GeminiWe ship Gemini for real clients, not just in theory.
Most Gemini trainings are recorded tutorials made by people who opened the tool the night before. At Hack'celeration it's the opposite: writing prompts that hold up, tapping the multimodal, plugging Gemini into Google Workspace, building Gems and calling the API, that's our daily agency work. We ship Gemini workflows for clients every week. Everything we teach you, we practice on shipped projects. We know the traps (the prompt that works one time in two, the badly anchored Gem that answers off-topic) because we've already solved them.
- We ship Gemini workflows for clients every week, not just in theory
- 1-on-1 format: the trainer adapts to your level, beginner or seasoned dev
- We tell you when Gemini isn't the right call (sometimes ChatGPT or Claude fits your case better)
- We start from your real prompts and your real Workspace, not a dummy example
The Gemini training rests on four concrete pillars.
A badly used Gemini means prompts that disappoint, Workspace features you ignore, and multimodal potential never tapped. Most of the trouble comes from the method, not the tool. We pick up your real account and work through the four pillars together.
- Prompting and multimodal
Prompts that work, with multimodal on top
Prompt engineering isn't about magic formulas. We teach you the structure that gets the right result: role, context, task, format, constraints. And we tap what sets Gemini apart: native multimodal. You hand it an image, a 200-page PDF or a video, and it answers on it. We frame your real prompts so you stop firing off ten retries to get one usable output.
See the prompting - Google Workspace
Gemini inside Gmail, Docs and Sheets
This is the edge no one else has: Gemini is woven into Google Workspace. We teach you to use it right where you already work. Draft and summarize in Gmail, write and rephrase in Docs, build formulas and organize data in Sheets. No more copy-paste across ten tabs. You stay in your tool and the AI comes to you, with the context of your Drive files.
See the Workspace setup - Gems and Deep Research
Your custom assistants, plus research in depth
Gems are Gemini's custom assistants, the equivalent of custom GPTs. We build one on your repetitive tasks, anchored to your Docs and Sheets through Drive for answers that match your context. And we walk through Deep Research: Gemini plans, runs dozens of searches, reads the results and hands you a sourced report, pulling from your Gmail and Drive too.
See the Gems - The Gemini API
Plug Gemini into your product, API and automation
If you want to go beyond the chat, we build with the Gemini API: request structure, token and cost handling, function calling so Gemini calls your functions, and automating Workspace tasks through Apps Script. We also wire it into Make or n8n. You leave with an API call that runs from your code or your no-code automation, not just a demo.

- A diagnosis of your use cases and your current prompts
- The first actions to take, in priority order
- The right 1-on-1 format for your level and goals
- An honest take: Gemini or ChatGPT for your case
Your Gemini program, step by step.
Five steps, no skipping. Each one on your real account, with a clear deliverable. From the first session we frame your use cases and write your first prompts. By the end, you use Gemini without us.
- Step 1 · Use-case audit
We open your real Gemini account and frame your actual cases
First session, we share your screen and look at your usage together. What do you do with Gemini today (or what would you like to)? Writing, doc analysis, research, spreadsheets? We list your recurring tasks and the ones eating your time. We spot which ones Gemini handles well and which it doesn't. You leave with a clear diagnosis and the list of work, in priority order. No theory, your real account.
- Step 2 · Prompts on your real tasks
We write prompts that get the right result
We go after the concrete part: your prompts. We set the structure (role, context, task, format, constraints), and we tap Gemini's multimodal on your real files: an image to describe, a PDF to summarize, a video to analyze. We pick up your failed prompts, figure out why they went off the rails, and turn them into reusable templates. By the end, you have a library of prompts that work on your day-to-day tasks.
- Step 3 · Workspace and Gems
We plug Gemini into Gmail, Docs, Sheets and your Gems
We tap what makes Gemini strong: the Google Workspace integration. We teach you to use it inside Gmail, Docs and Sheets, right where you already work, no copy-paste. Then we build a Gem on your repetitive tasks, anchored to your Drive documents for answers that match your context. We also walk through Deep Research for your deeper topics. You practice on your own files, not a dummy example.
- Step 4 · API and automation if relevant
We plug Gemini into your product or your automation
If your need goes beyond the chat, we move to the Gemini API. We structure requests, token and cost handling, and turn on function calling so Gemini calls your functions. We automate Workspace tasks through Apps Script and wire it into Make or n8n. You leave with an API call running on your case. This step is optional depending on your need, we don't force it if the chat is enough for you.
- Step 5 · Autonomy
You use Gemini without us
The number one goal: you become autonomous. By the end of the program, you know how to write a prompt that works, tap the multimodal, use Gemini inside your Workspace, build a Gem and call the API if you need it. You no longer need an agency to get value from Gemini day to day. And if you want to delegate later, we also run a Gemini agency, but that's not the point here.
Why train 1-on-1 with us.
