PRODUCT DETAIL

ARC Synapse

For teams or individuals — gather scattered records and get sourced answers the moment you ask

Pile up your records, ask in plain language, get answers grounded in sources.

As records flow in from Slack, Outline, AI sessions, or direct input, Synapse searches by keyword and meaning, compares across time, and answers — a quick summary or a 'what changed from A to B' history, always with sources. Bring your own AI (OpenAI, Claude, Gemini); every workspace is fully isolated, for teams and individuals alike. And connect a production database to answer straight from live data at ask time — no import.

FAQ

Frequently asked questions

How do I add records?

Type directly, or let an AI session auto-ingest via API key. Connect Slack/Outline to pull in existing conversations and docs.

How does it answer?

It finds relevant records via keyword and semantic (embedding) search, compares across time, and shows the source records behind each answer.

Can I use it in Slack?

Yes. 'Add to Slack' once to pull channel conversations as records, then mention the bot in a channel to ask right there.

Which AI does it use?

Connect your own OpenAI, Claude or Gemini key (BYOK). Even without a key, you can try it with the built-in AI.

Can individuals use it?

Yes. Beyond team knowledge, an individual can build a remembering 'second brain' from their own records.

Is data isolated?

All data is fully isolated per workspace and never mixed with other workspaces.

How much does it cost?

Three plans: Team (₩39,000/mo), Business (₩99,000/mo), and Enterprise (contact us).

Can I connect our database and ask about it?

Yes. Connect a PostgreSQL-compatible database (Cloud SQL, RDS, Supabase, Neon, self-hosted) and Synapse answers with read-only queries run at ask time — no import. Multiple sources per workspace.
