Sip — A Word a Day

Sip a word a day. Look up words on any page, build your vocabulary, review with spaced repetition.

Sip turns passive reading into active vocabulary growth — one word at a time. ── HOW IT WORKS ── While browsing any webpage, highlight a word and right-click → "Sip this word." Sip instantly fetches the definition, phonetics, part of speech, synonyms, and an example sentence. The word is added to your personal word book with full spaced repetition scheduling. ── SPACED REPETITION REVIEWS ── Every day, Sip surfaces the words that are due for review based on the SM-2 algorithm — the same science behind Anki. Flip the card, read the definition, then grade yourself: Again / Hard / Good / Easy. Sip schedules your next review at exactly the right interval so you remember words long-term, not just overnight. ── VERB CONJUGATIONS & SYNONYMS ── For every verb, Sip shows all key tenses: base form, 3rd person, past, past participle, and -ing. Synonyms and antonyms appear automatically so you build richer word connections. ── YOUR WORD BOOK ── Browse, search, and filter all your saved words. Color-coded status shows what's due, what's coming up, and what you've mastered. ── LOCAL AI SUPPORT ── Optionally connect Sip to a local AI model (LM Studio, Ollama) or any OpenAI-compatible API for richer example sentences. No data ever leaves your machine unless you configure an external endpoint. ── PRIVACY FIRST ── All your words and settings are stored locally in your browser. No accounts. No servers.
