Apps built, not bought.

Web apps, Mac apps, Android apps and AI tools I build with Claude Code, most of them in under a week, including the world's first Bangla screenwriting app and the first Bangla speech-to-text app for Mac. Each one solves a real problem in my business or a client's. Watch them work below; new ones get added as I ship them.

File 01 · AI image and cinema studio

The Alchemist

What it's forBrands and creators who want campaign images, video and ad designs set up the way a photographer or cinematographer would shoot them.

Pick a real camera, lens and film stock, build the shot, then turn it into stills, video, ad layouts and bulk variations. It's a full studio in a browser tab.

  • Cine mode: a virtual camera rack with real bodies (ARRI Alexa 35/65, Sony Venice 2, RED V-Raptor, Panavision XL2, IMAX), their lenses, filters and film stocks like Kodak VISION3.
  • Image mode: 24 photo cameras from Sony, Canon, Leica, Hasselblad and iPhone, with RAW profiles and sizes up to 4K.
  • Prompt builder: subject, action, setting, framing, light and mood as fields, saved as presets so a whole campaign stays consistent.
  • 3D shot designer: orbit, tilt and zoom a virtual camera around the subject to re-shoot the angle, plus storyboards, a 12-pose guide and catalogue sets.
  • Motion: video with Google Veo 3.1 from text, an image or first and last frames, on a multi-shot timeline with camera moves and lip-sync.
  • Design mode: social posts, stories, carousels, posters and web heroes with sharp headline text and logos.
  • Bulk mode: one design becomes 10 marketing angles or colourways, or the same ad in 16+ languages.
  • Analyst and Recolor: break down any image or video shot by shot, or switch a garment to a client's palette pixel for pixel, no AI repaint.

File 02 · Ad dashboard · Version 2

AdSight Pro

What it's forMedia buyers and brand owners who want one clear view of each ad account without wading through Ads Manager.

Connect Facebook once, choose which ad accounts and pages show up, and switch between them. Each report loads in that account's own currency and stays on screen even if a refresh fails.

  • Official Meta login: access tokens are encrypted on the server and never reach the browser.
  • Source picker: finds every ad account and page your login can see; you decide which ones appear.
  • Account switcher: jump between brands; each report loads in its own currency, BDT or USD.
  • The numbers that matter: spend, purchases, cost per purchase and true unique reach, with no double-counted purchases.
  • Where the money went: spend by age and gender, and by platform and device.
  • Private by design: owner-only sign-in, its own database, light and dark themes.

File 03 · Self-hosted email engine

Easy Mail

What it's forRunning your own cold outreach, mailbox warm-up and newsletters without a monthly Lemlist or MailerLite bill.

One web app on my own server, sending from my own mailboxes. Nothing goes out until I've reviewed it, and the moment someone replies, their sequence stops.

  • Sequences: up to 15 steps with merge fields, the recipient's local sending hours and natural random spacing.
  • Stops on reply: a sequence ends for that person when they answer; opt-outs and bounces are suppressed for good.
  • Review before send: every message is previewed, replies are never automatic, and auto-sending stays off until you switch it on.
  • Warm-up: builds a new mailbox's reputation day by day, with daily caps.
  • Newsletters: sent through a separate bulk sender, with double opt-in, signed unsubscribe links and delivery stats.
  • AI writing helper: drafts on free models and moves to the next one if a model is busy; drafts are never sent unreviewed.
  • Inbox and calendar: threaded replies side by side, a schedule you can edit, contacts with tags and CSV import.

File 04 · Mac app · Notes

Zero Notion

What it's forBuilt out of spite, because Notion got slow. A fast, private replacement where every page lives on your own Mac.

The Notion-style editor you know, without the wait. Pages save as you type, search covers every word, and images and videos go to your own Google Drive.

  • Block editor: headings, lists, checklists, tables, quotes and code, a / menu, and pages inside pages.
  • Offline first: everything saves as you type to one file on your Mac; no account to sign up for.
  • Instant search: ⌘K searches the full text of every page, with matches highlighted.
  • Your own Drive: images and videos go to a Zero Notion folder in your Google Drive, cached locally.
  • Bring your workspace: imports a Notion export, attachments included.
  • AI assistant (⌘J): answers questions about your pages, finds pages and writes new ones.
  • Light: about 10 MB on disk, with folders, colour tags, pins and dark mode.

File 05 · World first · Bangla screenwriting

Write On

What it's forThe world's first screenwriting app built for Bangla, for writers of films, series and ads, from the first idea to a storyboard the crew can shoot from.

Start with a prologue, think out loud in a chat, pin ideas to a scene board, write the script in proper format, then turn each scene into a storyboard with generated frames. It runs on my own server.

