Chatter
Private AI English speaking practice
Complete a four-turn Daily Rehearsal, review carefully checked wording, say it again, and return to saved phrases later. Chatter runs on-device with no Studio AM account, ad, tracker, or cloud AI server.
On the App Store this is listed as Speak English: AI Conversation.


Practice the part that requires speaking
Reading and vocabulary matter, but they do not replace answering someone in real time. Chatter gives an A2–B1 learner a private conversation partner that can wait, respond in character, and let the learner try again without scheduling a tutor or sending speech to a cloud AI service.
Open Daily Rehearsal and complete four spoken turns in one everyday or workplace situation. When bounded local checks accept a wording suggestion that preserves your meaning, Chatter shows the exact changed words and a short reason. Say It Again lets you speak the checked line once more, and Practice Again can return an accepted phrase later from the saved source.
An authored model-free walkthrough inside Chatter demonstrates Say, Check, Say Again, and Return before you subscribe or download a model. It uses no microphone or AI and saves no conversation. Real Daily Rehearsal and conversation work uses your own spoken or typed words with an on-device partner.
What the feedback measures
Chatter is a conversation and phrasing coach, not a pronunciation judge. Its recap can summarize speaking pace, filler words, and answer-length trends from spoken turns. Say It Again compares an on-device transcript with an improved sentence so the learner can practice the wording; it does not score an accent or claim to diagnose pronunciation.
Generated suggestions can be wrong. Chatter uses a deterministic word comparison for the visible changes, but the proposed sentence still comes from a compatible on-device model and should be treated as a useful prompt rather than a grammar textbook. The app does not prove that any two arbitrary sentences have the same meaning.
Private by architecture
Speech recognition, partner replies, checked wording, recaps, and transcript matching run on the iPhone or iPad. Chatter keeps no microphone recording. The transcript, accepted wording, recap, and speaking duration can be saved in the local archive; the app does not sync that archive through CloudKit and has no Studio AM account or ads. Studio AM receives no conversation content, product analytics, or tracking data.
Some devices can use Apple’s built-in on-device model. Other compatible devices may be offered an optional conversation model downloaded directly from Hugging Face based on actual memory and free storage. Pro can also download optional natural-voice files directly from Hugging Face. Neither request contains voice, transcript, conversation, partner reply, or other practice content. The conversation model is stored in Chatter’s app-local container rather than a shared App Group, and natural-voice playback stays on-device after download. Hugging Face may collect CoarseLocation, OtherDiagnosticData, and ProductInteraction with linked=true and tracking=false for AppFunctionality, Analytics, and Other purposes under its own privacy policy. Studio AM does not receive that provider data, product analytics, or tracking. Download size, model availability, memory, and storage needs vary by device. Those downloads and App Store purchase or restore require a connection; practice works offline after the selected model is ready.
Your archive stays yours
An active monthly or annual subscription, or a restored legacy lifetime entitlement, covers Daily Rehearsal, starting and continuing conversations, checked wording, coaching, metrics, Say It Again, Practice Again, and voice output. The monthly and annual plans unlock the same Pro feature level. If access ends, none of that fresh work continues, but saved work is not held hostage. The archive remains available to read, search, export, and delete. Export includes human-readable Markdown plus a lossless, versioned JSON file containing every saved field.
The App Store purchase sheet shows the subscription products actually available to you, their local prices, eligibility, renewal periods, and terms. There is no general free AI-practice tier. A retired lifetime purchase is no longer sold, but Chatter continues to recognize and restore it for verified earlier owners.
Chatter’s interface and conversations are currently in English. It requires iOS 26 or iPadOS 26, and its setup screen checks which compatible on-device model path is available on that particular device.
Common questions
Chatter is a private iPhone and iPad app for A2–B1 English speaking practice. Its distinctive loop is Daily Rehearsal, checked wording, Say It Again, Practice Again, and a private local archive. Daily Rehearsal guides four spoken turns through one situation. Bounded local checks can offer a meaning-preserving wording suggestion; Say It Again compares an on-device transcript with that exact line; Practice Again returns an accepted phrase from its saved source. An authored model-free walkthrough demonstrates the loop without a purchase, model download, microphone, or saved conversation. Real AI practice requires an active monthly or annual subscription or a restored legacy lifetime entitlement. The App Store purchase sheet is authoritative for availability, price, eligibility, and renewal terms. After access ends, saved conversations remain readable, searchable, exportable as Markdown plus lossless versioned JSON, and deletable. Optional compatible conversation-model and natural-voice files download directly from Hugging Face. Neither request sends voice, transcript, conversation, partner reply, or other practice content. Hugging Face may collect CoarseLocation, OtherDiagnosticData, and ProductInteraction with linked=true and tracking=false for AppFunctionality, Analytics, and Other purposes; Studio AM receives none of that provider data or practice content.
Is Chatter free? How much does it cost?
Real AI practice requires an active monthly or annual subscription or a restored legacy lifetime entitlement. The authored walkthrough can demonstrate Say, Check, Say Again, and Return without a purchase or model, but it is not a free AI-practice plan. Apple's purchase sheet shows the products actually available to you, their local prices, eligibility, renewal periods, and terms. A retired lifetime purchase is not sold, but remains restorable for verified earlier owners.
What happens to my conversations if I stop subscribing?
They stay yours. Without active access, the archive still lets you read, search, export, and delete saved conversations. Export creates readable Markdown and a lossless, versioned JSON copy. Starting or continuing a conversation and generating replies, corrections, coaching, metrics, drills, or voice output remain paused until access returns.
Does Chatter score my pronunciation or accent?
No. Chatter focuses on conversation, grammar, and natural phrasing. Say It Again compares the words in an on-device transcript with the improved line; it is not pronunciation or accent scoring.
Does my voice get sent to a server?
No. Chatter requires on-device speech recognition, does not retain microphone audio, and runs conversation and coaching models on the device. If you choose the optional paths, Chatter downloads compatible conversation-model and natural-voice files directly from Hugging Face. The conversation model is stored in its app-local container, and natural-voice playback runs on-device after download. Neither request sends voice, transcript, conversation, partner reply, or other practice content. Hugging Face may collect CoarseLocation, OtherDiagnosticData, and ProductInteraction with linked=true and tracking=false for AppFunctionality, Analytics, and Other purposes under its own policy, but Studio AM does not receive that provider data, product analytics, or tracking. App Store purchase or restore also needs a connection; practice works offline after setup.
What can I practice?
Daily Rehearsal guides four spoken turns through one everyday or workplace situation. When bounded checks accept a meaning-preserving wording suggestion, Say It Again lets you rehearse the exact checked line and Practice Again can return it later from the saved source. You can also use free-form conversation, everyday situations, and workplace roleplays. The doctor situation is language practice, not medical advice. Chatter is designed for A2–B1 learners; its interface and conversations are in English.
What device do I need?
Chatter requires iOS 26 or iPadOS 26. It can use Apple's on-device model when that runtime is available; another supported device with sufficient memory may be offered a compatible local-model download. A downloaded model is stored in Chatter's app-local container, not a shared App Group. The app checks the exact model path on the device instead of relying on a rough iPhone-generation list.
