Which AI for Which Task?

New AI tools appear every month, and there is no single right answer to "which AI is best?" The better question is: "Which one for this task?" Because one model shines at writing text, another at generating code, another at creating images. This guide groups popular tools by the job you need done and offers a balanced view.

Note: In AI, capabilities, limits and prices change very fast. The information below is a general pointer; check each tool's official page for exact current features and pricing, and where possible run a small test with your own work.

1. Writing, brainstorming and general chat

The most-used chat assistants for general text generation, summarising, email drafting and idea development:

• ChatGPT (OpenAI): The most widely known general-purpose assistant; stands out with a broad plugin/tool ecosystem.
• Claude (Anthropic): Known for following long text and for careful, structured writing; often preferred for long-document analysis.
• Gemini (Google): Notable for integration with the Google ecosystem (Search, Workspace).

Practical tip: Try the same prompt in two or three tools, compare tone and accuracy, and pick your "default" tool based on your own work.

2. Coding and development

For software development, debugging and explaining code:

• GitHub Copilot: Common for inline completion and suggestions inside the editor.
• Claude and ChatGPT: Considered strong for longer reasoning, refactoring and "why is it like this?" explanations.
• AI-first editors like Cursor: Combine model power directly with your codebase.
• Gemini: An integrated option for those developing within the Google environment.

While building, most of your time goes into data; use the JSON Formatter to read API responses, the JWT Decoder to inspect tokens, and the Base64 Encoder to decode bodies — all in your browser, with your data never leaving the page.

3. Up-to-date information and research (cited search)

For current, source-cited answers from the web:

• Perplexity: Known for search-focused answers with source links.
• Gemini and ChatGPT (with web access on): Usable for current events and referenced summaries.

Important: AI can "make things up" (hallucinate). For critical decisions, always verify answers against their source.

4. Images and design

For text-to-image generation and image editing:

• Midjourney: Known for artistic, high-aesthetic images.
• DALL·E (OpenAI) and Google Imagen: Fast image generation integrated into chat assistants.
• Stable Diffusion: Open source; for local/self-hostable and customisable workflows.
• Adobe Firefly: Focused on commercial use and integration with design tools.

When you need to optimise generated images for the web, tools like the Image Cropper, Image Compressor and SVG to PNG round out your workflow.

5. Audio: voiceover, transcription and music

• Voiceover (TTS): ElevenLabs is known for natural voices. For a quick/free alternative that uses your browser's built-in engine, try our Text to Speech tool.
• Speech to text: OpenAI Whisper is widely used for transcription. For a quick in-browser test, use the Speech to Text tool.
• Music: Suno and Udio are prominent for text-to-music generation.

6. Data analysis and spreadsheets

For tabular data, analysis and charts, ChatGPT (code interpreter), Claude and Gemini offer options that can upload and analyse files. When structuring your data, tools like CSV to JSON and the JSON Formatter make prep easier.

7. Running on your own server (open models)

If you want to host the model yourself for privacy, cost or customisation, open-weight models like Llama (Meta) and Mistral stand out. They can be attractive for teams that need enterprise data privacy and low marginal cost.

How to choose the right tool

1. Define the task: Text, code or image? Pick by task rather than hunting for one "does-everything" tool.
2. Test with your own data: General comparisons are a guide; the real result is decided by your typical task.
3. Measure cost and speed: At high volume, token price and latency matter.
4. Mind privacy: Read the terms before sending sensitive data to a third-party model; consider open/self-host models if needed.
5. Use more than one tool: Most professionals don't stick to a single tool — they switch by task.

Summary

There's no single "best AI" — there's a best fit. One assistant may lead for writing, another for code, another for images. Choose the tool by task, test with your own data, watch cost and privacy — and because the field moves fast, revisit your choices from time to time.
