Libby vs. Superpower: Which Health-Data Workflow Fits?

Superpower and Libby are not a simple testing-service-versus-record-app comparison anymore. Superpower includes an annual blood panel and layers a dashboard, imported history, wearable connections, a health protocol, AI, and care access around it. Libby does not order or collect tests; it organizes lab PDFs obtained elsewhere into structured history with PDF and CSV exports.

There is real overlap. Both products now describe historical-lab intake, longitudinal views, and a way to take data out. The decision is therefore not “Which one owns my timeline?” It is which workflow you need, which source facts survive import, what output you can actually use, what remains after cancellation, and which privacy terms apply.

This comparison was checked against first-party pages on July 21, 2026. Features, prices, testing locations, policies, and account behavior can change. Confirm the current checkout and terms before paying or uploading health information.

The old “Superpower tests; Libby remembers” comparison is obsolete. Superpower now says it uploads past labs, tracks them over time, and preserves data access after a member cancels.

The overlap is larger than it looks

Superpower's current how-it-works page says the membership includes an annual panel with more than 100 biomarkers, a dashboard, past-record uploads, wearable connections, a personalized health protocol, care-team support, and member access to add-on tests and products. Its FAQ says results remain in the dashboard for trend viewing and that a member can download or delete their data.

That makes “Superpower keeps only its own annual panel” an unsupported claim. The product spans testing, record aggregation, analysis, and a care marketplace. Its biggest distinction from Libby is the testing-and-guidance system, not the mere existence of a timeline.

Libby's current product workflow starts with lab reports a person already has. It extracts rows from a lab PDF, keeps structured values with dates, units, flags, and available report ranges, and groups repeated markers over time. Libby does not provide a blood draw, laboratory service, prescription marketplace, wearable stream, or health-protocol system.

If the archive is scattered, begin with the source inventory in the guide to organizing years of blood test results. Keep the original reports no matter which dashboard you choose.

If Function is also on the shortlist, the Function Health alternative guide compares its recurring testing and protocol workflow with Libby's narrower record role.

Testing: only Superpower supplies the annual panel

Superpower's current public pages list a $199 annual membership built around one blood draw covering 100+ biomarkers. Its pages also describe laboratory appointments, an at-home draw option, additional testing at member prices, biological-age and health scores, AI chat, a personalized protocol, and access to a care team. Pricing can vary by geography, and add-ons are separate.

The company has multiple live page variants with different counts for partner locations and different at-home draw prices. That is a reason to confirm the specific location, panel, fee, and collection method in checkout rather than copy a number from any comparison page. This article also does not repeat Superpower's member-outcome percentages: its public pages label them as company aggregate analyses, but the pages do not provide enough study detail for an independent effectiveness claim.

Libby's current pricing page lists $250 per year or $29 per month, with a 14-day trial that requires a payment method. That price covers record software, not testing. A fair budget therefore includes the source of every lab, any collection fee, retesting, add-ons, and the record workflow—not just the smallest annual number.

Superpower is the relevant choice between these two if a new panel is the non-negotiable job. Libby cannot replace that collection or laboratory path.

Import: use one difficult report as the test

Superpower says members can upload past labs and medical records and connect wearables including Oura, Whoop, and Apple Health. Its public pages do not give enough detail to promise every accepted file format, every historical marker, or the exact source fields preserved after import. Those are account-level questions to test.

Libby's current public path is narrower: it accepts lab PDFs and extracts structured results. Its membership page describes unlimited upload and parsing. “Unlimited” does not mean every document will parse perfectly, so compare the structured record with the source before moving a larger archive.

Use a report with an unusual unit, an inequality such as “less than,” a flag, and a distinctive reference interval. Check:

• the exact analyte or test name;
• value, qualifier, and original unit;
• collection date and reporting laboratory;
• report flag and report-specific range or cutoff;
• which rows were omitted or corrected; and
• whether the original document remains available for review.

Laboratories can use different methods, units, and reference ranges. MedlinePlus advises reading a result against the range on its own report and cautions against direct cross-laboratory comparison. The guide to understanding lab reference ranges explains why a clean trend line does not by itself establish method equivalence or a personal target.

