Choose HARPA AI if…
HARPA's insight is that most useful automation happens on pages you are already looking at. It sits in Chrome, reads the current page, and can then extract a table, watch a URL for changes, or run a saved multi-step command against it. That makes it the rare AI extension that does real work rather than just summarising. It asks for patience in return: the command system is powerful but genuinely takes an afternoon to learn, and everything is tied to Chrome, so a Safari or Firefox habit rules it out.
- Reads and acts on the page you are already on
- Website monitoring and data extraction built in
- Large library of reusable saved commands

Most assistants hand back a plan; Manus goes and does it. Give it a research question and it opens a browser, reads sources, writes code if it needs to, and returns a finished document, all inside its own sandbox, while you do something else. That shift from advice to deliverable is the whole point, and when a task runs long it is genuinely the difference between an afternoon and a coffee break. The catch is the credit meter: complex runs burn through an allowance fast, and because you were not watching, you have to review the output properly before trusting it.
- Runs long multi-step tasks without supervision
- Works in its own sandbox with browser and code access
- Delivers finished files, not just text
