Jace AIReviews of jace.ai

I forgot to cancel my free trial and was charged for a full annual subscription; entirely my own mistake, and I was well past the formal refund window. I wrote to support hoping for some goodwill and honestly expected nothing. Instead, they responded quickly, looked into my account properly, explained the situation clearly, and refunded everything except the one month I had actually used. No arguing, no hoops to jump through, no endless back-and-forth. You learn the most about a company when something goes wrong, and Jace handled it better than I thought possible. Five stars, fully deserved. Rebecca

Jace is amazing. I tried shortwave, gemini, superhuman, along with writing my own script for claude. Nothing worked and they would hallucinate and give wrong information. A major issue I had with ALL of them except Jace is that they would ignore critical rules I had set (i.e. NEVER ASSUME anything when drafting a customer reply, ask me first). Jace is already saving me time and now that I set it up properly with the right rules it is working very very well. Claude, Gemini, and ChatGPT all said Jace would have the same issues as shortwave but I assure you this is NOT the case. Much more reliable. My one complaint is the expense... you get around 10k credits for $25 and you can burn through those pretty quickly when drafting quotes for customers (500-1k credits for one email depending on complexity). Also setting it up and getting it tuned takes about 20k credits total. They give you 10k on the trial which was nice though and when I had a glitch on the backend with credits Jace support got with me later that same day and fixed it.

I have never sounded so professional. Jace remembers the history and relationships before drafting responses that sound just like I wrote them. I'm often impressed by its attention to detail and its ability to bring up details that I had, quite frankly, forgotten or overlooked. Additionally, it drafts friendly but professional-sounding follow-up reminders to important email threads that go unanswered, which helps keep me on track. Highly recommended.

The reviews trend tells you all you need to know: Was great, now NOT WORTH IT...total bait and switch. When I started it was $20/month and you could use it to help draft emails, auto draft replies ready for me to tweak and send, make recommendations on situations and responses, it read emails to gather aggregate information providing a very simple layout. It learned my style. I used it daily. Then they changed the pricing model to use credits (Feb/Mar26), and for the same $20 you get 10000 credits and I burned through them in 3 days (even being very mindful). A Simple question like "What was the link that allowed me to xxxx" can eat 600-800 credits. I tried 2 more months, but even using Jace less than 5% of what I did previously, I still run out of credits. They advised me to not use featured tools like auto-drafting or chat so as to preserve credits (not a lot of benefit left after that). These features burn far too many credits in the background without ANY interaction. I have to abstain 5 days at a time to preserve credits and still run out before 30 days. Even If I paid double for 20000 credits, Id have to use it at around 10% capacity and likely run out. Its a great tool to use. I have a lot of good things to say about how the solution works. But far overshadowed by the inability to use the main features...not worth it. You cant use it...

They switched their billing system to a credit model out of nowhere and now it's unreasonably expensive. Will build this out elsewhere.

Jace is genuinely an excellent tool. The product itself works very well and has been valuable for my workflow, which makes this situation even more disappointing. I subscribed for a full year based on a pricing model built around a specific number of emails per month. Mid-subscription, that model was changed to a credit-based system. In practice, the new limits feel extremely low and will almost certainly cost me more than what I originally agreed to when I signed up. I raised my concerns with customer support, but the response was essentially that no changes would be made. My frustration is not with the quality of the tool... it is strong. It is with changing the commercial terms during an active annual subscription. That creates a real sense of distrust and disappointment. Great product, but this pricing change has seriously damaged my confidence.

Been on Jace Pro for about five months. 126+ rules, 4 Gmail inboxes, Motion API connected, Google Sheets, Drive, etc — pretty deep setup. The product itself? Legitimately excellent. The writing style capture is kind of scary good. Cross-thread context is something I haven't found anywhere else. When it works the way it's supposed to, it saves me real time every single day. But the credits switch in March broke my trust a little. I actually had a conversation with the Jace team back in January and flagged that a Manus-style credits model would be a problem for power users — specifically people running multi-tool-call workflows. Those concerns didn't really land. The switch went through with minimal communication to existing users, my account got stuck in a migration loop for a few days, and credits didn't reset properly after I purchased the annual plan. The structural issue: there's no middle ground between 40k and 80k credits — just double the price. And you get charged for auto-drafts you never use, which adds up fast when you have 126+ rules firing. No transparency on what each action actually costs, so you're basically just watching the number go down. I've sent detailed feedback directly to the team. I'm not bailing (yet) — the product is too good for that. But if you're a power operator considering Jace, go in with eyes open on the credit economics. It's not a dealbreaker, but it's a conversation you'll eventually need to have with them.

It was initially really good but functionality has been declining and bugs aren't getting fixed. The support team can't provide me with estimated timelines to fix bugs, one bug that has been outstanding for months now is that at least 1 email is completely missing from my inbox which is a huge concern. It is a really great product but I wish they would focus on it and fix bugs and keep building it out.
