What We Mean by AI Assistants
Modern assistants plan tasks, draft content, analyze documents, and call tools. They help you think, write, code, and decide with fewer tabs and cleaner handoffs. The best choice depends on your primary job to be done, not on a single benchmark.
Common tasks
- Content drafting and editing with a consistent tone
- Document review and structured summarization
- Code generation, refactor, and explanation
- Research synthesis with citations and checks
- Image and media understanding in multimodal flows
How We Evaluate
Creativity and style control
Range of tones, story structure, hooks, and ability to keep brand voice stable across drafts.
Technical accuracy and reasoning
Precision for code, math, policy, and stepwise analysis with low error rates.
Research and grounding
Ability to work with long inputs, extract facts, and surface uncertainties clearly.
Multimodal handling
Reading images and media, describing scenes, and pairing text with visuals.
Privacy, control, and compliance
Data handling options, redaction patterns, and enterprise friendly controls.
Value and ecosystem fit
Fit with your daily tools, availability of extensions, typical paid tiers.

Sample Prompts that Play to Each Strength
ChatGPT, campaign ideation and hooks
You are a senior brand copywriter. Create 12 headline and subheadline pairs for a spring campaign.
Brand voice, warm, simple, optimistic
Audience, busy parents
Product, eco friendly cleaning kit
Constraints, 7 words max for headlines, include a benefit verb
Deliver, table with columns, Headline, Subheadline, AngleClaude, long doc analysis and code review
You are a meticulous staff engineer. Review this PRD and the code diff.
Goals, identify logic risks and test gaps
Provide, risks list, test plan, and acceptance criteria
Tone, concise and neutral
Input, paste PRD section and diff hereGemini, research synthesis with checks
You are a research assistant. Summarize the latest viewpoints on topic X.
Include, key arguments, counterpoints, and a 5 item reading list
Add, where uncertainty remains and what to watch next
Format, markdown with bullet points and short paragraphsPrivacy and Control
- Set least privilege access and isolate secrets
- Redact sensitive fields in prompts and attachments
- Log queries and outputs for audits and training
- Require human review for customer facing materials
If strict controls are required, start with policies in security and use grounded retrieval from your own sources.
Common Mistakes and How to Avoid Them
- One size fits all, use the tool that fits the task
- No grounding, attach context or retrieval for facts
- Unclear prompts, specify role, audience, constraints, and format
- No review loop, add a short checklist before publish
- Ignoring cost, save best prompts and reuse templates
Conclusion
ChatGPT wins for creative breadth, Claude leads for careful technical work, and Gemini shines for research and multimodal tasks. The most productive path is often a two tool setup matched to your main workloads. When you are ready to decide, open compare or see all AI tools, then add supporting picks from writing, research, and coding.
