Turtl

Overview

Turtl is a secure notebook for collecting written notes, bookmarks, passwords, images and files, with Spaces for organizing and sharing selected material. It suits people who want a flexible personal notebook that can also be shared or self-hosted. Its strongest case is the combination of varied note types, offline access and user-controlled hosting; its Basic storage cap and invitation-sharing caveat deserve attention.

Key features

Notes, search and writing

Turtl handles both original writing and saved reference material: users can make text, bookmark, password, image and file or document notes. Full-text search and tag filtering make a growing collection more manageable, while Markdown and TeX rendering serve users who want formatted prose or mathematical notation. This breadth is useful for keeping different kinds of personal reference together, though it is not a substitute for a specialist tool where a workflow depends on integrations beyond Chrome and Firefox bookmarking extensions or Android sharing.

Spaces and sharing

Spaces let users group notes and share chosen collections with selected collaborators, assigning permissions from read-only through full ownership. Turtl creates a separate random key for each shared object, so recipients can unlock the material shared with them rather than the entire account. The important caveat is the invitation path: Turtl warns that an email invitation without a separately communicated shared secret can expose a Space if intercepted. Teams handling sensitive material should account for that risk when deciding how to invite collaborators.

Encryption, offline use and hosting

Turtl says it encrypts data in the app before it leaves the device, using keys derived from the user's email and password, and it supports offline access. Users can also import or export a full profile for backup or transfer between servers. The open-source server can be installed for self-hosting, which is a meaningful option for people who want to host their own data. Turtl likely is not HIPAA compliant: its FAQ points to missing access logs, fine-grained access controls and physical access safeguards, so it is not a fit for that compliance requirement.

Pricing

Turtl is freemium, with a free plan, paid plans from $3/mo and a 30-day trial. Basic has no listed price, supports 3 collaborators per Space and caps storage at 50MB. That is a narrow allowance for a notebook intended to hold files and images, making Basic best for light use rather than a shared archive.

Premium costs $3 a month, billed $3/mo, and includes 10GB of note data, 10 collaborators per Space and community support. It is the practical step up for individuals or small groups who need room for attachments and a larger sharing circle. Business costs $8 a month, billed $8/mo, and raises those limits to 50GB and 50 collaborators per Space, with dedicated support; that extra capacity and support suit larger collaborations. Basic and Premium include community support, and Turtl directs users to its community for questions and help.

Platforms

Turtl supports Windows, macOS, Linux and Android, plus Chrome and Firefox bookmarking extensions. Offline access is supported. Self-hosting is also an option for users prepared to install its open-source server.

Who it's for

Turtl is a good match for people who want a single notebook for mixed personal reference, especially when offline use, selective sharing or self-hosting matters. Small groups can use Spaces and graduated permissions to share chosen material without handing over everything. It is a poor choice for HIPAA-regulated work, and the 50MB Basic cap makes the free tier restrictive for attachment-heavy use.

Pros and cons

Pros

• One notebook for varied material: Text, bookmarks, passwords, images and files can live alongside tag filtering and full-text search.
• Controlled collaboration: Spaces support chosen collaborators and permissions from read-only to full ownership.
• Flexible data control: Offline access, profile import and export, and an open-source self-hosted server offer options beyond a hosted-only workflow.

Cons

• Basic is tightly capped: 50MB storage and 3 collaborators per Space limit the usefulness of the free plan for larger collections or teams.
• Invitation handling matters: An intercepted email invitation without a separately shared secret may expose a Space.
• Not suitable for HIPAA compliance: Turtl's FAQ says it likely lacks required safeguards, including access logs and fine-grained controls.

Alternatives

If the priority is a focused secure-notes comparison, browse Secure Notes Apps; for broader notebooks, see Note-taking apps. Readers evaluating business account-based marketing tools should use Account-Based Marketing Software instead: Turtl is a notebook, not an account-based marketing platform.

Abmatic AI is an alternative for account-based marketing: its free plan offers website visitor company reveals, one personalization campaign and basic intent signals. AdRoll offers account-based retargeting with no fee to get started and payment only for media. Hushly has a free tier with PageSherpa access and 50 starting credits. Ploy has a free tier with 500 credits per day, custom domains and Google Workspace integrations. Propensity is a paid alternative with an Essential plan at $2,000/mo for account and contact-level website de-anonymization, intent data and unlimited campaigns and users. Factors.ai offers a Basic plan at $6 a year with up to 10,000 monthly tracked users, 3,000 companies identified per month and 5 seats. Albacross is a paid option with a Starter plan at €84 a month, billed monthly, including 10 verified email credits and 5 verified phone credits. Metadata uses custom scoped proposals whose scope depends on channels, managed ad spend, selected capabilities and delegated work.

Verdict

Choose Turtl if you want a multi-format notebook with offline access, selective Space sharing and the option to host your own data. Its range of note types and permission controls are compelling for personal reference and small-group collaboration, but Basic offers little room for attachments and shared Spaces require care with email invitations. Look elsewhere for HIPAA-regulated work or for a dedicated account-based marketing platform.
