WriterPi vs Harpa AI
These two get compared a lot and they shouldn't be. Harpa is a browser automation platform that happens to include an AI sidebar. WriterPi is an AI sidebar that deliberately doesn't try to be a platform. Which one you want depends entirely on whether you'll build workflows.
The honest split
- Pick Harpa if you want to automate repeated browser work — scraping pages on a schedule, monitoring for changes, chaining multi-step commands across sites. It's a powerful tool and there's nothing in WriterPi that competes with that.
- Pick WriterPi if what you actually do is read things and write replies, and you want that to be fast, cheap and obvious. Plus games, reminders and screen time that Harpa doesn't have.
The learning curve question
Harpa's power comes with a genuine setup cost. Commands, workflows, page monitors — there's a model to learn before it earns its keep. People who invest that time get a lot back. People who don't tend to install it, use the chat sidebar, and never touch the rest.
If you suspect you're in that second group, you're paying a platform price for a sidebar. That's the entire case for something simpler.
The best tool isn't the one with the most features. It's the one whose features you actually use.

What WriterPi does instead of automation
One-click actions, proposed by the AI and applied by you: fill a form, scroll to a section, highlight a quote, open a link. It's automation-shaped but it's a single step you approve, not a workflow you configure. The deliberate limit is that nothing runs without you watching.
Then the three things Harpa doesn't have at all:
- Word games from the page — Word Hunt, quiz, Wordle and typing race built from the article you're on. Free on every plan.
- Reminders that arrive finished — the message is written now, delivered at 4pm ready to send.
- Honest screen time — counts only genuine attention, never leaves your device.
On permissions
Automation platforms generally need broader browser access, which is reasonable
given what they do — but it's worth reading the install prompt and knowing what
you agreed to. WriterPi avoids Chrome's tabs permission entirely, so
it never triggers the "read your browsing history" warning. Different tools, and
a genuinely different amount of access.

Can you use both?
Yes, and some people do — Harpa for scheduled monitoring, something lighter for everyday reading and replying. Two extensions both injecting into every page has a cost in memory and the occasional layout scuffle, so it's worth deciding whether you really use both sidebars or just one.
