Jace drafts your email. Orca answers for your whole desk.
Jace belongs to the new wave of AI email assistants: it reads your inbox, triages, and produces drafts you would plausibly send. Orca agrees that is the right starting point, and then treats it as roughly a quarter of the job. The rest is the diary, the meetings, the bookings and the follow-through.
The short version
If you want AI drafts in a personal inbox with minimal setup, Jace is a light way to get them.
If the emails are one limb of the problem, and the meetings they generate, the promises they contain and the diary they fight over are the others, Orca operates all of it under one approval queue.

A good draft is not a finished job
An email assistant succeeds when the draft is sendable. An assistant succeeds when the thread is resolved. Those are different finish lines. When a client writes "can we move Thursday?", a sendable draft says "of course, what suits?". Orca checks the diary, moves the actual invite for every attendee, and confirms the new time, because it has a scheduling engine and calendar control behind the drafting model.
The same distinction runs through the whole product. Commitments in email become tracked items, not just well-phrased acknowledgements. Meeting requests become booked meetings. The out-of-office answers people from your shared history and files the rest for your return.
Beyond the inbox entirely
Some of the most valuable work never generates an email at all. Orca prepares a brief before every external meeting, drafts the follow-up from the call transcript afterwards, maintains relationship warmth across channels, drafts LinkedIn content from your actual work and produces documents from your own data. An email-only assistant has no surface for any of that.
Orca Booking adds the public-facing half: booking pages with meeting types, intake questions and branded confirmations, so the "grab time with me" link on your signature is your assistant too.
Bespoke and private by design
Orca runs as a desktop app against your own private database. Mail, transcripts and relationship data stay on infrastructure that is yours, which matters to the lawyers, accountants and founders it is built for. Hosted email assistants ask you to trust their cloud with the most sensitive data you have.
It is also set up by a human, around your accounts, your tone and your rules. That managed model costs more than a self-serve subscription, and buys a system that fits on day one.
When Jace is the right answer
Sometimes it is, and pretending otherwise would be dishonest. If the list below describes the job, Jace may be all you need.

A hosted service reading your mail is acceptable risk
A note on which Orca this page is about
Orca’s full product is a managed service: a desktop AI Chief of Staff set up around you by a human, running on your own infrastructure, priced monthly for professionals whose time justifies it. That is the product compared on this page.
There is also a lighter £79/month web-only tier. It is a good product, but it does not include Orca Booking, out-of-office mode or several other features in the table above. If you are comparing against the tools on this page, compare against the full version, then see pricing for both.
Questions people ask
Is Orca a Jace alternative?
For AI email triage and drafting, yes, that surface is common to both. Orca extends it with scheduling that books real meetings, public booking pages, contextual out-of-office, pre-meeting briefs, transcript-driven follow-ups and relationship memory, run from your own infrastructure.
Does Orca write better drafts than Jace?
Orca’s drafts are grounded in more than the thread: your full history with the sender, call transcripts, open commitments and your configured tone. Whether any given draft is better is for you to judge on a demo; the structural difference is the context behind it.
Can Orca book meetings, not just draft about them?
Yes. It reads the request in the thread, checks every connected calendar, proposes times with one-click booking buttons or accepts the other side’s suggestion, and creates the invite when you approve. Reschedules move the existing event.
What does Orca cost compared to Jace?
Jace is a per-seat subscription. Orca’s full product is a managed monthly service; see the pricing page for current numbers. The £79/month web tier exists but lacks booking pages and out-of-office; this page compares the full desktop product.
Who is Orca actually for?
Founders, partners and senior professionals whose inbox and diary are the bottleneck, and whose hourly value makes a managed assistant obviously worthwhile. If that is not yet you, a lighter tool is the honest recommendation.
