A HARPA AI alternative you set up in plain words
Updated
Choose BrowseWiz if you'd rather describe a recurring job in plain words than build it as a command. It fills a Google Sheet, refreshes it on a schedule and alerts you when a page changes the way you described. Stay with HARPA for checks every 15 seconds, email or webhook alerts, a lifetime plan or a lower price.
Add to Chrome – it's freeTrack three competitors' changelogs without building a command
In HARPA, a weekly job like this means scheduling an AI command, and its guide says scheduling "requires a basic understanding of Custom Commands & Parameters" Source 1. In BrowseWiz, you describe the job, approve the plan and say when to repeat it:
Open the changelogs at tallyhq.example/changelog, bramble.example/releases and quillstack.example/news. Put each entry from the past week in a new "Competitor releases" sheet: date, what shipped, competitor, type (feature, fix or pricing) and a link to the entry.
Approve the plan, then grant tab access and sign in to Google once when asked. The first run creates the sheet in your Google Drive while you watch. Then reply "Repeat this every Friday at 9:00 and add only entries that aren't in the sheet yet" and approve the new plan.
The sheet after two Friday runs
The first run, in chat on Friday, Sep 25, added three rows. The next Friday's scheduled run added only the two entries posted since, including Bramble's price rise. Each link opens the entry it came from.
| Date | What shipped | Competitor | Type | Link |
|---|---|---|---|---|
| Sep 22 | Shared dashboards | Tally | Feature | tallyhq.example/changelog/118 |
| Sep 23 | Duplicate Gmail contacts fixed | Bramble CRM | Fix | bramble.example/releases/4.12 |
| Sep 24 | Bulk export to CSV | Quillstack | Feature | quillstack.example/news/csv |
| Sep 29 | Starter plan from $15 to $19 | Bramble CRM | Pricing | bramble.example/releases/4.13 |
| Oct 1 | Slack alerts for scheduled reports | Tally | Feature | tallyhq.example/changelog/121 |

HARPA runs the steps you build. BrowseWiz works out the steps.
A custom HARPA command is a chain of steps, such as NAVIGATE to a URL, CLICK an element and EXTRACT its content Source 2. Steps that click or extract find their element with a selector you grab from the page or write in YAML Source 9. A HARPA monitor is configured too: you set the page, a trigger and the actions it fires Source 4.
In BrowseWiz, the description is the setup. The agent opens each page, works out where the data is and writes the rows. You watch the first run in chat, then approve a schedule. After that, scheduled runs approve their own clicks, and a safety check refuses any step that would send, pay, delete or submit something you didn't ask for. A monitor needs only a sentence, and a model decides whether a change matches it.
The trade-off is exactness. A HARPA command repeats the same steps on every run, and its trigger fires on a precise rule, as often as every 15 seconds. The BrowseWiz agent may take a different path from one run to the next, and a model can misjudge a change. If the job must repeat identical steps, build it in HARPA.
How it works
Name the pages and the columns
List the changelogs, release notes or pricing pages, and say what each row should hold. There are no steps, selectors or parameters to set.
Approve the plan, then the schedule
BrowseWiz shows its plan before it browses. After you grant tab access and sign in to Google once, the first run creates the sheet while you watch. Ask it to repeat every Friday at 9:00 and approve the new plan. That saves a scheduled task and runs nothing yet. Free allows up to once a day; Pro and Max, up to hourly.
Let each run add the new rows
Each scheduled run opens the pages in the BrowseWiz Tabs group in your signed-in Chrome, adds only the new entries to the sheet it created and alerts you when it finishes. See how the browser agent works.
Which one fits
Choose HARPA AI if…
- You need checks faster than every 5 minutes, down to 15 seconds.
- You want email or webhook alerts, or runs started from Zapier, Make.com, n8n or an API.
- You want exact steps that repeat on every run.
- You use it mostly as a sidebar to chat with pages, summarize videos and write, with 100+ ready-made commands Source 10.
- Price matters most: $12 or $19 a month, or $240 once.
- You want a choice of models, your own API keys or free web sessions, or Brave or Opera.
