Sidekick Browser Alternatives: Current Status and Browser Workflows

As checked on 5 October 2026, the former Sidekick website redirects to Perplexity Comet. A Sidekick alternative article must distinguish the historical work browser from the product presented at its old address today.

TL;DR

Comet is a complete AI browser. SuperCommands is an extension for local saved work and user-triggered commands. Neither an old Sidekick plan table nor an extension feature list establishes parity with Comet.

SuperCommands vs Sidekick and Comet

Comet's current product page presents a browser with an integrated assistant and browser-task capabilities. The redirect is evidence of the current destination, not a guarantee about an older Sidekick installation already on your computer.

Requirement	SuperCommands	Browser-level alternative
Reopen named project URLs	Local Workspace/Link	Browser collections or contexts
Keep decision context	Notes, Todos, and Web Clips	Product-specific saved material
Separate website accounts	Existing browser profiles required	Evaluate actual profile/container behavior
AI interaction	User-triggered supported provider handoff	Integrated assistant where provided
Recurring unattended web task	Not established	Verify product, plan, and execution behavior

Feature Comparison

For SuperCommands, create a Workspace from the useful project URLs, select launch settings, and save. Retrieve it from New Tab search, configured Alt+S on supported pages, or c, Space, and your query in the address bar. Assign an optional Text Command for frequently used work.

Notes and Links retain local project context. Web Clips can retain extracted article text, screenshots, or bounded element captures. ZIP and optional Drive backups protect this data, but are not a shared cloud library or live cross-device sync.

Supported AI handoff actions are user-started and provider compatibility needs testing. A Todo due-time reminder does not replay an arbitrary browser workflow unattended. SuperCommands does not establish Comet-equivalent browser-agent execution.

Use Cases

For a vendor review, save the vendor pages in a Workspace and record your comparison in a Note. Manually invoke a supported page-context action if needed. For a browser agent that continues research and acts on pages later, evaluate Comet's current documentation, account requirements, and task availability rather than assume an extension reminder performs that work.

If the requirement is specifically an open-source browser, evaluate a full browser project such as Firefox or Zen. That is a different change from installing an extension in Chrome.

Pricing Comparison

Do not use historical Sidekick plan amounts as current Comet pricing. Check the current Comet offering for the assistant/task feature you need. SuperCommands public license and unlimited/free-forever terms are not confirmed in this comparison.

Key Takeaways

SuperCommands is partly suitable for saved browser organization and manual actions, but not suitable as a complete AI browser, identity-container platform, or unattended agent replacement.
