TweetGPT Extension — AI Tweet Generator & Twitter/X Writing Assistant

Q: Does TweetGPT require Twitter API access?

For tweet generation (writing assistance), no API key is required — GPT-4o generates content directly. For analytics features (tracking which tweets performed best) and brand voice import (pulling historical tweets), Twitter API v2 with Basic tier access ($100/month) is required. The core writing assistant works without any Twitter API key.

Q: Can TweetGPT maintain my specific brand voice rather than generic AI tone?

Yes. The brand voice training system analyzes your past tweets to extract your unique patterns: the words you use, your typical sentence structures, how you use punctuation and emojis, your humor style, and your topic preferences. Every generated tweet uses this profile — making AI-generated content indistinguishable from your own writing to your audience.

1. Brand Voice Training from Historical Tweets

The extension imports the user's last 200 tweets via Twitter API v2, passes them to GPT-4o for voice analysis, and generates a brand voice profile summary — capturing vocabulary preferences, typical sentence length, humor/seriousness ratio, emoji usage patterns, and topic clusters. This profile is injected into every subsequent content generation prompt, ensuring generated content sounds authentically like the user.

2. Viral Hook Pattern Library

The extension maintains a database of proven viral hook structures (data hooks: "X% of people don't know...", contrarian hooks: "Hot take:", story hooks: "A year ago I...") and generates content using the most engagement-proven patterns for the given topic. GPT-4o generates 6 variants using different hook structures — the user selects the most resonant one.

3. Twitter/X Compose Box Injection

Twitter/X's compose box is a complex React contenteditable div with a custom input handling layer. The extension uses the React fiber node API to inject generated tweet text into the compose box — triggering the correct synthetic events so Twitter's character counter, emoji rendering, and URL shortening all update correctly as if the user typed the content.

4. Client-Side Vault & Zero-Leak Credential Hygiene

User API keys and proprietary system prompts are secured inside chrome.storage.session and isolated from the host webpage scope. The extension runs strict Content Security Policy (CSP) headers and sandboxed execution contexts, preventing unauthorized third-party scripts from reading session tokens or prompt payloads.
