Six factual examples, not a ranked shortlist. Suggested checks are not executed-test claims.

CutMargin — Estimate a project margin
Access: The calculator is free and requires no account. An optional $29 kit is separate from the calculation.
Limits: It uses entered fees, expenses and hours; it does not measure time or guarantee earnings. Currency choices do not perform foreign-exchange conversion.
Data: The provider says calculation inputs stay in the browser. Umami collects separate interaction metadata.
Suggested check: Enter a fictional fee and time estimate. Check the calculation before using your own costs.

FlowKit Studio — Keep track of coaching enquiries
Access: Free early access, according to the public product page. No paid subscription amount was verified.
Limits: The current landing page targets coaches, yoga and Pilates. It does not provide scheduling, payment processing or push reminders. CSV and JSON exports are documented.
Data: Records remain in this browser according to the provider. Do not enter health records; there is no verified cloud backup.
Suggested check: Create a fictional prospect and follow-up date. Try the documented export before keeping real records.

HEIC.AI — Convert HEIC photos
Access: Free, without an account or watermark. The published intake limit is 200 files and 50 MB per file.
Limits: These are intake limits, not a guarantee that every device can process a maximum-size batch. Conversion re-encodes files and removes EXIF metadata according to the provider.
Data: Image conversion is described as local. Website analytics and advertising are separate; the site is not represented as tracking-free.
Suggested check: Start with a non-sensitive sample. Check orientation, dimensions and image quality after conversion.

InvoiceAdept — Create a small number of invoices
Access: Free account: 5 invoices/month and 1 user. Pro: GBP 7.99/month with monthly billing, 3 users and unlimited invoices. Pro+: GBP 12.99/month with monthly billing. Prices exclude VAT; a 14-day paid-plan trial is advertised without a card.
Limits: Stripe and WhatsApp features are not included in the free account plan. The product supports records and exports but does not file returns with HMRC. Tax and CIS results need user review.
Data: Account and invoice information is held by the service. The privacy policy identifies hosting and other processors, including Stripe and OpenAI. This check did not send an invoice or process a payment.
Suggested check: Use fictional customer details to inspect the fields and export. Check your tax requirements separately.

RelationCanvas — Map ideas and relationships
Access: Free public access, without an account or export watermark.
Limits: Arrow labels are limited to 100 characters. Longer notes remain in the project rather than appearing in the exported image. Export and large-map reliability were not independently tested.
Data: The provider describes local project work. Keep an exported backup and inspect any sharing link before sending it.
Suggested check: Draw a small example, then check that an export keeps the labels you need.

TextCompare — Compare two versions of text
Access: Free public tools; no account, payment system or subscription is documented.
Limits: File-format fidelity and large-document limits vary by tool and were not comprehensively tested. A textual comparison is not a semantic correctness check.
Data: The privacy policy says comparison content is processed locally. Google Analytics and Cloudflare handle website measurement and technical requests separately.
Suggested check: Paste two non-sensitive paragraphs. Check the highlighted differences against the originals.