Guidance: protocol ecosystem versus record organization

Superpower is the broader guidance product. Its current pages describe a personalized protocol across lifestyle, diet, supplements, and fitness; health and biological-age scores; AI chat; prescriptions and supplements when available; and access to a care team. Its membership agreement separates Superpower's wellness platform from medical and professional services delivered by third parties.

These capabilities can be useful to someone who wants one integrated path from testing to suggested next steps. They should still be treated as product output, not as proof of a diagnosis, cause, treatment benefit, or assay comparability. Superpower's own how-it-works page says it complements, rather than replaces, a primary-care clinician.

Libby is less prescriptive. It organizes the report-derived facts and provides PDF or CSV export. Its optional read-only MCP connector can expose bounded record data to supported ChatGPT and Claude clients after authorization. Read-only describes what the connector can do to the Libby record; returned health data still enters the AI service a person chose.

If the destination is a medical appointment, use a focused packet rather than an unfiltered archive. Neither a protocol screen nor a record export replaces clinical interpretation.

Portability: cancellation and termination are different events

Superpower's current FAQ says users can download or delete their data at any time, but it does not specify a download format. Its July 2025 membership agreement adds an important detail: after a member cancels, the member retains access to the account, data, visualizations, and previous treatment plans in the Superpower Data Vault, while concierge, marketplace, and clinical-service access ends.

That is meaningfully more portable than the old article implied. It is not an unlimited guarantee under every exit scenario. Superpower's March 2026 terms of service separately say the company may terminate platform access and generally has no obligation to return content after termination; the terms also tell users to back up information entered into the service.

Libby's membership terms say a person can export PDF or CSV and retain browsing and export after a membership lapses, while adding records, notes, and AI conversations pauses. This is a current product promise, not a substitute for a backup.

Before relying on either exit path, download an artifact and open it outside the account. Check whether it contains the source name, collection date, value, unit, flag, range, qualifiers, and context the next recipient needs. The source-first checklist in how to read blood test results is a useful audit list.

Access after a voluntary cancellation is not the same promise as an export format, a full source archive, or access after platform termination.

Renewal: save the agreement, not the badge

Superpower's public pages say “cancel anytime,” while its membership agreement defines the mechanics. The initial term is one year, renewals occur annually at the then-current non-promotional rate, and a member must deactivate at least 72 hours before the renewal date. The agreement describes a narrow early-refund window before services or platform access have started; after that, fees are generally non-refundable. Cancellation leaves membership access through the current term.

Libby's pricing page says its 14-day trial requires a payment method and then renews at $250 per year or $29 per month until canceled. It says a reminder is sent before the trial ends.

For either service, save the dated checkout, renewal date, cancellation route, and add-on terms. “Cancel anytime” can describe stopping the next renewal rather than receiving a prorated refund for the current term.

Privacy: the published scopes need careful reading

Superpower's FAQ makes categorical security and ownership statements: it says data is encrypted, describes the product as fully compliant with HIPAA, says data is not sold or shared for marketing, and says users can download or delete their data. Its February 2026 privacy policy uses more detailed categories and qualifiers.

The policy says Superpower itself is not a healthcare provider and therefore may not have to comply with HIPAA, while affiliated providers may be covered. It says contracted processors handle health data and AI messages under Business Associate Agreements on Superpower's behalf and not for model training. It also says Superpower may de-identify information and sell that de-identified information, may disclose personal information to marketing and advertising partners in compliance with law, and offers access, correction, deletion, portability, and certain opt-out rights where applicable.

Those statements concern different data categories and relationships; they do not establish that identified health information is sold. They do create questions worth resolving before upload:

• Which entity and policy govern the lab order, app, care team, pharmacy, and connected wearable?
• Is the data in question personal information, healthcare information, or policy-defined de-identified or aggregated data?
• Which marketing, research, product-improvement, and AI uses are optional?
• What does a download contain, and what is retained after a deletion request?
• Which HIPAA or Business Associate Agreement representation applies to this exact relationship?

Libby's public privacy policy explicitly covers the marketing website, not the production app's health-record workflow. It says app health-data encryption, AI-provider retention or training, connector permissions, HIPAA status, and Business Associate Agreement availability need separate confirmation. That scope is not enough to award Libby a privacy win.

