Built for geotechnical engineers worldwide. 1 month free on signup. Card required. Cancel any time. Annual prepay saves 17%.
Team includes 20 seats for $799/mo. Add more any time — no upgrade needed.
Every plan already runs all 213 analyses and 47 lab tests. These premium suites — the kind of thing firms license separately for thousands a seat — are optional add-ons you can attach at checkout or anytime from Settings → Store.
Mechanistic-empirical & rigid pavement design
Replaces the AASHTO MEPDG + standalone pavement tools
In-house finite-element solvers
Replaces 2-D / 3-D elasto-plastic FE ($4,649–17,199 / yr per seat) · layered oedometer settlement (~$2,000 / yr)
Pile sections, axial & lateral pile groups
Replaces axial t-z/q-w, pile-group & p-y beam-column tools (~$1,000–2,000 each)
Embedded-wall soil-structure interaction & staged construction
Replaces subgrade-reaction embedded-wall analysis tools (~$3,000–10,000 / yr per seat)
Flat price per organisation — every seat gets the pack. Add or cancel any time.

Replace a 20-seat a legacy per-seat tool setup ($3,000/seat/yr) with TerraBrains Team ($480/seat/yr effective). Save $50,400 per year across 20 seats.
Legacy per-seat tools often cost $3,000–$5,000/seat/yr. TerraBrains is positioned at the AI-native, audit-grade end of that range.
Every paid plan runs the same code-checked engine catalogue — no “pro” tier hiding the real analyses. See all 213 analyses & 47 lab tests →

No SOON badges. No fine-print surprises. If something doesn't answer your question, email hello@terrabrains.ai.
You start a 1-month free trial of the full Team feature set. We take your card up front so there's no interruption later — but you are not charged for 30 days. We email you 7 days and 2 days before the trial ends. Keep using it and it converts automatically to your chosen plan; cancel any time before then from /settings/billing and you pay nothing. Still validating against your own projects? Email support@terrabrains.ai and we'll extend the trial — we want you to be sure before you pay. If you cancel, your data is preserved for 90 days so you can export or come back.
You pick a paid tier (Solo, Studio, Team, or Enterprise) and your card is charged. The trial flips to your chosen plan and we prorate the first invoice for the remainder of the calendar month. If you cancel before the trial ends, you pay nothing — your data is preserved for 90 days, you can read it, you can export AGS/DIGGS, but you can't create new records.
Annual billing saves 17% — you pay for 10 months and get 12. You're committing to a year up front, paid as one invoice (or four quarterly instalments if you ask). Monthly is more flexible but every per-seat price goes up to the monthly rate. Most teams that finish their trial pick annual.
Quotas are hard limits at the database level — the trigger refuses the write if you're at the cap. The UI surfaces a warning when you hit 80% of any limit (active projects, seats, AI queries). You can upgrade instantly from /settings/billing — the change takes effect on the next API call, no downtime, no migration.
Cancel at any time from /settings/billing — your subscription stays active until the end of the period you've paid for (so a monthly cancel keeps access until the next bill date, annual until the anniversary). We don't prorate refunds on partial months. If something goes wrong on our end, email hello@terrabrains.ai and we'll work with you to make it right.
Yes — AGS 4.x and DIGGS 2.x export is available on every paid tier (and the Student tier). You can also bulk-download every report PDF, every borehole log, and every photo from /settings/data. The audit chain hashes go with the export so a third party can independently verify provenance.
It's fully self-serve — no sales call. Enterprise is $1,999/mo flat for the whole organisation: 50 seats included (then +$50/seat), unlimited projects, the full 213-analysis catalogue, every AI feature, the full SHA-256 audit-chain export, SSO sign-in (Google / Microsoft), a DPA and custom procurement, and onboarding help to migrate off legacy tools. On-prem is available by arrangement. Subscribe from /settings/billing in two clicks; for 50+ engineers or on-prem, email hello@terrabrains.ai.
Sign up with a verified .edu, .ac.in, .ac.uk, .edu.au, or equivalent academic email. We auto-issue the Student plan (1 project, 1 seat, free forever). If your institution uses a non-standard domain, email us a current student / faculty ID and we'll flip the plan manually.
Yes — registered NGOs working on disaster-response, slope-failure-mitigation, or capacity-building in low-income regions get the Team tier at the Solo price. Email hello@terrabrains.ai with your registration number.
Volume discounts are built into the per-seat pricing. The /pricing calculator shows the effective per-seat price live as you move the slider. Stacks with the 17% annual discount.
Card required at signup. No SOON badges. No fine-print surprises. Real audit-grade geotech software, free for 30 days, on the Team tier.
