Privacy-first document, email, data, and transcription tools

AAAI Tools helps support teams, operators, developers, researchers, and small teams prepare working files before they move into another system. Transcribe short calls or videos, extract document text, inspect email attachments, clean CSV exports, redact JSON examples, convert timestamps, and verify hashes with clear privacy and review limits.

Max 200 MB, 10 minutes, 3 jobs per IP per day.

By uploading, you confirm that you own the media or have permission to process it. Uploaded files and results are deleted after 6 hours.

Outputs

Download plain text for reading, searching, quoting, and archiving. Download SRT subtitles when you need time-coded captions for video editing or publishing workflows.

Privacy

Uploads and results are temporary. Files are stored only long enough to process the job and give you time to download the transcript, then deleted after 6 hours.

Usage limits

Jobs run on a managed processing queue. File size, duration, and daily usage limits keep the free service responsive for everyone.

Start with a real workflow

Instead of choosing a random converter, start from the task you need to finish. These pages connect transcription, document extraction, email inspection, data cleanup, privacy checks, and example inputs that mirror common support and operations work.

Transcription

Review a support call transcript

Turn a short support recording into a draft transcript, then check consent, names, timestamps, and private details before sharing.

 Workflow hub

Practical file and data workflows

Choose a complete path for cleanup, extraction, redaction, timestamp review, checksum verification, or transcript preparation.

 Example

Prepare JSON for a support ticket

Format a failing API payload, remove sensitive values, and build a smaller example that another team can safely inspect.

 Guide

Document extraction QA sample plan

Check extracted PDF, DOCX, RTF, EPUB, EML, XPS, and winmail.dat text before relying on it for review or reporting.

 Privacy

Local vs server processing

See which tools run in the browser, which workflows require temporary uploads, and how long uploaded media is retained.

Frequently used tools

These are the core AAAI Tools workflows: transcribe short media, extract and inspect documents, review email attachments, clean support data, and prepare safe technical examples. Smaller supporting utilities remain available in the full directory.

Who uses AAAI Tools

The site is built for practical file work that happens between larger apps: preparing a support export, checking a document before sharing, creating a vendor-ready JSON example, or turning short media into editable text.

Students and researchers

Extract text from reports, prepare notes from short recordings, count draft length, and keep source files organized before writing or citation work.

Support teams and developers

Format JSON, test regular expressions, decode URL or Base64 values, convert timestamps, and create hashes while preparing vendor tickets or debugging API examples.

Operators and creators

Generate QR codes, clean CSV exports, inspect email or image files, and prepare transcripts or captions for publishing and operations workflows.

How data is handled

Most text, document, and data utilities run in the current browser tab. That means files such as CSV, JSON, DOCX, PDF, EPUB, EML, XPS, images, and short text snippets can often be inspected without sending their contents to AAAI Tools servers.

Transcription is different because speech-to-text processing needs server-side work. Uploaded media is stored temporarily for the job and deleted after 6 hours.

What you can do with AAAI Tools

AAAI Tools combines short media transcription with browser-based utilities for documents, text, data, encoding, and focused work. The tools are designed for small repeatable tasks that should be easy to understand before you use them.

Transcribe and caption media

Convert short audio or video into TXT for review and SRT for subtitle workflows, then edit the result before publishing or sharing it.

Extract document text

Pull readable text from PDF, DOCX, RTF, EPUB, EML, XPS, and winmail.dat files when you need searchable plain text instead of exact layout.

Clean and inspect data

Format JSON, clean CSV files, test regex patterns, convert timestamps, and inspect hashes or metadata before moving data into another workflow.

Use local browser tools

Many utilities run in the current browser tab, reducing unnecessary uploads for tasks such as CSV cleanup, QR generation, text conversion, and file inspection.

How the transcription process works

  1. Upload a supported media file. The transcription tool accepts common audio and video formats such as MP3, MP4, WAV, M4A, MOV, AAC, FLAC, and WebM.
  2. Select the language mode. Use automatic detection for most files, or choose Chinese, English, Japanese, or Korean when you already know the spoken language.
  3. Wait for the queue. Jobs are processed one by one. Shorter, clear recordings usually finish faster than noisy or long recordings.
  4. Download your results. When processing is complete, download TXT for reading and SRT for subtitle workflows.

Best results

Use clear audio, avoid overlapping speakers, and keep background noise low. Automated transcripts can contain mistakes, especially with names, accents, music, technical vocabulary, or low-volume speech. Review the output before publishing or relying on it for important decisions.

Responsible use

AAAI Tools is intended for media you own, created, or have permission to process. Do not upload confidential, private, copyrighted, or sensitive recordings unless you have the rights and consent required for transcription.

Temporary storage

Uploaded files and generated results expire automatically after 6 hours.

Usage limits

The free service limits file size, duration, and daily jobs per IP address to prevent abuse.

No manual review by default

The service is built for automated processing. Technical logs may be used to operate the service and prevent misuse.

Frequently asked questions

Is the transcript always accurate?

No. Speech recognition is an automated process. Accuracy depends on audio quality, speaker clarity, language, background noise, and specialized vocabulary. Always review the transcript before using it publicly.

Why are there upload limits?

Transcription uses server processing resources. Limits keep processing predictable and help prevent a small number of users from blocking the queue for everyone else.

What is the difference between TXT and SRT?

TXT is plain readable text. SRT includes subtitle timing information and is useful when you want to add captions to a video editor or publishing platform.

Can I upload someone else's recording?

Only upload content that you own or have permission to process. You are responsible for following copyright, privacy, consent, workplace, school, and local legal requirements.
