ChatGPT, Claude & Google Gemini

Three assistants, one job

All three are large language models you chat with in plain English (or French). They draft text, answer questions, summarize documents, help with code, and brainstorm ideas.

You don't need all three — pick one primary and keep another as backup. Many professionals use ChatGPT for speed, Claude for long documents, and Gemini if you're deep in Google Workspace.

Mobile tips for Rwanda

Install the official apps on Android — they work on mobile data. Save prompt templates in Notes or WhatsApp "Saved Messages" for one-tap reuse.

If the connection drops mid-response, copy partial output before refreshing. Shorter prompts use less data and respond faster.
