Stop paying to rediscover what you already know

Your team loses a day a week re-finding what someone already figured out.

One self-updating, bi-temporal, permission-aware memory across every tool — every answer cited and scoped to who can see it.

the problem

Your company knows the answer. Finding it is the problem.

Knowledge is scattered across a dozen tools, half of it is out of date, and the person who knew it left in March. Everyone pays for it — every day.

Hours lost searching
The same questions, asked and re-answered across Slack, email, and docs.
Slow onboarding
New hires interrupt your best people just to get oriented.
Stale decisions
Teams act on information that quietly went out of date.
Knowledge walks out
When people leave, their context leaves with them.

capabilities

Everything a wiki can't do.

The strongest surfaces over one permission-aware graph — browsable, point-in-time, always cited. Try them right here — interactive, no login.

Ask anything, with sources

Answers you can trust, because they cite themselves.

Ask in plain language and get a grounded answer with its sources — never a confident guess. If you're not allowed to see a source, it never reaches the answer.

01 / askGrounded answers, cited
Bi-temporal memory

Ask what you knew last quarter — not just today.

slashh remembers how your knowledge changed over time, so you can replay any decision and answer point-in-time questions. The one thing search and wikis can't do.

Permission-aware, fail-closed

The same page shows only what you're allowed to see.

Every answer respects source-level permissions by default. Two people ask the same question and each sees exactly — and only — what they should.

meet wikky

You won't have a wiki. You'll have Wikky.

Wikky is your company's context-aware wiki — and your assistant. Ask it anything about your company and get a cited, permission-aware answer in plain language. Nothing to maintain: feed Wikky whatever you want and it just knows.

  • Ask anything. Plain-language answers, always cited — never a confident guess.
  • Context-aware. It knows your projects, people, decisions, and how they changed over time.
  • Feed it whatever you want. Docs, threads, tickets, files — folded into one living memory.
  • Permission-aware. Everyone gets answers scoped to exactly what they're allowed to see.

What does billing depend on?

Billing runs on the Payments service (Stripe webhooks) and the Accounts graph for entitlements. The Platform team owns it.

Onboard without interrupting anyone

A new hire asks in plain language and gets a cited, step-by-step answer pulled only from sources they're cleared to see — then finds the real owner of any system by activity. Productive in days, without pinging your seniors.

why us

Three things only we do.

Bi-temporal, permission-aware, and open & self-hostable. Here's the honest gap versus enterprise search, wikis, and a DIY git-repo "brain."

the thesis
“A wiki goes stale the moment it's written. The answer your company needs already exists in Slack, a doc, a decision someone made in March — scattered and out of date. We built one memory that stays alive, knows who's allowed to see what, and can tell you what was true at any point in time.”

FAQ

The questions a CTO actually asks.

Search finds documents; slashh answers questions with cited sources, remembers how knowledge changed over time (bi-temporal), and surfaces contradictions. It's a memory, not a search box.

Every answer is grounded in your sources and cited. If the brain can't support a claim from a source you're allowed to see, it says so instead of guessing.

Permissions are fail-closed and enforced at the source level. The same question returns different answers to different people — each scoped to exactly what they're allowed to see.

Connect a source read-only and you're answering questions in minutes. No migration, no re-platforming.

Only if you let it. Self-host or run air-gapped, and bring your own model so nothing is sent anywhere you don't approve.

No. The core is open-source, self-hostable, and exports your graph (OKF). Your knowledge stays yours.

Stop rediscovering what your company already knows.

Connect one source and see the difference this afternoon.
