Before going live, the host loads the question flow, guest background, and must-cover topics into the teleprompter, while the producer prepares backup questions in a separate control panel. Once the show begins, the system transcribes the host and guest separately and maps the conversation back to the outline in real time. When a guest fully covers a question, that item fades out. When a preset topic appears, a guest repeatedly evades an issue, or a new specific name comes up, a one-line cue appears at the edge of the screen. The host can expand it into a follow-up with one click or ignore it and keep their own pace; the system never interrupts by automatically jumping to another question. An off-camera producer can quietly insert a question, and the system places it in a more suitable opening based on what has already been discussed. Afterward, the team receives a review transcript showing question coverage and key moments, making it easier to edit the session or prepare the next one. The first version serves single-guest interviews in one primary language, with every participant confirming consent to recording and transcription before the session. It does not make editorial judgments for the host or generate follow-ups based on unverified facts. ## Why now (backed by facts) As observed on August 31, Sayscroll ranked eighth in Product Hunt’s new-product feed, giving its voice-following teleprompter prominent exposure. As hosts begin to expect teleprompters to understand off-script remarks, repeated questions and missed follow-up leads in live interviews become more visible. ## Direction (model inference, not independently verified) Target user: The core user is a live-interview host supported by an off-camera producer, especially teams running live podcasts, virtual summits, and brand interviews. Once live, guests often answer in an order that departs from the planned outline, while the host must manage the camera, time, and follow-ups. Shuffling through notes interrupts listening, while basic auto-scroll cannot tell whether a topic has already been covered. They need quiet status cues, not a system that takes over the interview. Minimal entry point: Start in the browser by taking separate host and guest audio tracks, rather than relying entirely on post hoc speaker diarization. Real-time transcription can use Deepgram’s WebSocket API, which returns word-level timestamps and speaker labels and can return entities in final results. Break the outline into questions, required topics, and a people-name glossary. Match each guest segment to questions with vector similarity, then use a small model to decide whether it was merely mentioned or fully answered. Low-confidence cases are marked as candidates rather than faded automatically. Producer questions enter a queue through a real-time channel; the first version ranks them only by topic repetition and recency. The review transcript reuses the same timestamp data instead of requiring a separate editing system. The strongest case against: A false judgment that a question has been answered could cause a host to miss something that still needs confirmation, especially when a guest only alludes to it vaguely. Speaker crosstalk, accents, and network jitter can also assign cues to the wrong person. Without enough context, detecting new names or topics can surface useless or even unverified follow-ups. Even slight prompt latency can compete with the host’s natural reaction time. Continuous transcription also raises issues around recording consent, retention of sensitive material, and vendor data handling. Teams may resist changing their existing outline and production workflows, so the product must preserve manual control and provide clear supporting excerpts. These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty. ## Punching above weight (model inference) Recruit initial users from independent podcast producers, live-show teams, and virtual-event hosts. They typically already use browser-based recording studios and can quickly schedule real interviews for testing. Demonstrate the product side by side with a public interview, showing repeated questions fade away and follow-up leads get captured. Offer a per-session trial that lets producers import an existing outline and start immediately. Branded review transcripts can be shared with editors, encouraging adoption within the team. ## Competitors & gaps (model inference) - Tellie: Tellie already follows the words actually spoken and handles pauses, skipped words, and ad-libbing. It also flags content not yet covered, provides a post-session review, and emphasizes local operation and invisibility in screen shares. Those capabilities cover the core experience of knowing whether a script has been delivered, directly validating demand adjacent to semantic teleprompting. Its public materials, however, still center on a single person delivering a script. They do not explain how it distinguishes a host from a guest or show items being cleared when a guest naturally answers a later question. There is also no clear support for producers inserting questions, queueing them around conversational openings, or surfacing follow-ups from new leads. The opening for interview prompting is to turn single-speaker script tracking into two-party conversation-state management, with every prompt traceable to the exact preceding remark. - Riverside: Riverside places a teleprompter directly inside its recording and live-streaming studio. Hosts and producers can both access the script, multiple people can edit it together, and hosts can adjust scroll speed or pop the window out. It already owns the recording, permissions, guest-access, and team-collaboration entry points, reducing the friction of adding another tool. Its public workflow still centers on pasting in a script and controlling auto-scroll; it does not say that it can determine from both speakers' remarks whether a question has been answered. Nor does it show real-time follow-up cues for new people, topics, or signs of evasion. The opportunity is not to rebuild a remote studio, but to join existing live workflows as a side-screen tool. The product must prove that its semantic cues are quiet enough, latency is low enough, and producer-inserted questions do not disrupt the host’s live rhythm. ## How it makes money (model inference) Charge production teams a monthly subscription that includes a set allowance of live-transcription hours, host seats, and producer-control access. Bill overages by transcription time. Put recap-transcript exports, team template libraries, and longer content retention in higher tiers. ## Source context Theme: Sayscroll: AI teleprompter that follows your voice Trigger Product Hunt launch: Sayscroll — The AI Teleprompter that scrolls as you speak This records only that the launch appeared in Product Hunt's public feed and when it was observed.
