About a dozen US states, California among them, require everyone on a call to agree before it is recorded, according to the Digital Media Law Project’s state-by-state guide. That single fact matters more to a solo consultant choosing an AI note-taker than any feature list. These tools record, transcribe and summarize your calls, which means they also decide how visible the recording is to the person on the other end.
Below, we compare four popular options (Fathom, Otter, Fireflies and Granola) through the lens that actually matters for a one-person business: what the client sees, what the free plan really covers, and what you pay once you outgrow it.
The short version, if you only read one section
- Fathom is the easiest place to start for free, with a generous free plan for recording and transcripts.
- Otter is cheap on a paid plan but its free tier is tight, with per-conversation time limits.
- Fireflies is the strongest at searching across many past calls, which suits consultants who reuse insights.
- Granola is the main “no bot” option: it captures audio on your own computer instead of joining the call as a visible participant.
Prices and limits in this category change often. The figures below reflect public pricing and independent comparisons such as TechRepublic’s 2026 roundup and Granola’s own pricing comparison at the time of writing. Check each vendor’s pricing page before you subscribe, and treat any vendor’s comparison of its rivals with healthy suspicion.
Round one: what your client sees
Fathom, Otter and Fireflies typically join a Zoom, Google Meet or Teams call as a named bot. That is transparent, which is good, but it also changes the room. A nervous prospect seeing “Notetaker” appear in the participant list may say less, and some corporate clients block outside bots entirely.
Granola works differently. It runs on your computer and transcribes the audio your machine hears, so no extra participant appears. That feels smoother, and it is also the riskier choice if you skip the consent step. No bot does not mean no recording. In all-party consent states you still need to tell people and get their agreement, and doing so is simply good manners everywhere else.
Verdict: bots win on built-in transparency; Granola wins on a natural conversation, provided you say “I use an AI note-taker, is that okay?” at the start of every call.
Round two: the free plan, honestly
Free plans in this category are designed to get you hooked, then cap you where it hurts.
- Fathom is widely described as having the most generous free plan, with unlimited recordings and transcripts; the smartest AI summaries and integrations sit behind paid tiers.
- Otter limits the length of each free conversation (reported at 30 minutes), which cuts off most real client calls.
- Fireflies has a usable free tier, but limits how far back you can search and how much storage you get.
- Granola offers a free tier, but independent sources disagree on its exact limits (a cap on meeting history versus a fixed number of lifetime meetings), and its app has been Mac-first.
Verdict: if you want to trial the idea for a month without paying, Fathom is the safest bet. Do not judge Otter by its free plan.
Round three: what you pay once it sticks
Paid entry plans cluster between roughly $8 and $15 a month per person on annual billing. Reported figures at the time of writing: Otter Pro around $8.33 a month billed yearly, Fireflies around $10, Granola’s Business plan at $14 and Fathom around $15. Monthly billing usually costs more.
For a solo consultant, the cost difference between these is smaller than one billable hour a year. Do not pick on price. Pick on the workflow you will actually keep using, then pay for that one tool and cancel the rest. If you are stacking AI subscriptions, our breakdown of what one AI step really costs is a useful companion read.
Round four: what happens to the transcript
A call transcript is some of the most sensitive data a consultant holds: client strategy, numbers, sometimes personal details. Before choosing, check three things in each tool’s settings and policy:
- Whether your recordings are used to train the vendor’s AI, and how to opt out.
- How long recordings and transcripts are kept, and whether you can set automatic deletion.
- Who can open shared summaries, especially links you send to clients.
If you paste transcripts into ChatGPT or Claude afterwards, the same questions apply there. Our comparison of ChatGPT locked chats, Temporary Chat and Claude incognito covers which of those settings actually protect client data.
Do you need a dedicated note-taker at all?
Here is the skeptical take. Zoom, Google Meet and Microsoft Teams all now offer some form of built-in AI summary on certain paid plans, and a phone voice memo plus a general AI assistant covers a surprising amount. Our beginner guide to speech to text shows that workflow step by step.
A dedicated tool earns its fee when you have five or more client calls a week and you regularly need to find “what did they say about the budget in September?” Below that volume, a built-in summary or a manual transcript is often enough.
Our pick by situation
- Testing the idea for free: Fathom.
- Lowest paid price, many calls: Otter Pro, after checking its minute allowance fits your month.
- Research-heavy consulting, lots of searching back: Fireflies.
- Sales or sensitive conversations where a bot feels awkward: Granola, with a spoken consent line every time.
Whichever you choose, write your consent sentence once, put it in your calendar invite template, and say it out loud at the top of the call. That habit protects you more than any feature. How many client calls do you take in a typical week, and is that enough to justify a dedicated tool?
