Pre-filled fake group chat about a substitute teacher. iMessage template for school skits.
Substitute teacher chats are a niche but reliable school-content format — the bit is the betrayal when the sub is actually competent and follows the lesson plan.
This template uses a group-chat format with realistic chaotic energy. The recipient's "WAIT NO HOMEWORK??" is the universal student reaction, immediately undercut by the sub apparently caring about the curriculum.
Strong for back-to-school season, "things subs do" compilation videos, or as a reaction setup for any teacher-focused creator. The lowercase + caps mix sells the high school energy.
Use this template
Open the iMessage editor — you can swap the names, times and messages, then download a clean PNG with no watermark. For parody and content only.
Open in iMessage editor →Step by step. Total time: about 60 seconds.
Click 'Open in iMessage editor' below. The conversation is pre-filled — the editor loads with every message, contact name, time and battery percentage already set up exactly like the preview.
Change the contact name (use 'Mom', 'Ex 💀', or any first name with emoji), upload a different avatar, or import a real Instagram profile to auto-fill the photo. The conversation text stays the same — just the people change.
Click any message bubble to edit it. Add new messages, delete ones that don't fit, or use the AI 'Generate reply' button on any single bubble to get an in-character response.

Showing a parody of common phishing/scam patterns (fake bank, fake delivery, fake government agency) alongside the real red flags is high-value education. Every viewer who learns to spot the format saves real money.
Absurd takes on real service notifications — '$48 charge at Burger King in Antarctica', 'order of 47 rubber ducks shipped'. The format works because real service notifications are a universal experience.
Designers building 'what our app's transactional notification would look like' demos. The screenshot format is a clean visual prop for pitch decks and landing-page mockups.

Yes. PostMock renders the authentic iOS bubble shapes (correct corner radius, tail placement on the last message of each group), Apple's exact iMessage blue (#0b93f6) and grey (#e9e9eb), the real iPhone status bar, and proper read receipts. The exported PNG is indistinguishable from a genuine iPhone screen capture.
No. Making a fake screenshot doesn't notify anyone because no real iMessage is ever sent. The conversation only exists in your browser. iMessage itself doesn't have screenshot notifications anyway.
For parody, comedy, fiction, education, and skits — yes, in essentially every country. Don't use it to defame a real person, defraud someone, or fabricate fake evidence. Full legal framework: /blog/is-making-fake-instagram-dm-illegal.

Open the iMessage generator →PostMock is a free browser-based generator for fake chat and phone screenshots. It renders a realistic mockup of a messaging app — WhatsApp, iMessage, Instagram DM, Snapchat, Discord, Telegram, Messenger, Tinder, Bumble, Hinge, ChatGPT, Claude — from text you type, and exports it as a high-resolution PNG. It is used for memes, parody, comedy content, social media posts, UI mockups, presentations and app-design previews.
Yes, and there is never a watermark on any export. Without an account you get 5 free PNG downloads, plus 3 more for each of up to 2 shares (11 in total). After that a free Google sign-in is required, and signed-in users have unlimited downloads. Video exports require sign-in from the first download. There is no paid tier and no subscription.
No install. PostMock runs entirely in the browser on desktop and mobile — there is no app to download and nothing to configure. Editing and preview happen client-side; the screenshot is rendered in your own browser rather than on a server. You can start typing and see the preview without an account.
Describe a scenario in plain language ("two friends arguing about pizza") and PostMock writes the whole conversation for you, in short, natural, realistic messages. It can also continue an existing conversation by writing the other person's next replies. Tweets can be generated the same way.
18 generators in total: 12 chat apps (iMessage, WhatsApp, Instagram DM, Snapchat, Messenger, Telegram, Discord, Tinder, Bumble, Hinge, ChatGPT and Claude), plus tweet/X posts, iPhone call and FaceTime screens, Instagram Stories, WhatsApp Status, and iPhone lock screens with notifications. It also has 80 ready-made scenario templates and 27 how-to guides. A separate tool downloads public Instagram reels and videos.
PostMock is built for parody, comedy, memes, content creation, mockups and design previews, and it says so on every page. Using a fabricated screenshot to deceive, defraud, impersonate a real person, harass someone, or manufacture evidence is wrong and in many places illegal — that is not what the tool is for and it is explicitly discouraged in the product. Creators should label parody content as parody.
Pre-filled fake group chat about a substitute teacher. iMessage template for school skits. It is a ready-made iMessage scenario in the Service & delivery parodies category on PostMock: the conversation is already written, so you open it, adjust the names and details, and export a PNG.
No. A template is a starting point — every message, name, avatar, timestamp and battery level stays editable once it opens in the editor, and you can add or delete messages freely.
