A solo lawyer or small firm on a Mac has four realistic kinds of dictation tool: Apple's built-in Dictation, Dragon (now a Windows product), a Mac app that recognises speech locally, and a cloud dictation service that offers signed data-handling terms. None is approved for client work by default. The choice turns on three questions the ABA's rules raise: do you understand what the tool does, where does client information go, and can you supervise how your staff use it. This guide is not legal advice; your jurisdiction's rules and your firm's policy decide.
Publisher note: SuprFlow publishes this guide and is one of the products discussed. Competitor details come from each company's own pages, checked on 1 October 2026. Prices and features change; confirm before you buy.
What do the ABA rules ask of a lawyer choosing dictation?
The ABA Model Rules are a model; your own state's rules govern you, so check them. Three are central:
- Rule 1.1, Competence. "A lawyer shall provide competent representation to a client" (ABA).
- Rule 1.6(c), Confidentiality. "A lawyer shall make reasonable efforts to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation of a client" (ABA).
- Rule 5.3, Nonlawyer assistance. Partners must make reasonable efforts to ensure the firm has measures giving "reasonable assurance" that nonlawyers' conduct is compatible with the lawyer's obligations (ABA).
ABA Formal Opinion 512 (29 July 2024) applies these rules to generative AI. Plain speech recognition may not be generative AI, but many dictation apps add a language model that rewrites your words, and the opinion notes its concerns "are similar to the issues that exist with other AI tools". In short:
- Understand the tool. Lawyers "need not become GAI experts" but "must have a reasonable understanding of the capabilities and limitations" of the specific tool, or draw on someone who does. Relying on output without "an appropriate degree of independent verification or review" could breach Rule 1.1.
- Assess disclosure before you input. Before entering client information, lawyers "must evaluate the risks that the information will be disclosed to or accessed by others outside the firm", and inside it. For self-learning tools, the opinion says "a client's informed consent is required" before inputting client information.
- Read the terms. "As a baseline, all lawyers should read and understand the Terms of Use, privacy policy, and related contractual terms and policies" of the tools they use, or consult someone who has.
- Set policy and train. Managerial lawyers "must establish clear policies regarding the law firm's permissible use of GAI", and supervisors must ensure staff are trained. For outside vendors, it points to due diligence such as reviewing security policies and confidentiality agreements.
What are the practical options on a Mac?
As each vendor documents it, checked on 1 October 2026. We have not benchmarked any of them.
| Option | Where speech is processed | What the vendor documents | Watch for |
|---|---|---|---|
| Apple Dictation | Keyboard settings tell you whether general text dictation is processed on your device (Apple) | Free and built in. When you turn it on, you choose whether to share audio recordings with Apple ("Not Now" declines) | Apple's Dictation guide describes no custom word list for client names or legal terms |
| Dragon for Mac | Not applicable | Nuance says Dragon Professional Individual for Mac was "discontinued effective 10/22/2018" and it "will no longer provide updates" (Nuance) | Dragon Legal v16 is a Windows product, "optimized for Windows 11", with a legal vocabulary, custom commands and audio-file transcription (Nuance) |
| A local-model Mac app | On the Mac | Speech recognition on the device; for example, BetterDictation and VoiceInk both document local transcription, and SuprFlow (below) | Any optional AI cleanup: BetterDictation Pro sends text to OpenAI; VoiceInk's Cloud Enhancement sends text. We found no audit reports on the pages we read |
| A cloud service with signed terms | On the vendor's servers | Wispr Flow says it "processes dictated audio in the cloud" in the United States, offers SOC 2 Type II and ISO 27001 reports through its Trust Center, and handles data processing addendum requests (Wispr) | Its "Improve the model for everyone" setting "is on by default for Free and Pro"; turn it off, or use a plan where it is off |
| A hybrid app with your own provider | Local or cloud, per mode | Superwhisper says its cloud providers are accessed through "API agreements that include zero-data-retention terms", and lets firms bring their own API keys or sign a DPA (Superwhisper) | Each mode has two settings, speech and language model; check both |
A Business Associate Agreement (Wispr offers one; its security FAQ says "HIPAA-ready dictation requires a signed Business Associate Agreement") is a US health-privacy contract, not a legal-ethics approval. For a law firm it shows the vendor will sign data-handling terms; read what it covers. And "local" covers one step: an app can recognise speech on the Mac and still send text to an AI provider for cleanup. What is AI dictation? explains the two steps.
Which option fits which practice?
- Short emails and notes, little client detail: start with Apple Dictation, decline audio sharing, and check the on-device note in Keyboard settings.
- You relied on Dragon's legal vocabulary and commands: keep a supported Windows setup for that work, or read Dragon for Mac alternatives.
- You want client audio to stay on your Mac: a local-model app, with any AI cleanup either off or local. Expect to do the vendor review yourself if the vendor publishes no audit reports.
- Your firm requires audit reports and signed terms: a cloud service with a Trust Center and a DPA, configured so training and storage are off. You are trading local processing for documented controls.
Where does SuprFlow fit?
SuprFlow is a local-model Mac app for Apple Silicon Macs with macOS 14 or later. Speech recognition runs on the Mac with a downloaded model; Default formatting is local cleanup of punctuation, capitalization and numbers; an optional Cloud API mode sends transcript text, not audio, to a provider you configure. It keeps a local history of recent transcriptions and uses the network for licence checks, updates and usage telemetry. It is not certified for anything: no BAA, no SOC 2 report we can cite, no admin console, no legal vocabulary. The $125 licence is personal; a firm needs separate terms, so contact SuprFlow. Offline dictation for lawyers covers configuring a local workflow.
A pre-pilot checklist
Before any real client information, with a fictional matter:
- Write down the data path for your exact setting: where speech is recognised, and whether and where an AI step runs.
- Read the vendor's terms and privacy policy, noting retention, training and named subprocessors.
- Turn off what you do not need: audio sharing, model improvement, cloud storage, AI rewriting.
- Check local copies: app history, clipboard managers and backups.
- Test meaning, not spelling. Dictate: "Ms. Okafor did not sign the amended lease. We have not agreed to waive clause nine." Confirm both negations survive.
- Decide who reviews dictated text before it is sent or filed.
- Decide whether client consent is needed, especially for any tool that may learn from inputs.
- Record the decision in a short firm policy and train staff on it, as Rule 5.3 contemplates.
Send vendors the law-firm vendor questions.
Questions people ask
What is the best dictation software for lawyers on a Mac?
There is no single answer. Apple Dictation is free; a local-model app keeps audio on the Mac; a cloud service may offer audit reports and signed terms. Match the option to your firm's confidentiality policy.
Does ABA Formal Opinion 512 apply to dictation?
It addresses generative AI tools, and notes that many of its concerns apply to other AI tools too. If your dictation app rewrites text with a language model, treat the opinion as directly relevant. Your state's rules and opinions also apply.
Is local dictation automatically confidential?
No. Speech stays on the Mac, but AI cleanup, local history, backups and the destination app can hold or send copies. Rule 1.6(c) covers the whole path.
