Molku
Molku is a document automation tool that reads PDFs, spreadsheets, images and Office files, pulls out the fields you point to, and drops them straight into a PDF template or a Google Sheet you supply.
What is Molku?
Molku removes the manual step between two documents: reading a value in one file and typing it into another. You supply a filled example, such as a supplier invoice, a bank statement, a CV or an insurance form, along with the template you want populated, either a PDF or a Google Sheet. You then point at the fields worth extracting, and the tool saves that pair as a reusable workflow.
Extraction is driven by AI rather than by fixed coordinates, so a document whose layout has shifted is still parsed as long as the requested data is present; when a value cannot be found, the run returns an error rather than a guess. Accepted inputs cover PDF, DOC, DOCX, RTF, TXT, CSV, XLS, XLSX, PPT, PPTX, JPG, JPEG, PNG and TIFF, and handwritten text is recognised. Values can be rewritten in transit through plain-language prompts, for instance adding ten percent, keeping only the country from an address, translating a phrase, merging a first and last name, or adding two days to a date. That turns the transfer into a light transformation step instead of a straight copy. Documents carrying a variable number of rows, such as an invoice with three line items one week and ten the next, are handled by declaring spare fields that stay empty when unused.
On a PDF template each field is dragged into position, and a test run on a sample document confirms the mapping before the workflow goes live. From then on, any new file sharing the source structure is processed in one click, and the result can be downloaded, shared through an automatically copied link, or emailed.
Molku is a web application only, built on Bubble.io, with passwordless sign-in by magic link. An open API is documented and Zapier and Make connectors are published, while native Slack, email intake and webhooks are announced as upcoming. Billing runs on credits, one credit per page of input processed, and building a workflow costs nothing. The domain was registered in February 2025, which makes this a young product from an established Bubble studio.
What it does
- Extract named fields from a PDF, Office file, spreadsheet or image using AI
- Autofill a PDF template or a Google Sheet with the extracted values
- Transform values on the way through with plain-language prompts: calculations, translation, reformatting, merging
- Read handwritten text from scanned forms and notes
- Reuse a saved workflow on every new file that shares the same source structure
- Share a finished document by auto-copied link or email, or download it
- Trigger runs from other tools through the open API, Zapier or Make
When to use Molku / When not to
A quick filter to help you decide if Molku is the right fit.
When to use Molku
- Back-office and administrative teams who retype the same values from one document into another every week
- Accounting and bookkeeping staff moving figures out of invoices, bank statements and receipts into reports
- Insurance underwriters and claims handlers filling quotes, ACORD forms and policy paperwork from source files
- Legal support teams turning contracts, affidavits and residence applications into standardised documents
- Logistics and procurement coordinators rebuilding client invoices from supplier packing lists and bills of lading
When not to use Molku
- Anyone needing an offline, self-hosted or on-premise deployment, since Molku is a hosted web app only
- Teams handling highly sensitive or regulated files, which the terms explicitly advise against uploading
- Users who want a mobile app or a browser extension, as neither exists today
- Organisations that require named, revocable access control, because shared documents open to anyone holding the link
- One-off document jobs with no repeating structure, where setting up a workflow costs more time than it saves
How to use Molku
A typical end-to-end flow, from setup to results.
- Create an account with your email address; sign-in uses a magic link, so there is no password to set
- Start a new workflow and upload a Source File, meaning a filled example of the documents you will process
- Upload the Output Template that should receive the data, either a PDF form or a Google Sheet
- Declare the fields to extract, such as names, dates, amounts, invoice numbers or email addresses
- Add a prompt to any field that needs reworking, for example a calculation, a translation or a merge
- Drag each field onto the right spot of the PDF template so the tool knows where the value belongs
- Run the required test on a similar document and check that every value lands where it should
- Save the workflow, which then appears on your home page ready to run
- Upload any new file with the same structure and run the workflow to get a filled document
- Download the result, copy the share link that is placed on your clipboard, or send it on by email
Pros & Cons
Pros
- Genuinely free entry point: 50 credits, no card required, enough to test a workflow end to end
- Unlimited workflows on every plan, so the credit quota is the only real constraint
- Broad input coverage, from Office files and spreadsheets to photographs and handwritten forms
- Prompt-based edits during transfer make the tool useful beyond straight copying
- Clear credit model, one credit per input page, with workflow setup never billed
- Serious security posture on paper: AES 256-bit encryption, TLS in transit, European hosting claimed, DPA offered
- Explicit statement that customer documents are not used to train AI models
Cons
- Almost no corporate transparency: no legal notice, no contact page and no postal address anywhere on the site
- Legal and GDPR contact runs through an email on a third-party domain with no explanation of the link
- Terms and FAQ contradict each other on supported formats, PDF only at 20 MB versus fourteen extensions
- Anyone holding a document link can open it, with no named access control
- No availability, accuracy or turnaround commitment, and remaining credits are forfeited on cancellation
- Web only, with no mobile app, desktop client or browser extension, and several integrations still announced
- The demo request link on the homepage was dead at the time of review

Data, GDPR & hosting
A consolidated view of how Molku handles your data.
