Turn the product idea below into a locally runnable MVP. ## Idea Solo Scene Partner A phone-based scene partner that reads the other roles, follows improvised changes, and keeps a solo rehearsal moving. ## Product concept When actors rehearse audition sides alone, or short-form video creators record a multi-character dialogue by themselves, what they lack most is a partner who can respond to an improvised line. They paste a script into their phone, mark the character they play and the passage they want to rehearse, then choose voices and speaking rates for the other characters. Once rehearsal starts, the phone reads the scene partners' lines and waits silently for the user’s turn, with no need to free up a hand to tap the next line. If the user says a word incorrectly, skips half a line, or changes the wording on the fly, the system uses what was said and the surrounding scene to find the closest point in the script, then naturally delivers the next line. If the user pauses too long, it can offer just the first few words as a cue or continue according to the rehearsal setting. After each run, the timeline marks only clear stumbles, interruptions, and breaks in emotional continuity. With one tap, users can replay those few seconds with the scene partner’s voice. Creators can save a smooth rehearsal as an audio recording, blocking notes, and a line-by-line pacing sheet, then resume next time from a selected character. The initial version serves solo rehearsal with existing written scripts, first making Chinese and English dialogue handoffs work well. It does not generate new lines or evaluate a performance for the director. It preserves the rhythm of playing a scene with another person while practicing alone. ## Why now (backed by facts) As of September 8, Scriptly ranked 10th in Product Hunt’s new-product feed, suggesting that voice-following teleprompters are drawing creators' attention. That may make actors and creators filming multi-character dialogue alone more likely to expect a phone to keep the scene going after an improvised change. ## Direction (model inference, not independently verified) Target user: The core user is an actor preparing audition sides alone, as well as a short-form video creator recording a multi-character dialogue solo. They need it when they know the text but cannot find a partner to run the scene repeatedly. What they need to practice is not memorizing isolated lines, but picking up cues, pausing, and shifting emotion. The rehearsal should continue after a spontaneous wording change so they can stay in performance mode. Minimal entry point: Start by parsing pasted text into characters, lines, and passages, while allowing manual corrections. Apple’s iOS Speech framework can continuously receive live transcriptions and alternative results. Keep a sliding search window only around the current line. First use word-order edit distance to find candidates, then use sentence similarity to handle rephrasing. At low confidence, pause or offer the opening words as a cue; never jump across scenes on its own. Use AVSpeechSynthesizer to assign a voice and speaking rate to each scene partner. The first version should save only recordings, pause durations, and interruption points, without scoring performances. The strongest case against: If speech recognition mishears an accent, breathy delivery, or a character name, it may jump to the wrong place in the scene. A wrong partner line forces the user to stop and check the phone, directly breaking the rehearsal rhythm. Overly broad semantic matching may also mistake a similar line for one later in the script. When the phone speaker plays the scene partner’s lines, the microphone will pick up the synthesized voice as well, and echo handling adds engineering cost. Mixed Chinese-English dialogue, multiple characters with the same name, and repeated phrasing all need separate testing. Scripts often contain copyrighted material, so cloud transcription raises privacy and retention-period concerns. If it cannot reliably handle omissions and rephrasing, the product becomes little more than an existing cue-word player. 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) Reach the first users through self-tape, theater-club, and acting-class communities. Demo material should directly compare recovery from three mistakes: missing words, rephrasing, and skipping a line. Offer several copyright-free sample scenes so users can experience the pacing immediately. Position the App Store page around "scene partner" and "self-tape reader" for Chinese- and English-language search. ## Competitors & gaps (model inference) - ColdRead: ColdRead already covers the core solo-rehearsal workflow for actors. Users can record or import scene partners' lines and label each line as theirs or their partner’s. During rehearsal, it can play the next line when it hears the user’s ending cue word, continue after a detected pause, and provides a teleprompter and self-tape video recording. This already removes the need to tap for each next line. Its public help materials still organize the workflow around cue words, pause timing, and line-by-line recording. For homophones or cue words that are difficult to recognize, it recommends using the preceding word or a pause-based mode. The opening is to relocate the user in the scene based on the meaning of a full utterance. When users miss words, rephrase, or skip half a line, the system should still identify where they landed. Another opportunity is to automatically flag interruptions, long pauses, and awkward transitions, reducing the need to review recordings segment by segment. ## How it makes money (model inference) Offer a free trial and an individual subscription. The free tier limits the number of scripts and the length of each rehearsal; the subscription unlocks unlimited scripts, multiple character voices, rehearsal recordings, and playback of flagged stumbling points. ## Source context Theme: Scriptly Trigger Product Hunt launch: Scriptly — An iOS teleprompter app controlled by your voice This records only that the launch appeared in Product Hunt's public feed and when it was observed. The feed provides no vote count; do not describe feed order as popularity or market demand. ## Sources - Scriptly: An iOS teleprompter app controlled by your voice (https://www.producthunt.com/products/sciptly) - Speech (https://developer.apple.com/documentation/speech/) - AVSpeechSynthesizer (https://developer.apple.com/documentation/avfaudio/avspeechsynthesizer) - coldRead - The App for Actors - Help (https://coldreadapp.com/help.html) ## Deliverables - Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery. - Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary. - Do not show unverified market numbers in the UI or API. - Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge. - If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code. - If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype. - When done, explain what changed, how to run it, and how to verify it. - Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
