ChatGPT for PC - Use all LLM at one place!

Braina desktop software allows you to use large language models such as ChatGPT on your Windows PC with both speech to text and text to speech (TTS) features. Moreover, with the help of Braina, you can use ChatGPT or any other large language models like OpenAI's GPT-4 Omni, o1, o1 mini, Google's Gemini Pro, Anthropic's Claude 3.5 Sonnet/Haiku/Opus, Mistral Large etc. directly in any software or website. You can also run AI language models on your own computer locally using Braina.


Not only Braina provides a voice interface for LLM, it also has many advanced features like LLM Persistent Memory and Web access for LLM that allows you to use LLMs more robustly with great personalization and up to date information.



The most important advantage of using LLM in Braina is privacy and security of your data. For example, if you use ChatGPT in its website, your data will be stored and used for training (even if you subscribe to ChatGPT Pro). However, when you use ChatGPT in Braina, your data is not used for training and the chat history is stored on your own computer.

How to use ChatGPT Desktop app on PC?

ChatGPT is enabled by default in Braina. This feature is called Advanced AI Chat. You can confirm whether ChatGPT is enabled or not by going to Settings -> Search/AI engine tab. Make sure that "Medium", "High" or "Highest" is selected under the advanced AI chat engine preference.

To disable LLM use, you can select "Off" under the advanced AI chat engine preference option. When "Medium" or "High" option is selected, Braina will decide which user input should be handled by itself and which input should be answered by LLM. You can use Braina's in-built commands as well as custom commands when "Medium" or "High" preference is selected. However, this may sometimes cause problem if you only want to interact with ChatGPT exclusively. In this case, you can select "Highest (AI LLM Mode)" in preference options.

Advanced AI Chat preferences

You can also switch to “Highest” preference or "AI LLM Mode" directly in Braina's main window by turning on "AI LLM Mode" switch in the status bar. Advance AI LLM Mode


The "Highest" advanced AI chat engine preference will override Braina's in-built commands and even the custom commands created by you. Each and every input is only answered by the selected large language model and Braina won't perform any tasks when the "Highest" preference is enabled. Only the "cls" (to clear the screen) and open command (e.g. Open Notepad) works in "Highest" preference. Please note that the "Highest" preference is only applicable to the current session. If you restart Braina or your computer, the preference will get changed to "High" automatically.

Advanced AI context aware options

Braina provides various context aware options as follows:

  • No : Only current input is processed by LLM.
  • Previous Interaction: Previous interaction is processed along with the current input for context awareness. This is the default option.
  • Previous Input only: Only your input of previous interaction is processed along with the current input.
  • advanced AI context awareness options Braina
  • Past 3 interactions: Previous three interactions are processed along with the current input for context awareness.
  • Past 3 inputs and last reply: Previous three inputs are processed by the Advanced AI Chat engine i.e. LLM along with previous reply and the current input.
  • Maximum interactions: Maximum interactions are processed for the most context awareness. However, this will use more Advanced AI tokens.

You can use cls command to clear the screen along with the context

Note: Sensitive texts such as notes, reminders, alarms, custom commands list etc. are not sent for processing to advanced AI chat to maintain your privacy.


Web Search for Large Language Models

Web search features allows the Advanced AI Chat engines or LLM to incorporate the latest information and trends into their responses, ensuring that their answers are current and relevant. For example, a large language model with web access can provide up-to-date information on weather forecasts, upcoming movies, or new events, offering users real-time insights and accurate data. Additionally, web access empowers Braina to gather diverse perspectives and support its understanding of nuanced topics, resulting in more comprehensive and insightful communications.

To enable web access for LLM, go to Settings -> Search/AI Engine tab, turn on “Enable Web access for LLM” switch and click Ok.


Third Party Search Providers

Enabling this optional feature can enhance your search results, though it might add an extra 5 to 10 seconds to the search process.


Deep Search

Deep search feature searches the web in depth to find more context related to your query. This can be helpful for research.
If you are using a local LLM, please make sure that it has the context length set to 8192 tokens or more for the deep search to work properly.



Image / Multimodal support

Multimodal LLM support, including Braina Pinnacle, GPT-4 Omni, Gemini Pro, Claude 3.5 Sonnet etc. enables Braina to process and understand both text and visual data, significantly enhancing its ability to provide comprehensive responses and insights. Braina also supports local vision LLMs like Llama 3.2, Llava, MiniCPM-V etc.

Braina provides an easy way to add selections and desktop screenshots as attachments to multimodal LLMs. To attach a screenshot, click on the clip icon (on the left side of input field) and select "Add Selection screenshot" (Ctrl+H) or "Add Desktop Screenshot" (Ctrl+J). To take screenshot from other monitor screen, move your mouse pointer to that screen and press the keyboard shortcut (Ctrl+H or Ctrl+J) while the focus is still on Braina's window.

Chat with PDF and other files

  • Display whole reply at once: Whole reply is displayed only when complete response is generated by the AI engine.
  • Stream Words: Words are streamed in real time as the AI engine produces the response.
  • Stream Paragraphs: Paragraphs or lines are streamed as the AI engine produces the response.
