## GPT Based

GPT Based is a Chrome extension built around one clear idea: most disappointing ChatGPT answers come from weak prompts. The extension walks you through a short, guided form — the topic, your goal, the tone or format you want — and assembles that into a well-structured prompt you can paste into ChatGPT. It is a small tool with a narrow job, and it does that job for people who use ChatGPT regularly but have not settled into a prompt-writing habit.

Prompt quality is the whole point. Instead of firing off a one-line request like "write an email" and getting something generic back, you give the model enough context and instruction to produce something usable. The extension handles that structuring for you, so you spend your time on the task rather than on learning prompt engineering. It installs from the Chrome Web Store like any other extension and sits in the browser alongside ChatGPT, so there is no new interface to learn and no separate desktop app to manage.

A few practical notes. GPT Based is an independent third-party extension operated by the team behind gptbased.net — it is not an OpenAI product and is meant to complement, not replace, ChatGPT. It does not host its own chat interface: once the prompt is generated, the conversation happens in ChatGPT. The extension was last updated in May 2024 and has a modest user base of around 170 people, so community reviews and support resources are limited. Its Chrome listing also discloses that it handles website content, which is worth reading if you are careful about browser extension permissions.

**Pricing & Plans:** Freemium, Free

- **Guided prompt generation:** Answer a few guiding inputs and the extension assembles a clear, structured prompt you can hand to ChatGPT.
- **Better prompt structure:** Instead of vague one-line requests, GPT Based formats prompts with the context and instructions large language models respond to best.
- **Works where you already work:** Because it runs in the browser, you generate prompts while working in ChatGPT or any other tab without installing desktop software.
- **Free to install:** The extension is free to install from the Chrome Web Store and is offered by the operator of gptbased.net.
- **Declared data practices:** The developer declares that the extension does not sell your data to third parties or use it outside its core functionality.

**Strengths:** Removes the guesswork from writing prompts; Free to install from the Chrome Web Store; Runs in the browser alongside ChatGPT — no new app to learn; Useful for wrapping the model in a structured prompt with little effort

**Limitations:** Small user base (roughly 170) means fewer reviews and a thinner community; Depends on ChatGPT itself for the actual conversation once a prompt is generated; Handles website content per its privacy disclosure, which some users may want to review; Prompt templates are oriented towards ChatGPT specifically

## 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
