Every answer, with its proof
Knowledge deserves something better.
Your notes are trapped in someone else's app
Proprietary databases, closed formats, and syncs that disappear one day. Your knowledge should be yours, forever.
AI answers without proof
Assistants hallucinate, mix sources, and you can't verify where each claim came from. Without evidence, there's no trust.
Team knowledge stays siloed
Fragmented wikis, permissions impossible to revoke, and sensitive data exposed to third parties. Sharing shouldn't mean losing control.
Everything a second brain should be.
Markdown that's yours
Every note is a Markdown file on your disk. No lock-in, no closed formats. Open it, move it, or version it with tools you already use.
Verified context (grounded)
Every answer is anchored to your real sources, with citations and a groundedness score. If it's not proven, you'll know.
Local semantic graph
Akashi understands how your ideas connect and builds a knowledge graph on your own machine, without uploading anything to the cloud.
Encrypted team brain
Share an end-to-end encrypted vault with your team. Granular access, revocable instantly, with no data exposed to third parties.
AI with your own subscription (MCP)
Connect your favorite model via MCP using your own key. Akashi is the memory layer; you bring the AI. No middlemen.
Verifiable history (time-travel)
Every change is signed and chained. Travel back in time, compare versions, and restore with the certainty of a tamper-proof history.
From note to verifiable knowledge.
Write in Markdown
Take notes as always. Every idea is saved as a file you own on your disk.
Akashi indexes and connects
A local semantic graph and a signed history are built, all on your machine.
Connect your AI via MCP
Plug in your model with your own key. The AI reads your vault, you keep the control.
Ask and verify
Receive grounded answers with citations and a confidence score you can audit.
An encrypted, verifiable, revocable team brain.
Share knowledge without giving up control. End-to-end encryption, access you revoke in an instant, and a provable history.
End-to-end encryption
Content is encrypted on your device. Neither Apilium nor any third party can read your vault.
Instantly revocable access
Grant or revoke access per person. When revoked, keys rotate and the content becomes unreadable.
Verifiable by design
Every action is cryptographically signed. You can prove who changed what and when, beyond dispute.
Start free. Pay only when you grow.
The local app is yours and free forever. Paid plans add verifiable sync, encrypted team, and third-party verification. Purchased through the portal.

Common questions.
Do I truly own my notes?
Yes. Every note is a standard Markdown file on your disk. Open it with any editor, back it up, or leave Akashi whenever you want: your knowledge stays with you.
What does "verified context" mean?
Every AI answer is anchored to your real sources, with citations and a groundedness score. If a claim isn't backed by your notes, Akashi flags it rather than making things up.
Do I need to pay for AI separately?
Akashi is a pure memory layer: it doesn't include its own LLM. You connect your preferred model via MCP with your own subscription, so you use the AI you already pay for and keep control of your keys.
How does the encrypted team brain work?
You share an end-to-end encrypted vault. Access is granular and revocable: when you remove someone, keys rotate and they can no longer read the content. Nothing is exposed to third parties.
Which platforms does it support?
Akashi is available today for macOS (Apple Silicon and Intel), Windows, and Linux. Downloads always point to the latest published version.
Take control of your knowledge.
Local-first, encrypted, and verifiable. Your notes, your AI, your rules.
