How CaseClock compares to passive AI timekeepers
Ajax, Billables AI, and Laurel draft time entries from activity they observe in the background. CaseClock builds each entry from what the lawyer says, out loud, right after the work. Both models aim at the same problem. They ask very different things of you. Here is an honest comparison.
The landscape
Two ways to stop losing billable time
Every tool on this page exists because reconstructing time at the end of the day loses billable work and degrades entry quality. On that diagnosis, we and the passive timekeepers agree completely.
Passive timekeepers answer it by watching. They run in the background, capture activity across email, documents, browsers, calendars, and calls, and use AI to assemble that activity into draft time entries for the lawyer to review later. The lawyer's main job becomes reviewing and releasing what the machine drafted.
CaseClock answers it by asking. The lawyer speaks a short description of the work right after finishing it, and CaseClock turns that description into a structured, matter-linked draft time entry for review and approval. Nothing is captured unless the lawyer chooses to say it.
Neither model is dishonest, and each has real strengths. The comparisons below lay out how each product works according to its own public materials, where it is genuinely strong, and why we built CaseClock the other way.

Four questions worth asking about any capture model
Where does the entry start?
A passive tool starts from observed activity: which document was open, which call happened, how long a window had focus. A tool like CaseClock starts from the lawyer's own account of the work. The starting point shapes everything the entry becomes. We wrote up the difference in detail in our piece on voice capture versus reconstruction.
Voice capture vs end-of-day reconstructionWhen does billing judgment happen?
Activity is not billing. Someone still decides what was billable, for which client, and how it should be described. With passive capture, that judgment happens at review time, hours after the work. With contemporaneous voice capture, it happens while the work is still in the lawyer's head.
Why voice capture works for legal billingWhat does the tool have to observe?
A background agent can only draft entries from what it can see, so its capture surface spans the applications where privileged and confidential work happens. The vendors on this page describe real safeguards, including encryption, purging of raw activity data, and access controls. A dictated entry raises a narrower question, because the only content that exists is what the lawyer chose to say.
CaseClock vs passive AI timekeepers, the model comparisonHow can you try it?
Pricing transparency varies. Billables AI publishes subscription pricing on its site, with plans starting from $59 per user per month on monthly billing. Ajax and Laurel did not publish pricing on their sites as of September 1, 2026, and Ajax describes per-seat annual contracts quoted through a sales call, with a free pilot to start. CaseClock offers a 45-day free trial with no credit card required, you can start on your own, and current CaseClock pricing is always on our pricing page.

Where Clio fits
Clio isn't part of this comparison. CaseClock works with Clio, and for firms on Clio the two are complementary: CaseClock is where the lawyer captures and approves time entries, and Clio Billing is where approved entries become bills, invoices, and payments.
Approved CaseClock entries can be sent directly into Clio where the integration and workflow apply, so the billing side of your practice keeps running exactly where it runs today.
Try the lawyer-controlled model on your own work
Capture a few real entries by voice this week and compare them to what you would have reconstructed at 6pm. That test costs nothing and settles the question better than any comparison page.
