Jace AI

Both Plus and Pro start with a 7-day free trial that can be cancelled at any time, according to the pricing page. The terms say that after a trial you may be charged unless you cancel, where the promotion said so, and that subscriptions then renew automatically each month or year. The public pages do not say whether a card is needed to start the trial.

Refund wording differs between pages. The site footer promises a 30-day money-back guarantee, while the terms say fees are generally non-refundable except at the company’s discretion or where law requires, and cancelling keeps access until the end of the paid period. Save the guarantee wording with your receipt if you plan to rely on it.

Signup runs through Google or Microsoft OAuth. The terms say the consent screen asks for permissions such as reading, composing, sending and managing email, and the getting-started guide lists syncing threads and labels, creating drafts and reading send-as settings and signatures. After connecting, Jace imports recent mail first and then up to 1 year of history on Plus or 3 years on Pro.

The terms state that copies of your emails are stored on Jace servers to allow fast processing and search. You can disconnect from Settings or revoke access in your Google or Microsoft account; the privacy policy says disconnecting starts deletion of the associated emails and derived data, although backups may persist for a limited time.

The privacy policy says drafts and summaries are generated by third-party AI providers such as OpenAI, Anthropic, Google Vertex AI or Azure AI, which receive the relevant thread content. Jace says these providers may use the data only to produce the requested output and not for training, and that Jace itself does not train models on your emails.

Two other flows are easy to miss. PostHog analytics tracks product use, and a marketing-partner clause says website cookies may be linked to other information about you, including your email address, for advertising, with an opt-out at retention.com. For client, legal or health correspondence, check whether your own obligations allow these processors before connecting the inbox.

The pricing FAQ says Jace never sends email without your approval and prepares drafts for you to review, edit and send. The security page adds a qualifier: it does not send emails without your action unless you explicitly ask it to. The terms describe sending a draft at your direction through your connected account.

Rules are where that line matters. The Rules FAQ lists auto-replies alongside CCs, templates and follow-ups, and follow-up drafts are prepared automatically when you are waiting on a reply. Read every rule before enabling it, and keep automated behaviour limited to drafting until you have reviewed a week of its output. Under the terms, you remain the author of anything sent.

Credits are the headline number, but the pricing page does not say how many credits a draft, label or chat request uses, so the allowance cannot be converted into emails. The account menu shows usage limits, according to the February 2026 changelog. The clearer differences are structural:

• Plus: 10,000 credits, 2 inboxes, 1 year of searchable history, standard support.
• Pro: 20,000 credits and higher tiers, 8 inboxes, 3 years of history, custom integrations and MCPs, priority support.
• Enterprise: usage-based pricing, setup help and an account manager.

Editorial assessment

One or two inboxes with ordinary reply volume fit Plus. Pro is justified by account count, older history or MCP connections rather than by the credit figure, which cannot be compared until per-action costs are published. Watch the usage display during the trial to estimate your own rate.

The changelog’s newest entry, dated July 1, 2026, describes features of Viktor, an AI employee product that the Jace homepage also promotes. The previous entry, February 2, 2026, is the most recent one about Jace itself and added daily email briefs, Pipedream Connect integrations and faster loading.

The Impressum lists Zeta AI, Inc. of Delaware as the provider, with a legal contact at viktor.com. The pages do not explain how the two products relate or whether Jace will keep receiving new features. For a tool with this much mailbox access, check the changelog again before committing to a yearly plan.

1. Note the plan, the connected account and the usage display before starting.
2. Wait for the import, then check which label each of the ten emails received.
3. Open the drafts for the three questions and the two meeting requests and check the facts and proposed times.
4. Confirm in the Sent folder that nothing was sent without your action.
5. Disconnect Jace and confirm that access is removed in the Google account permissions page.

Accept correct Needs Reply labels on the five actionable emails, drafts that answer only what was asked and an empty Sent folder. Reject invented facts, a sent message you did not approve or access that remains after disconnecting. No label accuracy or draft quality is reported until the exercise is run.
