Who it's for

The inbox no one taught you
to keep up with.

If your job runs through LinkedIn DMs, you spend more time drafting replies than you'd like. Replyy is for the people who keep that inbox alive.

The point

Three drafts. Pick the one that sounds like you.

Open any LinkedIn DM, hit the Replyy button, get three genuinely different replies side-by-side. Click the one that lands — it drops into LinkedIn's compose box, ready to send.

  • Distinct angles per draft — not three rephrasings of the same line
  • Tones on tap: professional, casual, decline, follow-up, shorter
  • One click to insert, your finger to send

Your voice, learned

Sounds like you wrote it — because Claude read what you write.

Paste a handful of messages you've actually sent. Replyy weighs them into every prompt. The hedges, the rhythm, the way you sign off — your phrasing, not a generic chatbot's.

  • Add 5–10 voice samples in your dashboard
  • Profile-aware: knows the other person's title automatically
  • No "Hi {firstname}" autoresponder energy
Voice samples·3 added
"haha yeah, agreed — I think the bigger Q is whether we can pull it off in Q3"
"sure, let me bounce that off the team and circle back tomorrow"
"fair! I'll grab time on your cal — Thursday looks open"
On your terms

Bring your own Anthropic key. We don't see your DMs.

Suggestions run on your own API key. We relay the request to Anthropic; nothing about the conversation is persisted beyond your account's usage log. Cancel by deleting the device token.

  • AES-256-GCM at rest for stored keys
  • No token markup — pay Anthropic, not us
  • Multi-tenant from day one, self-host when you outgrow us

FAQ

Questions you'd reasonably ask.

Does Replyy see my DMs?+

The extension scrapes the conversation locally in your browser and forwards it to our backend for the duration of one API call, which then relays it to Anthropic under your own API key. DM content is never persisted — only metadata (thread title, tone selected, token counts) is stored on your account.

Will I get banned from LinkedIn?+

Nothing is automated. Every reply is a human click — Replyy drafts, you decide and send. LinkedIn's automation detection targets mass-scraping and auto-DM tools. That said, this is dual-use software: don't spam.

Why bring your own API key?+

Two reasons. One, you pay Anthropic directly — we don't mark up your usage. Two, your conversation content only ever touches the LLM provider you chose. We never become a single point of failure for your message history.

Which models can I use?+

Claude Opus 4.7 (highest quality, slower), Sonnet 4.6 (fast and inexpensive — recommended default), and Haiku 4.5 (fastest, cheapest). Pick the model in your dashboard. Platform admins can restrict which models users see.

Can I run this on my own server?+

Yes — single-binary by design. SQLite by default, swap to Postgres for production. The open-source release will follow the public-hosted SaaS.

Stop drafting replies at 11pm.
