Many Replies

Inbox triage

Every incoming thread sorted by stakes: urgent, lead, customer, admin, noise. You see only what moves the needle.

Replies in your voice

Koan learns your tone from sent mail and writes drafts that read like you, not like a template.

Lead qualification

Inbound prospects scored against BANT in real time. Hot leads bubble up, tire-kickers get a polite holding pattern.

Follow-up sequences

The deal you forgot about gets a third nudge on day 12. The proposal you sent gets a check-in on day 4. Koan never forgets.

Invoice chasing

Outstanding invoices tracked and chased in your voice. Day 7, day 14, day 30. Firm but polite. You stay paid.

Meeting scheduling

Calendly-quality coordination without the link. Koan offers slots, books holds, reschedules when life happens.

Quote and proposal drafts

When a buyer says yes-tell-me-more, Koan drafts the proposal: scope, price, terms, signature link.

Cross-language replies

Reply in the language of the sender, automatically. French, English, Spanish, Thai, German. Your customer feels native.

Attachments handled

Contracts, invoices, receipts. Koan reads them, summarizes them, and references the right page in the reply.

Autopilot or hold for approval

Per category: full autopilot for routine threads, hold-for-approval on anything over a revenue threshold you set. You stay in control.

Revenue insights

Which threads are stuck. Which contacts are heating up. Which dollars are still in the air. Plain English, weekly digest.

Chat-native control

Brief Koan on Slack, WhatsApp, or web. Tell it your priorities for the day, change tone for one contact, ask for status, all in chat.

Koan handles
every thread.

Koan turns email
into revenue.

Closes the warm leads.

Every inbound lead gets qualified, scored, and replied to in minutes. Koan picks the threads worth your attention and warms the rest until they're ready to buy.

Chases unpaid invoices.

Late payments tracked automatically. Koan sends the firm but polite follow-up at day 7, 14, 30, in your voice. You stay paid, you don't have to nag.

Replies to every customer.

Support questions, booking requests, pricing inquiries: answered within the hour, in your house voice. Koan only escalates when a human is actually needed.

Surfaces what matters.

Threads ranked by revenue at stake, not by who emailed last. Koan tells you which 3 messages today are worth opening and handles the other 80.

No new app.
Just connect Koan.

Gmail, Google Workspace, or any inbox via IMAP (Hostinger, OVH, custom domains). Five-minute connect, your messages stay where they are. Koan reads, drafts, and sends in your name from the inbox you already trust.

Anything else
on your mind?

What's an "email handled" exactly?+
One email handled = one inbound email Koan reads, classifies, and drafts a reply for (or routes to a category, or applies a rule on). Regenerating a draft never counts as a new one. Starter includes 200/mo (~10 emails per business day), Active 1,000/mo (~50/day), Studio 5,000/mo + fair-use up to 10k. Anything above your quota is billed per-email at the overage rate shown on each tier.
Why an AI agent instead of a virtual assistant?+
A trained VA costs $1,500–$3,500/mo, takes weeks to learn your voice, sleeps, and never matches your tone perfectly. Koan answers in your voice from day one, works 24/7, never misses a follow-up, and costs from less than $3/day on Starter.
How does Koan actually read my email?+
OAuth, scoped to the inbox you connect. Koan reads incoming messages, drafts replies in a sandbox, and only sends what you (or your rules) authorize. Your password is never stored, no IMAP credentials in plaintext, revoke access in one click from your Google or Microsoft account.
Will replies sound like me, or like a robot?+
Koan reads the last 500 emails you sent, learns your phrasing, sign-offs, formality level, and stops you'd consider important. Drafts read like you on your best day. You can edit any draft inline before it sends, and Koan learns from every correction.
What happens if Koan makes a mistake?+
Per category, you choose: autopilot or hold-for-approval. We recommend hold-for-approval for the first two weeks, autopilot once you trust the drafts. Anything above a revenue threshold you set (say, deals over $5k) always waits for your green light, regardless of mode.
What's the Opus add-on?+
Sonnet 4.6 is the default model and handles 95% of replies beautifully. The Opus add-on routes high-stakes threads (large deals, key contacts, negotiation tone) through Claude Opus 4.7 for the deepest reasoning. Billed per email handled by Opus at $0.20 each. Studio includes Opus on-demand at no extra charge.
Annual or monthly?+
Both work. Annual gets you two months free (about 17% off) and locks in your rate against future price changes. Cancel anytime, refund prorated to the day. Monthly is no-strings-attached.
Where does my data live?+
Your email content is processed in the EU under GDPR. Drafts and metadata are stored encrypted at rest. We don't train foundation models on your data. You can export everything or delete the workspace from settings at any time.
Can I cancel anytime?+
Yes. From your billing portal, one click. No retention call, no paperwork. Subscription ends at the current billing period and Koan disconnects from your inbox automatically.
Do I have to talk to anyone to sign up?+
No. Onboarding is fully self-serve, about five minutes: email + password, workspace name, brand voice, connect Gmail or Outlook, pick which categories you want on autopilot. Prefer a human walkthrough? Book a call. But you don't need one.
