SaaS & AI

Software you subscribe to — not software you struggle with.

SaaS means "Software as a Service": you open it in a browser or app, pay a small monthly plan, and it keeps getting better on its own. Here are the kinds of SaaS we build, and the new wave of small, focused AI tools called micro-SaaS.

SaaS in simple words

Why businesses are moving to SaaS

☁️

Nothing to install

Open it on your phone or laptop. Your data is safely stored online, not on one computer that can crash.

💳

Small monthly plan

No big upfront cost. Pay monthly or yearly, and upgrade only when you grow.

🔄

Always up to date

New features and security fixes arrive automatically. No reinstalling, no version confusion.

👥

Built for teams

Owner, staff and partners each get their own login and see only what they should.

AI micro-SaaS

Small software. One job. Done brilliantly with AI.

A micro-SaaS is a small online tool that solves one specific problem for one kind of customer, for a small monthly fee. Modern AI makes these tools far more powerful: they can read bills, understand Hindi voice notes, write replies and spot patterns — jobs that used to need a person.

  • Solves one clear, painful problem
  • Built in weeks, not months
  • Low price, so it's an easy "yes" for customers
  • Runs mostly on its own, with AI doing the heavy lifting

AI micro-SaaS ideas

12 AI micro-SaaS tools Indian businesses need

These are ideas we can build, for our own lab or as your own product. Have your own idea? Even better.

💬 WhatsApp reply assistant

Answers common customer questions on WhatsApp (prices, timings, stock) in Hindi or English, and passes tricky ones to you.

🧾 Bill & invoice reader

Snap a photo of a purchase bill. AI reads the items, amounts and GST and puts them into your sheet or accounts.

⏰ Smart payment reminders

Sends polite, timed WhatsApp reminders for dues and EMIs, and tells you who is likely to pay late.

⭐ Google review responder

Drafts professional replies to every Google review in your voice, so your listing looks active and cared for.

🎙️ Voice-note to order

Retailers send a Hindi voice note ("10 pieces of X, 5 of Y"). AI turns it into a clean written order for the distributor.

📅 Compliance due-date keeper

Tracks GST, TDS and licence renewal dates and reminds the owner and accountant in time.

✍️ Product post writer

Writes product descriptions, Instagram captions and offer posts from a photo and a price.

📦 Reorder predictor

Looks at past sales and warns you what will run out soon, and what is turning into dead stock.

🗣️ Customer feedback analyser

Reads reviews, calls and chats and tells you the top three things customers love and hate.

🩺 Patient-friendly report explainer

Turns a lab report into a simple summary for the patient, reviewed and approved by the doctor.

🎯 Lead qualifier

Chats with website and Instagram enquiries, asks the right questions and sends only serious leads to your team.

📄 Resume screener

Helps small businesses shortlist candidates quickly against a simple job checklist, with a person always making the final call.
