How Much Does Jace AI Cost Per Month?

How much Jace AI costs per month depends less on which tier you pick than most pricing pages let on. Jace sells two self-serve plans plus a quoted enterprise option, and each one sits on top of a monthly credit allowance that resets with your billing period. The tier sets your floor. The meter decides what you actually pay.

That matters because Jace is not sold as an email tool. It is sold as an executive assistant that starts with your inbox and reaches into your calendar, your integrations and a chat layer over your mail. So the useful question is not whether the sticker looks high for email software. It is how much of that surface area you will genuinely use.

This page splits the price along that line, using what Jace publishes on its own pages as of August 2026.

The short answer: what Jace AI costs per month#

Jace publishes two self-serve monthly tiers — Plus and Pro — and an Enterprise plan quoted on request. Both self-serve tiers carry a 7-day free trial you can cancel any time inside the week. Both also offer yearly billing, which lowers the effective monthly rate.

We do not reprint competitor prices here — they move, and a stale figure is worse than no figure. The current number for each tier is on Jace's pricing page, and on the day you buy that is the only source worth trusting.

More stable, and more useful, is the packaging shape. Jace's self-serve plans are priced per account with a cap on connected inboxes rather than per seat, and calendars are uncapped on both. Rollouts where several people each need their own login are what the Enterprise quote exists for.

The part that catches buyers out is the credit allowance. Every plan carries a monthly credit balance that resets at the start of each billing period, and the higher tier can be raised to much larger ceilings at pricing that varies. The monthly figure is a starting point, not a cap.

What each Jace plan unlocks for email#

The two self-serve tiers are not a feature ladder in the usual sense. Almost everything the assistant does for email is present on the entry plan: drafts prepared before you open the inbox, automatic labelling and categorisation, bulk organising, and a chat layer you can question.

What changes as you move up is scope — how many inboxes you can connect, how far back the assistant can see, and how much work you can push through it in a month.

The history limit is the one worth understanding, because it is a quality gate wearing a storage limit's clothes. Jace's own sync documentation says the first import covers roughly the last 45 days of important mail, then expands to a year on Plus and up to three years on Pro. An assistant that can reach one year of your correspondence drafts a different reply to a returning client than one that can reach three.

The criteria that actually decide the bill#

Most Jace pricing comparisons stop at the tier list. That is the least decision-relevant part, because both tiers do the same job and the gap between them is capacity. Whether the monthly cost is money well spent turns on a different set of questions. Run these seven before you look at any number.

• Floor or price? A credit meter puts a variable in your bill. Ask what a heavy month looks like, not an average one.
• Inbox cap. The connected-inbox limit usually forces the upgrade long before the credit allowance does — a founder with a personal address, a company address and a shared alias is already at the entry tier's ceiling.
• Context depth. How much mail history the assistant can search separates a specific draft from a generic one, and it is tier-gated rather than usage-gated.
• Surface area. You buy calendar handling, integrations and a chat assistant alongside the inbox work. If you only want triage and drafting, part of the price is capability you will never open.
• Control before send. Whether drafts wait for you, whether an action can be reversed, and whether anything records what the assistant did.
• Switching cost. A layer that drafts into the Gmail or Outlook you already use costs nothing in habit. A replacement client costs you a migration.
• Data handling. Retention, and whether your mail trains anything. Take this from the terms, not a marketing page.

Scoring Jace against an email-only assistant#

Scored against a tool that only does email, Jace's monthly cost buys more and asks you to forecast more. Neither is automatically the better deal. The column that matters most below is the last one — where you can check the answer yourself instead of taking a review's word for it. Score each row for your own situation first, because a cheaper tool that caps you at one inbox is not cheaper.

A worked example: one founder, two inboxes#

Take a solo founder with a personal address and a company address, roughly 120 inbound messages a day — mostly triage and short replies, plus a handful of longer responses that need context from a thread six months old.

1. 1

   Start at the entry tier, not the one you think you need

   Two connected inboxes fits inside the entry tier's cap. Do not pay for headroom you have not measured.

2. 2

   Spend the trial metering, not evaluating

   Seven days is enough to learn your credit burn if you use it like a normal week. Push normal volume through it, including one heavy day, and watch the balance.

3. 3

   Extrapolate the heavy day, not the average

   Multiply your busiest day across the month rather than your median one. Budgeting from an average is how a metered tool surprises you in month two.

4. 4

   Price the history gate separately

   If your longer replies routinely need a thread older than a year, the entry tier will draft them thinner and no credit top-up fixes that. It is a tier decision, not a usage one.

5. 5

   Decide the annual commit last

   The yearly discount is real, but it prices twelve months of a usage pattern you have known for seven days. Run one month on monthly billing first.

Red flags to check before you commit#

None of these are accusations. They are where a metered, bundled assistant most often costs more than the buyer planned for.

• The consumption schedule is not published. On the pages we checked in August 2026 — the pricing page and the public docs — Jace states a credit allowance per tier but no per-action table of what a draft, a summary or a bulk organise costs. That is common in the category rather than sinister, but it makes the trial your only route to your own burn rate.
• Time-saved figures are self-reported. Every tool here publishes one. Test it during the trial week; do not budget from it.
• An annual discount buys a year of a usage pattern you have known for a week.
• The inbox cap and the credit allowance move independently. You can sit well inside one and be blocked by the other.
• Bundled surface area is only value once you open it. Integrations you never configure are cost with no return.

What we'd pick, and who should stay with Jace#

If your inbox needs an assistant and your calendar, your tickets and your documents need one too, Jace is the coherent purchase. The monthly cost is spread across all of it, and judged that way it is not really an email price. Buy it as an assistant, use the trial to measure the meter, and start on the tier your inbox count requires.

There is a second, sharper reason to pick Jace, and we will name it because it is the dimension where we lose. Jace writes drafts into the Gmail or Outlook you already use. You keep your client, your shortcuts and your team's existing setup, and the assistant shows up inside them. AI Emaily is a mail client, so choosing us means moving where you read your mail. For plenty of people that switch is the entire objection, and no feature list on our side makes it free. If you will not change clients, stop reading and take the layer.

Where we think the money goes further is when what you actually want is control over what the assistant does, at a price you can forecast. We build AI Emaily, so weigh the next two paragraphs accordingly. Our billing has no credit meter to model — you pick a plan and that is the bill — and the trial is seven days on Pro with a card required and nothing charged if you cancel before day seven. There is no permanent free tier, and we would rather say so here than let you discover it at checkout.

The substantive difference is the control layer. Drafts wait for approval before anything sends, actions can be undone, and an audit record shows what the agent did and why. Voice comes from a Personal Context brain you write and per-client profiles you set, not from anything scraped out of your sent mail, and we do not train on your mail. We connect Gmail, Outlook and plain IMAP, which matters if one of your addresses lives on neither of the big two.

The honest scope: if you want one tool running your whole operating stack, we are the narrower product. If you want the inbox itself to work properly, with approval, undo and an audit trail as defaults rather than settings, that is what we built. Current plans are on our pricing page.
