Vana vs OASIS

Vana is open data infrastructure for human-grounded AI, built around a personal server you control on your own device. Connect accounts like Spotify, Oura, and your calendar, see what you have created across platforms, and decide which apps or AI tools get access. The Vana App at app.vana.org is the consumer entry point, while docs and SDKs on GitHub support builders who want user-owned context without rebuilding memory from scratch.

Major AI assistants added proprietary memory in 2025 and 2026, but each keeps context on its own servers and it does not travel when you switch tools. Vana's 2026 App upgrade stores that context locally and exposes it through Portable Memory MCP, so Claude, ChatGPT, and other MCP clients can read from one source you own. That is the trade-off: you manage permissions yourself instead of accepting a platform's walled garden.

Builders use the Data Portability API to ship apps that request data directly from users rather than scraping third-party platforms. The Vana Foundation runs grants, cohorts, and a 1.5 million-person data network for contributors who want their information to create value. Enterprise teams route to OpenDataLabs for licensed training data, separate from the consumer app.

Talk or type a rough idea and OASIS turns it into polished writing in the format you pick, from professional emails to LinkedIn posts or blog drafts. The web app and iOS apps transcribe natural speech, strip filler, and run your words through 20+ rewrite templates so you skip the blank-page stage.

Unlike basic dictation apps that stop at a raw transcript, OASIS lets you select multiple output formats in one pass and build custom templates that define tone, structure, and language. One recording can become five formatted outputs, with credits scaling by length rather than locking you into a single document type.

Students drafting essays, founders writing updates, and professionals cleaning up voice notes before sending are the workflows OASIS describes across its help docs and App Store listing. Free Mode covers on-device transcription only; premium rewrites need an active subscription.

New users get a 30-day trial with 30 credits. Paid Basic and Pro plans start at $4.17 per month on annual billing, with Pro offering 10 times the monthly credits for three times the price.
