BetterPrompt

What is BetterPrompt?
Turn a three-word Midjourney idea into a full prompt with style cues, color notes, and --ar aspect ratio flags. BetterPrompt takes your short input, whether in English or one of 100 supported languages, expands it through a copywriting-style rewrite, and returns a longer version ready to paste into Midjourney.
General prompt helpers try to work across every image model. BetterPrompt is built only for Midjourney, so its rewrites add Midjourney-specific details like --ar aspect ratios and descriptive art-direction language rather than generic instructions.
The homepage shows before-and-after examples where a three-word idea becomes a multi-clause prompt with artist references and color palettes. New users start with 5 credits on the site. AI artists and designers who iterate on Midjourney concepts use it to skip manual prompt engineering.
Casper AI

What is Casper AI?
Casper AI is a Chrome extension for copywriting and research workflows that summarizes web pages and PDFs so you can brief articles, track policy changes, or scan deal documents without reading every word. It runs inside the browser, pulls text from the page you are on, and turns long sources into short notes you can share with teammates.
Where many sidebar assistants chase open-ended chat, Casper AI stays closer to analyst-style reading work. It highlights new insights from public sources, compresses news into shareable summaries, and focuses on understanding and distributing findings rather than generating full drafts from scratch. That narrow scope suits professionals who need quick comprehension more than long-form content generation.
The Chrome Web Store listing targets analysts, strategists, policymakers, and business developers who prepare for exams, research investments, work on deals, or track new laws. Version 0.4.2 lists about 10,000 users and a 4.4 out of 5 rating from 77 reviews, with English as the only supported language.
