Protect the data you collect from censorship, tampering, interception, and destruction.
Easily produce high-quality documentation that can be used for research, advocacy, or transitional justice.
If forms aren’t needed, users can instead upload their files directly to the server in just seconds, or set "auto-upload" as soon as they take photos, videos, or record audio.
If you collect data in remote areas with limited or no internet connection, you can save your data on your device and submit it easily when you reach an internet connection.
When "Verification Mode" is activated, every time you take a photo or a video, or record audio, Tella automatically collects metadata about the file to help others corroborate the evidence.
Tella is currently available in Belarusian, English, French, Portuguese, Russian, and Spanish. And we are always looking to translate Tella into more languages!
