Altyst vs Minervian AI: Which Is Better in 2026?

Our Verdict

Altyst and Minervian AI are two of the newest self-serve AI underwriting tools, and they are built on the same idea. You upload an offering memorandum, rent roll or operating statement, the AI pulls the inputs out, and a fixed calculation engine (not a language model) does the math, so the same inputs always produce the same numbers. Both run in the browser, both export to Excel, and both publish low prices. The differences are in depth, breadth and track record.

Altyst is the broader tool. It reads PDFs, spreadsheets, Word files, photos and listing links, names OMs, rent rolls, T-12s, debt quotes and lease schedules as inputs, and flags conflicts between documents with provenance back to the source for every figure. It covers multifamily, office, retail, industrial, self-storage, mixed-use, hotel, land and development, sizes debt on LTV, DSCR or debt yield, and runs base, upside and downside cases. Outputs are an Excel workbook with live formulas, a PDF memo and an editable PowerPoint deck, though scenario and sensitivity results export as values. Plans run from $12 a month for five deals to $99 a month for a five-seat team, billed monthly, with fair-use caps on new deals. The caveats: there is no free tier or trial beyond a sample deal, and its security page says it holds no SOC 2 or ISO 27001 certification.

Minervian AI goes deeper on the modeling engine. It builds a monthly lease-by-lease cash flow with renewal probability, downtime, free rent, TI, leasing commissions and expense stops, a multi-tranche debt stack (construction, bridge, permanent, mezzanine, ground lease, seller financing, fixed or SOFR-based) and an equity waterfall with any number of promote tiers. Live asset classes are office, lab, industrial, retail and market-rate multifamily, with hotel, self-storage, student and senior housing listed as upcoming. The free plan covers five lifetime deals with no card, and CRE Pro is $25 per seat a month for 15 deals, with overage charges per deal and per million AI tokens. The caveats are significant: the company was incorporated in December 2025, the product went live in May 2026, the site names no team members, and there are no independent user reviews yet. Its site also does not say whether the Excel export keeps live formulas.

Neither tool includes market or comps data, so assumptions still need your own research, and both are young enough that you should run a deal you already know through each before trusting it.

Choose Altyst if you want the widest asset class coverage, memo and deck outputs, and an Excel model with live formulas at the lowest monthly price. Choose Minervian AI if your deals turn on lease-level office, industrial or retail cash flows, layered debt and promote structures, and you want to try it free before paying, accepting that it is the newer and less proven of the two.
