Start here — two product paths
Zavent App and Zpectre are direct-license desktop products. Z-ETL
and Zerde are engagement-led infrastructure because the useful
answer depends on the buyer's data, environment, and support
requirements.
TRACK A
Direct-license desktop products
Choose Zavent App or Zpectre, compare monthly, yearly, and
perpetual tiers, then continue to the product buy page.

Engagement-led infrastructure
Contact first, define scope in writing, then receive licensed
builds, integration notes, and support terms for that scope.

Direct-license desktop products
These products can be understood from the public product pages and
purchased from the buy pages. Monthly, yearly, and perpetual tiers
cover the main individual and small-team paths.
DIRECT LICENSE
Zavent App
Desktop workbook surface
- Who it is for
- Individuals and small teams doing local spreadsheet, workbook, and tabular data work.
- What it does
- Opens a local workbook surface for import, inspect, edit, export, snapshot, diff, restore, and provider-configured AI assistance.
- What it does not do
- It is not a hosted BI platform, warehouse, managed ETL service, or document-corpus workbench.
DIRECT LICENSE
Zpectre
Local document workbench
- Who it is for
- People building searchable, inspectable corpora from local documents and file collections.
- What it does
- Processes supported document formats into a local corpus with boundaries, source metadata, review history, and provenance-oriented structure.
- What it does not do
- It is not a spreadsheet editor, a cloud document vault, a generic chatbot, or an anonymous document-ingestion API.
Engagement-led products — what makes an inquiry serious
Z-ETL and Zerde are specific products, not generic consulting labels.
They stay engagement-led because the deployment boundary, data
shape, model/runtime choices, and support expectations materially
change the licensed build and documentation.
- Use it when
- Use when you need high-throughput local or customer-controlled data movement with agreed sources, targets, deployment environment, and support terms.
- Qualify with
- Source systems, file formats, volume, target outputs, deployment host, performance target, audit requirements, and required build flags.
- Delivered as
- Licensed build, integration notes, deployment instructions, and support window defined in the engagement.
- What it is not
- It is not sold as an anonymous public binary, hosted ETL SaaS, or unscoped integration promise.
- Use it when
- Use when you need natural-language-to-SQL or semantic type inference tuned to your schemas, local models, and review tolerance.
- Qualify with
- Schema shape, data source, query classes, false-positive tolerance, model/backend choice, hardware, access controls, and deployment boundary.
- Delivered as
- Scoped local service, schema notes, model/deployment configuration, endpoint availability, and support terms.
- What it is not
- It is not a general-purpose public chatbot, unmanaged database agent, or guarantee that every natural-language question should execute.
Licensing and delivery
Polar handles self-serve checkout for direct-license products.
Engagement-led products use written scope and engagement delivery
instead of anonymous self-serve checkout.
This table scrolls horizontally on small screens. Use arrow keys after focusing the region, or swipe on touch screens.
| Tier | Meaning | After lapse or purchase |
|---|
Monthly | Subscription rental. | Requires an active subscription. No perpetual fallback. |
Yearly | Annual subscription with fallback behavior. | Includes fallback access to the eligible version active when the subscription lapses, subject to product license and entitlement checks. |
Perpetual | One-time purchase for the purchased version. | Includes twelve months of updates. It does not imply unlimited future updates or unlimited support. |
- Choose the direct-license product and tier on the buy page.
- Complete checkout through Polar when a tier link is configured.
- Use Polar receipt, license key, customer portal, and any included download access for the purchased tier.
- Include any Polar reference when contacting support about a purchase.
The public site does not publish anonymous binary links or invented
download commands. Use Contact for purchase support, licensing questions, or scoped engagements.
Support and what happens next
Before purchase
- Review the product fit and license tiers.
- Use monthly for short evaluation if that path matches your need.
- Use contact for product, purchase, or licensing questions.
- For team, suite, or bespoke needs, request a scoped engagement.
After purchase
- Keep the Polar receipt and checkout reference.
- Use the Polar customer portal for subscription and billing operations.
- Contact Zavent support for product, license-key, or activation questions.
- Use the Zavent contact form for product-support questions.
After an engagement inquiry
- Describe the data, deployment boundary, and desired outcome.
- Zavent Data confirms fit and what information is missing.
- Scope, deliverables, support window, and delivery format are agreed in writing.
- Licensed builds and integration notes are delivered against that scope.
Technical notes for evaluators
Keep these as orientation snapshots. Exact build flags, endpoints,
performance targets, model backends, and deployment steps are
finalized in product materials or engagement scope.
Z-ETL implementation snapshot
Pipeline stages are INGEST, TRANSFORM, and OUTPUT.
Common optional build surfaces include DuckDB SQL transforms,
local llama.cpp inference, Lua transforms, and optimized release
builds. Sources and targets are confirmed during scope.
Published posture includes SIMD CSV parsing, ring-buffered
streaming, audit manifests, malformed-row quarantine, and
checkpoint/resume behavior. Treat numeric benchmark claims as
build-and-hardware-specific until confirmed for your environment.
Zerde implementation snapshot
Zerde runs as a local service with health, query, type-inference,
provenance-verification, and model-listing surfaces where they
are included in scope. Endpoint availability is finalized per
engagement.
The evaluation should focus on schema fit, query classes,
review rules, model/backend selection, hardware acceleration,
CPU fallback, and what failures must do before any generated SQL
is allowed to affect production data.
