Instead of setting aside study time, you install the extension and keep reading the sites you already visit. Any English word on a page can be highlighted to see a translation, and one click saves it to your personal wordlist along with example context. The extension then does the passive work. Saved words are highlighted on other websites you browse, creating repeated exposure without extra effort, and Elia also recommends new words suited to your level, with the company claiming learners can pick up around 300 words a month. Daily goals, progress tracking, a 50+ language translation range and PDF integration round out the experience. Elia is a paid product with a 7-day free trial on all plans. Subscriptions run €5.99 per month or €49 per year, with a €249 one-time lifetime option. It is GDPR-compliant, works in Chrome, and requires an account so your wordlist syncs across sessions. **Pricing & Plans:** 7-day free trial on every plan; €5.99/month, €49/year, or €249 one-time lifetime. All plans include unlimited lookups, recommendations, practice, translations into 50+ languages and daily goal tracking. - **One-click word translation:** Highlight any English word on any webpage and see its translation instantly, with support for 50+ target languages. - **Personal wordlist:** Save words and phrases you look up so they build into a searchable, growing personal vocabulary library. - **Highlights on other sites:** Elia resurfaces your saved words on the websites you visit later, turning casual browsing into built-in review. - **Level-aware word recommendations:** Get new words suggested at your current level so you are always reading slightly above your comfort zone. - **Daily goals and progress:** Set a daily target and track how many words and phrases you have mastered over time. **Strengths:** Vocab review happens automatically inside normal browsing, so there is no separate study session; Translations, saved words and level-matched recommendations all sit in one small extension; Lifetime plan is a genuinely different option from the usual monthly subscription treadmill; Company states GDPR compliance and gives a 7-day free trial on all tiers **Limitations:** Chrome-only at the time of writing, so Safari, Firefox and mobile users miss out; Requires an account before you can save anything, which adds friction to a first try; Effectiveness still depends on you actually reading English-language pages regularly [Profile (Markdown)](https://openaitools.app/tool/elia.md) ## Sider Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight. Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel. Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base. **Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans. - **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab. - **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material. - **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move. - **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions. - **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits. **Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks **Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans [Profile (Markdown)](https://openaitools.app/tool/sider.md) ## Frequently Asked Questions ### How do Elia and Sider compare in monthly traffic?