  • Prologue first: outline, plot, characters, three acts and an optional Story B before the writing rooms unlock.
  • Brain Dump: talk an idea through with the assistant and it becomes a scene card for the right act.
  • Board: scene cards in Act I, II and III, with a continuity check and a nudge when Story B isn't paid off.
  • Real screenplay editor for Bangla: Tab switches line type, character names autocomplete, version history and department notes.
  • Protected PDF export: Bangla script PDFs with correct conjuncts, watermarked and stamped for a named reader.
  • Storyboard: a shot list per scene with lens, camera, film stock and grade, and AI frames that keep your characters' faces.
  • Series and ads: episodes with a season arc, and timed shot strips for commercials.
  • An assistant that doesn't take over: it asks questions and checks continuity and spelling, but never writes your scenes.

File 06 · Mac app · Speech to text

Flowy

What it's forMy own take on Wispr Flow. Hold a key, speak, and clean text lands wherever you're typing, without your voice leaving the Mac.

Talk the way you normally do, with the ums and the corrections. Flowy writes what you meant, in any app.

  • Push to talk: hold Right Option, speak, let go, and the text is pasted at your cursor.
  • Hands-free mode: Right Control + Option starts listening without holding a key.
  • Cleans as it goes: removes ums, uhs and false starts, and fixes punctuation and capitals.
  • Understands corrections: "forty seven dollars, wait no, forty nine" comes out as $49.
  • Any app, 100+ languages: Notes, Mail, Slack or a browser, Bangla included, never translated.
  • 100% on-device: speech recognition and clean-up run on the Mac; no audio or text leaves it, no subscription.

File 07 · World first · Bangla speech to text

Aref Bangla

What it's forThe world's first native Mac app for Bangla speech to text. Bangla speakers type by talking, completely offline.

Press a shortcut anywhere, speak Bangla, and the text is typed at your cursor with punctuation. A companion app turns WhatsApp voice notes and recordings into Bangla text.

  • Dictate anywhere: press ⌃⌥, speak, press again, and the Bangla text appears in any app.
  • Accurate: a 3.0% word error rate on my test set of 10 recorded Bangla sentences, about 2 seconds per sentence.
  • Punctuation built in: । , ? ! added automatically, by fast rules or a local AI that never changes your words.
  • Your vocabulary: custom words for names and places, plus always-replace rules.
  • Transcribe files: drop in WhatsApp voice notes, voice memos, MP3 or video and get Bangla text, saved as a .txt.
  • Mixed language: English parts of a recording are written in English.
  • Fully offline: a Bangla-tuned Whisper model running on the Mac; no cloud calls at all.

File 08 · Android app · Pro camera

Rawsome

What it's forGetting cinema-grade footage out of a Samsung Galaxy Note 10+, past the limits of Samsung's own camera app.

I mapped the phone's camera hardware sensor by sensor, then built a camera app around what it can really do, including the telephoto lens Samsung keeps for its own app.

  • RAW video: every sensor frame saved as true 10-bit RAW and converted to CinemaDNG for grading.
  • Log video: S-Log3 / S-Gamut3.Cine in 10-bit HEVC at a constant bitrate; a 60-second 4K take recorded with zero dropped frames.
  • Unlocked telephoto: opens the 52 mm camera that Samsung only exposes to its own app, plus 14 mm ultra-wide and open-gate 4032×3024.
  • Full manual control: ISO, shutter, white balance in Kelvin and focus, with tap-to-track autofocus.
  • LUT preview: load .cube LUTs and see the graded look while shooting.
  • Fixes Samsung's files: repairs the broken MP4 metadata the phone writes after every take.

File 09 · Chrome extension · Social replies

Moonshine

What it's forWriting replies on X, Instagram and LinkedIn that sound like a real person and make people curious about who wrote them.

A moon button sits next to Reply on every post. It reads the post and the top replies, then offers nine different angles. One click puts the one you like in the reply box.

  • Reads the room: the author, the post and up to 5 top replies, including full long posts on X.
  • Nine styles per click: from Philosopher's Knife to Cryptic One-Liner and Gentle Contrarian.
  • My Style: paste a few of your own comments and it adds a reply in your voice.
  • Per-platform rules: sharp on X, warm on Instagram, professional but human on LinkedIn; never salesy.
  • Insert, copy, refine: drops a reply straight into the box, keeping the @mention on comment replies.
  • Your choice of AI: Gemini, OpenAI, Claude, Grok or MiniMax with your own key.

File 10 · AI workspace

Omni Space

What it's forSmall businesses and marketers who want one place to chat with AI and hand off bigger writing jobs.

Chat for quick answers; Work mode takes a whole task, attached files included, and hands back finished documents to preview and download.

  • Two modes: Omni Chat for conversation, Omni Work for tasks that come back as finished documents.
  • Pick your model: MiniMax or Gemini, switchable per message, each with its cost shown.
  • Your key, your browser: the API key is encrypted and chats stay in your own browser.
  • Web and agent: live web search, or multi-step work with tools.
  • Files in, files out: attach PDFs, Word files and images; download or print the results.
  • Skills and commands: built-in skills, custom ones from a URL, and slash commands.
