## Code Arena

Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.

**料金とプラン:** Free to use; no paid tier is advertised on the product page. Related enterprise/API offerings from Arena may be priced separately.

- **Model battles:** Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
- **Real-time app building:** Watch models construct web apps and websites live, so you can see process and output, not just the final file.
- **Multi-file generation:** Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
- **Community leaderboard:** Track which coding models accumulate the most wins over time to identify consistently strong performers.
- **Free browser access:** Run comparisons directly in the browser without installing anything or paying for credits.

**強み:** Free, no-signup barrier for quick comparisons; Tests full multi-file projects, not just isolated snippets; Live battles reveal model behaviour, speed, and failure modes; Leaderboard aggregates community signal over time

**制約・デメリット:** Battles are subjective and depend on the prompts you write; Not a full IDE replacement for day-to-day development; Leaderboard results can shift quickly as new models ship

## NextDocs

NextDocs is an AI workspace that turns a prompt and your own files into finished presentations, reports, spreadsheets, web pages, and social posts. Rather than handing back a rough draft, it builds a branded, structured deliverable with layouts, charts, and your logo and fonts already applied, which you can then refine by hand or with AI and export to PowerPoint, Google Slides, PDF, Word, or Docs.

**料金とプラン:** NextDocs is freemium. The free plan includes monthly AI credits and core creation and export features, with no credit card required. Paid Pro and Pro+ tiers raise credit limits, unlock premium AI models, extend page counts, and add AI image editing and priority support. Unused credits do not roll over, and refunds can be requested within 30 days.

- **One Agent, Every Deliverable:** Describe the deliverable and NextDocs builds it with real layouts, charts, and structure — presentations, reports, proposals, web pages, and spreadsheets.
- **Brand Kit:** Upload logos, fonts, and colors once; new documents inherit the brand system automatically so teams stay visually consistent.
- **Multiple Versions & AI Editing:** Choose from up to four variants per prompt, then rewrite sections with AI or make precise manual edits in a full editor.
- **Deep Research:** Research-backed generation pulls in real inputs rather than generic filler, which matters for reports, whitepapers, and strategy decks.
- **Universal Export:** Export finished work to PowerPoint, Google Slides, PDF, Word, and Google Docs so it fits existing workflows.
- **Bring Your Own Agent:** The Mac app connects Claude Code or Codex so your own agent works on your files, and any task can be scheduled to run on a recurring basis.

**強み:** Produces finished, formatted deliverables rather than drafts; Brand kit applies your logo, colors, and fonts automatically; Multiple output formats from one prompt, including decks, docs, pages, and spreadsheets; Exports to PowerPoint, Google Slides, PDF, Word, and Google Docs

**制約・デメリット:** Credits reset monthly and do not roll over; Newly generated presentations export to PowerPoint as one image per slide rather than editable native elements; Fixed-page Word and Docs exports use positioned text, so heavy edits need a layout check; Free plan credit allowance is limited, pushing frequent users to a paid tier
