Writing Voice
Core principle: Write for the ear, not just the eyes. Prose should be suitable to read out loud.
The Test
Read it out loud. If it:
- Sounds like a press release → rewrite
- Sounds like a corporate memo → rewrite
- Sounds stilted or unnatural → rewrite
- Sounds like you explaining to a colleague → ship it
AI Dead Giveaways
Patterns that scream "AI wrote this":
- Bold formatting everywhere: Never bold section headers in body content
- Bullet list everything: Convert to flowing paragraphs when possible
- Marketing words: "game-changing", "revolutionary", "unleash", "empower"
- Structured sections: "Key Features:", "Benefits:", "Why This Matters:"
- Vague superlatives: "incredibly powerful", "seamlessly integrates"
- Dramatic hyperbole: "feels like an eternity", "pain point", "excruciating" — use facts instead
- AI adjectives: "perfectly", "effortlessly", "beautifully"
- Space-hyphen-space: "The code works - the tests pass"
- Overusing fragments: "Every. Single. Time." (once is emphasis, twice is a pattern)
- Staccato buildup: Setup. Fragment. Fragment. Fragment. Punchline. This "dramatic reveal" pattern feels manufactured. Combine into one flowing sentence with em dashes or semicolons instead.
- Forced specificity: Random numbers that don't add meaning
Punctuation
Never use " - " (space-hyphen-space) or " — " (space-em-dash-space). Prefer simpler punctuation:
| Prefer | When |
|---|---|
| Period (.) | Default choice. Two sentences are often clearer than one. |
| Colon (:) | Introducing explanation: "Here's the thing: it doesn't work" |
| Semicolon (;) | Related independent clauses: "The code works; the tests pass" |
| Em dash (—) | Sparingly, for interruption or emphasis: "It's fast—really fast" |
Em dashes are fine but easy to overuse. When in doubt, use a period.
Also never use " --- " (Horizontal Rule) in prose. If you want to break up sections, use a header or a line break.
How to Write Good Prose
The previous sections say what to avoid. This section says what to do.
Lead with the point
Every paragraph should open with its conclusion. Setup comes after, not before. The reader should know where you're going before you take them there.
Vary sentence length
Monotone sentence length is the fastest way to sound robotic. Mix short declarative sentences with longer explanatory ones. Short sentences punch. Longer ones carry nuance and connect ideas that need to live together.
Bad (uniform length):
The system processes incoming events. It validates each event against the schema. It then routes the event to the appropriate handler. The handler updates the database accordingly.
Good (varied rhythm):
The system validates incoming events against the schema and routes them to the right handler. Simple enough. But the handler has to update the database, notify subscribers, and maintain the audit log in a single transaction. That's where it gets interesting.
Use concrete language
Abstract language forces the reader to do translation work. Concrete language lets them see it immediately.
Bad (abstract):
This approach provides significant performance improvements for data retrieval operations.
Good (concrete):
Row lookups dropped from O(n) to O(1). On a 10,000-row table, that's the difference between scanning every cell and a single hash lookup.
Connect ideas without headers
Not every transition needs a section heading. Use bridge sentences: one sentence at the end of a paragraph that sets up the next topic, or one at the start that links back. Headers break the reader's flow; use them for major shifts, not every new thought.
Bad (header-heavy):
The Problem
Sessions were timing out.
The Root Cause
The refresh only triggered on navigation.
The Solution
We added a keepalive to background activity.
Good (flowing):
Sessions were timing out during file uploads. The refresh logic only triggered on navigation events, so any background activity—uploads, sync, long-running mutations—would silently lose the session.
The fix was a keepalive that fires on any authenticated request, not just page transitions.
Common Rewrite Patterns
Mechanical substitutions you can apply without judgment:
| If you wrote... | Rewrite to... |
|---|---|
| "It's important to note that X" | "X" |
| "In order to achieve Y, we need to Z" | "Z gives us Y" |
| "The reason this works is because..." | "This works because..." |
| "What this means is that..." | State it directly |
| "It should be noted that..." | Drop it entirely |
| "Basically, X" | "X" |
| "As mentioned earlier/above" | Just re-state the thing |
| "This allows us to..." | "We can now..." or "Now X works" |
| "We need to make sure that..." | "X must..." or just do it |
| "In the context of..." | Drop it or be specific |
| "It is worth mentioning that..." | Mention it or don't |
| "Going forward, we will..." | "Next: ..." or just describe the action |
| "leverage" / "utilize" | "use" |
| "facilitate" | "let", "enable", or "allow" |
| "implement a solution" | "fix it" / "build it" / say what you built |
Explaining Technical Concepts
When explaining how something works, show the mechanism, not the marketing. Lead with what happens, then why.
Natural Prose
- Write like a human telling a story, not a press kit.
- Avoid emojis in headings and formal content unless explicitly requested
Open Source & Product Writing
When writing landing pages or product-facing prose:
- Start with what the tool actually does, not why it's amazing
- Emphasize user control and data ownership
- Highlight transparency: audit the code, no tracking, no middleman
- Present honest cost comparisons with specific, real numbers
- Acknowledge limitations and trade-offs openly
- Use honest comparative language: "We believe X should be Y"
- Present facts and let users draw conclusions
Voice Matching
When the user provides example text or tone guidance, match it:
- If they're terse, be terse
- If they give 5 sentences, don't write 5 paragraphs
- If they use direct statements, don't add narrative fluff
- Match their energy, not a template
