## GPTEnhancer

GPTEnhancer targets one of the most common friction points in ChatGPT: getting your own material into the conversation. Support for .txt, .js, .py, .html, .css, .json, .csv, .pdf, .png, .jpeg and .jpg files makes it useful both for developers who want help debugging or writing tests and for anyone who needs to discuss a document, a data table or a screenshot with the model.

The workflow is deliberately simple. A submit button in the ChatGPT page opens a file picker, then the extension breaks the file into manageable numbered chunks and inserts them into the chat. You can set the delay between chunks (eight seconds by default) and, on newer versions, type a custom prompt of up to about one hundred words that runs before the file content. A coloured button tells you where you are: yellow while uploading, green when the whole file has been submitted.

The extension runs locally in your browser and its listing states that it does not collect your files or data. It is a lightweight utility rather than a full chat client: it does not replace ChatGPT, add its own model, or expose an API. It simply makes the built-in chat a better place to work with files.

**Pricing & Plans:** Free. The extension is distributed at no cost through the Chrome Web Store and has no paid tiers; you still need your own ChatGPT account to use it.

- **File upload into ChatGPT:** Pick a file and GPTEnhancer inserts its contents into the current conversation as numbered chunks, giving the model your material as context.
- **Wide format support:** Handles text, markup and data files such as .txt, .md-style text, .js, .py, .html, .css, .json and .csv, plus .pdf documents and .png/.jpeg/.jpg images.
- **Paced chunk delivery:** A configurable delay between chunks (eight seconds by default) keeps submissions readable and reduces rate-limit or formatting errors.
- **Custom prompt box:** Add an instruction of up to roughly one hundred words that is sent before the file, so the model knows what you want done with the content.
- **Status feedback and local processing:** The submit button shifts from yellow to green to show upload progress, and the listing states no files or data are collected.

**Strengths:** Removes copy-and-paste friction when working with large files in ChatGPT; Covers both code formats and common document and image types; Adjustable chunk delay helps avoid truncated or jumbled submissions; Free, small footprint, and the listing states it collects no files or data

**Limitations:** Works only inside the ChatGPT web interface, not with other AI chat apps or APIs; Chunked uploading is slower than native file attachment and needs care around the Stop Generating button; Only three star-quality reviews and a relatively small user base, with no update since 2023

## 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
