Encrypted WhatsApp Business alternative for solo attorneys.
You don't have an IT team to vet every vendor's data-handling. You need the privacy property out of the box.
Why solo attorneys pick Koaich
E2E encryption at every surface, no enterprise procurement, no KMS engineering.
How Koaich is different from WhatsApp Business
WhatsApp Business
- · Server-side encrypted (vendor holds keys)
- · Vendor can read your content
- · Recovery via vendor-held copy
- · Server-readable AI features
Koaich
- · End-to-end encrypted (you hold keys)
- · Vendor cannot read your content
- · Recovery via Shamir on your devices
- · Server-blind AI orchestration
Built for legal practice
Attorney-client privilege requires confidentiality you can demonstrate. Koaich's encryption boundary excludes the vendor — making the privilege claim defensible even when third parties seek access through us.
E2E encrypted client messaging
Every message between you and your client is encrypted on-device. Our servers see ciphertext.
Per-matter vault isolation
Each matter has its own encryption boundary. Your associate sees Matter A, your paralegal sees Matter B — there's no shared key that opens both.
Document encryption with per-recipient wrapping
Your co-counsel only sees the matters you've shared. Wrapping is by recipient, not by vault — granular without ceremony.
TTL-controlled retention
Messages can self-expire. The discovery footprint of long-ago drafts shrinks by default, not by retention policy debate.
