## InFold

InFold is a browser extension aimed at readers who want more than the article in front of them. Instead of sending you to a separate research tool, it analyses the page you have open and presents a side panel with a topic outline, related articles, a timeline of sources that wrote about the same subject, and relevant keywords connected to common knowledge bases. The point is to get context without breaking your reading flow.

Its most distinctive piece is a chatbot fine-tuned for each topic rather than a generic assistant. That means the questions you ask are answered against the subject at hand, which suits deep-dives into a news story, a technical post or a policy document. The publisher is infold.com, and the extension is distributed through the Chrome Web Store with a small but clean record.

InFold has since grown beyond the extension: infold.com now fronts a daily news digest where AI agents read through a large number of news sources and email you personalised insights based on the interests you select. Adoption of the browser extension remains modest, and updates have been infrequent, but the publisher and domain are both live.

**Pricing & Plans:** The listing is a free Chrome extension. The publisher's broader product line is enterprise-oriented, so commercial pricing is handled through contact rather than a published self-serve price list.

- **Topic outline and related articles:** See how the piece you are reading is structured and what else has been written about the same subject, without leaving the page.
- **Per-topic AI chatbot:** Ask follow-up questions of an assistant fine-tuned for the topic in view, rather than a general-purpose model with no context.
- **Source timeline:** A timeline of other outlets that covered the same story, useful for tracing how a narrative developed.
- **Keywords linked to knowledge bases:** Relevant keywords are connected to common knowledge bases so you can jump from the article to background material.
- **Runs in the browser:** Installs as a Chrome extension and works alongside any article or post you open, with no separate workspace to manage.

**Strengths:** Context appears beside the article instead of in a separate tab or tool; The chatbot is tuned per topic, which suits focused deep-dives; Combines outlines, related articles, timelines and keyword links in one panel; Free Chrome extension with a clean publisher record

**Limitations:** Very small install base and only a couple of ratings, so real-world evidence is thin; The extension itself has not been updated recently; The broader business appears to lean toward enterprise and digest-style offerings rather than a consumer subscription

## 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
