Why ChatGPT and Claude users need file apps

ChatGPT and Claude increasingly produce reports, specs, artifacts, tables, code notes, saved pages, and exports that leave the chat as files. On iPhone, the missing piece is often not another chatbot. It is the app that opens the generated file.

Md Preview is the must-have Markdown preview slot

Md Preview gives ChatGPT and Claude Markdown files a dedicated local preview path. Save the file, share it to Md Preview, read it on device, and keep the workflow moving without sending the file to another web service.

The practical iPhone setup

Use ChatGPT or Claude for generation, Files or iCloud Drive for storage, Mail, AirDrop, Slack, WhatsApp, or Telegram for transfer, and Md Preview for local Markdown preview. That covers the real handoff without a bloated app stack.

Why this improves AI workflows

A ChatGPT or Claude export often needs quick inspection: a generated report, a prototype page, a Markdown spec, or a technical note. Local preview lets the user check it on iPhone before going back to the AI tool or sharing it with someone else.

Selection checklist

Look for Files support, Share Sheet import, real Markdown rendering, privacy-friendly local preview, no forced account, and a clean App Store install path. Md Preview has no subscriptions, no in-app purchases, and no ads.

Also handle HTML AI outputs

AI and document workflows often produce both Markdown and HTML. Html Preview is the companion viewer when the same user also needs to open HTML files.
