What HARPA stands for?
HARPA stands for High Availability Robotic Process Automation. HARPA is designed to bridge the gap between AI and Automation and serve as your virtual assistant and a digital workforce for your business.
Do I need to have an OpenAI account?
Generative AI features require connection to AI service providers. You can use HARPA with ChatGPT account, OpenAI API key, ClaudeAI, Google Gemini, OpenRouter and API keys.
You can also connect to our CloudGPT on S plan.
How to create ChatGPT account?
Step 1: Navigate to the ChatGPT login page. Click Sign Up button. ChatGPT offers three options for new user registration:
- With email address.
- With your Google account. Click the Continue with Google account option, and enter your Google account password to complete the process.
- With your Microsoft account. Click the Continue with Microsoft account button, enter your password, and complete the sign-up process.

How to get access to GPT-4?
HARPA CloudGPT supports GPT-4 model. Please upgrade to S plan to get access to GPT-4.
Alternatively, GPT-4 comes with ChatGPT Plus. It is limited by OpenAI to 50 requests per 3 hours. GPT-4 is also available for OpenAI API accounts.
To upgrade to ChatGPT Plus:
- Log in to your OpenAI account.
- Click "Upgrade to Plus" in the left menu.
- Select the ChatGPT Plus upgrade plan.
- Enter your bank details and set up a recurring payment of $20/month.

Alternatively, type -3 in chat and press Enter to switch model to GPT-3, -4 to switch to GPT-4, -c to switch to ClaudeAI, etc.
How does HARPA ensure privacy and data security?
HARPA is privacy-centered. It runs on your computer, does not send or store website data on remote servers, only performs the tasks you have asked it to. We do not show ads or sell your data.
GPT prompts you enter to HARPA are transparently sent to OpenAI, Google or ClaudeAI servers for processing and not stored on our servers.
Why HARPA does not open on a web page?
HARPA does not work with Google Sheets yet. Some domains e.g. Discord may require you to disable fingerprint protection on Brave and Edge. Click HARPA icon in the browser toolbar, instead of pressing Alt+A. If the HARPA popup does not appear:
- Right click HARPA icon in the browser toolbar. Make sure "This Can Read and Change Site Data" option is set to "On all sites".
- uBlock may prevent HARPA from loading on some websites. Try turning it off for the web page.
- If you are on Chrome:
- Navigate to chrome://settings/content/popups
- Add your domain to Allow list.
- If you are on Brave:
- Navigate to brave://settings/shields
- Either deactivate “Prevent sites from fingerprinting me based on my language preferences” option, or deactivate Brave Shields for your domain, e.g. Discord.
- If you are on Edge:
- Navigate to edge://settings/content/ads
- Either deactivate "Intrusive Ads" block or add your domain to Allow list.
If nothing helps, navigate to chrome://extensions, disable HARPA, quit and restart your browser, and turn HARPA back in.
Why do I get CRX_FILE_NOT_READABLE error?
This error may occur if:
- You downloaded a CRX file and installing it manually. CRX files downloaded online may be broken or insecure. We recommend installing HARPA from the official Chrome Web Store.
- You are using NordVPN with the "THREAT PROTECT" is ON. Turn it OFF while installing HARPA extension.
Why HARPA chats are not showing up in ChatGPT?
You can see 🧬 chats in chatgpt.com if you're on a Browser Session connection. If you don’t want your dialogues to be cleared automatically whenever a tab is closed, you can change this in the App Settings.
Why HARPA says there is no video transcript?
If a YouTube video is fresh or has a low number of views, it may not have a transcript available. If you are using uBlock Origin, turn it off while running HARPA or add a rule to allow XHR requests on YouTube.
Can HARPA generate blog outlines and articles?
Yes, HARPA has an extensive library of copywriting prompts, can generate and refine short and long articles in 18 writing styles and can mimic yours.
How to turn off the bar that pops up when I select text?
Please click the settings (”gear”) button in the app and uncheck the box next to “Show floating quick-access bar”.
Which API connection is better than Browser Session?
HARPA S plan comes with CloudGPT, which is the most reliable, fastest and non country restricted GPT connection. You can also use CloudGPT or OpenAI keys with HARPA with an additional setup.
There are Pros and Cons to using OpenAI API keys over Browser Session:
- Browser Session connection is free, Browser Session Plus is $20 / month and OpenAI API Key connection is paid per use based on the number of tokens (request volume).
- GPT-4 access is unlimited on OpenAI API key connection. Browser Session is limited to 25 requests per 3 hours. OpenAI API accounts may have access to GPT models with larger context windows, e.g. gpt-8k and gpt-32k.
- The OpenAI API key connection is reliable, never disconnects or logs you out.
What search engine supported?
HARPA provides AI search assistance for Google, Google Scholar, Baidu, Bing, DuckDuckGo, Brave, Yahoo, Naver, Yandex, Kagi, Searx.
Can I reuse one AI dialogue across multiple browser tabs?
Yes, this feature is available on HARPA S plan. Please note the dialogue content is not stored on our servers and is not synched between your devices.
What is a Prompt and AI Command?
A prompt is a message (instruction) your send to Large Language Model (LLM) such as OpenAI GPT-3.5. AI Command is an automation recipe which may or may not include steps that prompt LLMs.
Think of AI Commands as a sequence of steps, e.g. “Navigate to web page”, “Click Messages button”, “Extract messages”, “Run through GPT to find important messages”, “Send as Email”.
HARPA comes with over 100+ preconfigured commands and you can create yourself to automate your workflow.
What are Prompt Parameters?
HARPA makes it possible to customise your prompts with predefined parameters, such as:
- {{page}} to reference page content.
- {{transcript}} to extract YouTube video transcript.
- {{selection}} to get text selected on page.
- {{gpt}} to reference the last GPT answer and chain your requests.
You can also create custom parameters in your commands to store data or options. Custom parameters are usually named {{p1}}, {{p2}}… You can also set up global parameters such as {{g.tone}} and reuse them in your prompts e.g. to write customised emails.
How chunking works?
Large Language Models have a limited token window, e.g. 8192 tokens on ChatGPT 3.5. It is often impractical or impossible to fit large documents, web pages, and video transcripts into a single GPT request.
Chunking is a technique that divides content into smaller parts, also called chunks, to ensure that each part, including the prompt, fits within the GPT token limit. These chunks are then injected into prompts as {{chunk}} parameters and processed by GPT one by one.
Chunking does not possess inherent memory. Therefore, if you require context to be maintained across chunks, it must be incorporated within the prompt.
How to change AI response language?
Most HARPA AI commands send a {{language}} parameter with prompt. You can set the language for commands output in the app settings. You can also send {{language}} parameter in chat along with your prompts to instruct AI to reply in a given language.
How do I change UI language?
HARPA UI is currently available in English only. We will internationalize and translate the user interface to Spanish, French, German and other languages once all the major features are implemented.
Does HARPA have a CloudAI API?
Yes. HARPA S plan comes with CloudAI API, and provides reliable access to OpenAI and ClaudeAI models.
Does HARPA have a Server API?
This is a planned feature. You can follow product updates in our Discord and also vote for the features you’d like to see implemented first.
Do you offer Firefox version?
Not at the moment. The Firefox version as well as UI translation are planned after all the major features are implemented.
