Passive time tracking for lawyers: the 2026 landscape

Last updated: September 2026  ·  By TimeFlow Legal Inc.

Passive timekeeping stopped being niche around 2024. There are now at least a dozen products promising to capture your billable work without a stopwatch, and they differ more than the marketing suggests.

This guide sorts them by what they actually do. We built one of them, Timeflow, and we have said where it fits and where it does not.

The two tiers

Most confusion in this market comes from treating these as one category. They are two.

1. Activity trackers. Log what you did; you write the entry. The cheapest tier. Examples: Memtime, and to a degree WiseTime.
2. Narrative generators. Log the activity and draft the client-ready description, usually with compliance checks against billing guidelines. Priced accordingly, often custom. Examples: PointOne, Laurel, BigHand SmartTime, Intapp Time.

Work out which tier you need before comparing prices, or you will compare a simple activity log against a full narrative engine and conclude the cheaper one is better value.

The tools at a glance

Descriptions reflect each vendor's public positioning as of September 2026. Pricing models change; confirm current plans and figures with each vendor directly.

The tools, one by one

PointOne

PointOne captures work across your applications and drafts client-ready narratives, with checks against billing guidelines. It is aimed at mid-size and large firms and is sold on custom pricing. Best for: firms whose write-offs come from vague descriptions. Limitation: enterprise sales and pricing make it a heavy lift for a solo.

Laurel

Laurel records activity across desktop and cloud tools and generates time entries automatically, serving both law and accounting firms. It is built for large organizations and priced accordingly. Best for: large firms and professional-services groups with many timekeepers. Limitation: not designed or priced for small practices.

BigHand SmartTime

SmartTime captures time passively and routes entries through approval workflows, and sits inside BigHand's wider suite for large firms. Best for: large firms that need supervisory review before entries post. Limitation: enterprise deployment that assumes an existing practice management or finance system.

Intapp Time

Intapp Time is enterprise time capture for firms already running Intapp or legacy financial systems, with a focus on compliance and integration. Best for: large firms standardizing on Intapp. Limitation: custom pricing and implementation; not a fit for small firms.

Ajax

Ajax generates time entries and narratives from your activity and is positioned for solos and small firms rather than enterprises. Best for: small practices that want written narratives, not just a log. Limitation: confirm which practice management systems it feeds before committing.

Billables.ai

Billables.ai passively captures work for solo and boutique practices and hands back draft entries. Best for: solo and boutique firms that want capture without enterprise overhead. Limitation: it is a capture layer, so check what billing system it sends entries to.

Lawgro MagicTime

MagicTime is the passive capture component of Lawgro's practice management platform. Best for: firms already using, or considering, Lawgro. Limitation: its value is tied to the Lawgro ecosystem.

WiseTime

WiseTime reads application and window titles, builds a private timeline, and auto-tags activity to cases, then pushes entries into your existing billing system. It has a long track record, particularly in IP and patent practice. Best for: IP and patent firms, and any firm that already runs a practice management system it likes. Limitation: it needs a separate system to bill from.

Memtime

Memtime automatically logs which programs and files you used, on a rule-based model, and leaves you to turn that log into entries. It is simple and inexpensive. Best for: solos who want a reliable activity log and are happy to write their own entries. Limitation: not legal-specific; no narrative drafting or matter matching.

Timeflow

Timeflow captures activity at the operating-system level, matches it to matters from client emails, names and keywords, and walks you through a guided end-of-day review. It is a standalone program, so you do not need a practice management system to use it, and it works alongside any practice management system because you can export your time entries. Best for: solo, small and medium firms. Limitation: desktop only, so work away from the computer needs a manual timer or manual entry.

How to actually choose

1. Decide if you need the narrative written. If your billing guidelines are strict or your write-offs come from vague descriptions, you need tier 2. If your descriptions are fine and the problem is missing entries, tier 1 will do.
2. Check whether it needs a system behind it. Several of these are capture layers that assume you already pay for practice management. Add that to the price.
3. Pilot two for two weeks on real matters. Compare recovered billable time and how much editing each draft entry needs. The second number is what determines whether you keep using it in month three.
4. Read the privacy model before the feature list. Ask specifically: window titles or screen contents? Is anything submitted without approval? Where is data stored, and under whose jurisdiction?

The privacy question

Every product here watches you work, which is the point and also the objection. The credible ones read application names and window titles rather than keystrokes or screen contents, and none of them should be billing anything you have not approved.

Ask any vendor these three questions before a trial: what exactly is captured, who can see it inside the firm, and can an entry reach an invoice without a human approving it. If a vendor is vague on the third one, that tells you something.

FAQ

How do lawyers track billable hours automatically?

Passive timekeeping software runs on the lawyer's computer and records which application and document are active, breaking the day into segments and detecting idle time. It matches those segments to matters using client names, email addresses and matter keywords, then presents draft entries for the lawyer to edit and approve.

How much billable time do lawyers actually lose?

Estimates vary widely and most published figures come from vendors. Treat any specific percentage with suspicion. The reliable test is your own: run a passive tracker for two weeks and compare what it captured against what you would have billed.

Does passive time tracking work if I use paper files and phone calls?

Partly. Anything happening off the computer needs a manual timer or a manual entry. If most of your day is court, calls and paper, the gain is smaller than the marketing suggests.
