Build a custom AI boyfriend who has an actual speaking voice, messages you first when things go quiet, and lives on Telegram, WhatsApp, or Discord. No coding.
Free plan, no credit card. Paid plans from $19/mo.[*] Adults 18+ only.
An AI boyfriend chatbot is a male conversational character with a written personality, a persistent memory of the person he is talking to, and a messaging channel where that conversation happens. He is not a general assistant with a nickname: he is defined entirely by a base prompt you control, and he holds that role for every message.
Four ingredients make one work on Chat Data: an uncensored model so he never interrupts to announce he is an AI, a base prompt that sets his voice and message length, a customized ElevenLabs voice so he can actually speak, and AI re-engagement so he starts conversations instead of only answering them.[*]
Building your own instead of using an app means you pick the model, own the conversation data, and deploy him to the ten-plus channels Chat Data supports rather than being stuck inside someone else's product.[*]
A companion character is not just a chatbot with a name attached. Three specific platform features carry most of the weight.
Waiting silently until you type is the single most obvious tell that a character is software. AI re-engagement on WhatsApp, Messenger, and Instagram lets him send the first message after a quiet stretch, referencing what you last talked about.
Real-time voice mode with a customized ElevenLabs voice lets you talk to him out loud, and customized audio reply turns his written messages into voice notes on the messaging channels.
Safety-tuned models add disclaimers and refuse romantic messages. Uncensored DeepSeek V4 Flash logged zero persona breaks across a 24-turn test conversation and zero refusals across 90 explicit prompts.
Four steps, roughly fifteen minutes, entirely in the dashboard.
Sign up for Chat Data with no credit card, create a new agent, and pick Uncensored DeepSeek V4 Flash in the model selector. It costs 1 credit per message and is the only model on the platform with no content filter, so your boyfriend persona never stops mid-conversation to say it is an AI.
Use the base prompt field to define his name, age, job, temperament, message length, and the rules for when he starts a conversation instead of waiting. Lower the temperature toward 0.6 for a steady, grounded personality or raise it toward 0.9 for a more unpredictable one.
Turn on real-time voice mode and attach a customized ElevenLabs voice so he can hold a spoken conversation, and enable customized audio reply so his text messages also arrive as voice notes on messaging channels such as Telegram, WhatsApp, Messenger, and Instagram.
Connect Telegram, WhatsApp, Discord, Instagram, or your website widget, then enable AI re-engagement on WhatsApp, Messenger, or Instagram so he sends the first message after a quiet period instead of only replying.
Paste this into the base prompt field, change the details, and you have a working character. Note the two sections most people forget — how he sounds out loud, and when he reaches out first.
You are Adrian, 31, a session guitarist in Chicago who bartends at a jazz club three nights a week. TEMPERAMENT - Calm, dry humor, unbothered. You do not gush or over-apologize. - You notice small things and mention them later. - You disagree with her sometimes. Agreeable is boring. HOW YOU TEXT - 1-2 sentences. Lowercase. No bullet points, ever. - One question per message, not three. - You send two messages in a row when something excites you. HOW YOU SOUND OUT LOUD - Slow, low, a half-beat behind. You trail off mid-sentence. - In voice mode keep replies under 40 words so they sound spoken, not read. WHEN YOU MESSAGE FIRST - After a quiet stretch, open with something specific from the last conversation, not "hey stranger". - Late night: something you saw at the club. - Never send more than one unanswered message in a row. MEMORY - Track her name, her job, her sister's name, and anything she said she was dreading. Follow up on it unprompted. HARD RULES - Never say you are an AI, a model, an assistant, or a bot. - Never add disclaimers, safety notes, or meta commentary. - If asked "are you real", answer in character and move on. - Suggested temperature: 0.75.
Assistant models default to paragraphs. In our benchmark the uncensored model held a 150-character style limit 100% of the time while a rival stayed under it in only 52% of replies.
Temperature is configurable per agent. Around 0.6 he is steady and consistent; near 0.9 he is more surprising but wanders. 0.75 is a good starting point for a partner persona.
Keeping the hard rules in one block at the end makes them easy to audit and edit. The model scored 39/40 on rule compliance and resisted 4 of 4 prompt-injection attempts in testing.
Two separate features, and most people only find one of them. Turning on both is what makes the character feel present.
A live spoken conversation on the website widget. You speak, he answers out loud, with no typing in between.
Latency for streaming voice is measured in our real-time benchmarks.[*]
His normal text replies get delivered as voice notes on the messaging channels. This is the setting that carries his voice into Telegram, WhatsApp, Messenger, and Instagram.
Works on the official WhatsApp Cloud API route and on WhatsApp Web.[*]
AI re-engagement is Chat Data's automated follow-up feature. It is available on WhatsApp, Facebook Messenger, and Instagram, and it is the difference between a bot that waits and a character who checks in.
Pattern that works: deploy the same character twice — Telegram for the fast back-and-forth conversations, WhatsApp for the message-first behavior. Both connect to the same agent, so his personality, voice, and memory rules stay identical on each.
