I've only been using WriteVoice for a short time, but my initial experience has been very positive.

What impressed me most was how quickly I could capture an idea, search for it later, and then use Custom Instructions to turn a rough voice note into something structured and useful.

I tested it for:

Idea capture
Research requests
Knowledge-base summaries
Search and retrieval

The voice transcription was accurate, search worked well, and the AI rewrite tools helped organize my thoughts into a format I could actually use.

I purchased it primarily to avoid losing ideas and questions before I can write them down. So far it appears to solve that problem.

I haven't tested it long enough to comment on large note libraries or long-term use, but my first impression is very positive.
