reply without overthinking it

OKEight is an AI reply generator that learns how you talk to each person, drafts beside any text box, and turns what you say into something ready to send.

send the reply before it becomes a whole thing

OKEight reads the conversation around you and suggests replies right where you’re typing.

double-tap ⌥ to draft

It reads the conversation in front of you and drafts a few replies beside the text box. Use ← → to pick one, then press ⏎.

hold ⌥ to talk

Hold it down, say what you mean, then let go. OKEight turns it into a reply. Your Mac handles speech recognition by default, so the audio stays on your device.

You still hit send. We’re not giving AI custody of your relationships.

what OKEight adds to the conversation

It uses the thread to learn how you write, adjust a draft, translate a reply, and turn settled plans into calendar events.

01

learn how you write

OKEight learns the way you phrase things, can learn from your past conversations, and gets better from the replies you choose.

It starts to get how you talk.

02

answer from a doc you drop in

Add a PDF to your Home page as knowledge, and the draft answers straight from it.

Your real numbers and terms go into the reply — no copy-paste.

03

stick your tongue out

One frame reads your expression, so the draft follows your mood.

The photo is never saved or uploaded. Only a mood label enters drafting.

04

turn settled plans into calendar events

Once the thread settles on a time, an event card appears beside the draft.

Check the title, time, duration, and people before adding it.

05

no more email procrastination

Draft beside a long email thread without copying it into another window.

Read the thread, choose a reply, and put it back into the same email.

06

remember your corrections

Tell OKEight how this reply should change. It rewrites the draft and remembers the preference where it fits.

Markus

One correction becomes a situational preference, not a blanket rule for every conversation.

07

translate the reply before you send it

See the translation, the point of the thread, and where each option is headed.

Markus
Could we move our sync to Thursday? Same time.
OKEightCandidate 1 / 3
Thursday works. Same time is fine. I'll update the invite.

The English draft stays untouched while you decide what to send.

the reply changes with the person

OKEight keeps a local relationship card for each person, so a note to your manager does not sound like a text to your closest friend.

OKEight adjusts to who you're talking to. Your boss and your bestie aren't getting the same version of you.

every chat gets its own version of you

Draft in Slack, Gmail, Lark, or any text field. OKEight keeps the people, promises, and dates that matter after you send.

questions worth asking first

The practical version of what OKEight does and what it leaves up to you.

Okay, but why not just paste the chat into ChatGPT

OKEight is a reply generator that lives beside the text field you're already using. It reads the chat when you ask for help, then drafts a reply in your voice using the tone and relationship context saved on your device. You can absolutely paste the chat into ChatGPT. You'll just need to explain who you're talking to, how you normally sound, and move the answer back yourself.

Can I use it where I already text people

Current-page drafting works beside readable text fields, so a channel connection is not required just to write a reply. Connecting Gmail, Slack, or Lark adds structured history that can improve voice, relationship context, and follow-ups. Apps that do not expose readable text can use a cropped screenshot of the visible conversation instead.

Will every reply have that painfully obvious AI vibe

No. OKEight learns from messages you have sent and can keep separate local context for each relationship. A friend, manager, client, and parent should not all get the same tone. Your manager still gets punctuation.

How does it pick up my texting style

Your sent messages are the writing examples. Incoming messages help explain the conversation, but they do not become examples of your voice. When you shorten a draft, make it less formal, or tell OKEight to answer the question first, that correction can become a local preference for the next similar situation.

Can it remember the stuff I said I'd do

Connected conversations can surface an unanswered question, something you promised to send, a decision waiting for confirmation, or a time that still needs to be settled. OKEight collects these as local items for you to review; it does not quietly complete or send them for you.

Can it check when I'm actually free

It can read free and busy times from a calendar you connect and suggest openings that fit the conversation. Once everyone agrees, OKEight can prepare the event details beside the reply. You check the details and decide whether to add it.

Wait, can it send stuff without me

No. Replies remain drafts until you review, edit, and send them. Calendar changes also wait for your confirmation. OKEight helps with the wording and the loose ends; the consequential button is still yours.

Is it reading my chats 24/7

Live reading begins when you invoke a draft. If you connect a channel, OKEight can also sync the history you authorize for voice, relationship context, and follow-ups. Long-term memory stays on your device; managed requests send only the context needed for the task through OKEight's proxy and the selected model provider. Read the full privacy details.

What if the draft fully misses the vibe

Choose another draft, edit it directly, or explain what went wrong. Your correction can help OKEight handle a similar reply better later. There is no prize for sending a bad suggestion quickly, and OKEight never removes your final review.

You could copy the conversation, open another AI tool,
paste it in, explain what you want, copy the answer back.
