What makes the drafts good

Three layers of context. One reason every draft sounds like you.

A generic LLM gives you generic replies. Reply Copilot stitches your team's voice, your shop's knowledge, and your past edits into every draft — automatically.

Per-teammate voices

Sounds like the rep, not a chatbot.

Each teammate has their own voice profile — paragraph rhythm, signoff block, length cap, the phrases they actually use. Sara writes warm and casual; Andrew leans formal. The AI matches whoever's logged in.

  • Mimic-my-writing extractor
  • Default voice per rep
  • Multi-line signoff support
Your shop knowledge

Knows your policies, not generic ones.

Upload your FAQs, return policies, and product specs once. Every draft pulls only the chunks relevant to the customer's question via semantic search — not a wall of unrelated text the model has to wade through. Plus listing details and order info auto-grabbed from the page.

  • Semantic FAQ retrieval
  • Listing + order auto-pull
  • Image-aware: reads customer photos
Learns over time

Gets sharper with every edit.

Tweak a draft and send it. We silently save it as an example. Every week, recurring edit patterns get distilled into one-click voice and KB updates in your Suggestions inbox. Approve the pattern once, and the AI applies it to every future draft, not just similar ones. Your voice compounds without you configuring anything.

  • Auto-captured rewrites
  • Weekly suggestions: distill edits into voice and KB updates
  • Few-shot retrieval at draft time
Your AI doesn't plateau — it learns from every send.

Every reply where you tweak the draft becomes training data for next time. The more your team uses it, the more it sounds like your team.

✨ Why not just ChatGPT?

Because copy-paste is the slow part.

ChatGPT is great. But it doesn't live where you work, doesn't know your shop, and doesn't learn your team's voice.

The slow way

ChatGPT round-trip

  • Bouncing between eBay, ChatGPT, your FAQ doc
  • You paste your FAQs every time
  • You retype item details into ChatGPT
  • One generic ChatGPT tone for the whole team
  • Same prompt forever — no learning
  • No record of what was sent or by whom
⚡ The fast way

Reply Copilot

  • One tab — inside Seller Hub
  • Centralized FAQ, always loaded
  • Auto-pulled: title, condition, shipping, returns, order status
  • Per-rep voice profiles — your team, your voices
  • Learns from every edit — voice compounds over time
  • Activity log + edit-distance per reply
⭐ From real sellers

Sellers who stopped rewriting the same reply

From solo resellers to 6-rep CS teams — Reply Copilot adapts to how you work.

“Our CS team was buried in eBay messages — easily 4–5 hours a day across 4 reps. Reply Copilot cut that by about 90%. The drafts actually sound like us — customers can't tell.”

“I was copy-pasting from a Google Doc of canned replies. Reply Copilot reads the actual listing and order status, so I don't have to hunt for tracking numbers or policies anymore.”

“The voice learning is what sold me. After a week of tweaking drafts, it started nailing our tone without edits. My team went from sending 60% of drafts as-is to about 85%.”

“Tried using ChatGPT but I had to paste the message, the listing, the order page every single time. Reply Copilot pulls it all in automatically. Two clicks and it's done.”
