Jace AI Review: Jace AI Pricing, Alternatives, and Where It Fits

How much does Jace AI cost?

Read off jace.ai/pricing: Plus is $25 per user per month, or $20 a month billed yearly ($240 a year, which the page shows as a $60 saving). It includes 10,000 credits a month, up to 2 connected inboxes, unlimited calendars and one year of searchable email history. Pro is $50 a month, or $40 billed yearly, with 20,000 credits, up to 8 inboxes, three years of history, custom integrations and MCP connections, and priority support. Pro can be bought with larger credit bundles, up to 2.4 million credits a month, at prices Jace does not list. Enterprise is usage-based and quoted.

Every paid plan starts with a 7-day trial and carries a 30-day money-back guarantee. Monthly credits reset at the start of each billing period and do not carry over; reward credits, which Jace hands out separately, never expire.

The number to check is inboxes, not credits. Plus connects two. If you run a personal address and a shared one, that is fine. If you also cover a departed colleague's mailbox, a client alias or a second company, you are on Pro. The same pattern decides Fyxer purchases, where Starter connects only one inbox; our Fyxer AI pricing breakdown shows how that plays out.

On credits, the pricing page states the allowance but not what one credit buys, and we did not find a per-action rate in Jace's public docs. For a normal inbox, 10,000 a month is unlikely to be the constraint. If you plan heavy history searches or custom workflows, run the trial on your real mailbox and read the usage figure under Settings, then Billing and usage, before the trial ends.

What Jace costs for a team, worked through

Jace is billed per user, so the bill scales with headcount. Here are the list prices at three common sizes, next to ours, so you can see where each product is the cheaper buy.

• One person. Jace Plus costs $240 a year. Officeagent Assistant costs $119 a month billed yearly, $1,428 a year. For one person who only wants email handled, Jace is roughly six times cheaper, and it is the sensible purchase.
• Five people. Jace Plus costs $100 a month billed yearly, or $200 on Pro. Officeagent Office costs $319 a month billed yearly for up to ten people. Jace is still cheaper on price alone.
• Ten people who need a third mailbox each, or shared inboxes. Jace Pro costs $400 a month billed yearly. Officeagent Office is $319. This is roughly where the prices cross, and only if the team also wants the work beyond email that Jace does not do.

The seat rule to know before you invite your team

Jace's team setup guide is unusually clear about this, and it is worth reading before you roll it out. As soon as you send an invite, Jace adds a paid seat for that person, whether or not they ever accept. The confirmation dialog tells you so (the button reads "Invite & add seat"). An invite nobody accepts expires after 7 days, and revoking one earlier gives a prorated credit on your next invoice, handled by Stripe.

That is fair billing, but it changes how you should run a pilot. Do not invite the whole office on day one to see who uses it. Invite the three people who live in email, run them for two weeks, and add seats once you know the drafts are being sent. The guide also shows how team pricing works with a worked example of a $65 seat; that is an illustration of the proration math, and the public pricing page lists no Team price, so ask Jace for a quote if you are buying for a group.

Is Jace AI safe?

Jace states that it has completed a SOC 2 Type 1 examination, independently audited for security, availability and confidentiality, holds CASA Tier 3 compliance (the security assessment Google requires of apps that read Gmail data), encrypts email in transit and at rest, and never trains AI models on your data. For most small businesses that is a reasonable baseline.

The detail that matters for some buyers is the report type. A Type 1 report checks that controls are designed properly at a single point in time. A Type 2 report tests that they actually operated over a period, usually three to twelve months. If your own clients, an insurer or a vendor questionnaire requires Type 2 from every tool that touches client email, ask Jace for its current report before you connect a work inbox. Many vendors complete Type 1 first and Type 2 later, so the answer may have changed since we checked.

Behavior is the other half of safety. By default Jace does not send anything: it prepares drafts and you send them. Auto-send exists, but it is opt-in per label, switched on under Settings, then Labels, with warnings before you enable it. That is a sensible design. It also means one person's settings, not company policy, decide whether an AI is sending mail under your name, which an office with compliance obligations should decide on purpose.

Does Jace AI work with Outlook?

Yes. Jace's documentation says it runs on top of Outlook, covering Microsoft 365 and Outlook.com accounts. Your existing folders and categories are imported and kept in sync, your default from address and signature carry over, Outlook rules keep running in Outlook, and drafts Jace writes appear as normal Outlook drafts you review and send. It connects Gmail the same way.

