## ChatGPT Optimizer

ChatGPT Optimizer (listed as Prompt Ready's ChatGPT Optimizer) is a browser extension for Chrome that adds a layer of convenience to the standard ChatGPT web app. Its headline feature is a one-click Optimize button that rewrites a rough prompt into a clearer, more specific question before it is sent, so you spend less time manually reworking wording.

Beyond prompt polishing, the extension tidies up long conversations: a Continue button asks the model to keep going without you typing a follow-up, Collapse controls shrink or expand individual chats so you can scan a long thread, and Auto Reveal expands truncated messages so you no longer hunt for a Show More link. The interface itself is also widened, with an expanded sidebar and full-width conversation area to use more of the screen.

The extension is a third-party tool distributed through the Chrome Web Store and is not affiliated with OpenAI. It is free to install, requires no account of its own, and the developer states that it does not collect or sell user data. Because ChatGPT's own interface changes frequently, some visual tweaks may behave differently over time.

**Pricing & Plans:** Free Chrome extension. No subscription or account is required by the extension itself; any ChatGPT plan you use is billed separately by OpenAI.

- **One-click prompt optimization:** An Optimize button turns a rough, loosely worded prompt into a clearer and more specific question before you send it.
- **Continue button:** Ask ChatGPT to extend an unfinished answer with a single click instead of typing 'continue' yourself.
- **Collapse and expand chats:** Shrink or open individual messages to get a bird's-eye view of a long conversation and a less cluttered workspace.
- **Auto Reveal of long messages:** Removes the friction of the Show More button so the full chat history is visible immediately.
- **Roomier layout:** An expanded sidebar and full-width conversation area make better use of a wide monitor.

**Strengths:** Optimize button reduces the effort of writing effective prompts; Continue and Auto Reveal speed up work on long answers; Collapse controls make lengthy conversations easier to scan; Free, lightweight (about 65 KiB) and requires no extra account

**Limitations:** Only rated by a small number of users, with a modest average score; Last updated in 2023, so newer ChatGPT interface changes may not be supported; Layout tweaks depend on ChatGPT's DOM and can break when it is redesigned

## 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
