## Cluing

Cluing is a knowledge platform built for the AI era. Its core idea is that AI is only as useful as the context you give it, so Cluing focuses on capturing the insights you find during everyday work — while browsing the web, reading PDFs, watching videos, scrolling social feeds, or reading newsletters — and storing them in one organized space. A browser extension and mobile capture mean you can save a highlight or note with a keystroke instead of copy-pasting between apps.

Once saved, Cluing helps organize that material. It can suggest structure with chat, group related items, and use knowledge triggers to surface connections. The distinguishing feature is how the knowledge is used: Cluing positions itself as model-independent, so you can supply your saved context to any frontier model or custom agent through what it calls an AI Canvas and native MCP support, without switching tabs or losing context.

The interface highlights capture from many source types, AI-assisted organization, and a shared space where teams and agents draw on the same knowledge base. A free entry point is emphasized on the marketing site ("get it now it's free"), making it an accessible starting point for personal knowledge management, research, and team collaboration.

**Pricing & Plans:** Freemium: a free plan is advertised on the site ("Start for free"), with paid upgrades for teams and heavier use. Confirm current tiers on the pricing page.

- **Capture from anywhere:** Save highlights and insights from webpages, PDFs, videos, social posts, newsletters, Kindle, and email using a browser extension or mobile capture.
- **AI-assisted organization:** Let AI suggest structure, group related insights, and use knowledge triggers and chat to keep your base tidy and searchable.
- **Model-independent context:** Feed your stored knowledge to any frontier model or custom agent via an AI Canvas and native MCP, so your context travels with you.
- **Shared team knowledge base:** Build a common context space that both people and AI agents draw on for research, feedback, and collaboration.
- **Desktop and mobile working:** Capture and review insights on the go or at your desk, with a Chrome/Opera-friendly extension.

**Strengths:** Captures insights from a wide range of sources with minimal friction; Works with any AI model, avoiding lock-in to a single vendor; Free entry point makes it easy to start; Shared space supports both human and agent collaboration

**Limitations:** Value depends on building the habit of capturing consistently; As a newer product, integrations and features are still expanding; Advanced team and agent workflows may require a paid plan

## 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