- 300+Pros already trained on AI
More than 300 people have gone through our trainings across France and Europe. Teams, devs, small-business founders. Not vanity numbers: people who now use Gemini every day to write, analyze and automate, instead of copy-pasting prompts found at random.
- 4.7/5Rating across 334 verified reviews
Average rating of 4.7 out of 5, across 334 reviews. We won't promise the AI does everything on its own: you have to practice on your real cases. But the 1-on-1 format makes the difference between a prompt that disappoints and one that outputs exactly what you want.
- 1:1A dedicated expert, not a class of 100
You're not a number in a webinar. A trainer opens your real Gemini account, looks at your prompts and your Workspace, and works through your actual cases. We schedule sessions around your availability, replays included.

The questions we get the most.
What is a 1-on-1 Gemini training?
An individual program with a Gemini expert, not a class of 100 people. We open your real account, look at your prompts and your Workspace, and work through your actual cases: prompt engineering, multimodal, Gmail and Docs integration, Gems, API. You ask your questions live, the trainer adapts the pace to your level. We schedule sessions around your availability, and you leave with concrete actions every time. That's what makes the difference between watching a tutorial and actually knowing how to use Gemini in your work.How much does the Gemini training cost?
There is no single price. We connect you with a trainer certified by Hack'celeration, matched to your need and your level. It varies from one trainer to another, based on their profile and the format that fits your project.Gemini or ChatGPT: which one to pick?
It depends on your usage. Gemini often wins if you live in Google Workspace: it's natively built into Gmail, Docs and Sheets, and its multimodal swallows images, long PDFs and video without blinking. ChatGPT keeps an edge on the maturity of its GPT ecosystem and some third-party integrations. If your day-to-day is Gmail, Drive and Google files, Gemini saves you time right where you already work. During the training, we help you decide based on your real case, and sometimes the answer is to use both.Gemini or Claude: what's the difference for work?
Both are strong on long documents and reasoning. Claude often gets cited for nuanced writing and clean code. Gemini stands out on two concrete points: native Google Workspace integration (you use it inside Gmail and Docs without switching tools) and broad multimodal that handles image, audio and video. If your stack is Google, Gemini slots in without friction. In 1-on-1, we compare on your real tasks rather than abstract benchmarks, and we pick the tool that saves you time.How does Gemini integrate with Google Workspace (Gmail, Docs, Sheets)?
Gemini is built directly into the Workspace apps, not as a separate tool. In Gmail, it drafts and summarizes your emails. In Docs, it writes, rephrases and outlines. In Sheets, it helps you build formulas and organize data. And it can lean on your Drive files to answer with your context. That's Gemini's strongest argument against the competition. In training, we set the right reflexes inside each app so you stop copy-pasting from one tab to another.What is a Gem on Gemini and what's it for?
A Gem is a customized Gemini assistant, the equivalent of custom GPTs. You give it persistent instructions (its role, its tone, the context to apply) and you can anchor it to specific files, like Google Docs or Sheets through Drive, for more relevant answers. Concretely: a Gem that always answers in your brand voice, or that knows your knowledge base without you re-pasting the excerpts. You can also share it with your team. In training, we build one on your real repetitive tasks to save you from rewriting the same prompt.Do I need to code to take the Gemini training?
No, not at all for most of the program. Writing good prompts, tapping the multimodal, using Gemini inside your Workspace and building a Gem all happen without a line of code. Code only becomes useful if you want to plug the Gemini API into your product or your automations, and that's an optional step. The 1-on-1 format starts from your exact level: total beginner, we go step by step; seasoned dev, we jump straight to the API, function calling and automation through Apps Script. You choose how far you go.What is Deep Research on Gemini?
Deep Research is an agentic mode of Gemini that does real research before answering. Instead of replying in one shot, it plans a strategy, runs dozens of queries, reads the results, spots gaps, runs follow-up searches, then hands you a structured, sourced report. It can also pull from your Workspace content (Gmail, Drive) for a more personalized report. Handy for a market study, competitive monitoring or a deep synthesis. In training, we use it on one of your real topics so you leave with a usable deliverable.Is the free version of Gemini enough or do I need to pay?
It depends on your usage. The free version already handles chat well, basic multimodal and writing help. The pro features (extended Deep Research, full Workspace integration inside Gmail and Docs, Gems shared with admin controls, more powerful models) come with the paid plans and Google Workspace subscriptions. In 1-on-1, we look at your real need before pushing you to pay: we often start on the free tier to validate the use, then switch only if a paid feature genuinely unblocks you.Is my business data protected with Gemini?
For professional use, it's a key point we frame. With Google Workspace plans, Google states it doesn't use your content (emails, documents, Drive files) to train its models, and your data stays within your organization's scope. The free consumer version has different rules, worth knowing before you put sensitive data in it. In training, we review your plan, what you can and can't put in it, and the right privacy reflexes for your team before deploying Gemini on your real documents.
