ChatGPT: OpenAI's AI assistant for your freelance business

ChatGPT is OpenAI's AI assistant. You write to it (or talk to it) and it drafts, summarizes, translates, rephrases, analyzes a contract or a screenshot, searches the web, generates images and writes code. It runs on the GPT-6 and GPT-5.6 models, with reasoning models for complex tasks. It is available on web, iOS, Android, as a desktop app, and as add-ins in Excel, Word, PowerPoint and Google Sheets. It is the most widely used AI assistant in the world, and the one your clients already know.

For all freelancers who produce text, analyze documents or want a fast first draft: writers, consultants, community managers, developers, trainers. Its advantage is breadth: one tool for a follow-up email, a visual for a post, a spreadsheet analysis and an automation script. If you mostly work on long texts in French or large documents, compare with Claude. If you want a European AI, look at Mistral AI. And for sourced research, Perplexity remains a reference.

At FreelanceKit, we picked ChatGPT because it is the most complete assistant for an independent who does a bit of everything: writing, analyzing, illustrating, coding. The free plan lets you use it seriously for text, and the Go plan at €8 per month is the lowest entry ticket among the major assistants. Prices are shown in euros, which avoids currency surprises.

The weak point to know about: usage limits. On the free plan, you hit the ceiling quickly on file uploads, images and deep research, and the Go plan may show ads. For daily professional use with documents, Plus at €23 per month is the real entry point, and the jump to Pro at €103 is significant. Finally, by default your conversations may be used to train the models: turn off the option in the settings if you handle client data.
