## Select AI

Select AI solves a very specific annoyance: the round trip of copying web text into a chatbot and pasting the answer back. With the extension installed, the text you highlight is already the prompt. You right-click, pick Select AI, and a panel opens where you can ask for a summary, a translation, an explanation, or a direct answer based on the selection. Because the extension is built around a bring-your-own-key model, you decide which AI provider handles the request and you keep control of the account and billing behind it.

The conversation model is what makes it more than a one-shot lookup. If you select three different paragraphs on the same page, the thread continues rather than resetting, so you can ask "what does this contradict?" and the assistant still has the earlier passages in view. That makes it useful for reading long articles, comparing claims across a page, or working through documentation where context accumulates.

Select AI is a small, single-purpose tool from an independent developer, last updated in May 2023 and used by a modest number of people. It is best understood as a friction-remover rather than a platform: there is no image input, no voice, no agent workflows, and no bundled model credits. If you already pay for an AI API and want that power one right-click away from anything you read, it fills the gap neatly.

**Pricing & Plans:** Free to install. Select AI does not charge for the extension itself; you connect your own AI API key, so any usage cost is billed directly by your chosen provider. No paid plans or subscriptions are advertised.

- **Highlight-to-ask via context menu:** Highlight any passage, open the right-click context menu, and choose Select AI to start an instant conversation about that text without leaving the page.
- **Bring your own API key:** Connect your own API key so requests go straight to the provider you choose, with no middleman and no mandatory account with the developer.
- **Multi-language conversations:** Ask and receive answers in multiple languages such as English, Spanish, Mandarin, French, and Hindi, instead of being locked into English.
- **Continuous conversation history:** When you select more passages on the same page, the earlier exchanges stay in context, so follow-up questions build on what you already discussed.
- **Privacy-first by declaration:** The listing declares no data collection, no selling of data, and no use of your data outside the extension's core functionality.

**Strengths:** Removes copy-paste friction: highlighted text becomes the prompt immediately; No subscription fee and no developer account required to use it; You control the API key and therefore the provider, model, and data path; Conversation continuity across multiple selections on the same page

**Limitations:** No new release since May 2023, so it may lag behind current model APIs; You must supply and pay for your own API key, and there is no built-in free tier; Feature set is deliberately minimal: chat about selected text, with no image input, voice, or agents; Very small user base and only one rating, so community support and troubleshooting help are limited

## 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
