Comparison
Blackbox vs Fireflies.ai
Fireflies.ai is a meeting notetaker that joins your calls, records them, and gives the team a searchable archive with CRM integrations. Blackbox is a live assistant that never joins, answers from your own documents, and hides itself from the screen you are sharing. The overlap is smaller than the category labels suggest.
The short answer
Choose Fireflies.ai when the organisation needs coverage: every meeting captured, summarised, pushed into the CRM and searchable later. Choose Blackbox when one person on one call needs the right answer within five seconds and would rather nobody knew where it came from.

Coverage versus the single call
Fireflies is bought by teams. The value compounds when every rep's calls land in one place, when managers can review them, and when the notes reach the CRM without anyone typing. That is a real and well-solved problem, and it is an organisational one.
Blackbox is bought by the person on the call. It does not try to give your VP visibility into the pipeline. It tries to stop you saying “let me get back to you on that” for the third time in one meeting, because the answer was in a PDF you have read twice and cannot recall under pressure.
If both problems are real for you, both tools can run at once. Only one of them is in the meeting.
Live Assist and the shared screen
Fireflies offers in-call suggestions, so this is not a case of one tool helping live and the other not. The distinction is narrower and more practical: what happens when you present.
A demo or a technical review is mostly screen sharing. Anything drawn on top of your screen is in the stream the other side receives. Blackbox excludes its overlay from screen capture at the operating system level on macOS and Windows, so the prompt sits on your display and is absent from theirs. That property is the reason the product exists, and it is not something a notetaker in the attendee list is trying to provide.
Where the answer comes from
Suggested talking points are generated from the conversation. Useful, but general. When a prospect asks whether you support SCIM provisioning, or how your uptime commitment compares with the vendor they already use, a general suggestion is not what you need — the specific sentence from your own documentation is.
Blackbox is built around a private vault you fill: security whitepapers, pricing tiers, SLAs, battlecards, runbooks. Every answer is drawn from them, so what appears on screen is something your company has already committed to in writing.
When Fireflies.ai is the better choice
If you need meetings in your CRM, a shared archive, manager review or coverage across a team, Fireflies does all of that and Blackbox does none of it. If a visible notetaker is normal in your meetings and nobody minds, the invisibility Blackbox is built around is not solving anything for you. And Fireflies has a free tier to try; Blackbox does not.

Get BlackboxFrequently asked questions
- Does Fireflies.ai join the meeting as a bot?
- Yes. Fireflies captures calls by sending a notetaker into them, so it appears in the participant list. Blackbox reads the audio locally on your machine and never joins, so nothing extra shows up for the other attendees.
- Fireflies has Live Assist — how is that different from Blackbox?
- Both surface help during the call. Fireflies suggests talking points from within a tool that is already in the meeting. Blackbox answers from documents you uploaded and renders the answer on an overlay excluded from screen capture, so it stays off a shared screen.
- Which is better value for a team?
- Fireflies, if the job is capturing and distributing every meeting across a team, with CRM integrations and a searchable archive. Blackbox is priced and built for the individual on the call, not for organisation-wide coverage.
- Does Blackbox integrate with my CRM?
- Not today. Blackbox is focused on the live call: your documents go in, answers come out on screen. If pushing notes into Salesforce or HubSpot automatically is a requirement, a dedicated notetaker covers that better.
- Can I run Fireflies and Blackbox on the same call?
- Yes. Only Fireflies joins the meeting, so there is no conflict. A common setup is Fireflies for the team's record and Blackbox for your own live answers.
