AI & DataSider
An AI sidebar that brings multiple LLMs into every tab and document you work in.
Sider is an AI productivity platform in the AI assistant and browser extension category, providing a persistent sidebar that integrates with Chrome, Edge, and major document and coding environments to give users access to multiple large language models including GPT-4, Claude, and Gemini in the context of whatever they are currently viewing. It is used by individual contributors, engineers, and knowledge workers at software companies who want AI assistance embedded in their existing workflow rather than requiring a context switch to a separate chat interface. The primary problem it solves is the friction of constantly copying text between work tools and AI chat products, which interrupts focus and makes AI assistance feel slower than just doing the task manually. Sider's page-aware context, document summarization, and chat-with-selection features let users ask questions about the content in front of them without leaving their current tab or tool. For engineers and product managers who read a lot of documentation, pull requests, and long threads, the ability to summarize and ask questions in context meaningfully reduces reading time.
Individual engineers, product managers, and knowledge workers at software companies who spend a significant portion of their day reading technical content, writing async communications, or doing research, and who want AI assistance embedded in their browser rather than in a separate tool. The right time to adopt Sider is when someone already uses ChatGPT or Claude regularly but spends too much time switching tabs and copying text to get useful responses.

Multi-Model Access in One Interface
Sider gives access to GPT-4, Claude, Gemini, and other models from a single sidebar, letting users switch between models for different task types without managing separate subscriptions or tabs. Teams that have strong preferences for specific models for specific tasks can use Sider as a unified access layer.
Page-Aware Contextual Chat
Sider reads the content of the current browser tab and lets users ask questions about it directly, without copying and pasting. This is particularly useful for reading long documentation pages, GitHub pull requests, or Notion docs where the user wants quick clarification or summary.
Document and PDF Summarization
Users can upload or link PDFs and long documents and get structured summaries, bullet-point extractions, or ask specific questions about the content. Engineers reviewing vendor technical docs, legal agreements, or research papers can compress reading time significantly.
Writing and Rewriting Assistance
Sider offers inline rewriting, tone adjustment, and expansion for text selected in any text field, covering email drafts, Slack messages, and documentation. This is more fluid than switching to ChatGPT because the assistance happens in the same window where the text lives.
Prompt Library and Shortcuts
Saved prompts and keyboard shortcuts let users trigger common AI tasks (summarize, explain, translate, rewrite formally) with a single key combination. Teams that repeat the same AI workflows daily save meaningful accumulated time by templating those tasks rather than retyping prompts.
Sider works as a Chrome and Edge extension and integrates with Google Docs, Gmail, and major web apps where text is written or read. In a typical productivity stack it sits alongside a team's primary AI subscriptions (OpenAI, Anthropic) as a workflow layer rather than replacing them, adding in-context access to the models the team already pays for.
Commonuse cases.
Reviewing and summarizing long pull requests or technical documentation
An engineer opens a large PR or an unfamiliar API reference and uses Sider to get a plain-English summary of what changed or what the documentation covers, without reading every line first. This is especially useful during code review sessions where understanding the intent quickly matters more than reading every diff character.
Drafting and editing async written communication
A product manager uses Sider to refine a spec, sharpen a Slack update, or restructure a project brief without leaving the tool they are writing in. The result is cleaner writing produced in less time, which compounds across the dozens of written artifacts a PM produces each week.
Accelerating research across unfamiliar technical topics
An engineer evaluating a new library, framework, or vendor reads through documentation pages with Sider open, asking clarifying questions as they go rather than Googling each term separately. This compresses the time from "unfamiliar topic" to "working understanding" for common engineering research tasks.
