Which AI Notetakers Can Bankers Use on Deal Calls?

Investment bankers can use only the AI notetakers their firm's compliance team has approved for deal calls. In practice that means a tool whose transcripts and summaries reach the firm's archive under SEC Rule 17a-4 and FINRA Rule 4511, that respects information barriers and that your NDAs allow. Anything else is an off-channel risk.

This guide is vendor-neutral. It covers the four constraints that decide the answer at a bank (MNPI, recordkeeping, client confidentiality and firm approval), the questions to put to any vendor, the calls where a notetaker is a bad idea, and the main tool types. Reline makes an AI notetaker, so the last section says plainly where it stands, including what it lacks for deal work today.

Deal calls are full of material nonpublic information. Section 15(g) of the Securities Exchange Act requires registered broker-dealers to have written policies and procedures, suited to their business, that prevent the misuse of MNPI. The SEC staff calls these controls information barriers.

An AI notetaker makes new copies of that information: a recording, a transcript, a summary, maybe a chat history and a message in Slack. Each copy needs to sit on the right side of the wall. Ask who can open it by default, whether search or an AI assistant can reach notes from another deal team, and whether a summary can be posted to a channel outside the wall.

FINRA's books and records guidance summarizes the core rules. Under Exchange Act Rule 17a-4(b)(4), broker-dealers keep communications relating to their business as such for at least three years, the first two in an easily accessible place. That covers internal and external electronic communications on any platform, and a firm may not allow a type of electronic communication it cannot record and keep. FINRA Rule 4511 sets a six-year default where no other period applies and requires the format and media that Rule 17a-4 allows: an electronic system with a time-stamped audit trail, or write-once (WORM) storage. Outsourcing recordkeeping to a vendor does not move the responsibility.

Is an AI transcript or summary a business communication? FINRA has not settled that. Regulatory Notice 25-07 (April 2025), a request for comment on modernizing FINRA rules, asks firms what recordkeeping challenges AI-generated communications raise and gives AI-generated transcripts or summaries of meetings as an example. It does not propose a rule. Regulatory Notice 24-09 (June 2024) says FINRA rules are technology neutral and apply to generative AI, including features embedded in third-party products. The 2026 FINRA oversight report suggests storing prompt and output logs. Until your compliance team decides otherwise, treat AI notes from deal calls as records.

On September 27, 2022, the SEC charged 16 firms, which agreed to pay more than $1.1 billion in combined penalties for failing to keep electronic communications. On August 14, 2024, 26 more firms agreed to pay $392.75 million. The rules behind those cases, Rule 17a-4 and FINRA Rule 4511, still apply. A notetaker your firm cannot capture is the same gap as a business text on WhatsApp.

Engagement letters and NDAs with counterparties limit who may receive confidential information, and some limit how it may be stored or shared with third parties. A notetaker vendor and its AI providers are third parties. The SEC staff report notes that, under Rule 10b5-2, a duty of trust or confidence exists whenever a person agrees to keep information confidential. Read the NDA's definition of representatives and ask counsel whether a software processor fits it.

Banks restrict which software employees can install and which meeting tools they can use. Installing an unapproved notetaker breaks policy, however good the tool is. The usual path: a request through IT, a compliance review of recordkeeping, surveillance and information barriers, and a legal review of the DPA and subprocessors.

• Compliance has not approved the tool for client or deal communications.
• The notes would land outside the wall: a shared workspace, a personal account, a chat channel.
• Someone is being brought over the wall and compliance has not yet logged it.
• The NDA or the counterparty restricts recording or third-party processing, or someone on the call objects.
• Counsel is present for privileged advice. Recording can create discoverable copies.
• You are on a personal device or a personal account.
• The AI summary would be the only record of what was agreed. Summaries can drop or misstate a point, so a person should check them against the transcript.

1. Use only the firm-approved tool, signed in with your firm account.
2. Tell everyone at the start of the call, and follow consent law in each participant's location.
3. Keep one space per deal, with access limited to the deal team list that compliance maintains.
4. Review and correct the AI notes the same day. The transcript is the source; the summary is a draft.
5. Confirm the record reached the archive. Do not keep side copies in downloads, personal apps or forwarded emails.
6. Do not post deal notes to chat channels outside the wall.
7. At signing, close or termination, follow the retention schedule, not personal habit.

Reline is bot-free: it captures microphone and system audio locally on Mac, Windows, Linux (beta) or in the browser, then transcribes, summarizes and stores it in the cloud. Data is hosted in the United States, with the database on Convex and recordings on Cloudflare R2.

The plain verdict: if you work at a broker-dealer and the call is a client or deal communication, Reline is not the right tool today. It does not feed your firm's archive, it has no retention or legal-hold controls, and it has no SOC 2 report. Teams outside broker-dealer recordkeeping, such as some corporate development teams, still carry MNPI and NDA duties and should run the vendor questions above with their own counsel.
