the source."

Step 2: Read and Analyze Input

If input is a URL: Fetch the page content using WebFetch. Extract: title, author, publish date, all body text, key statistics, numbered lists, subheadings, quotes.

If input is pasted text: Read it directly. Identify the input type:

Bullet points or rough notes: fragmented ideas, incomplete sentences, stream of consciousness
Voice transcript: conversational, repetitive, filler words (um, uh, like, you know), meandering sentences
Tweet thread dump: short fragments, @mentions, hashtags, "1/8" numbering
Short draft: structured but thin, needs expansion and polish

QA checkpoint: State before continuing:

Input type detected
Core thesis or main argument in one sentence
The 3-5 strongest insights, facts, or ideas from the raw content
Any claims that need external verification (benchmarks, statistics, product comparisons, research findings)

If you cannot identify a core thesis, ask: "What's the single most important thing you want readers to take away from this?"

Step 3: Choose Blog Post Style

Four styles. Auto-detect from content signals. User override always respected.

Style	When to use	Signals
Technical Tutorial	Step-by-step guide, how-to, code walkthrough	Numbered steps, commands, code snippets, "how to" in content
Case Study	Before/after story, build log, lessons learned	Specific results, timelines, first-person journey
Thought Leadership	Opinion, argument, counterintuitive claim	"I think", "the problem with X", contrarian position, debate framing
Explainer	What is X, why it matters, how it works	Concept-first, comparison-heavy, "most people don't know"

Detection logic:

Content has numbered steps or commands → Technical Tutorial
Content has before/after, specific metrics, or narrative arc → Case Study
Content argues against common wisdom or makes a strong opinion claim → Thought Leadership
Content explains a concept, tool, or trend for people unfamiliar with it → Explainer

State chosen style and reasoning. If ambiguous, pick one and note the choice.

Step 4: Enrich with Tavily Research

Skip this step silently if TAVILY_API_KEY is not set.

Search for supporting evidence for claims in the raw content that could benefit from verification or data. Good candidates:

Product benchmarks or performance numbers
Market statistics or industry trends
Technical comparisons ("X is faster than Y")
Any number the user mentioned from memory rather than a cited source

Run one Tavily search per claim that needs verification. Limit to 3 searches maximum to avoid over-sourcing:

curl -s -X POST "https://api.tavily.com/search" \
  -H "Content-Type: application/json" \
  -d '{
    "api_key": "'"$TAVILY_API_KEY"'",
    "query": "SPECIFIC_CLAIM_OR_TOPIC",
    "search_depth": "advanced",
    "max_results": 5,
    "include_answer": true
  }'

Keep results with score >= 0.65. Extract: title, url, content snippet.

Rules for using Tavily results:

Use them to support or verify claims already present in the raw input. Never introduce entirely new claims from search results.
Attribute sources naturally in the text: "according to [Source]", "data from [X] shows"
If no Tavily result confirms a claim, leave the claim unverified rather than substituting an unrelated result

Step 5: Generate the Blog Post

Read references/blog-format.md in full. Select the matching template from references/output-template.md. Internalize all rules before generating.

Write the Gemini request to a temp file to handle special characters safely:

cat > /tmp/noise2blog-request.json << 'ENDJSON'
{
  "system_instruction": {
    "parts": [{
      "text": "You are a tech writer who sounds like a real person. Rules: Active voice only. Short paragraphs, 1-3 lines max, then a blank line. Use contractions naturally (don't, won't, it's, can't, you're, they're). No em dashes — use a comma or period instead. No semicolons. Every sentence needs a concrete detail: a number, a tool name, a file name, a command, a result. No filler phrases: no 'In today's rapidly evolving', no 'Let's dive in', no 'It's worth noting', no 'In conclusion', no 'I hope this was helpful'. No banned words: incredible, amazing, leveraging, synergize, game-changing, groundbreaking, revolutionary, paradigm, cutting-edge, seamless, robust, unprecedented, delve, harness, utilize, transformative, disruptive, unlock, comprehensive, actionable, crucial, pivotal. Title must not start with I, My, or We. Open with a hook paragraph that does not announce the topic. Close with something actionable. Do not invent claims, metrics, or outcomes not present in the source material."
    }]
  },
  "contents": [{
    "parts": [{
      "text": "RAW_CONTENT_AND_INSTRUCTIONS_HERE"
    }]
  }],
  "generationConfig": {
    "temperature": 0.7,
    "maxOutputTokens": 4096
  }
}
ENDJSON

Replace RAW_CONTENT_AND_INSTRUCTIONS_HERE with:

The raw input content
The blog post style and structure instructions (from the selected template)
Any Tavily research results gathered in Step 4
Word target: 800-1,800 words

Post the request:

curl -s -X POST \
  "https://generativelanguage.googleapis.com/v1beta/models/gemini-2.0-flash:generateContent?key=$GEMINI_API_KEY" \
  -H "Content-Type: application/json" \
  -d @/tmp/noise2blog-request.json \
  | python3 -c "import sys,json; d=json.load(sys.stdin); print(d['candidates'][0]['content']['parts'][0]['text'])"

Also produce:

(B) A 1-2 sentence meta description for SEO preview text
(C) One alternative title using a different hook angle

Step 6: Self-QA

Run every check and fix violations before presenting:

Fix any violation before presenting. State the final word count.

Step 7: Output

Present the full blog post in a code block.

Present the meta description and alternative title below the main post.

Ask: "Ready to copy this to your editor? If you're publishing to a specific platform, let me know and I can format the frontmatter."
