## 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

## Skeptic Reader

Skeptic Reader is a browser extension for Chrome and Firefox that turns critical reading into something you can do at a glance. When you land on a news article or a video page, you click the plugin, and it reads the text (or the video transcript) and highlights rhetorical tricks: loaded language, cherry-picking, false dichotomies, appeals to emotion, and other logical fallacies. It then summarises what the piece argues and offers counter-arguments, so you have a more rounded view of the topic instead of only the author's framing.

Beyond flagging individual passages, Skeptic Reader produces a percentage-based 'Content Depth and Balance' score built from three signals: Balance (how evenly all sides are presented), Logic (whether arguments hold up), and Objectivity (how much is fact versus opinion). Video analysis extendds to YouTube, Vimeo, TED Talks, TikTok and other platforms by working from transcripts, so you can vet a clip before you decide to trust or share it.

The project is explicitly experimental. Domestic Data Streamers describe it as a public beta and an open experiment in using generative AI to provoke better questions rather than churn out more confident answers. It works best on standard news sites and blogs; paywalled articles, infinite-scroll pages, and very short pages can degrade results, and silent or caption-less videos may not be analysable at all.

**Pricing & Plans:** Free to install, with 10 free analyses included. After those run out you connect your own Mistral API key and pay Mistral directly for usage — Skeptic Reader itself charges nothing and stores none of the analysed text.

- **Real-time bias detection:** Highlights loaded language, framing, and one-sided presentation directly on the news article or page you are reading.
- **Logical fallacy identification:** Flags common reasoning errors such as false dichotomies, appeals to emotion, cherry-picking, and straw-man arguments as you scroll.
- **Counter-argument suggestions:** Offers opposing viewpoints and alternative angles so you can weigh a claim against more than the author's framing.
- **Video and transcript analysis:** Works on YouTube, Vimeo, TED Talks, TikTok and other platforms by decoding video transcripts for bias, fallacies, and conspiracy-style rhetoric.
- **Content scoring metrics:** Produces a percentage-based depth-and-balance score across Balance, Logic, and Objectivity, plus an AI-generated insight summary.

**Strengths:** Free to install with 10 complimentary analyses; Privacy-conscious: reads only the page you open, and no names, emails, or IPs are stored; Works on both Chrome and Firefox, plus video platforms via transcripts; Transparent that it is an experimental beta, not a definitive fact-checker

**Limitations:** Requires your own Mistral API key (and billing) after the free analyses run out; Struggles with paywalled pages, infinite-scroll sites, and very short articles; Desktop only — no mobile browser support
