## Perspecteev

Perspecteev positions itself as a kind of media-literacy companion in the browser. You install the extension, land on a news article, click the icon, and within seconds you get a breakdown of the piece rather than just a verdict. Its data model is multi-criteria: political bias, political nuance, emotional polarity, linguistic complexity, clickbait intensity, citation and referencing practice, source reliability, language neutrality, relevance of statistics used, and source diversity. The combination is meant to reveal both what the article says and how it says it.

The extension was published by an individual developer and the Chrome Web Store description is written in French, suggesting an initial French-speaking audience, though the analysis is not inherently language-bound. It is distributed entirely through the Chrome Web Store with no separate account, dashboard or paid tier attached; the listing is small and early-stage, so the practical value is best judged by trying it on articles you already know well.

Because AI bias scoring is inherently approximate, Perspecteev is better used as a prompt for critical reading than as an authority. Treat the scores as a starting checklist — did this piece hedge its claims, does the headline match the body, are the sources varied — rather than as a definitive measure of an outlet's politics.

**Pricing & Plans:** Free. Perspecteev is distributed as a free extension through the Chrome Web Store; there is no paid tier described.

- **Multi-criteria article scoring:** Each article is graded across ten+ dimensions including political bias, emotional polarity, language complexity and clickbait intensity instead of a single true/false verdict.
- **Source and citation checks:** The extension evaluates source reliability, citation and referencing quality, statistical relevance and source diversity to expose thin or one-sided reporting.
- **One-click analysis in the browser:** Click the toolbar icon on any press article and results arrive in seconds with a score and short explanation for every criterion.
- **Neutrality and nuance detection:** Scores for language neutrality and political nuance help distinguish measured reporting from emotionally loaded or one-sided framing.
- **No account required:** Works straight from the Chrome Web Store listing with no sign-up, dashboard or profile to maintain.

**Strengths:** Covers many editorial criteria rather than a single bias or fake-news label; Free with no account or subscription friction; Install-and-use experience inside the browser where you already read news; Explanations accompany scores, so results are more than a number

**Limitations:** Small, early-stage extension with very few reviews; Chrome Web Store description is French-only, which limits discoverability for other audiences; AI-assigned bias and neutrality scores are approximate and should not be treated as authoritative

## 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