How to run a fair comparison

Step 1: define the job

Write down whether you need a new blood test, guided health recommendations, organization for existing reports, or some combination. Do not count wearables, AI, supplements, prescriptions, or exports unless they are part of the workflow you will actually use.

Step 2: review privacy and total cost

Save the exact checkout, geographic pricing, collection fee, add-ons, renewal date, cancellation path, upload policy, privacy policy, export path, retention, and deletion terms. Use a vendor-provided sandbox when available; otherwise use a separate trial account with synthetic data.

Step 3: use the same synthetic packet

Use clearly labeled synthetic files with no patient identifiers or copied patient values. Import the same packet into each product and record accepted file types, processing time, omitted fields, corrections, and support needed.

Step 4: verify export and deletion

Compare every structured field with the synthetic source, open the available download outside each product, and confirm its contents. Delete the synthetic data or trial account as planned and verify the action took effect.

Step 5: use minimal real data only if necessary

If synthetic input cannot exercise a required feature, use real data only after the current terms review. Choose the smallest appropriately redacted, non-urgent sample you are authorized to upload, preserve the source elsewhere, and repeat the export and deletion checks before moving a larger archive.

Which product fits which workflow?

Superpower is a reasonable fit when the primary job is its annual 100+ biomarker panel plus an integrated dashboard, imported history, wearable data, scores, a health protocol, AI, care-team access, and a marketplace. It now has a real historical-record and post-cancellation access story, so it should not be described as a one-panel silo.

Libby is a reasonable fit when testing happens elsewhere and the recurring job is lab-PDF intake, source-aware review, a structured marker timeline, PDF or CSV export, and optional read-only access through supported AI clients. It does not replace Superpower's testing, protocol, care, wearable, or marketplace workflows, and its app-specific privacy terms need direct confirmation.

Using both can be coherent. A person can use Superpower for testing and its integrated guidance, preserve the official laboratory report, and test Libby as a separate lab-history and export workflow. The useful choice is the workflow that survives the source, output, renewal, cost, and privacy checks—not a universal winner.

FAQ

Is Libby a direct alternative to Superpower? Only for part of the workflow. Both products describe historical-lab intake and trends, but Superpower adds annual testing, a protocol, scores, wearables, AI, care access, and a marketplace. Libby focuses on organizing lab PDFs, source review, and PDF or CSV export.

Can Superpower import old lab results? Yes. Its current first-party pages say members can upload past labs and medical records, combine them in the dashboard, and connect wearables. Start with a synthetic test packet because the public pages do not fully specify every accepted format, source field, or marker; use a real sample only after reviewing current terms and minimizing and appropriately redacting non-urgent data.

Does Superpower let me download my data? Its FAQ says users can download or delete data at any time, but it does not name the download format. Test the account's current artifact and confirm whether it contains the source details your clinician, archive, or next tool needs.

Do I lose Superpower data if I cancel? The current membership agreement says a member who cancels retains account, data, visualization, and prior-plan access while concierge, marketplace, and clinical services end. Separate platform-termination terms are broader, so keep independent copies of source reports and downloads.

How much do Superpower and Libby cost? Superpower currently lists a $199 annual base membership with one 100+ biomarker panel, with geographic variation and separate add-ons. Libby lists $250 per year or $29 per month with a 14-day payment-method trial and no lab testing. Confirm checkout before buying.

Which product gives health recommendations? Superpower publishes a personalized protocol, scores, AI, and care-team workflow. Libby organizes lab-record facts and does not supply Superpower's testing or protocol ecosystem. Product output from either service is not a substitute for qualified clinical judgment.

Can results from different laboratories be put on one trend line? Both products describe longitudinal views, but a shared line does not prove two results are analytically interchangeable. Check the source laboratory, method when available, unit, reference range, specimen, date, and qualifiers before interpreting change.

Which product is better for privacy? This review does not assign a winner. Superpower's FAQ and detailed privacy policy use different scopes and data categories that need careful reading; Libby's public policy does not cover production-app health records. Verify the exact data flow and governing terms with each company.
