Youtube Transcript Cleaner

Strategy: Remove entirely. Begin transcript where substantive content actually starts.

Commercial Content

• ALL advertising and sponsorship reads
• Product promotions, discount codes, affiliate links
• "Like and subscribe" requests
• Patreon/membership pitches
• Merchandise promotions
• Self-promotional content (unless central to topic)

Strategy: Remove completely with seamless reconnection of surrounding ideas.

Verbal Artifacts

• Filler words: "um," "uh," "like," "you know," "basically"
• Verbal tics and disfluencies
• Repeated false starts
• Conversational fillers: "right?", "I mean"

What Gets Preserved

• Speaker's original conceptual structure and argument logic
• Intellectual cadence (pace of idea development)
• Tone and voice authenticity
• Emphasis patterns (when pedagogically intentional)
• Load-bearing tangents (trim decorative ones)
• Specific examples, data points, anecdotes
• Speaker's conclusions (no editorial rewriting)

5-Step Methodology

Step 1: Parse

Read entire transcript to identify:

• Preview/teaser content (first 10-90 seconds)
• Where substantive content actually begins
• Central thesis and argument structure
• Commercial segments (ads, sponsorships, promotions)
• Speaker's tone and register
• Natural narrative shape

Step 2: Map Removable Content

Before drafting, mark boundaries:

• Preview content start/end
• Ad read segments
• Transition phrases into/out of commercial content
• Post-ad reconnection phrases ("so as I was saying")
• Plan how to reconnect conceptual threads after removal

Step 3: Draft

Compose in natural prose following speaker's sequence:

• Remove ALL preview and commercial content completely
• Begin at natural start of substantive content
• Replace filler with connective tissue honoring original pacing
• Strengthen transitions between ideas
• Maintain speaker's conclusions (don't editorialize)
• Elevate rhythm through sentence variety

Step 4: Verify

For terminology, proper names, and technical claims:

• Validate correct spelling and capitalization
• Confirm current accuracy (company names, product releases)
• Ensure technical terminology uses precise definitions
• Flag ambiguities or speaker misspeaking (note if present)

Do NOT alter speaker's meaning to fit verified facts. Preserve their statement and note discrepancies if material.

Step 5: Refine

Polish for readability:

• Verify preview removal is clean (natural start?)
• Confirm commercial removal is seamless
• Strengthen paragraph breaks where ideas shift
• Vary sentence length and structure for rhythm
• Ensure pronouns have clear antecedents
• Tighten redundancy while preserving intentional emphasis

Preview vs. Introduction

Preview (REMOVE):

• "In today's video, I'm going to blow your mind with..."
• "Wait until you see what happens when I..."
• [Jump cut to exciting moment from minute 12]
• "You won't believe what I discovered about..."
• "Today we're diving deep into [topic], and trust me, you'll want to watch until the end"

Introduction (KEEP):

• "I'm a researcher studying climate patterns, and today I want to discuss..."
• "Let's start with the fundamental question: what is machine learning?"
• "This video examines three common misconceptions about..."
• "Before we begin, here's some important context..."

The test: Does this content advance the intellectual argument, or is it trying to retain viewers? If the latter, remove it.

Commercial Content Removal

When ads/sponsorships detected:

1. Remove entire segment cleanly without narrative residue
2. Reconnect surrounding conceptual threads naturally
3. Do NOT leave placeholder text like "[ad removed]"
4. Ensure conceptual flow appears unbroken

Post-ad reconnection example:

• Before removal: "So the real problem is—but first, a word from our sponsor. [AD] So as I was saying, the real problem is resource allocation."
• After removal: "So the real problem is resource allocation."

Remove both the ad AND the reconnection phrase.

Output Format

# [Video Title or Central Thesis]

[Opening paragraph where substantive content begins]

[Body sections following speaker's conceptual flow]

[Conclusion/synthesis reflecting speaker's resolution]

---

*Note: All preview content, advertising, and promotional material has been removed from this transcript. The content begins at its natural intellectual starting point.*

Styling Guidelines

• Use H1 for title only
• Use H2/H3 only if speaker explicitly structures with sections
• Use emphasis (italic, bold) sparingly—only for genuine emphasis
• Use block quotes for speaker's direct remarkable statements (rare)
• Use footnotes [^1] for verification notes or clarifications

Quality Checklist

• ALL preview/teaser content completely removed
• Transcript begins at natural substantive content start
• ALL advertising and promotional content completely removed
• Commercial removal is seamless (no narrative residue)
• Post-ad reconnections handled cleanly
• Filler words systematically removed
• Verbal tics and disfluencies eliminated
• Original conceptual structure preserved
• Transitions strengthened (but not rewritten)
• Tone and voice authenticity maintained
• Terminology verified for accuracy
• Proper names capitalized correctly
• Readability elevated to written-essay standard
• Transcript flows as if preview/commercial content never existed

Edge Cases

Tangents: Keep if they illuminate the main argument or provide illustrative anecdotes. Trim if purely conversational filler.

Repetition: Keep if pedagogical (emphasis, different angle). Consolidate if redundant verbal repair.

Unclear audio: Note with [unclear: context suggests...]. Do not fabricate missing words.

Speaker error: Use corrected version. Omit false starts unless intellectually interesting.

Ambiguous commercial content: Ask "Is this advancing intellectual content or selling something?" If the latter, remove it.

Target Tone

The output should feel like:

• A thoughtfully transcribed lecture or conference talk
• An author's extended written essay on a deeply-known topic
• Professional but not sterile; precise but not pedantic
• Matching speaker's original register (conversational, formal, exploratory)
• Free from commercial interruption and retention gimmicks
• Beginning naturally where intellectual content begins