GDPR overview
The privacy policy claims adherence to the GDPR for users in the European Union and cites Regulation EU 2016/679 by name. Three lawful bases are given: consent for marketing messages, contractual necessity to deliver the service, and legitimate interest for security, analytics and product improvement. Data subject rights are listed explicitly, covering access, correction, deletion, restriction, objection and portability, exercised by email with a stated 30-day response window. A Data Processing Agreement is offered to EU customers. Two gaps are worth flagging: no Article 27 EU representative is designated anywhere on the site, and no data protection officer is named. The policy is dated 13 February 2025.
Who owns the data?
The terms state that you keep every right to the documents and content you upload. To run the service, you grant Molku a worldwide, non-exclusive, royalty-free licence to use, store and process those documents for the purpose of providing and improving the service. Nothing in the terms transfers ownership. When you share a processed document, the people you choose receive a licence to use, store, copy and distribute it. The privacy policy adds that personal data is never sold, never shared for marketing, and that staff do not manually review document contents. Note that the wording covers improving the service as well as delivering it.
Reuse rights
You may reuse everything Molku produces without asking permission: the filled PDFs and spreadsheets are your own content, and the licence you grant runs in the other direction, from you to the vendor. Downloading, sharing by link, sending by email and collaborating with teammates are all built into the product. The one restriction concerns the vendor's own material rather than your output: you may not copy, modify, republish or reverse-engineer Molku's software, design or branding, and the terms grant no right to its trademarks or logos. Sharing is also technically open, since anyone holding a document link can open it, so treat those links as credentials.
Data retention & training
Hosting summary
The homepage states that Molku is hosted in Europe, with all document data encrypted in transit and at rest, stored on Amazon S3 under AES 256-bit encryption and protected in transit by TLS. Regular backups are advertised. The application layer runs on Bubble.io, which hosts and operates the service, and the privacy policy is more cautious than the homepage: it says the service is provided globally, that data may be processed in different jurisdictions under unspecified safeguards, and that security depends in part on Bubble.io's own infrastructure practices. No specific hosting country is ever named. ISO 27001 and SOC 2 compliance is claimed via AWS, which means the certifications belong to the cloud provider rather than to Molku. A Data Processing Agreement is offered to EU customers. Anyone with a strict data residency requirement should ask the vendor to confirm the exact region in writing, because the public wording does not settle it.
Things to keep in mind
Risks and trade-offs to weigh before adopting Molku.
- Documents are reachable by anyone holding the share link, so a forwarded URL leaks the file to whoever receives it
- Extraction is not guaranteed to be accurate and the vendor declines any warranty, so results must be checked before critical use
- Trusting an automated fill without reviewing it erodes the habit of proof-reading, and a silent mis-mapping is easy to miss
- The terms advise against uploading highly sensitive or regulated data, which limits real-world use in health, legal and finance settings
- Corporate identity is thin, with no address and a third-party contact domain, which complicates any dispute or data request
- Credits are forfeited on cancellation and subscription fees are non-refundable outside legal obligations
- Disputes go to binding JAMS arbitration with a class action waiver, removing recourse to the courts
Setup & Integrations
Technical difficulty
Low. There is nothing to install: you sign up with an email address and log in through a magic link, with no password to manage. Building the first workflow takes a few minutes and involves uploading two files, naming the fields to extract and dragging them onto the template, followed by a mandatory test run. The FAQ claims that anyone comfortable with Word or PowerPoint can complete the setup. Only the optional layers ask for more skill: writing modification prompts takes some trial and error, and the open API, Zapier and Make connectors assume normal integration experience.

Should you pick Molku?
Molku answers a narrow, very real problem: the hours lost retyping values from one document into another. The workflow model is the right shape for that job, since the effort is spent once on a sample file and then amortised over every document that follows. Prompt-based edits during transfer, handwriting recognition and a genuinely usable free tier of 50 credits make it easy to judge the fit before paying anything, and the pricing that follows, from USD 19 to USD 99 per month, sits at the accessible end of the market.
The reservations are less about the product than about the company behind it. There is no legal notice, no contact page and no postal address anywhere on the site; the operator is identifiable only through a single clause of the terms naming Zeroqode, Inc., and both the legal and GDPR contacts run through an email on an unrelated third-party domain. The terms and the FAQ also disagree on something basic, namely which file formats are supported, and the legal documents have not been revised since February 2025 even though the product clearly has. Shared documents open to anyone holding the link, which is convenient but is not access control.
The security claims are reasonable and specific, with encryption at rest and in transit, European hosting, a DPA for EU customers and an explicit no-training statement, though the ISO 27001 and SOC 2 badges belong to the underlying cloud provider rather than to Molku itself. This is a young product, registered in early 2025, from an established Bubble studio. It is worth trialling on the free plan, and worth asking the vendor for its corporate details and a current copy of the terms before committing sensitive paperwork to it.