Choose BrowseWiz if…
- You'd rather describe a recurring job than build a command and pick elements.
- You want an alert when a change matches what you wrote, not a fixed trigger.
- You want the combination: plain-English requests in your signed-in Chrome, rows in Google Sheets, scheduled runs and monitors while Chrome is open, and a plan you approve before it acts.
- You want a free plan that includes a scheduled task and a monitor.
Where BrowseWiz falls short
- Slower checks. Monitors check about every 5 minutes, with no faster setting.
- Chrome must be open. Scheduled runs and monitors stop while Chrome is closed or your computer is off. For checks around the clock, use a cloud monitor.
- Signed out means no data. If a site signs you out, scheduled runs land on its sign-in page until you sign in again in Chrome.
- No email or webhook alerts. Alerts arrive in the side panel, on the page or as a system notification.
- Its own sheets only. BrowseWiz creates the sheet in your Google Drive and keeps writing to it, but it can't edit a spreadsheet you already have.
- Not scripted. Runs can differ slightly. When the output must be identical every time, a step-by-step command is safer.
- One built-in model for automation. Schedules and monitors always use BrowseWiz Chat. Your own key or an OpenAI-compatible model works in chat only.
- Not for volume. Thousands of URLs, proxies and captchas need a dedicated scraper.
What it costs
HARPA's paid plans cost less: $12 a month for Everyone, $19 for Pros, or $240 once for Life Source 3. BrowseWiz Free includes a scheduled task, while HARPA's plan grid lists scheduling on Pros and Life only.

One run, in each tool's unit. HARPA's FAQ puts 1 Megatoken at roughly 100 command runs on its Cloud models; your own key and web sessions don't use them Source 3. So Pros' 15 Megatokens a month come to about 1,500 runs (15 × 100). In BrowseWiz, one reply that reads a 30,000-character page costs about 7,500 × 5 + 500 × 30 ≈ 52,500 credits, and an agent run costs more because it re-sends the chat at each step. A monitor check that finds no change makes no model call. Prices exclude VAT. See how credits are counted.
Questions
HARPA is an AI sidebar and automation toolkit: you chat with a choice of models, run 100+ ready-made commands Source 10, and build your own commands and monitors step by step. BrowseWiz is an agent in Chrome built around one job: you describe the data in plain words, and it fills a Google Sheet, refreshes it on a schedule and alerts you when a page changes the way you described.
Yes, within limits. HARPA's free DEMO plan includes 10 web-session messages a day, up to 100 AI command runs in total, and web monitors Source 3. Its plan grid lists scheduled commands on Pros, $19 a month, and the $240 lifetime plan only. BrowseWiz Free includes one scheduled task that runs up to once a day, one monitor and 10M credits a month.
Yes. Nanobrowser is a free, open-source Chrome extension for AI web automation, under the Apache 2.0 license. You bring your own API key from OpenAI, Anthropic, Gemini, Ollama or another provider, and pay only for what you use Source 11. BrowseWiz isn't open source, but its free plan needs no API key and includes a scheduled task, a monitor and 10M credits a month.
Yes. HARPA's version 14.0 changelog lists reading, editing, clearing and inserting rows in Google Sheets from AI Source 5, and its monitors can send data to Google Sheets through Make.com Source 4. BrowseWiz creates the spreadsheet in your Google Drive and keeps writing to it on a schedule. It can't edit a sheet you already have.
As often as you choose, from every 15 seconds to once a month; by default, every 3 hours. HARPA warns that frequent checks can log you out of some sites or bring up a captcha Source 4. BrowseWiz checks each monitor about every 5 minutes, with no faster setting, so for alerts within seconds HARPA is the better tool.
Yes, with both. HARPA connects to your own API keys, to OpenRouter, Straico or Azure, and to free web sessions of ChatGPT, Claude and Gemini Source 3. BrowseWiz takes your own OpenAI key or any OpenAI-compatible model, but only in chat. Scheduled tasks and monitors always use its built-in model, BrowseWiz Chat. See how custom models work.
