TwoSlash

What is TwoSlash?
TwoSlash is a Chrome extension that drops ChatGPT into everyday text boxes across the web. Type // in a field on Gmail, Google Sheets, social sites, or code editors and the extension opens an AI command palette for rewriting, translating, summarizing, or generating content in place. Marketers, developers, and operators use it when they want ChatGPT-style help without copying text into a separate tab.
Browser chat sidebars are general purpose. TwoSlash focuses on inline triggers inside the field you are already typing in, with presets for emails, spreadsheet formulas, social replies, and code fixes. That makes it faster for repetitive micro-tasks than a standalone chat window, though it currently targets Chrome only while Edge and Firefox support are listed as coming soon.
The Standard plan runs on GPT-3.5 with up to 1,000 commands per month and no OpenAI API key required. A lifetime Bring Your Own Key tier lets you connect your own OpenAI credentials for unlimited commands and model choice including GPT-4. Feature requests go to support email, and the FAQ notes regular extension updates based on user feedback.
TimeComplexity.ai

What is TimeComplexity.ai?
Paste a function into TimeComplexity.ai and it returns Big O runtime complexity with plain-language reasoning. You drop in an algorithm snippet, and the site responds with notation like O(n log n) plus an explanation of why that bound fits the loops and recursion it sees.
Static analyzers usually need a full file with imports and a main block. TimeComplexity.ai accepts partial snippets in Python, JavaScript, Java, C++, Go, and other languages without headers or setup code. That makes it useful for interview prep and quick checks on isolated functions pulled from a larger codebase.
Developers, CS students, and interview candidates use TimeComplexity.ai to sanity-check algorithm bounds before submitting homework or reviewing pull requests. Anonymous users get 20 queries per day, signed-in users get 50, and the $5 per month Pro plan removes the daily cap.
