## 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

## Vidnotes

Vidnotes is a small, focused tool rather than a general-purpose video suite. Published in the Chrome Web Store as Columbia Notetaker, it targets a specific academic workflow: Columbia recitation recordings. Students often need to revisit these sessions, but re-watching them in full is slow. The extension plays alongside the recording and produces AI-generated notes, condensing the content into reviewable form.

Because it works with recitation recordings specifically, the extension stays simple. There is no broad platform support, no credit system and no editing timeline — just an add-on that turns a recording into notes with timestamps so you can return to the source when you need detail.

The listing is free, sits in the Chrome Web Store's Education category, and the developer has declared that the extension does not sell data to third parties or use it for unrelated purposes. It is a niche tool, and its usefulness depends on whether you are working with Columbia recitation recordings.

**Pricing & Plans:** Free. The extension is available at no cost from its Chrome Web Store listing.

- **AI notes from recitation recordings:** Play a Columbia recitation recording and the extension drafts AI notes from the spoken content, so you do not have to transcribe it yourself.
- **Timestamped note taking:** Notes are tied to timestamps in the recording, making it easy to jump back to the exact moment a point was made.
- **Review-ready summaries:** Notes condense a full session into the key points, so reviewing before an exam takes minutes rather than hours.
- **Simple Chrome extension:** Installs as a lightweight Chrome extension that the developer states does not collect or sell user data.

**Strengths:** Free to install from the Chrome Web Store; Purpose-built for Columbia recitation recordings; AI notes with timestamps make review faster than re-watching; Developer states the extension does not collect or sell user data

**Limitations:** Limited to Columbia recitation recordings rather than general video sources; Small user base and a listing last updated in October 2024, so updates may be infrequent; Requires Chrome and the specific recitation recording setup to be useful
