INVISIBLE HOUSE
A clean, fast way to look up any Indian mutual fund's NAV history — and compare funds side by side.
Developed by Microintel Data sourced live from mfapi.in
Checking a mutual fund's NAV history today usually means digging through cluttered AMC websites, ad-heavy fintech portals, or PDF factsheets that are outdated the moment they're published. There was no single place to just type a fund name, see its NAV trend, and compare it against other funds — without noise, logins, or paywalls.
Invisible House was built to fix that: a lightweight, no-friction tool that puts fund data first and everything else second.
To make mutual fund NAV data instantly accessible, transparent, and easy to understand for every investor — from someone checking a single SIP to someone actively comparing fund houses before making a decision.
To become the fastest, simplest lens through which anyone can view and compare mutual fund performance — a tool so unobtrusive that it gets out of the way and lets the data speak for itself. The name itself reflects this: an "invisible house" for your fund data — always there, never in the way.
Invisible House solves this with:
- Instant search — type a fund house or scheme name and jump straight to its live NAV data.
- Full NAV history — a complete, scrollable, downloadable record of every NAV entry for a scheme, not just the last few data points.
- Interactive trend charts — zoomable, pannable NAV graphs with quick range filters (1W, 1M, 6M, 1Y, 3Y, 5Y, MAX).
- CAGR at a glance — the annualized return for whichever range you're viewing (1Y and above), or the plain return for shorter windows, updating instantly as you switch ranges.
- Two-point comparison — tap any two points on a chart to instantly see the % and absolute NAV change between them.
- Multi-fund Compare mode — add up to 4 funds and see their NAV trends overlaid on a single graph, each in its own color, with the same range filters, per-fund CAGR, and point-to-point comparison — saved automatically so your comparison survives a page reload.
- Recent searches — quickly return to funds you've looked up before.
- Light / dark themes — for comfortable viewing anywhere.
All of this runs directly in the browser, with no sign-up and no account required.
