The AI choice guide

Choose AI for the work you do.

For professionals and small teams. Start with your task, understand the trade-offs, and check the evidence before committing.

Documentation-based assessment · No hands-on results or numerical ratings. Suitability statements are editorial judgments to help you plan your own evaluation.

Assistant app

Claude

An assistant for working through documents and drafts, with web search and connected tools.

Document analysis · Research · Writing

Shortlist it for reviewing documents or drafting with source material. Test whether the supporting passages are accurate before relying on its answers.

Research app

Perplexity

A search-oriented assistant with basic search, Pro Search and file analysis access that varies by plan.

Research · Document analysis

Shortlist it for search-led research. Compare how much checking the answer needs against a document-led assistant before paying for higher limits.

Automation platform

Zapier

Connects applications through workflows; AI steps can be part of a larger automation.

Automation

Shortlist it when the job is moving data between apps. Specify the trigger, permitted action and recovery procedure before comparing it with another automation platform.

Assistant app

ChatGPT

An assistant for questions, research and working with source files and drafts; Work supports multi-step tasks and deliverables.

Document analysis · Research · Writing

Shortlist alongside Claude and Perplexity for research and document work. Use identical source material and measure how much verification and editing the output needs.

Coding agent

Codex

Works with codebase context to inspect files, make changes and run development commands, with terminal and IDE workflows.

Software development

Shortlist for a bounded issue in a repository. Compare the final diff, test results and manual repair effort with another coding agent once its profile is reviewed.

A useful comparison begins with a question.

Compare two or three products using the same criteria. Prices, plan conditions and limitations come from the same records as these profiles.

Compare the evidence →

Document analysis: Can I trace each answer back to my document?

Use the same non-sensitive document and ask for exact supporting passages. Verify omissions and unsupported answers before comparing speed.

Research: Can I verify the evidence behind this answer?

Compare source quality, publication dates and the time needed to check claims. A linked source does not prove an answer is correct.

Writing: Does the draft meet my brief with less editing?

Use a fixed audience, source material and acceptance checklist. Count factual repairs and editing time separately from generation time.

Meeting notes: Can it capture decisions without inventing actions?

No dedicated meeting recorder has been reviewed in this first collection. Do not treat a general assistant as a verified recording or transcription service.

Automation: Can I control what the workflow is allowed to do?

Start with a reversible action and non-sensitive sample data. Check permissions, failure handling and usage costs before enabling unattended actions.

Software development: Does the change solve the task and pass review?

Use a small repository and a fixed issue. Inspect the diff, run the project tests and record manual fixes. Codex is the first dedicated coding agent covered here; a head-to-head coding assessment needs another reviewed coding product.
