Lessonvault

One reviewed lesson library for every school in a chain

TL;DR Lessonvault gives a school chain one shared library of lesson plans. Teachers start from the best existing plan for a chapter, improve it and send changes to a subject lead for approval, while software checks each plan against the textbook's learning outcomes. The chain pays per school to cut repeated planning work.

The problem

In a chain of 20 schools, 20 Class 7 science teachers usually plan the same chapter separately, and the head of academics has no idea whose plan works. That duplication hurts most when the syllabus changes. In April 2025, CBSE told its schools to move four grades (4, 5, 7 and 8) onto new competency-based NCERT books in a single session, and to run bridge courses of 30 to 45 days alongside[1]. Every affected teacher had to rebuild plans at once.

NEP 2020 says teachers should be kept away from non-teaching administrative work[2]. I found no Indian figure for hours spent on lesson planning, so measure it in your own validation.

The idea

Lessonvault is a private library that belongs to the school group. When a teacher opens a chapter she sees the plans colleagues across the chain have already written, ranked by how often they were reused and what teachers reported afterwards. She copies one, adapts it for her class and can propose her changes back. A subject lead approves what goes into the group's main version.

Software does the checking. It maps each plan to the chapter's stated learning outcomes, flags any outcome no plan covers and spots near-identical plans so the library stays small. Leaders see which chapters have no good plan yet.

I reframed the seed, which pitched AI alignment for every teacher. That part is already free - DIKSHA carries national and state content[3], and global AI teaching assistants offer a free lesson-plan generator for teachers[4]. What no free tool owns is a chain's own tested plans, so that's the product.

Who pays

Teachers use it and the school group pays, through its head of academics or chief academic officer. My test price is ₹15,000–40,000 per school per year, an assumption I haven't checked against any published price. Chains already pay for content and smart-class packages, and classroom-hardware edtechs bundle AI lesson prep with their panels[5], so Lessonvault has to sit beside those purchases and not replace them.

Why now

The 2025-26 book change for Classes 4, 5, 7 and 8 came under NCF 2023[1], so plans written before it are now out of date. In England, Oak National Academy reports that its AI lesson assistant saved teachers 49 minutes a week in an independent trial[6]. Teachers now expect drafting help, which makes a shared library easier to adopt.

Market signal

There is no public figure for what Indian school chains spend on lesson-planning software. The nearest signal is how widely shared material gets used when it's free and trusted. Oak says its resources are used in 72% of schools in England[6], and DIKSHA's app lists more than 5 crore downloads[3].

Neither tells you Indian chains will pay, and that's the number to prove.

Who's already doing this

DIKSHA is the free national platform, covering NCERT, CBSE and 36 states and UTs[3]. Indian classroom-hardware edtechs sell AI lesson prep, homework and quiz tools tied to their panels[5]. A global AI teaching-assistant startup and a big education non-profit give individual teachers free AI planning tools[4][7].

Each of these helps one teacher make content. From their public pages, none centres on a school group's own reviewed library, which is the gap.

How hard is it?

Difficulty Moderate (30/100)
Starting capital ₹35–70 L
Time to launch 4–6 months

Building the library is ordinary software work. Behaviour is the hard part, because teachers must share plans they think of as their own and subject leads must find time to review. Chains also buy slowly and often only at the start of a session, so you get one real sales window a year.

Licences and approvals

No special licence applies to teacher planning software, so only the baseline matters.

  • Company or LLP registration with the MCA before you sign your first school chain.
  • GST registration once you cross the threshold, before invoicing.
  • Shops and Establishments registration under your state's act for your office.
  • DPDP Act compliance before launch. Teacher accounts are personal data, and if you later add student data, under-18s need verifiable guardian consent[8].
  • Content terms in each contract, saying who owns teacher-written plans, and advice on NCERT's terms before you store textbook text. [Requires validation]

Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.

How AI can power this business

  • Plan drafting. Turn a teacher's rough notes into the chain's standard lesson format, which saves the academic team hours of reformatting.
  • Review queue. Flag plans that miss the template, a learning objective or the right chapter, so reviewers start with the weakest ones.
  • Search. Let a teacher in any branch find the best plan for a chapter by asking in plain words.
  • Adaptations. Suggest a simpler or harder version of a plan for a mixed-ability class, for the teacher to edit.

Don't publish AI-drafted plans without a subject reviewer, as wrong facts in a lesson spread to every branch at once.

Biggest risks

  • Teachers do not contribute. If only a few teachers share then the library stays thin and the rest go back to free generators.
  • Bundling by incumbents. Smart-class and content vendors could add a sharing feature to products chains already pay for.
  • Seasonal sales. Missing the April window can delay revenue by a full year.

Our take

It's a sensible, modest business for a founder who has run academics at a school chain and knows its subject leads. If you plan to beat free AI lesson generators on features then don't bother. Prove one thing first - teachers in one 10-school chain reuse colleagues' plans for at least half of the chapters they teach in a term.

Questions founders ask

Plan for roughly ₹35–70 L, mostly on product, onboarding chains and an academic reviewer team.

Do I need a licence to sell lesson planning software to schools in India?

No. Teacher-facing planning software needs no CBSE or state board approval. You need standard company registration, GST and DPDP compliance for teacher accounts.

Can I start a shared lesson library business in another country?

Yes. Oak National Academy shows the model in the UK. Match plans to the local curriculum and check textbook copyright terms.

Talk to Yash

Thinking about building Lessonvault or something close to it? The make-or-break bit is getting teachers to share their plans and leads to review them, and that's the kind of adoption problem I help founders think through. If you need a hand, you know where to find me. Talk to Yash →
