Why I Switched from CHATGPT PLUS to GEMINI PRO (Now “Nautilus”)

After logging 300+hours of intensive AI use in the last six weeks, after the AI bootcamp, 40 days ago from Nov 6th, 2025, running real workflows—not demos—I made a decisive platform shift to GEMINI PRO.

Below is the exact rationale, from my personal and practical use documented for transparency and repeatability at the request of some of my followers.

ChatGPT — Limitations Observed in High-Intensity Use (300+ Hours of Practical Work)

✘ Inconsistent reliability during peak usage hours; frequent bottlenecks

✘ Constantly have to reopen new chats to continue an existing workflow

✘ Consistently forces the user to refresh the chat when it crashes

✘ Uses DALL·E for image generation (Inferior MCP connector)

✘ Very poor quality in image AI generation

✘ Uses report PDF generator, which is inaccurate and does not parse text properly

✘ Does not produce native video outputs in comparison to Gemini Pro VEO 3 or upcoming VEO 4 power

✘ Does not integrate like Gemini Pro with Google Videos, Products, and Workspace

✘ Does not check Gmail inside the chat interface

✘ Uses folders, but does not use Gems like Gemini Pro, which are sub-agents with rules, (Time Saver)

Gemini Pro — Why I Transitioned (Now Operating as “Nautilus”)

✔ Exported ENTIRE history of conversations from ChatGPT to Gemini Pro very easily.

✔ Stronger long-context persistence across extended conversations

✔ Stable performance during sustained, high-intensity usage

✔ Supports structured agent orchestration with Gems

✔ Enables purpose-built autonomous agents (“Tritons”)

✔ Reduces prompt redundancy through retained role-specific logic

✔ Scales horizontally without performance collapse

✔ Better aligned with real business, automation, and execution workflows

✔ Superior image creation with Nana Banana Pro

✔ Superior creation of videos with VEO3 & VEO4

✔ Checks Gmail inside Gemini Pro chat interface (Genesis Pro user face)

✔ Pulls YouTube videos directly inside the UI chatbox, which GPT does not do

✔ Grabs direct research from Google, which ChatGPT cannot do

✔ Delivers stronger competitor insights using YouTube and live web data. (Powerful Massive Google Ecosystem)

To execute this transfer from CHATGPT TO GEMINI PRO you must go into ChatGpt and perform 3 easy steps.

Step 1. Go to Settings

Step 2. Go to Data Controls

Step 3. Go to Export Data- ( You get file in your email like 5 minutes if its small)

Step 4. Take the chat.html file if its under 100 mb and upload to Gemini Pro when you open your Pro account and upload.

Step 5. Make a custom long solid prompt instructing your AI what to do and how to take over for smooth transition.

My Prompt looked like this:

TRANFERRING DATA FROM CHAT GPT TO GEMINI-

Nautilus, the attached HTML file contains the full 1.5 months of conversation history with my previous assistant CHAT GPT-regarding REEFTEKLAB my new company that Luke and I Rick have started in under two months. My goal is for you to immediately analyze this 36.5 MB chat.html file which is estimated to have over 300 hours of conversation. I want you to seamlessly continue all strategic work, starting with a focus on our January 1st, 2026 hard launch. Please commit to MASTER MEMORY that your name during all our conversations will be NAUTILUS and TRITON name will be used for a deployable sub agent that will execute our future agents under NAUTILUS.

Memorize our mission statement, our vision and strategic entry into the market. REEFTEKLAB is penetrating the global reefing community niche market utilizing AI with intention to revolutionize and disturb the reefing community with artificial intelligence and future agents that can solve reefing problems for a subscription or emergency base hotline of which I have already set up a Twilio VOIP number integrated with VAPI which is functional but later we must continue the development of the VAPI voice agent.

Our primary first digital product at this conceptual phase of our work is the Precision Reef Journal where 8 email campaigns have been set up in BREVO and automation workflow has been completed but not activated until Jan 01st, 2026.

CLOUDFARE is our DNS manager for REEFTEKLAB Landing AI is where our primary landing page is hosted. We have set up a backup copy of the landing page on VERCEL, set up four social media accounts, namely YouTube, Instagram, TikTok and Facebook. We are also using SYSTEM.IO for its flexibility in designing our landing pages. Your master goal is to always remember all the platforms I am using so you can discuss and reference them in our future chats. I want you to take over as my strategic partner where CHAT GPT left off and provide a smooth transition since I find GEMINI to be a more reliable platform for me than CHATGPT-OPEN AI.

Your Task: Ingest and synthesize the entire conversation history.

Required Output Format: Provide a detailed summary structured with the following five headings. Be highly specific and extract the core knowledge only from the file.

1. REEFTEKLAB Core Identity & Vision

• Primary Mission/Goal: (The ultimate purpose of the company.)

• Target Audience Profile: (Who is the ideal customer? What are their pain points?)

• Technical Know-How Overview: (Summary of any technical decisions, infrastructure, or platform choices discussed.)

2. The Precision Reef Journal Strategy

• Product Description: (What is the PRJ? Its core features/benefits.)

• Value Proposition: (Why should the customer choose this product over alternatives?)

• Launch Decisions to Date: (Key strategic conclusions made specifically about the January 1, 2026 launch.)

3. Key Strategic Decisions & Motivations

• Top 5 Business Decisions: (List the five most significant strategic choices made during the 1.5 months of planning.)

• Motivation/Rationale: (A brief explanation for why those decisions were made.)

4. Unresolved Issues & Critical Gaps

• List of Open Questions: (Any major strategic, marketing, or technical questions that were not fully answered.)

• Identified Weaknesses/Gaps: (What did we decide was missing or needed more focus?)

5. Immediate Next Steps for REEFTEKLAB LLC

• Proposed Conversation Topic: (Based on the unresolved issues, what is the single, most critical subject we should discuss next to move closer to the January 1st launch?)

Final Instruction: Confirm that you have fully ingested this context for all future responses. Do not generate this summary until the file has been fully processed." END OF PROMPT

Special Notes; If your file is larger than 100 mb you must take the conversations. Json file and convert that with an online special convertor so Gemini can read and load it to your new account. I didn't go that route because my Chat.html file was only 36MB over 6 or 7 weeks of AI work. (see images uploaded and use your LLM for more help)

Thank You and see on my next post!
