1

Paste the email you received

Start in the web app by pasting the message you need to answer. The core workflow does not require connecting your inbox.

2

Choose tone and reply length

Pick the tone and length that fit the situation, and add a short instruction when you want to steer the reply.

3

Generate, review, and send

RepliStack drafts a ready-to-send reply you can edit, copy, and send from your normal email workflow.

What makes it useful

Built for people who reply to a lot of email and want a faster, steadier workflow.

  • Save time on repetitive replies, follow-ups, and client emails.
  • Keep replies clear and consistent when you are busy.
  • Reduce the blank-page friction that slows down fast responses.
  • Handle support questions, scheduling emails, and sales follow-ups with less rewriting.
  • Use optional style training and support knowledge when you want more tailored drafts.
  • Stay in control by reviewing the final reply before you send it.

Privacy and trust

Clear about the workflow. Clear about the data.

We use Supabase for authentication and database hosting, Stripe for billing, OpenAI for reply generation, and Vercel Web Analytics plus Google Analytics for public-site measurement.

  • We do not store your emails on our servers. Email content is sent to OpenAI only to generate the reply.
  • We store minimal account data, usage counts, and subscription status.
  • Account required to track trial usage and subscription.
  • Google Analytics only runs if you accept analytics cookies, and you can change that choice later from Cookie settings.

Optional Chrome extension

Keep the core workflow in the app, then move faster in Gmail when you want to.

RepliStack also has a Gmail Chrome extension for a faster workflow. It is optional. The core product still starts with the web app flow: paste the email, guide the reply, generate the draft, then send with confidence.

Stop guessing what happens next.

RepliStack helps you turn the workflow into a ready-to-send reply in a few clicks.
