AI Flowchart

AI Flowchart turns written instructions, code logic, and reference images into editable flowcharts in a browser. It suits product, engineering, operations, and support teams that need to map processes quickly and then refine the result. Its broad input and export support make it practical for mixed documentation workflows, provided your usage fits the monthly credit rules.

Overview

You can start with ordinary text, notes, standard operating procedures, sketches, or screenshots rather than building every node manually. The editor also accepts pseudocode and logic steps, which is useful when the structure is already expressed as branches and control flow. Generated diagrams remain editable, either through a chat interface or directly on the canvas.

Image generation accepts PNG, JPG, and WEBP files up to 5MB. That makes photographed whiteboards and existing screen captures viable starting points, although image-based actions can consume more than the one credit used by a standard text-to-flowchart generation. Diagram import is supported, and templates cover approvals, onboarding, support escalation, refunds, data pipelines, and canary deployment.

Key features

Multiple ways to build

Text-to-diagram generation is the straightforward route for policies and process descriptions. Pseudocode input favors technical teams documenting branches, while image input helps convert informal sketches into a structured chart. Chat revision is useful when you want to describe a change conversationally; canvas editing gives precise control afterward.

Portable output

Exports include PNG, SVG, PDF, and editable .drawio files. Raster and document formats cover sharing and presentation, while SVG and Draw.io output preserve more flexibility for downstream editing.

Privacy and operations

Prompts, diagrams, and uploaded images are not published publicly by default. Data transmission uses SSL/TLS, with cloud storage, Supabase authentication, and regular security audits and updates named in the privacy policy. Uploaded reference images are sent to the configured AI provider, and third-party processors may temporarily retain request logs under their own policies. Payment and infrastructure providers include Creem, Cloudflare, and Supabase. Support is offered by email, with most requests answered within one to two business days.

Pricing

The free tier is unusually restrictive for repeated work: even logged-in users receive only two daily credits, and advertising remains in the interface. Pro removes ads and supplies a substantial monthly pool at the lower paid price, but priority support is not included. Premium costs $10 more each month for over three times the Pro credits and priority support, making it the sensible choice for frequent generation or image-heavy workflows. Subscription credits reset each billing cycle and do not roll over, so unused capacity should not be treated as a bank for later projects. Paid pricing is monthly, and generation actions can draw different credit amounts.

Platforms

AI Flowchart runs on the web. A browser-based workflow avoids desktop installation, while teams wanting offline or native applications will need another option.

Who it's for

The tool is a strong match for product, engineering, operations, and support teams translating procedures, approvals, and system interactions into shareable diagrams. It is especially useful when source material is mixed—text for one process, pseudocode for another, and a screenshot or sketch for a third. Casual users can stay on the free tier, but the daily cap makes it unsuitable for sustained project work.

Pros and cons

• Pro: Accepts text, pseudocode, and up-to-5MB PNG, JPG, or WEBP references, so teams can start from the material they already have.
• Pro: Chat and direct-canvas editing support both broad revisions and exact cleanup.
• Pro: PNG, SVG, PDF, and editable Draw.io exports cover presentation, sharing, and continued editing.
• Con: Free use is capped at one or two credits per day and includes ads.
• Con: Subscription credits expire at the billing reset rather than rolling over, and image actions may consume extra credits.
• Con: Reference images are sent to an external AI provider and request logs may be temporarily retained by processors, which matters for confidential material.

Alternatives

Creately is the better pick if you need desktop, API, or self-hosted platform coverage, unlimited canvases and collaborators on its free plan, and a free trial.

InfraSketch suits users seeking a free, cross-platform option for infrastructure-focused work.

Nimbalyst is preferable when MIT-licensed desktop and iOS apps and source availability are priorities.

OpenCharts offers a free-forever tier with 500,000 AI credits, project limits, 10GB of Drive storage, and all export formats.

Lucid Train is worth choosing for an open-source CLI with local models or your own API keys and no account requirement.

AI Diagram Maker is an alternative with API and web access, a 50-credit monthly free tier, and code, SVG, or PNG export.

Archflow fits web users who want a free project-based plan with user stories and a Kanban board.

ArchGPT is an option for a free-forever plan priced in INR with recurring credits and watermarked PNG exports.

Verdict

Choose AI Flowchart when you want one web editor that can turn prose, logic, or images into editable diagrams and export them in both presentation and Draw.io formats. Look elsewhere if you need native or self-hosted deployment, strict control over external image processing, or credit rollover; its monthly reset and low free allowance favor predictable, active subscribers over sporadic heavy projects.
