How tentus works, in plain language.

Sign in with your work email. Your workspace is created on first sign-in, and you can rename it from settings anytime. One workspace per account is the default.

Shared workspaces are on the roadmap. Today, each workspace is single-player, so what Lumi surfaces stays sharply personal.

Connect a calendar and one note source. Within a day Lumi will start preparing you for meetings and raising what’s worth a second look. The more you capture, the more useful that gets.

Press ⌘N from anywhere in the app. The capture pane opens with the cursor in the title field. Save is automatic.

The web clipper saves any page as a source with full text, title, and original URL. Once captured, the page is searchable and available to Lumi.

Voice captures are transcribed in the background. The original audio is kept alongside the transcript so you can replay anything. Lumi reads the transcript, not the audio.

PDFs, plain text, Markdown, common image formats, and audio. Each captured file becomes a source with extracted text and metadata.

Lumi only knows what you’ve told it. It reads across the sources in your workspace and connected accounts, and it cites them whenever it surfaces something.

No. Your workspace is private. Lumi’s reasoning runs through our LLM providers under data-processing agreements that exclude training on customer content.

Open Lumi home, or press ⌘K from anywhere. Ask in plain language. Lumi replies with sources cited inline.

Lumi may not have retrieved enough supporting material. Check that the relevant source was saved and processed, then try a more specific question. An unanswered question does not prove that the information is absent, and a confident answer still needs checking against its sources.

Yes. Tell Lumi “add 10 min buffer before meetings” or “block lunch 12-1pm” and scheduling uses it when proposing habits or tasks — buffer time around events and protected lunch windows are enforced automatically. Travel-time preferences can be saved, but location-aware travel blocking is not yet applied because the scheduler does not receive event-location metadata.

Lumi Agents describe preparation and triggered workflows. They depend on the required connections, settings and access. Email digests require opt-in; tagged-note workflows must be enabled before a matching note can trigger them. A notes-to-actions workflow can create tasks without a separate approval for each task, so review the result. Check the prerequisites and fictional examples at tentus.io/agents.

Today looks for the next timed event within 18 hours on a connected calendar and builds a brief from selected workspace excerpts. A cached brief can be up to six hours old. Open the sources to check names, commitments and dates. Email preparation requires the email-digest opt-in and successful delivery; a connected calendar alone does not guarantee an email.

Lumi watches for things worth raising — a note that contradicts something you wrote months ago, a commitment you made and haven’t acted on, a pattern across recent captures — and surfaces them on Today. Dismiss anything you don’t want and it won’t come back.

Proactive features use scheduled checks of supported, available material and can return no suggestions. Connection, processing and delivery failures can leave gaps. Review the suggestions on Today; the daily email digest is a separate opt-in. We have not established an interruption rate or guaranteed scan latency.

The catalog lists Google Drive, Microsoft 365, Slack, Fireflies, Granola, Zoom, Zotero, GitHub, Figma, Linear, Readwise, and RSS feeds. Google Calendar needs its own connection and appears in settings when enabled. We are testing availability before opening access; see the integrations catalog for the described connectors.

Settings → Integrations → Disconnect. The connection is severed immediately and we delete the stored credentials within twenty-four hours.

Each connector requests its own scopes. Most source connections read content, but Microsoft calendar event actions use Calendars.ReadWrite and Slack requests chat:write for explicit posting actions. Review the provider consent screen before connecting. A granted scope does not itself confirm an action; Lumi asks you to review outbound actions when they are available.

Settings → Billing. Upgrades are immediate, cancellations take effect at the end of the current billing period, and your workspace stays intact either way.

Within the first fourteen days of a new subscription, yes. Email hello@tentus.io and we’ll process it the same day.

Yes. Free covers 50 notes a month, up to three connected integrations, unlimited questions to Lumi, and the daily digest. Pro is for people whose second brain is paying for itself.
