## Semaverse

Semaverse installs as a Chrome sidebar extension and works as a reading layer over the page you are already on. Instead of switching tabs to a summarizer, you open the sidebar and get a one-line takeaway, a fuller description, or bulleted highlights of the content in front of you. It also extracts structured quick facts about the people, organizations, locations and topics mentioned in a page, which is useful when you land on an unfamiliar company or author.

Beyond single-page summarization, Semaverse positions itself as a lightweight research and monitoring tool. Its Semaverse Intelligence feature lets you build a customized news feed and returns related articles drawn from hundreds of sources, with the option to filter by day, month or year so you can separate breaking news from longer-term trends. Because related links are generated automatically around what you are currently reading, the extension is aimed at market researchers, sales and marketing people, journalists and anyone tracking competitors or a fast-moving topic.

The listing presents the extension as free to use, and the developer publishes it under the semaverse.ai domain with a stated privacy position that it does not sell user data to third parties and only handles website content for its core functionality. Third-party review volume is small, so treat the summaries as a research aid rather than a substitute for reading primary sources.

**Pricing & Plans:** Presented as free in the Chrome Web Store listing, with no published paid tier. Visit the developer site for current terms.

- **Instant summaries at three depths:** Collapse any article, video or page into a single line, a full descriptive paragraph, or a bulleted list of highlights, depending on how much detail you need.
- **Quick facts extraction:** Automatically pulls out key facts about the people, companies, locations and topics that a page mentions, so you can size up an unfamiliar subject fast.
- **Related-content discovery:** Suggests relevant articles from hundreds of sources based on whatever you are currently browsing, keeping you inside the topic without extra searching.
- **Custom intelligence feed:** Build a personalized news feed around your interests and let Semaverse surface matching stories on a recurring basis.
- **Time-window filtering:** Filter news and trend results by day, month or year to distinguish fresh developments from longer-running patterns.

**Strengths:** Works inside the browser as a sidebar, so there is no tab-switching or copy-pasting; Offers three summary depths, from a single line to bulleted highlights; Quick facts panel adds structured context beyond a plain summary; Related-article discovery spans hundreds of sources with day/month/year filters

**Limitations:** Chrome-only, so Firefox, Safari and mobile browsers are not covered; Review volume is small, so real-world accuracy across many page types is still lightly tested; No publicly listed paid plan or API for teams that need programmatic access

## 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
