## 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

## superReply

superReply is a browser extension that adds an AI reply assistant to the tools people already work in. Once installed and signed in, it appears directly inside Gmail and Outlook web inboxes, and it also works across LinkedIn, WhatsApp, Slack, Upwork and Fiverr. Instead of composing a reply from scratch you click into a message, let the extension suggest options, adjust the tone of voice to match the situation and send the version that fits.

The product is aimed squarely at people who answer the same kinds of messages all day: customer care agents, sales teams, freelancers juggling client threads and anyone who wants to clear an inbox faster. Its selling points are speed, tone matching and privacy. The extension only accesses the emails you explicitly choose to use it on, replies are not stored on superReply's servers, and the company says it applies industry-standard encryption.

The service is free to start, with up to 90 AI-powered replies per month at no cost. Paid plans remove that ceiling and unlock advanced tone controls, billed monthly or annually, and there are team plans for managing multiple seats. Each user installs the extension on their own browser with their own account so replies stay personalised, and cancellation is a one-click action from account billing settings.

**Pricing & Plans:** Freemium. Free to start with up to 90 AI email replies per month. Paid plans unlock unlimited replies and advanced tone controls, billed monthly or annually, with team plans available for multiple seats. Cancel anytime from billing settings.

- **Reply suggestions inside your inbox:** The extension appears directly in Gmail and Outlook web, so you never leave the thread you are answering.
- **Tone matching:** Pick the tone of voice that fits the situation — professional for a client, casual for a friend — and the suggestions adapt.
- **One-click smart responses:** A single click surfaces several ready-to-send reply options so you are never stuck staring at a blank compose box.
- **Works beyond email:** Beyond Gmail and Outlook, superReply integrates with Chrome, WhatsApp, Slack, LinkedIn, Upwork and Fiverr.
- **Privacy-first handling:** Replies are not stored on superReply's servers, the extension only reads emails you choose to use it on, and data is encrypted in transit.

**Strengths:** Free tier covering up to 90 AI replies every month; Lives inside Gmail and Outlook, so there is no new app to learn; Tone controls adapt suggestions to professional or casual contexts; Does not store generated replies on its own servers

**Limitations:** Requires installing a Chrome extension rather than working as a standalone web app; Advanced tone controls and unlimited replies sit behind the paid plans; Each user needs their own account, so team-wide rollout takes a little setup
