In-depth review: Askman Chrome Extension
Askman is a Chrome extension that positions itself as a lightweight, open-source tool for users who want to bring customizable AI prompts directly into their browsing workflow. Rather than offering a polished, all-in-one assistant, Askman focuses on flexibility: it supports OpenAI-compatible protocol formats, allowing users to connect their own API endpoints or use the free trial API provided by SiliconFlow. The core differentiator is the ability to create custom prompts that include page elements as variables—such as selected text, the page URL, or other metadata—enabling queries that are contextually aware of the current page. This makes Askman particularly suited for researchers who need to extract structured data from web pages without leaving the browser, students who want to quickly summarize articles or generate study questions, and developers who appreciate the transparency and customizability of an open-source codebase. However, the extension requires manual prompt setup, which means users must invest time in crafting effective prompts. The free trial API may also have usage limits, and compatibility is restricted to OpenAI-compatible protocols, so those reliant on other providers will need to configure their own endpoints. For a practical buyer, Askman is best viewed as a modular building block rather than a turnkey solution—it rewards users who are willing to tinker and tailor the tool to their specific needs. The open-source nature also means the community can extend functionality, but out-of-the-box polish is limited. Ultimately, Askman fits best in the hands of information workers who value control over convenience and are comfortable with a degree of manual configuration.
Who it's built for
Researchers
Why it fits
Researchers often need to extract structured data from multiple web pages. Askman's custom prompts with page element variables allow them to pull specific information like dates, names, or statistics without leaving the browser.
Best value
Saves time by automating data extraction from pages during literature reviews or competitive analysis.
Caution
Requires manual setup of prompts for each type of data needed; may not handle complex extraction logic.
Students
Why it fits
Students can quickly summarize articles or generate study questions from online content, making research and revision more efficient.
Best value
On-the-fly summarization and question generation help with comprehension and exam preparation.
Caution
Free trial API may have usage limits; summaries depend on the quality of the underlying AI model.
Developers
Why it fits
Developers can customize the extension to suit their workflows or contribute to its open-source codebase, adding features or fixing bugs.
Best value
Full access to source code allows tailoring the tool for specific use cases or integrating with other APIs.
Caution
Requires familiarity with Chrome extension development and the OpenAI protocol; not a plug-and-play solution.
Key features
OpenAI-Compatible Protocol Support
Askman works with any API that follows OpenAI's protocol format, allowing users to connect their preferred AI backend.
Benefit
Flexibility to choose from various AI models or services that support OpenAI compatibility, not locked into a single provider.
Limitation
Only supports OpenAI-compatible protocols; other API formats (e.g., Anthropic, Cohere) are not directly supported.
Custom Prompt Creation with Page Elements
Users can create prompts that include variables like selected text, page URL, or other elements, enabling dynamic queries based on current page content.
Benefit
Highly tailored interactions: e.g., 'Summarize this text: {{selected_text}}' or 'List all dates on this page: {{page_text}}'.
Limitation
Requires manual setup of each prompt; no built-in prompt library or templates provided.
Open-Source and Community Contributions
The project is open source on GitHub, inviting developers to inspect, modify, and contribute to the codebase.
Benefit
Transparency, security auditability, and the ability to add custom features or fix issues independently.
Limitation
Community support may be limited; no official customer support team.
Free Trial API via SiliconFlow
SiliconFlow provides a free trial API that works with Askman out of the box, allowing users to test the extension without upfront cost.
Benefit
Zero-cost entry to evaluate the extension's functionality and prompt customization.
Limitation
Free trial likely has rate limits, usage caps, or limited model access; not suitable for heavy production use.
Real-world use cases
Summarizing Articles
ResearchersScenario
A researcher reading a long online article needs a quick summary to decide if it's relevant.
Solution
Select the article text, activate Askman with a custom prompt like 'Summarize this in 3 bullet points: {{selected_text}}'.
Outcome
Saves time by getting concise summaries without leaving the page or copying text elsewhere.
Generating Questions from Content
StudentsScenario
A student studying from a web page wants to test their understanding.
Solution
Use a prompt such as 'Generate 5 study questions based on this content: {{page_text}}'.
Outcome
Creates immediate practice questions, enhancing active learning and retention.
Extracting Key Information
Content creatorsScenario
A content creator needs to pull all dates and names from a news article for a timeline.
Solution
Set up a prompt like 'Extract all dates and names from this text: {{selected_text}}'.
Outcome
Automates data extraction, reducing manual effort and error.
Pros & cons

Frequently asked questions
What protocol formats does Askman support?Workflow
Askman currently supports OpenAI-compatible protocol formats. This means it works with any API that follows the same request/response structure as OpenAI's API, including many open-source models hosted on compatible platforms.
Is there a cost to use Askman?Pricing
Askman itself is free and open source. However, to use its AI features, you need an API key from a provider. It offers a free trial API from SiliconFlow, but this may have usage limits. For extended use, you would need to obtain your own API key from a compatible provider, which may involve costs.
Can I contribute to the Askman project?General
Yes, Askman is open source and welcomes contributions. You can find the project on GitHub at https://github.com/askman-dev/askman-chrome-extension. Contributions can include bug fixes, new features, documentation improvements, and more.
How do I set up custom prompts with page elements?Workflow
After installing the extension, open its options page. There you can create new prompts using variables like {{selected_text}}, {{page_url}}, or {{page_text}}. For example, a prompt could be 'Summarize: {{selected_text}}'. Once saved, you can trigger the prompt from the extension's popup or context menu.
What are the limitations of the free trial API?Limitations
The free trial API provided by SiliconFlow likely has rate limits (e.g., requests per minute), a total usage cap, or access only to certain models. It is intended for testing and evaluation. For production or heavy use, you will need to obtain a paid API key from a compatible provider.
