Match the tool to the job you gave Claude. ChatGPT and Le Chat suit long writing jobs, GitHub Copilot and Cursor suit coding, Perplexity suits research with sources, Microsoft Copilot and Gemini suit work inside Microsoft or Google apps, and Ollama or LM Studio suit running a model privately on your own computer.
Claude is a strong all-rounder. But no AI assistant is the right fit for every job, and there are good reasons to look around: you've hit usage limits, your team already pays for another tool, you need live sources, or you'd rather keep sensitive work off the cloud.
So instead of one long list, I've sorted the options by the job you were using Claude for. Find your job, look at the one or two tools under it, and skip the rest. If you'd like the bigger picture first, my comparison of ChatGPT vs Claude vs Gemini for marketing covers how the big three differ.
Long documents and everyday writing
This is what most small business owners use Claude for: drafting emails, tidying up proposals, summarising long reports and turning rough notes into something readable.
ChatGPT
ChatGPT from OpenAI suits owners who want one assistant that does a bit of everything. It handles drafting, editing and summarising well, takes file uploads, and adds extras like image creation, voice chat and custom assistants you can set up for repeat tasks. There's a free plan to try it. Its main limit for writing is tone: drafts can sound generic until you give it examples of your own voice, so feed it a few of your past emails or posts.
Le Chat by Mistral
Le Chat is the assistant from Mistral AI, a French company. It suits people who want a fast, capable writing helper and like the idea of a European provider. It's quick, handles documents and has a free tier. Its limit is a smaller set of extras and integrations than ChatGPT, so it works best as a focused writing tool rather than your everything app.
Writing and fixing code
Plenty of people use Claude to write scripts, fix website snippets or explain errors. If coding is your main job, a tool that sits inside your code editor will save a lot of copying and pasting.
GitHub Copilot
GitHub Copilot suits developers and technical owners who already work in an editor like VS Code. It suggests code as you type, explains what a block does and can chat about your project. Its strength is that it lives where you work. Its limit is that it's built for people who code, so it won't help much if you only need the odd snippet for your website.
Cursor
Cursor is a code editor built around AI. It suits people who want to describe a change in plain English and have the tool edit several files at once. Many people find it handy for small projects, internal tools and quick fixes. Its limit is that you still need to review what it writes. Treat every change like work from a new junior hire: check it before it goes live.
Research that needs sources
When you need answers you can check, not just answers that sound right, use a tool that shows you where each point came from.
Perplexity
Perplexity suits research jobs: checking a fact, comparing suppliers, reading up on a new topic or pulling together recent news. It searches the web and shows numbered sources next to its answer, so you can click through and confirm. There's a free version. Its limit is that the answer is only as good as the pages it finds, so always open the sources before you quote anything to a client.
Working inside Microsoft or Google apps
If your business runs on Outlook and Word, or on Gmail and Google Docs, the AI built into those apps can be more useful than a separate chat window.
Microsoft Copilot
Microsoft Copilot suits businesses on Microsoft's work apps. Inside Word, Excel, Outlook and Teams it can draft documents, summarise email threads, recap meetings and help with formulas, using the files you already have. Its strength is context: it can work with your own documents. Its limit is that the full in-app features depend on the right business plan, so check what your plan includes.
Gemini
Gemini is Google's assistant. It suits teams on Google Workspace, where it can help draft in Gmail and Docs, summarise files in Drive and work through data in Sheets. It's also a capable chat assistant in its own right, with a free version. Its limit, like Copilot's, is that the best in-app features depend on your Workspace plan.

Running a model privately
If you handle sensitive material and don't want it leaving your computer, you can run an open model locally. You'll need a reasonably powerful machine, and the answers won't match the biggest cloud models, but your data stays with you.
Ollama
Ollama suits people who are comfortable with a bit of setup. It's free, open source software that downloads and runs open models on your own computer, and other apps can connect to it. Its limit is that it starts from the command line, which puts some owners off.
LM Studio
LM Studio suits non-technical owners who want the same idea with a friendly app. You browse open models, download one and chat with it in a window that feels like any other AI tool. Its limit is speed and quality on an older laptop, so start with a small model.

What to check before you paste client data into any AI tool
Whichever tool you pick, this matters more than the choice itself. Run through these checks first:
- Training settings. Find out whether your chats can be used to train the provider's models, and switch that off where you can.
- Business plans. Team and business plans often come with stronger data controls than personal accounts. Read what your plan promises.
- Your client contracts. Some contracts and NDAs limit where client information can go. Check before you paste anything.
- Strip the details. Remove names, emails, account numbers and anything personal. You can usually get the same help with placeholders.
- Ask when unsure. For anything covered by data protection law, check with your adviser rather than guessing.
