My API Sider is a free Chrome browser extension designed for developers, researchers, content creators, digital marketers, and AI enthusiasts who want direct, unmediated access to the world's best large language models. Unlike subscription-based AI tools that charge you monthly fees and impose usage limits, My API Sider connects directly to AI provider APIs using your own API keys — meaning you pay only for what you actually use, at provider rates, with zero markup.
The extension opens as a sleek sidebar panel within your Chrome browser, giving you an AI chat interface that is always accessible without switching tabs or losing context. Whether you are writing code, researching a topic, drafting content, or solving complex problems, your AI assistant is always one click away.
My API Sider supports an extensive list of AI providers and models, making it one of the most flexible AI tools available for Chrome. Here is a breakdown of the major providers:
The fundamental principle behind My API Sider is BYOAK — Bring Your Own API Key. You obtain API keys directly from AI providers (usually free to start), paste them into the extension's settings, and start chatting immediately. This model gives you full control over your AI spending, complete transparency, and zero vendor lock-in. You can switch models and providers instantly, always getting the best performance for your specific task.
Create unlimited API profiles, each with its own provider, model, API key, custom system prompt, and parameter settings. Switch between a creative writing assistant, a coding expert, a research analyst, and a customer service agent in seconds — all within the same extension, no switching tools.
My API Sider uses server-sent events (SSE) streaming to display AI responses token by token as they are generated — the same way you see responses appear in ChatGPT and Claude.ai. This gives you a responsive, premium AI chat experience with no waiting for complete responses.
For models like DeepSeek R1, Claude 3.7 Sonnet, and OpenAI o1 that use extended reasoning/thinking, My API Sider automatically captures reasoning tokens and displays them in a beautiful collapsible "💭 Thinking Process" panel — so you see the model's reasoning pathway without cluttering the final answer.
Enable Web Search mode to ground AI responses in live internet data. When you ask a question with web search active, the extension fetches relevant web results and includes them as context for the AI — giving you responses backed by current, real-world information rather than just the model's training data.
Attach PDF documents, Word files, spreadsheets, code files, images, and more directly to your chat. The extension processes files locally in your browser, extracts the content, and sends it to the AI for analysis. Get instant summaries, Q&A, code review, data extraction, and more from your own documents.
My API Sider is built for anyone who uses AI regularly and wants more control, flexibility, and value than standard subscription tools provide:
Getting started takes less than 2 minutes:
chrome://extensions, enable Developer Mode, and load the unpacked folder.For a detailed step-by-step guide with screenshots, visit our Download & Installation Guide.
Your privacy is the foundation of My API Sider's design philosophy. The extension operates with a strict local-first architecture:
The only data that leaves your device is what you deliberately send to your chosen AI provider API — and that is governed by your provider's own privacy policy, not ours.
My API Sider represents a fundamentally different approach to AI tooling — one that puts users first. Rather than locking you into a single provider's walled garden or charging subscription fees on top of API costs, My API Sider gives you the freedom to use any AI model, any provider, with complete privacy and full cost transparency.
Whether you are a developer who needs a fast coding assistant, a marketer who wants versatile AI writing support, a researcher who needs document analysis capabilities, or simply someone who wants the best AI experience without paying multiple subscriptions, My API Sider is built for you.
