Everything you need to know
Do I need an account to use the writing assistant?
Yes. The AI writing assistant requires an Office Tools account with a paid plan (Plus or higher) because each operation consumes language model resources. It is not included in the free Starter plan.
Can I use the AI assistant with the free Starter plan?
No. The free Starter plan does not include the AI assistant. The Plus plan includes 5 daily operations on texts up to 2,000 words; the Pro plan expands to 30 daily operations with 5,000 words and unlocks advanced tones, export and history. The Business plan goes up to 100 daily operations with no word limit and lets you choose between Claude, OpenAI GPT and Gemini.
Which AI models does the assistant use?
Office Tools routes your requests to the model configured by default (Claude by default, configurable to OpenAI GPT or Google Gemini). Business plan users can manually pick the provider from inside the tool.
What operations can I run?
Summarize (one paragraph, 5 key points or a full summary), rewrite, change tone (formal, informal, simplified, persuasive or technical), fix grammar and spelling, expand, condense, translate between 13 languages with automatic detection and draft emails from key points (includes quick templates).
Which languages can I translate to?
The AI translator supports 13 languages: English, Spanish, French, German, Italian, Portuguese, Catalan, Basque, Galician, Dutch, Russian, Chinese and Japanese. It automatically detects the source language and lets you adjust register (neutral, formal or informal).
Does the assistant store my texts?
Office Tools logs each operation in your personal history so you can review it later (history access available on the Pro plan). Your texts are not used to train models. You can delete your history from the dashboard whenever you want.
Can I use the assistant for academic texts?
Yes, especially to fix grammar, improve writing, summarize chapters or translate bibliography. Remember that academic rules require original authorship: use AI as a support tool, not as a replacement for intellectual work.
