The Reply Project By GMass

What is The Reply Project By GMass?
GMass built The Reply Project By GMass to put your inbox messages on one screen so you can respond without opening each thread separately. You sign in with Google, load your inbox or any Gmail search results, and type replies in boxes beside each message. It runs as a standalone product, and you do not need a paid GMass plan to use it.
Most inbox workflows still make you click into one email at a time. The Reply Project By GMass lines up every matching message on a single page with a reply field next to each one, which is why GMass pitches roughly 10x faster reply clearing. It also includes built-in ChatGPT drafting and reusable templates without requiring your own ChatGPT account, a layout Gmail's default reply view does not match.
Support reps, recruiters, and salespeople who answer similar messages all day get the most from it. You can search Gmail for job applicants or customer threads, reply in batch, archive or delete from the same view, and use shortcuts like Control+Y for ChatGPT or Control+M for templates. It works only with Gmail and Google Workspace accounts, not other email providers.
ChatGPT Services

What is ChatGPT Services?
ChatGPT Services hosts Gmail add-ons from Klart AI that write, translate, summarize, and analyze email inside your inbox. AI Mail Assistant adds reply generation, draft polishing, 13-language translation, ChatGPT Q&A, and tone or ethics analysis to Gmail through the Google Workspace Marketplace.
Unlike standalone ChatGPT tabs, these tools live in Gmail's sidebar so you generate replies, insert drafts, and translate threads without switching apps. A separate AI Label Assistant product auto-labels and archives mail on an hourly schedule using your existing Gmail labels, with custom instructions when label titles alone are not specific enough.
The suite also includes Klart Prompts for GPT, Midjourney, and reverse prompt engineering. Plans start with 10 free AI Mail Assistant requests per month, paid tiers from €4.99 monthly, and Stripe or PayPal billing with cancel-anytime subscriptions.