There is no native Jace mobile app yet. Jace's own docs say iOS and Android apps are on the roadmap, and in the meantime you use the Gmail or Outlook app on your phone, where Jace's labels and drafts show up because they live in your real mailbox. For most people that works fine. If your team triages mainly on phones, try it for a week before you commit.

What Jace does better than we do

Price, first. For email alone, Jace is far cheaper than Officeagent at every team size under about ten people, and the drafting quality is the reason people buy it. If your problem is purely a full inbox, Jace or a close rival is the rational purchase and we would rather tell you that here than lose you after a refund.

Jace also goes deeper on the inbox itself. Chatting across three years of email history, natural-language rules that trigger on specific senders, custom integrations and MCP connections on Pro, and opt-in auto-send for routine replies are all things a dedicated email product should do better than a broader office assistant, and it does.

Where Jace and Officeagent actually differ

Jace answers email. Officeagent runs the office work that email kicks off. Take a message most small firms get every week: a client asks to move Thursday's call, wants the signed engagement letter, and reminds you their W-9 is attached. Jace drafts an excellent reply. Officeagent drafts the reply, books the new time on the calendar, files the W-9 where the team keeps vendor paperwork, logs the task and keeps chasing the signed letter until it arrives. Everything outgoing waits for one-click approval, and there is no auto-send setting to switch on.

Meetings are the second gap. Jace does not list a meeting notetaker. Officeagent writes up meetings with the summary, decisions and action items, and turns the action items into tracked tasks. See how meeting summaries work, how follow-ups are chased to completion and how documents are filed.

Billing differs too. Jace charges per user and meters AI credits. Officeagent charges one flat price per office ($149 for one person, $399 for up to ten, about 20 percent less yearly) with an allowance of 300 or 2,000 agent actions a month, counted only when you approve a finished piece of work, so drafting and redrafting cost nothing and there is never an overage invoice. The full plan list is on our pricing page.

What is the best Jace AI alternative?

It depends which part of Jace you were buying. Every price below comes from the vendor.

If you want the closest like-for-like email assistant with meeting notes included, Fyxer costs $30 per seat per month on Starter and $50 on Professional, and it adds a meeting notetaker Jace does not have. Watch its one-inbox Starter limit. Our Fyxer AI review covers the seat traps. Serif is the other option in that shape, $30 a month on Lite with a recorder, task tracker and a SOC 2 Type 2 report; our Serif AI review explains its undefined usage multiplier and its two-product split.

If you want a faster email client rather than an assistant inside your current one, Superhuman and Shortwave replace the inbox itself. See Superhuman compared and Shortwave compared.

If you want an assistant that reaches far beyond email and someone on your team enjoys building automations, Lindy connects to more than 1,000 tools and meters usage in a shared credit pool. Our Lindy AI review explains the credit rules.

If you want the full field side by side, the best AI email assistant comparison prices Gemini, Copilot, Fyxer, Superhuman, Shortwave and Missive against each other, and email management software for teams covers shared-inbox tools such as Front and Help Scout.

If the inbox is only the front door to the work, and you want meetings, filing, spreadsheets and follow-ups handled with human approval on every outgoing step, that is Officeagent.

Who should buy Jace, and who should not

Jace is a good purchase if most of these describe you.

• Your bottleneck is replying to email, not the admin work that follows it.
• You are one to five people, where $20 to $25 per user is hard to beat.
• You work in Gmail or Outlook on a desktop browser most of the day.
• You want drafts in your own voice with almost no setup, and occasionally a rule or two.
• A SOC 2 Type 1 report satisfies your clients, or you have confirmed Jace's current report type.

Reasons to look elsewhere

Skip Jace, or pair it with something else, if any of these are true. A bigger Jace plan will not fix them.

• You need meetings recorded and written up with action items, which Jace does not list.
• The work after the email, filing documents, updating a tracker, chasing a signature, is what actually eats your week.
• Your contracts require a SOC 2 Type 2 report from every tool that reads client email, and Jace cannot yet provide one.
• Company policy is that nothing goes out without a human approving it, and you would rather not rely on each user leaving auto-send off.
• Most of your triage happens on phones and you want a native mobile app today.
