## 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

## SurfMind - Smarter Browsing

SurfMind tackles a very common annoyance: you know you read something useful, but you cannot recall the site, the title or the date. Rather than making you dig through chronological history lists or nested bookmark folders, the extension accepts a plain-language description of the page you remember and returns the closest matches from your own local browsing data.

Under the hood it indexes visited pages and bookmarks as vector embeddings, which is what allows fuzzy, topic-level queries to work when exact keywords fail. A practical detail is browser-to-browser synchronisation: instead of signing into an account, you pair two browsers with a one-time code, so history and bookmarks can move between machines without a cloud login. Recent searches are retained so you can pick up where you left off.

Because the extension handles sensitive data — web history and page content, per its Chrome Web Store disclosure — SurfMind emphasises local storage and user control: you can clear history or bookmarks from the settings at any time, and the developer states data is not sold or used for unrelated purposes. The listing is published by docschat.in, and the extension has a small but real user base on the Chrome Web Store.

**Pricing & Plans:** Free. SurfMind is distributed as a free Chrome extension with no paid tiers listed.

- **Describe-it search:** Query your history and bookmarks with a topic, phrase or rough memory instead of an exact URL or page title.
- **Semantic matching with embeddings:** Visited pages and bookmarks are indexed as vector embeddings, so fuzzy queries still surface the right article or page.
- **Bookmark search by meaning:** Find saved pages by what they are about rather than hunting through folders and titles.
- **One-time-code browser sync:** Pair two browsers with a single code to move history and bookmarks across machines — no login or account required.
- **Local data control:** Clear your history or bookmarks whenever you want from the extension settings, keeping you in charge of your browsing data.

**Strengths:** Natural-language queries are far faster than scanning chronological history lists; Cross-browser sync without creating an account or signing in; Explicit user control over stored history and bookmark data; Free to use with no paid tier gating the core feature

**Limitations:** Requires broad access to browsing history and page content to work; Only available for Chrome-family browsers; Small user base and few reviews, so long-term support is harder to gauge
