Complete toolkit

One companion. Many ways to sound like yourself.

Draft, rewrite, switch persona, see the numbers, ask grounded questions — without pasting chats into someone else’s cloud.

Chat with confidence

Never blank again — and never upload your chats to get there.

Most AI reply tools ask you to paste screenshots or chat text into the cloud. Kepton flips that: you import an export you choose (or select/paste text for a quick action), then everything runs on-device — suggestions, rewrites, pattern insights, and Analysis.

Drafts are grounded in your conversation history and optional context you add. You review every line. You send what you mean.

  • Personalized reply draftsGrounded in chats you import — then shaped by the persona you pick (or Mirror, for your own learned style).
  • Instant rewrite helpAsk Kepton or Rewrite with Kepton on text you select — right from Android’s text actions.
  • See the patterns + ask questionsConversation insights for the numbers; Analysis for grounded observations — not character labels.
How it works
01

Import what you choose

Pick a chat export, review what will be stored, keep it encrypted on-device. Raw import files are deleted after parsing.

02

Download the model once

Start an optional one-time AI model download (size + consent first). After that, Kepton runs offline — no ongoing chat uploads.

03

Get drafts, insights, answers

Floating suggestions with your keyboard, text-selection rewrites, pattern insights, and on-device Analysis Q&A — even without internet.

What's inside

Everything that makes chat AIs useful — plus privacy tools .

Works with the keyboard you already use. (A built-in keyboard is not part of 1.0.)

Smart reply suggestions

A floating bubble or panel that helps you answer faster — drafts grounded in your own history and context you provide.

Personas

Switch tone (Friendly, Professional, Mirror…) or character energy (The Wit, The Detective, Casanova…) — all on-device, none of your chats uploaded.

Ask & Rewrite

System “Process text” actions — Ask Kepton and Rewrite with Kepton — on text you select or paste. Quick help without leaving the chat.

Conversation insights

Pattern metrics: message counts, reply timings, balance. Narration describes the numbers — not personality or relationship verdicts.

On-device Analysis

Ask questions about a conversation and get observations grounded in snippets and metrics. Helpful context — not professional advice.

Data Map + kill switch

See what lives on your phone, delete contact data anytime, and block further internet after setup. Transparency without a credits ledger.

Personas

Pick a vibe. Still sounds like you — on this phone .

Tone personas keep the register clear. Character personas add archetype energy — public-domain and fictional-feeling names, never trademarked TV lawyers. Switch before you suggest; review before you send.

Warm, casual, concise — easy everyday replies.

Also in the app: Supportive, Formal, The Closer, The Genius, The Prodigy, Birbal — browse them on-device anytime. Custom personas come later.

Why Kepton

Cloud chat AIs need your data. Kepton keeps it where it belongs.

You still get smart drafts and conversation help — without the “paste everything into someone else’s servers” tradeoff.

Typical cloud chat AI

Helpful — if you upload

  • Paste screenshots or chat text into a web app or API
  • Needs internet every time you want a reply
  • Your conversation content leaves your device
  • Often requires an account or credits
Kepton

Helpful — and stays local

  • Works from exports you import and text you select
  • Runs offline after an optional one-time model download
  • Personas, Insights, Analysis, Data Map, and a network kill switch
  • Your chats never leave your phone
  • No account. Encrypted on-device storage
Built for privacy

On-device processing. No sign-up. Clear about the one network step.

01 / On-device

Your chats never leave your phone

Imported chats, memory, and Analysis threads stay encrypted on the device. Webonika does not receive or store your chat content.

02 / Offline AI

100% offline after setup

After the optional one-time model download you start yourself, suggestions and insights run without internet.

03 / Network

What can leave the device

During model download, a CDN may see your IP and the fact of the download — not your chats. Then the kill switch can refuse further internet.

04 / No account

No sign-up. You are the author

No credits ledger for your private messages. Review every draft before you send — you remain responsible for what goes out.

FAQ

Straight answers before you install.

Is Kepton another cloud dating / chat AI?

No. Kepton is an Android app that processes conversations on your phone. It drafts reply suggestions and shows pattern insights from exports you import — it does not upload your chats to Webonika’s servers.

Do I need internet to get reply suggestions?

Only for an optional one-time AI model download you start yourself (with size shown and consent first). After that, suggestions, Insights, and Analysis run offline.

Will replies sound like me?

Drafts are grounded in your own conversation history and optional context you add. Choose Mirror to lean into your learned style with that contact, or pick a tone/character persona for the vibe you want — then review and edit before sending.

What are personas?

Built-in reply styles: tones like Friendly, Professional, Supportive, and Mirror, plus character archetypes like The Wit, The Detective, Casanova, Chanakya, and more. They change how drafts read — they do not upload your chats or label people.

Can Kepton access my messaging apps automatically?

No. It works from chat exports you choose to import, and from text you explicitly select or paste. It does not claim automatic access to your messaging apps.

Is this professional or relationship advice?

No. Insights and Analysis describe patterns in message data. They are not psychological, medical, or legal advice, and they do not assess anyone’s character.

Important

You review every draft. AI is a starting point.

Kepton helps you write faster and see conversation patterns. It does not replace your judgment. Outputs are not always correct — edit before you send. Not professional advice; not character labels.
