ἀλήθεια · your knowledge, revealed

MCP First
Knowledge Management.

Everything you capture — meetings, notes, research, half-formed ideas — lands in one place, organized for you. Then ask it anything and get a real answer, with the sources to back it up. And the AI assistant you already use? It plugs straight in.

aletheia · your library
Aletheia's library: everything you've captured in one organized, searchable table — titles, topics, dates, and where each note came from.

everything in one place — organized, connected, and ready to ask

the problem

You capture everything.
You use almost none of it.

The notes pile up faster than anyone can read them — and the moment you need something back, it's gone.

01

The pile keeps growing

Every meeting, call, and idea gets captured somewhere. Going back to actually re-read it? That happens roughly never.

02

Your AI has amnesia

You explain the same background to your assistant over and over. It never remembers what you told it last week — or what's in your notes at all.

03

Search finds files, not answers

Keyword search hands you a list of documents to dig through. What you actually wanted was the answer.

Aletheia is the layer that fixes this. You capture; it organizes, connects, and remembers — then hands the whole thing to your AI so you can just ask.

ask anything

Ask your notes anything.
Get an answer you can trust.

Ask a real question in plain English. Aletheia reads across everything you've captured and answers — with links to the exact notes it used.

Aletheia answering a question about a project's status, with a clear summary of blockers, owners, and next steps — each point linked back to the note it came from.

Every claim links back to the exact note it came from, so you can verify in one click. And if the answer genuinely isn't in your notes, Aletheia tells you — it won't make one up.

status

"What's the status of the Orion rollout?"

A clear rundown of where things stand — decisions made, what's blocking, who owns what, and what's next.

recall

"What did we decide about pricing?"

The decision, when it was made, and the conversation behind it — pulled from wherever it actually happened.

connections

"Show me everything about Acme."

The people, projects, meetings, and open questions tied to any person, company, or topic in your notes.

your plate

"What's on my plate this week?"

Every open commitment and follow-up, gathered from across your notes and grouped so nothing slips.

timeline

"Build a timeline of the pricing debate."

The whole story in order, beat by beat — each moment linked to the note where it happened.

the honest one

"Where do my notes contradict each other?"

The one nothing else does: conflicting statements surfaced side by side, so you catch what changed.

what it does

Everything you capture,
finally usable.

Real screenshots from the app — not mockups. This is what you'd be working in.

find

Find it by meaning, not keywords

Half-remember something from a call months ago? Just describe it — Aletheia finds it even when you don't recall the exact words. Narrow by date, project, or person the moment you need to.

connect

See how everything connects

Aletheia quietly maps the people, projects, and threads running through your notes. Sketch a diagram right inside a note, and follow the web of connections it builds for you — no manual linking required.

personalize

Make it feel like yours

Seven built-in looks, from calm near-black to warm paper to a phosphor-green terminal. Tune any of them, or build your own — because you'll be living in this every day.

your ai

Works with the AI
you already use.

Aletheia speaks MCP — the open standard that lets AI assistants connect to your tools. Point yours at your workspace and it just works.

01

No more copy-paste

Connect Claude — or any assistant that speaks MCP — and it reads your notes, answers from them, and can even write new ones for you. No pasting snippets, no re-explaining context.

02

Your AI, your call

Use whichever assistant you prefer, and switch whenever you like. Your knowledge doesn't move and doesn't get locked to one vendor — it stays yours.

03

Or use the built-in one

Don't want to bring your own? A capable assistant is built right in, ready to answer from your notes the moment you open the app.

your data

Your knowledge
stays yours.

Easy to fill, safe to trust, and never held hostage.

Nothing gets lost

Every change is saved and reversible. Delete something by accident? Bring it right back.

Bring it all in

Import your existing notes, forward meeting transcripts by email, or paste anything — it all lands in one place.

Take it anywhere

Export everything as plain, open files whenever you want. No lock-in, not ever.

It's private

Your workspace is yours alone. Your notes aren't anyone's training data.

where this stands

Not open to the public yet.

Honest status: Aletheia is being built in the open, and it isn't ready for everyone quite yet.

In active development

Aletheia runs every day against a real, messy knowledge base — but it isn't packaged for other people yet. That's why there's no sign-up or download here: it's deliberate, not missing.
