AI knowledge base for experts managing multiple clients and projects

Knowledge lost across clients and projects.
Sofie writes and links the wiki for you.

For anyone managing multiple clients, projects, or teams: chat in plain language and Sofie writes the pages, cross-links related entries, and keeps every knowledge domain current.

0 min

1 wiki

instead of scattered folders, Slack threads, and docs across apps.

seconds

to an answer from your wiki, not another question to the founder.

Expected outcomes, not customer-reported metrics.

For multi-domain experts and client-facing teams

Manage multiple knowledge domains without losing the details. Each client, project, or workstream gets its own organized pages, deadlines, and history, without you writing or linking a page by hand.

See how it works

Find clauses and links across five client folders in one chat.

Reminders tied to the right client page, days before each deadline.

Turn one client's work into a template you scaffold for the next.

Log call outcomes straight into the client's history from chat.

Tell Sofie what each folder is for; it builds and links the pages.

When your practice grows into a team

The same wiki scales to a shared workspace when you add collaborators: onboarding, decision history, and procedures stay current without anyone babysitting them.

See how it works for small teams

A few examples of what the same wiki handles once a team is on it.

Capture repeat questions once so new hires self-serve.

One starting page with architecture, pipeline, and style guide.

Recover the full reasoning behind any past decision.

Keep process docs current as the team doubles, old versions kept.

Turn a Slack thread into a structured procedure page.

Document once so other teams stop interrupting.

"It's not that we document better. It's that we finally document at all."

How it works

Three steps. Chat in, wiki out. No templates, no copy-paste, no wikis to babysit.

Ask in chat

Write like you'd talk to a colleague. No forms, no prompt magic, no templates to fill in.

AI updates the wiki

The right page is created or edited automatically. Related entries get cross-linked. Nothing to copy-paste.

What you can do with your AI knowledge base

Natural AI chat

Interact like in a real conversation. No prompt engineering. Answers stream in live.

Automatic updates

The chat writes and edits wiki entries. No copy-paste needed.

Familiar interface

Wikipedia style, with table of contents, hyperlinks, and categories.

Semantic search

Ask in your own words and get the right page back. Search matches meaning, not just keywords, so “Rome trip” surfaces a page titled “Italy vacation notes”.

Versioning and history

Every change is tracked. Go back whenever you want.

Files always in context

Every file lives on the page it belongs to. Move unfiled uploads to the right document in a click, and the AI reads them when you ask.

Reminders on wiki pages

Ask the AI in chat to remind you about a page, or add one by hand. Each reminder is bound to a wiki page and fires on time, with optional Telegram delivery.

Public page sharing

Share a page and all its subpages with anyone via a link. Read-only, no login needed. Rotate or revoke the link anytime.

Tool functions settings

Choose which tools the AI can call. Toggle search, reminders, clarifying questions, and more from Settings, no prompt engineering.

Voice transcription in chat

Tap the mic, speak, and the transcript appears in the input box. With a configurable preferred language for better accuracy on short utterances.

Notion integration

Connect your Notion workspace via MCP. The AI searches, reads, creates, and updates Notion pages from the same chat that manages your wiki.

What makes it different

Unlike Notion, where you create and link every page by hand, and Google Drive, which has no structure or AI, Sofie keeps the wiki current on its own. Three things that set it apart when your brain holds more knowledge than your tools.

Automatic cross-linking

Related pages link themselves. In Notion you link pages by hand. Google Drive has no structure at all.

Wikipedia-style reading

Clean articles with a table of contents, not nested blocks or an editor you have to tame.

AI included, or bring your own

A built-in AI assistant works out of the box with usage limits, or add your own API key for no limits. Switch to ChatGPT, Gemini, or a custom endpoint anytime.
