Is SmarterBook Discontinued? There Are Two Different Products
The original SmarterBook Chrome extension created by Micah Lindley is discontinued and no longer functional, according to its public Chrome Web Store listing, archived GitHub repository, and developer shutdown notice. However, a separate current commercial product called SmarterBook Extension also exists. The shared name is why searches produce apparently conflicting answers.
This distinction was checked on October 21, 2026. Product status can change, so use the exact links and publisher information rather than relying on the name alone.
AutoGraw is independent and is not affiliated with either SmarterBook product or McGraw Hill.
The original SmarterBook by Micah Lindley
The original project appears in the Chrome Web Store under extension ID jikphdlhfedfoblcfdjaibhaanofgihd. That listing identifies version 1.4.0 and states that the extension has been discontinued and is not functional.
Its GitHub repository is archived and read-only. Archived status means the repository remains available as a historical reference, but ordinary development and issue activity have been closed.
The developer's SmarterBook shutdown notice says the functionality was removed after a cease-and-desist letter. That explanation concerns the original project and should not automatically be applied to another product that later used the same name.
What the original extension did
The old store and repository materials describe lightweight SmartBook convenience features. Public information includes quick search and copy controls and a Ctrl + Enter submission shortcut. It was not the same account-based commercial product now promoted at smarterbookextension.com.
If an old tutorial tells you to install that store listing, clone the archived repository, or expect version 1.4.0 to function today, the instructions are outdated. An archived codebase also may not match current McGraw Hill page structures or browser requirements.
The current commercial SmarterBook Extension
The current product presents itself at smarterbookextension.com and through a Whop storefront. Its public materials describe a broader browser tool with account access, auto-solving, hints, explanations, progress information, and support for multiple learning platforms.
That product should be evaluated using its current site, terms, privacy information, support route, and checkout. The discontinued status of the original extension does not prove that the current commercial product is discontinued, affiliated with the original developer, or affected by the same history.
How to tell which SmarterBook you found
Check four identifiers:
- Publisher or developer name. The original project is associated with Micah Lindley.
- Extension ID or repository. The original Chrome Web Store ID and archived GitHub repository are listed above.
- Domain. The current commercial product uses smarterbookextension.com and a Whop listing.
- Version and instructions. A guide centered on version 1.4.0, the old store page, or the archived repository is discussing the original project.
Do not install a file only because its name says SmarterBook. Verify the publisher, permissions, update source, privacy policy, and official support path.
Why old extensions stop working
Browser extensions that modify third-party courseware depend on page structure, browser APIs, and permission rules. A discontinued build can fail even when installation still appears possible. The target website may rename elements, change navigation, load content differently, or add new security policies. Chrome can also change extension requirements.
That is why “the file installed successfully” is not the same as “the product is maintained and compatible.” Look for a current release date, active official documentation, an update channel, and support that can address new page layouts.
Should you install the archived original?
An archived repository can be useful for learning how an older project worked, but it should not be presented as a maintained solution. A user who installs old code accepts the risk that it is incompatible, lacks current security maintenance, or conflicts with modern browser rules.
Never install repackaged builds from unofficial download sites. An extension or userscript can access the pages covered by its permissions, so the distribution source matters.
Current alternatives to evaluate
The current commercial SmarterBook Extension is one product to evaluate if its advertised broader platform coverage, hints, explanations, or analytics match your needs.
AutoGraw is another option for supported McGraw Hill workflows. It is a licensed Tampermonkey userscript with separate answer, submit, advance, and fallback controls; saved-answer tools; assignment utilities; a status HUD; and menu customization. It supports specific SmartBook and EZTO formats rather than claiming universal activity coverage.
Read the evidence-based AutoGraw and current SmarterBook comparison for the differences. Neither product should be treated as guaranteed accurate or automatically permitted in every course.
What to verify before choosing any replacement
- Is the official download actively maintained?
- Which browser and device are supported?
- Which exact McGraw Hill environment is supported?
- Does the product require an account, key, or subscription?
- What permissions does it request?
- What does its privacy policy say about assignment content and identifiers?
- How are updates delivered?
- Is there a current support channel?
- Are limitations described clearly?
- Does your institution allow the tool for the intended activity?
A transparent limitation is more useful than a promise that a product works everywhere.
