Ready to Inspect is construction quality assurance and quality control software that enforces photographic evidence requirements through a server-side photo gate.

Security features include encryption, tenant isolation, and exportable records. Finished projects remain accessible indefinitely at no additional cost, even after subscription cancellation.
Seleto gives Brazilian small and medium businesses an "AI employee" that answers their customers on the company's own WhatsApp Business number, day and night. It answers questions about products, prices, opening hours and policies, prepares quotes from what the owner taught it, understands voice notes and photos, books, reschedules and cancels appointments on the included agenda, and remembers each customer's history. When a conversation needs a person (a complaint, a price negotiation, a closed order), it hands it to the team by WhatsApp or e-mail with a summary. It learns from the team's own replies, each one approved by the owner. Setup is done by conversation, with no code, in about 10 minutes. Plans start at R$ 99 per month per AI employee, with no message limits and a 14-day free trial without a card.

Formiary is a form backend for developers and agencies who want submissions that are actually clean. Point any HTML form or frontend at a Formiary endpoint, define a schema for the data you expect, and Formiary validates every submission before it goes anywhere. When input doesn't match, it returns structured, field-level errors your frontend can display directly, so you never have to hand-roll server-side validation again.
Valid submissions trigger automations, so data lands where your team or your clients need it without extra glue code. Agencies can manage forms across multiple client sites from one place, and developers get a predictable API instead of a black box.
Formiary is built for teams who are tired of junk submissions, inconsistent data, and maintaining a backend just to handle a contact form.

Contrato Simples (contratosimples.com) is a Brazilian contract negotiation tool for the step between the client's yes and the signature. Your company uploads the contract it already uses, as a Word file; the system finds the blanks and suggests the fields. The client opens a link, types a 6-digit code sent to their e-mail and reviews the contract in the browser, without creating an account: they select a passage and comment, propose new wording or a new clause. Your company answers each objection in the text itself (accepted, changed, or kept with a reason). Every round becomes a numbered version, and when the client approves, the system issues the final PDF, identical for both parties, to sign in the e-signature tool you already use. In a free pilot with a few Brazilian companies. Not yet: e-signature, AI, post-signature contract management. Product language: Portuguese.
Wuppomat is a volunteer shift planner for organizations that run festivals: sports clubs, schools and their parent associations, parishes and fire brigades. The organizer builds the plan once on a computer: days, tasks like drinks, grill or cash desk, shifts, and things to bring such as cakes. Volunteers sign up on their phone through a link or a QR code on a printed notice, without an account or app. The evening before, every volunteer gets an email with their shift and answers yes or no; if someone cancels, the organizer is told at once and gets a ready message for the group chat. The volunteer page is available in seven languages. One festival day with up to 40 shift places is free; Plus costs 19 € per event, paid by the organization with an invoice including VAT. Volunteers never pay. Data is hosted in Germany.
OverrunShield is a set of browser-based tools for planners, schedulers and project controls staff on construction and infrastructure projects. Upload a Primavera P6 XML or XER file to run a DCMA 14-point and EVM check, open the file without P6, compare a baseline with an update, or rate two to five schedules side by side. Other tools build a P6 schedule, work out earned value, forecast a bid's cash flow, keep a FIDIC, NEC or JCT time-bar register, write a delay notice, price prolongation and lay out an extension of time submission. The free tools need no card and no account; some ask you to confirm your email with a 6-digit code before an upload or download. Paid exports and reports are one-time payments, from $19. The automated checks are a first pass, not a certified expert review.
HYLIGHT is a secure PDF publishing platform for training organizations, associations and course publishers. Upload your manuals and course PDFs, and learners read, highlight and take notes in the browser without downloading a copy.
