## AI Chat Sync

AI Chat Sync starts from a practical observation: different large language models give noticeably different answers to the same question, and finding the best one means asking everyone. Doing that by hand is tedious - multiple tabs, the same text pasted over and over. This extension automates the chore. With one click it opens a chosen set of AI chat websites, and when you type a question into any one of them, that question is synchronised into the others.

Layout is treated as a first-class feature. You can open the sites as regular tabs, in a new window, or tiled horizontally, vertically or in a grid, which turns your screen into a comparison desk rather than a stack of hidden tabs. You can also batch-start fresh conversations across all of them at once and close the synchronised sessions in one action, either all of them or just specific ones, so cleanup does not become its own task.

It also stays flexible about which services you use. Beyond the predefined AI chat sites, you can add any other web page as a targets and set custom rules, or reuse the matching rules already included for existing chat sites. The extension collects no data and reports 276 users. One caveat worth naming: it drives the websites' normal interfaces rather than official APIs, so if a provider changes its page layout, synchronisation for that site may need an update.

**Pricing & Plans:** Free to install and use. There is no subscription, paid tier or in-app purchase, and the developer declares that no user data is collected.

- **Synchronised prompting:** Type a question into any one connected chat site and it is sent to all the others at the same time, so every model answers the same prompt.
- **Flexible tiling layouts:** Open the chat sites as tabs, in a new window, or tiled horizontally, vertically or in a grid for side-by-side reading.
- **Batch session controls:** Start new conversations across every site at once and close all or selected synchronised chats with a single action.
- **Add your own sites:** Register any web page as an additional AI chat target and write custom matching rules, or reuse the built-in rules for known sites.
- **No data collection:** The developer declares that the extension does not collect or use your data, and it only weighs about 665 KB.

**Strengths:** Removes repeated copying and pasting between chatbots; Tiling options make genuine side-by-side comparison easy; Add custom sites and rules instead of being limited to a fixed list; Free, lightweight, and declares no data collection

**Limitations:** Depends on the chat sites' interfaces, so layout changes can break sync for a site; Small user base, so less community testing than larger extensions; Interface is basic and geared towards power users

## 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
