## 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

## Writingmate

Writingmate started as a ChatGPT-powered writing helper for email and messages, and has since grown into an all-in-one AI sidebar. The extension sits in the Chrome toolbar and opens with a click or the Cmd/Ctrl+M shortcut, giving you a chat interface without switching to a separate tab. Because it can read the page you are on, you can ask it to summarise an article, explain a paragraph, or turn what you are reading into a draft.

What sets it apart is model choice. Writingmate routes your request to GPT, Claude, Gemini or Grok, so you can pick whichever model suits the task — a long document, a coding question, a creative rewrite — or compare outputs. Alongside chat, it handles writing tasks like drafting and replying to email in Gmail, generating blog posts and marketing copy, fixing grammar, translating and summarising. Image generation is included as well.

The team behind it says it was built by people who previously worked at high-growth tech companies, and positions Writingmate as a lighter-weight alternative to tools like Wordtune and Jasper. The free tier is advertised as forever free, with a Premium upgrade for users who need more capacity.

**Pricing & Plans:** Freemium. A free tier is advertised as forever free, with an optional Premium subscription for higher usage and additional capabilities. Specific plan prices are not listed on the store page.

- **Multiple top AI models:** Switch between GPT, Claude, Gemini and Grok in one sidebar instead of paying for and juggling separate subscriptions.
- **Page-aware chat:** Ask questions about the article, document or page you are reading and get answers grounded in its content.
- **Writing and email drafting:** Draft or reply to Gmail messages, generate blog and marketing copy, fix grammar and rewrite text in seconds.
- **Translation and summarisation:** Translate across dozens of languages and condense long texts into short, readable summaries.
- **Built-in image generation:** Create images from a text prompt without leaving the sidebar or opening another tool.

**Strengths:** Access to several frontier models in one interface; Sidebar design keeps you on the page you are working in; Free tier that does not require a credit card to start; Wide language support, with the UI available in dozens of languages

**Limitations:** You depend on the extension's own model access rather than your own API keys; Advanced usage requires a paid Premium plan; Very heavy users may still prefer dedicated apps for each model