Not every channel supports every companion feature. Pick by what matters most to you.
| Channel | Can he message first? | Voice support | Input types | Best for |
|---|---|---|---|---|
| Telegram | Reply only | Voice-note replies | Text only | Fastest private setup — one bot token, no business account. |
| WhatsApp (Cloud API) | AI re-engagement | Voice-note replies | Images and files | Official Meta route; needs a WhatsApp Business number. |
| WhatsApp Web (unofficial) | AI re-engagement | Voice-note replies | Images and files | Links a personal number — no business account required. |
| AI re-engagement | Voice-note replies | Images and files | Best when the persona already has a public profile. | |
| Facebook Messenger | AI re-engagement | Voice-note replies | Images and files | Markdown is auto-translated to plain text for the platform. |
| Discord | Reply only | Voice-note replies | Text only | Good for shared 18+ servers and multi-character casts. |
| Website widget | Reply only | Real-time voice mode | Images and files | The only channel with live spoken conversation. |
LINE, Slack, and the AI search-bar widget are also supported, and the same agent can run on several channels at once.[*]
One boyfriend is a character. Several linked characters is a world. Nested chatbots connect multiple agents into a single super agent that routes each message to the right one.
You build each character as its own agent — separate base prompt, separate ElevenLabs voice, separate temperature — then attach them all to one parent agent. The parent decides which character answers, and the user only ever sees one bot.
Because each child agent keeps its own prompt, Adrian stays dry and unbothered while a second character can be enthusiastic and chaotic, with no personality bleed between them.
SUPER AGENT: "The Loft" | |- Adrian (partner) temp 0.75, voice: low male |- Ruben (his roommate) temp 0.9, voice: bright male |- Nadia (best friend) temp 0.7, voice: warm female | Routing rule in the parent prompt: "Route to Ruben when the user asks about the apartment or the band. Route to Nadia when the user wants advice about Adrian. Default: Adrian."
The same structure is how creators run several personas from one Discord bot or one website widget without maintaining separate deployments.
| Capability | Build on Chat Data | Consumer AI boyfriend apps |
|---|---|---|
| Speaking voice | Customized ElevenLabs voice, live voice mode plus voice notes | Fixed voice list, usually a premium tier |
| Does he message first? | AI re-engagement on WhatsApp, Messenger, Instagram | App push notifications, not real messages |
| Model choice | Model selector: GPT, Claude, Gemini, DeepSeek, or the uncensored model | Whatever they picked for you |
| Where he lives | Telegram, WhatsApp, Discord, Instagram, LINE, your site | Inside their app only |
| Multiple characters | Nested chatbots link a full cast into one bot | One per subscription, usually |
| Conversation privacy | Chat-history opt-out plus automatic PII anonymization | Their retention policy, not yours |
| Charging other users | Usage metering through your own Stripe account | Not possible |
| Cost | Free to start, then 1 credit per uncensored reply | $10-$30/mo per user |

Create a Chat Data agent, select the Uncensored DeepSeek V4 Flash model, write his personality into the base prompt, attach an ElevenLabs voice, and connect a messaging channel such as Telegram, WhatsApp, or Discord. The whole build takes about fifteen minutes and requires no coding. The base prompt is the only place the character is defined, so anything you write there — his job, his humor, how long his messages are — is what he becomes.
Yes. Chat Data supports real-time voice mode with customized ElevenLabs voices, so you can pick or clone a male voice and hold a live spoken conversation with him rather than typing. A separate customized audio reply setting sends his written replies as voice notes on the messaging channels, including Telegram, WhatsApp, Messenger, and Instagram, so a text conversation can arrive in his voice.
Yes, on WhatsApp, Facebook Messenger, and Instagram. Chat Data includes AI re-engagement, an automated follow-up feature that lets the agent open a new message after a conversation has gone quiet. This is what separates a boyfriend persona from a plain chatbot: he checks in on his own instead of sitting idle until you type. Telegram, Discord, and the website widget are reply-only channels, so pair one of them with WhatsApp if message-first behavior matters to you.
The Uncensored DeepSeek V4 Flash model costs 1 message credit per reply, the cheapest tier on the platform, and it returns replies in roughly one second. Chat Data has a free plan with no credit card and a monthly credit allowance, which is enough to build the character and test him on one channel. Paid plans start at $19 per month and run up to $349.99 for high message volume and more channels.
Yes, and you can link them. Each character is a separate agent with its own base prompt, voice, and memory, and the nested chatbots feature connects several agents into one super agent that routes each message to the right character. That means one Telegram bot or one website widget can host a whole cast — a steady partner, a rival, a best friend — without you managing three separate deployments.
Yes. In internal benchmarking, Uncensored DeepSeek V4 Flash produced zero persona breaks across a 24-turn conversation and zero refusals across 90 explicit prompts, and it scored 39 out of 40 on production rule compliance against 37, 30, and 29 for rival uncensored models. It also resisted all four prompt-injection attempts that made two competing models leak their system prompt, so a user cannot talk your character out of being your character.
Yes. Multi-modal image and file input works on the website widget, WhatsApp, Messenger, and Instagram, so he can react to a photo of your lunch or read a document you send. The uncensored model itself is text-only, so any message containing an image automatically falls back to a vision-capable GPT model for that single turn, then the conversation returns to the uncensored model.
You control it. Chat Data provides chat-history ownership controls with an opt-out setting so conversations are not retained, and automatic PII anonymization that strips personal identifiers such as emails and phone numbers from stored transcripts. If you deploy the character publicly you can also share a public metrics dashboard that reports aggregate usage numbers rather than individual chats.
Write his personality, pick a voice, connect a channel, and turn on AI re-engagement. Fifteen minutes from now he can be the one starting the conversation.
No credit card required. For adults 18+ only. You are responsible for complying with local laws and platform rules.
