Woleet alternatives. An API-first anchoring service for teams, and a self-serve app for one file at a time.

TimeBinder adds a layer of protection against AI and human fraud and disputes.

A TimeBind is a dated, checkable record that an exact file existed no later than a recorded time and still matches. The fingerprint is made in the browser, and the file stays on your device. Your first Pooled TimeBind is free; after that, TimeBinds start from US$5, and an ASAP TimeBind is US$15.

Woleet alternatives: the short answer

Woleet is a French service that anchors file fingerprints in the Bitcoin blockchain and issues proof receipts. It is built around an API and a dashboard, with plans for timestamping and electronic sealing, and it also offers signature workflows. A TimeBind uses a similar idea for a different audience: one person dating one file in the browser, with a free first record and no subscription.

Woleet is the better choice for teams that need to automate anchoring, integrate with their own systems, add electronic seals or run signature requests. A TimeBind is the lighter choice for a creator, developer or small firm that wants a dated certificate for a file today. Both compute the fingerprint on your side, and both anchor to Bitcoin. Neither proves who made the work. Prices and product facts below were checked on each provider’s official pages on 13 November 2026 and may change. This is general information, not legal advice.

Woleet vs a TimeBind at a glance

	Woleet	TimeBind
What it is	A Bitcoin-anchoring service with an API and dashboard, JSON proofs, electronic seals and signature requests.	A self-serve app that dates an exact file with a certificate and a Bitcoin anchor.
Is the file uploaded?	No. You compute the SHA-256 hash on your side and the platform does not need the file, per Woleet’s documentation.	No. The SHA-256 fingerprint is made in the browser.
Proof format	A proof receipt in the Chainpoint 2 format, with Woleet extensions for seals.	A TimeBind certificate with the Bitcoin transaction reference.
Time to anchor	10 minutes to 6 hours, average 3 hours, depending on Bitcoin network load (Woleet documentation).	Pooled and ASAP options; see the pricing page for how each is recorded.
Who it suits	Businesses and developers who want to automate and integrate, with email support and dispute assistance listed among plan features.	Individuals and small teams dating a file by hand.
Cost (13 Nov 2026)	Timestamping: €19 excl. VAT per month plus €0.15 per additional timestamp. Sealing: €39 excl. VAT per month plus €0.25 per additional seal. 14-day trial per the documentation.	First Pooled TimeBind free; then from US$5, or US$15 for ASAP. No subscription.
Proves who made the file?	No.	No.

When to use which

Use Woleet

You need an API or dashboard to anchor many files from your own systems
You want electronic seals or managed signature requests as well
You want a business plan with support, and are happy to pay monthly

Use a dated file record

You want to date one file or a few files by hand, with no subscription
You want a free first record and a certificate you can hand to others
You want nothing to install or integrate

They can be used together. See also TimeBinder vs OriginStamp, another API-first service, and OpenTimestamps alternatives.

What a TimeBind shows, and what it doesn’t

What it shows

That an exact file existed no later than the recorded time
That a later copy still matches, bit for bit, if the fingerprint is the same

What it doesn’t show

Who made the file, who owns it, or who holds the copyright
That the contents are true, original, or human-made
Whether AI was used, or how a court, platform or insurer will treat the record

The SHA-256 fingerprint is made in your browser. The file is never uploaded. The record is anchored to Bitcoin. This is general information, not legal advice.

Your file’s fingerprint, anchored to a global network secured by real electricity and cryptography.

Editing a file—including with AI—changes its fingerprint, not its existing network record.

How this works

Your file’s SHA-256 fingerprint, a short code worked out from its exact contents, is made in your browser, and the file itself stays on your device. A cryptographic commitment to that fingerprint, which may be combined with others, is then anchored in a block on the Bitcoin blockchain. Bitcoin is secured by proof of work: computers around the world spend real electricity to add each block, and changing an earlier block would mean redoing that work faster than the rest of the network. Until that block is confirmed, your proof is pending. Once the Bitcoin anchoring is confirmed, you can verify the proof against that recorded commitment. The confirmed record can then be checked; Pooled TimeBinds are checked through TimeBinder, while ASAP TimeBinds can also be checked independently. If you check the file later and its fingerprint still matches, that shows the file existed no later than the recorded time. The record doesn’t show who made the file, whether AI was used, or that its contents are true.

Frequently asked questions

Is Woleet a good alternative to TimeBinder?

It depends on the job. Woleet is a French service aimed at businesses and developers: API access, a dashboard, JSON proofs, electronic seals and signature requests. TimeBinder is a self-serve app for dating a file in the browser. If you need to automate hundreds of anchors from your own systems, Woleet’s API is the closer fit.

Does Woleet upload my file?

Woleet’s documentation says you compute the SHA-256 hash of the file on your side, that the platform does not need the file, and that the file is not leaked to Woleet. A TimeBind also keeps the file on your device and records only a fingerprint.

How long does a Woleet anchor take?

Woleet’s documentation says newly created anchors are recorded in the Bitcoin blockchain, which can take from 10 minutes to 6 hours with an average of 3 hours, depending on network load. It also recommends you keep your proof receipts and files yourself.

What does Woleet cost?

Woleet’s pricing page lists timestamping at €19 excluding VAT per month with €0.15 per additional timestamp, and electronic sealing at €39 excluding VAT per month with €0.25 per additional seal. Its documentation also describes a 14-day free trial and plans agreed with Woleet. A first Pooled TimeBind is free, then from US$5, and an ASAP TimeBind is US$15.

Does either one prove I wrote the file?

No. A Woleet proof or a TimeBind shows a fingerprint was recorded by a time. It does not show authorship, ownership or that the contents are true. This is general information, not legal advice.
