What it does

Three tools. One voice.

Koiné is a web app (PWA) for group admins who reply on Facebook and post on social media. Everything runs in the group's persistent voice.

Reply to comments

Home · Claude Haiku 4.5
  • Paste any Facebook comment
  • Get 2 calm reply variants in the comment's language
  • Auto-classified: praise, question, constructive critique, harsh critique, misinformation, political bait

Generate social posts

/postari · Claude Sonnet 5
  • Facebook, Instagram, LinkedIn or generic
  • 6 post types × 4 tones × 3 lengths — 3 variants each time
  • Optional hashtags + auto-translated to Greek

Voice profiles

/profiluri
  • Persistent "code of communication" per group
  • Multiple profiles per tenant — one for Facebook, another for Instagram, etc.
  • AI-assisted profile creation: describe the group, Claude drafts the code
Every reply is an open door. Koiné's philosophy is de-escalation. It never invents facts, dates or numbers — it leaves [___] for you to fill in. It never gets into political or personal fights. It thanks even for critique.
How it works

Paste. Read. Copy.

You never leave the app for social media. Koiné hands you drafts — you decide what to post.

1. Paste

A Facebook comment for replies, or a brief for a post. Under 5000 characters.

2. Read

Claude generates variants using your voice profile as the system prompt. 2 variants for comments, 3 for posts. Detected language + comment type shown.

3. Copy

Edit inline if you want. Copy to clipboard. Paste on Facebook. Koiné does not post for you.

Honest about AI

What we send, where it goes, who sees it.

No black box. Here is exactly what Koiné does with your data.

Self-hosted on our server

Your users, profiles and generation logs live in a PostgreSQL database on the livos server. Not on a third-party SaaS. Backups included.

Claude by Anthropic

The generation itself runs on Claude (Haiku 4.5 for replies, Sonnet 5 for posts) via Anthropic's API. Your comment + voice profile go to Anthropic. Nothing is used to train models.

2FA mandatory

Every account requires TOTP (Google Authenticator, Authy, 1Password). Sensitive actions require re-verified 2FA — no exceptions.

Every generation is logged. Comment, profile used, model, variants, latency — all saved for audit. You can review who used AI when, for what group, from where.
